xw6400 & xw6600 secret fan: quiet workstations

My best info on tweaking of the workstations xw6400 and xw6600 to run more quietly without increasing the internal temperature when measured with specific utilities has been noticed (and also BIOS) in the xw6600 is attached.

I mention the speed reducers of Noctua fan resistance, 4-wire, and those that work very well for fans of memory and the chipset.  Also, I swapped the xw6600 parts in the xw6400 (fans and broadcasters) the advantage of the most recent HP engineering.

Overall my versions optimized for these workstations run as quiet or more calmly than the Z620, at little cost.  The 4 speed reducers son PWM-preserving you seek are more easily purchased through a pack of 3 of Noctua, found if you google NA-SRC7.  Use one on your memory fan and the other on your chipset fan and fan of memory if you have a xw6600.  Other methods of note are more than a project, but I recommend doing at least the addition of the adapter.

See attachment:

A little added information about fan of little chipset of the xw6600 who run very fast in the xw6600 and is slow.  The Northbridge chipset on the xw6400 has only a radiator... not a fan of any other movement of air attracted on the radiator by the memory fan.  I saw no deficit of cooling by dropping this 3745 up to 2752 chipset fan speed.  About 1 k rpm speed reduction significantly reduced the total noise of work stations, however.  The same concept goes for why add a reducer of Noctua 4 son LNA to fan fan speed memory of the xw6600... lower the speed and noise of the fan with no measurable in time of the memory increase, while maintaining the ability of the motherboard to increase the speed of the fan automatically if necessary.

HP uses the PWM controlled EFB0412HD Delta 40x40x20mm which has one - modifier 7R49 (on the label).  These modifiers to identify fine details of the fan, and for is this it indicates that control PWM has been added, the wires are short and white connect type conventional PWM.

If you never had to get only a replacement fan 3 son he will run to 12VDC full speed, with no gas HP PWM applied.  Here is the RPM:

3-wire (son PWM is unplugged or 3-wire fan): 7500-8500 (measured on several xw6600s)

No adapter and with reference HP PWM applied Butterfly: 3745 (average)

"Adapter 4 son Noctua LNA more reference HP gas: 3101"

"Adapter 4 son Noctua ULNA more reference HP gas: 2752"

Noctua ULNA 4-wire adapters are difficult to get, but at least add in adapters Noctua ULNA NA-RC7 4 wires on your xw6600 fan memory and chipset fan.  Those who are easy to find in a 3-pack by searching for "NA-SRC7.

Attached are the specs of the Delta with the version HD of this fan 12VDC highlighted and a pic of the fan with this modifier code on its label.

  • xw6400 xw6600 xw8400 xw8600: Trim SSD support pilot solution ESB2 xw workstations

    EDIT: IT TURNS OUT THAT THIS PROBLEM EXISTS IN THE W10PRO64 INSTALL ON HP XW WORKSTATIONS AND PROBABLY OTHERS.  SEE THE MAIN 7/16 MESSAGE.

    I worked on a project to help another Member of this forum, and just made a significant breakthrough related to workstations xw, their storage and support TRIM SSD controllers driver version.  I discovered this when working with Hard Disk Sentinel Pro version 4.60, the free trial version.

    It turns out that the Sentinel program can probe a SSD and see what parts of the usual special OS components for the optimization of the SSD are installed, and especially if DECORATIVE knowledge for the SSD is really at work.  In their FAQ, they explain that the operating system can have the function TRIM supported, but this PAD can actually be disabled despite the operating system having received the appropriate command to turn it on.  This is due to hardware (storage controller chipset is perhaps simply not able to do) or software (the version of the driver for this chipset may be unable, but a newer driver may operate properly).

    I fell exactly this problem of driver and bet that few of us knew that this might be the case.  Xw6400, xw6600 and xw8400 xw8600 workstations that all use the same storage ESB2 controller chipset and the xw6600 I was working on a series THAT SSD Intel 320 returned a response to my probe with Hard Disk Sentinel TRIM was supported but disabled.  Another xw6600 with SSD even reported THAT TRIM has been supported and active.  The first was using ESB2 8.6.2.1315 drivers older drivers and the second was using my 'best' favorite ESB2 drivers 10.0.0.1046.

    I ran the normal TRIM check control on the first xw6600 (DisableDeleteNotify fsutil behavior query) and she came back from 0 (which means the TRIM is enabled in my W7Pro64 OS).  Run the cmd as administrator, using an elevated command prompt.  It turns out that 0 operating system response does not mean THAT TRIM is currently working... it just means that it might work if the hardware and the driver have both were sufficient.

    I then updated my driver storage controllers ESB2 via Device Manager for the 64-bit version 10.0.0.1046, re-directed Hard Disk Sentinel, and now have TRIM both supported and active.

    This is an important finding... goal before, with the ESB2 8.6.2.1315 drivers, I could manually run the TRIM of the Intel ToolBox software, but now the operating system can run TRIM automatically, at regular intervals.  I'm just happy that I had already set on this 10.0.0.1046 defined as my drivers of go - to for clean installs a long time ago.  Those who, moreover, are not what you get the installer of HP DVD.  I got them from Intel.  Target the x 64 folder of the Device Manager for travel it driver update method, assuming you are using a 64-bit operating system.

    Note the arrows below, with 3 photos showing (1) a version clone on a disk of a source image of HARD drive, then (2) a clone of build on an SSD of the source image to HARD drive (with the old drivers) and finally (3) build a clone on a SSD HARD drive (with these new drivers installed) image.

    Former pilots and note that Acronis or operating system specific SSD components added automatically:

    Now, with the 10.0.0.1046 new drivers:

    You can use a trial version of Hard Disk Sentinel to confirm whether or not your SSD TRIM feature works actually automatically operating system and if not then try some new drivers of storage controllers and check again.  I found Hard Disk Sentinel to be rather intrusive, so do not keep not installed other than for this type of test.

    I have prepared a number of HP W7Pro64 xw workstations running the activation of W10Pro64 and stumbled upon the fact that the W10Pro64 standard install places older drivers of storage in the setup controller have been recorded previously in W7Pro64 moved to 'support' TRIM but do not have automatic controlled by regular OS TRIM SSD feature enabled.  It has, instead, been 'disabled '.

    It's one thing to manually run TRIM once a month, but you should really have the OS taking care of this task and do not forget.

    For HP workstations that use the storage controller chipset ESB2 and emulation of BIOS SATA value 'RAID + AHCI' or 'RAID' If this other option is not available (same driver install results, whatever) there is a problem.  I have not studied upward in the ZX00 or ZX20/ZX40 generations yet because they use other chipsets and drivers for this task.  ESB2 chipset workstations include the xw6400, xw8400, xw6600, xw8600, more a lot more HP.

    The W10Pro64 install results in automatically install the driver of ESB2 being 8.6.2.1025 with driver date 10/08/10.  With a Hard Disk Sentinel program detects that TRIM SSD is supported but not active:

    After updating the driver for the 10.0.0.1046 more recent version, dated from 13/09/10, the TRIM feature for the operating system has been both took in charge and active:

    I found Hard Disk Sentinel a tool valuable, but a little intrusive, so I install only to such experiences and then uninstall.

    Thus, greeting take is the same for these workstations running W10Pro64 it was when they are run under W7Pro64 (see above messages, 1/16).  Update the 10.0.0.1046 storage ESB2 if controller driver version you want as your SSD that will be automatically triggered by W10 for cleaning PAD regularly.

  • Adding a port series HP xw6600, xw8600, and other workstations

    Based on some advice from Dan_in_WGBU (which is a HP engineer and an excellent source of information in this forum), here's how to add a serial port backplane HP.  To access a serial port still can be very useful for some projects.

    As is done with many more recent work positions the xw6600 and the xw8600 both have no ports series on their basket funds, but HP has designed some of their motherboards with a special type of powered serial port header consisting of two rows of pins... 8 pins on 1 side, 7 on the other.  Who is supposed to accept a cable sheet with a record of 8 holes with a 'white' (filled plastic) which allows the other end go on the motherboard header in only one correct orientation.  For the xw6600 this header is down on the lower edge of the motherboard, just left of the SATA port to the left, under the lowest PCI slot.  It's a '8 x 2 males header' with a single missing pin, which is where plastic filled wil end of shooting overall.  The same device is used with a number of new jobs Z, too.

    The small device at the other end of the ribbon cable is known as a "2nd serial port adaper" since when virtually all workstations had a built-in serial port in the bottom of basket.  With the HP xw6600 and before xw8600 workstations this unit should really be called the "1st serial port adapter".  Dan indicates that this unit can be used on any HP motherboards with special serial port header powered 8 x 2 this necessary.  You can see the unique circuit board at the end of supplypaper-mother of the device below, which receives power from the motherboard to the appropriate serial interface and signals.  Note that this is not a simple transmission device on a cable in water, which is used by some other manufacturers to get signals to/from the motherboard serial port.  Head of series of motherboard HP 8 x 2 location is easy to find in your Workstation Service and technical reference Guide.  These manuals are easy to find via Google.

    Combined perimeter wire / Ribbon / two brackets PCI 'part option' number PA716A, but the key for a cheap purchase on eBay must know he has reference number is 264534-001 283984-001 (alias).  You can find them on eBay in one of these three designations, with the more expensive under the option part number.  Make sure you get the included ribbon cable... Mine cost me about $10.00 total, including shipping.

    XP/W7 32/64-bit OS will recognize this material added automatically, and I bet that Windows 8.1 would be too.  Here is an example of the complete kit, you will get directly from HP, including full-height and low profile PCI brackets.  Many found on eBay are sold without this special ribbon cable coming from the top... Be sure to get one of these.  I bought used... difficult to wear one of these stars:

    I can't post the patterns, but it's OK for me to show the pinout of the connector on the motherboard, since most of them are already in technical reference guides.

    The serial port follows the standard RS232, once the card is installed.  On the motherboard, the serial port UART signals are routed to the Super IO on the connector of P53, but the motherboard is not the interface RS232 circuit needed to provide the interface voltage levels to meet the EIA/TIA-232 standard and to provide ESD protection on the serial port.  So do not try to connect a serial port connector and connect it directly to the motherboard.  It will not work and may damage the motherboard.

    The PA716A card is very simple.  It contains an RS232 interface circuit, more a handful of components ensure the electric compatibility and quality of the signal.  This card is identical to the one used on some HP desktop computers and workstations since about 2002.  If you can get one at a great price, it's probably not worth making your own.

  • XW6600 box MOD not video

    I'll try to make this short.

    I bought a new motherboard XW6600 with:

    Two Xeon 5160

    4 GB of RAM (and four others I bought later)

    A XW8600 PSU I have with a modified Extender I've done (plan I did below).

    Two Seidon Cooler Master 120 v with an adapter by hand.

    A 650 GTX

    It lights up (fans and all work apparently ), RAM and processors heat up, but I get nothing on the screen. In addition, I don't know if the MB will beep or not because I do not know the speaker is going.

    Technical manual troubleshooting pages does not help us either.

    Any ideas? The only thing 'wrong' that remains is the pins on the fans, who do not have the second tachomether, as were fans of the original, but I don't think it's really important.

    Help, please.

    Thank you in advance.

    Do a search in this forum for "pinout" and you will find details on the special pins that are used in the harness to the connector before the xw6400.  Those who are very similar to the pinout for the xw6600 and xw8600 details.

    That should help with the issue of speaker wire...

    The wiring for the fans matter.  Processor for the xw6400 coolers have a jumper wire to pin (ground) to pin 5, but those for the xw6600s have no such rider.  Those who have a set of 4 wire, then one empty 5th pin site.  You can see if you look on eBay at the xw6400 versus xw6600 cooler ends of connector.  Cut the wire to the fan of xw6400 makes the equivalent of a xw6600 fan.  Fans of HP workstation I work with are controlled PWM and the following sequence of 1-4, + 12vDC, sense rpm of the engine to the motherboard, and control signals the motherboard PWM motor circuit.  One of these PWM fans will see rise in RPM if you bring the butterfly wire PWM and just give 12v.  Most of us run fans always at the lowest global setting in the BIOS... for large hot projects, some of us will be ramp their place in the BIOS for the duration of that, then back down the lowest.  I use some bottom of Noctua 4 son and cards ultra low resistance noise my xw6600 dropout fan (ULNA) chipset and memory of the fan RPM (LNA) because the planned values are too high, in my experience.

    With 80 watt processors, you don't hit demand for the motherboard for a 'double height' heatsink / fan that can be integrated with the xw6600s despite the existence only in room for those in the xw8600 (which has a thicker casing).  No xw6600 listed processors have a TDP max beyond 80 watts, but some for the xw8600 do, and motherboard of the xw8600 wants to see the wiring that comes from a processor double height double fan cooler if a processor with TDP max 120W or is in place.  Things get a little complicated.

    I have several xw6400s running of two E5160s (dual core) and I use both of them, if the motherboard cannot run the fastest quadcores for this workstation (E5345s; SLAEJ sSpec code is the latest version).  But you have a motherboard xw6600 , not a xw6400 one.

    These E5160s will not work on the xw6600.  My recommendation for this most recent motherboard is two processors image E5450, sSpec SLBBM (the newest, once again).  If you are running programs that are eager to base that you can run two hearts faster clock speed.  Who all are listed in the latest QuickSpecs, attached.  Two SLBBMs will cost you around $85,00 off eBay these days.

    Always run the latest processor walk because they are of a more recent design of Intel and cost more off eBay in general.  I've never had a xw6600 not to execute what I wanted as long as the processor was in the latest QuickSpecs and I was using the latest BIOS.  This is in contrast with the xw6400 (that question is posted on the forum here, where some cards mothers xw6400 does not have the E5345s and some).

    Be sure to always run the latest version of the BIOS, because there the latest HP patches and the latest "firmware" list that determines which processors can operate in a HP workstation.  Your E5160s are not in the list of firmware xw6600s and does not work.  I tried to get around this rule, a good number of times where both directions and always failed.  Everything simply because of the chipsets on a motherboard HP 'should' accept a processor does not mean that the motherboard will be.  Microcode rule above has not yet been proven wrong.  From my experience if you put a processor unlisted in then BIOS will stop beyond that you currently hold.

    You can go down slower processors for the double xw6600 list eBay market very good heart, and I put out extras.  Start with one of those, then later for two SLBBMs when you get up things and race walk, with BIOS updated.  You end up with a near equivalent Z620 middle level, and this is my preferred approach budget currently.  I add an Intel SATA Gnraton II (3Gbps) 160 or 300 GB series 320 SSD as my boot drive, W7Pro64 and a '2 x 2' USB3.0-oriented HP TI card in the slot PCIe x 16 lower, and I kept 2 k with virtually the same user experience.  I have access to the Z620s to work for comparison and they are great workstations when running the latest BIOS and drivers, but I am very happy with the xw6600 inflated upwards.  In addition, it is a good project.

    Keep us... These coolers look nice.  Maybe you can harvest the fans off the original HP heat sinks and use them.  Have at least one of these fans tuned for your first start for each correct processor.  The motherboard gives the installed memory/processors and the fans present and makes decisions based on this info he sees.  You can usurp the motherboard by some tricks, however, as giving it a CPU fan, he wants to see.

  • Please help, audio problem with XW6600 and NVS 315

    Greetings:

    I just buy a renovated, XW6600 Xeon dual processor, 8 GB of RAM, Windows 7 Professional 64 bit system.  The PC comes with a nVidia NVS 290 graphics card.  Everything works fine and the speaker in the motherboard Jack produces sounds.  However, when I change the NVS 290 with a NVS 315 (it is a HP 720837-001 replacement part), the sound stops working.  The speaker in the systray icon has a red circle with an "x" in it.  If I right click on the speaker, the playback device, it shows two TV as icon one above the other with a red arrow pointing down and a description on the righ side saying "Digital Audio (HDMI) high definition Audio Device not connected.   I have the same result in 64-bit Windows 8.1.  The problem is resolved, if I reinstall the NVS 290.  For both cards, I use the latest version of the nVidia Driver and driver HP.  Am I missing something?

    Any help to solve this problem is greatly appreciated.

    First of all, you want to be sure to load the latest version of the BIOS on this xw6600.  It is from the end of 2012.

    I met this problem several times... do not know if these suggestions will help, but I think that your experience may be related to previous losses audio when the latest drivers are loaded that contain "pilot high-resolution audio" in the game of video driver.

    The current Quadro NVS 315 W7 64 bit graphics drivers Quadro ODE 320.92, which work well in my xw6400, xw6600 and xw8400 workstations running several types of cards Quadro FX and NVS.  If you have used the standard installer downloaded and used the standard "recommended" install that he threw into about 5 pieces, that only one you really need (selected by default single main driver in a custom installation).  That's all I use now, throughout my nVidia installs, and I also check the clean install box on the last page before loading begins in the custom installation path that I go down.   So, to charge fees, I first uninstall anything nVidia via the control panel and then hunt around on drive C for nVidia remains in the trash.  This includes any folder with nVidia in its title, including temporarily enable Show hidden files and folders in the tab views in the Folder Options Control Panel.  I then reboot and finally make this unit "clean install" - checked - technical of custom installation.

    Try this approach first... it's easier.  You might have luck, and audio can return.

    One of the elements that was installed in the "recommended" non-custom installation was a driver of nVidia high-resolution audio.  This seems to conflict with / replace the RealTek driver who was using your audio RealTek chipset on the motherboard.  I discovered that there is a part of BIOS for those workstations which is usually hidden, but sometimes becomes visible with installing drivers high-resolution audio.  F10 in the BIOS, go to the Advanced tab, down for the terminal Options and check if rebalanced Audio appears just above monitor follow-up.  If he was not hidden by the nVidia high-resolution audio driver load then it will virtually always disable status.  Change to activate, F10 to save the change and BIOS don't forget to save changes on exit and F10 again when BIOS asks.

    We got exactly that occur as a result of installing the drivers nVidia GeForce to a GeForce GTX 650 Ti BOOST on a xw8400 and I saw that happen with these latest nVidia Quadro driver packages, too.

    This is the second best method to solve the problem, if it works.

    Another approach is to save your current BIOS settings via replicated in the BIOS Setup, load into my settings to clone xw6600 (attached) and see if the sound comes back like that.  Sometimes integrated Audio remains hidden when we F10 in the BIOS, but my clone settings was set correctly even though the option remains hidden.  You can open the attached CPQSETUP. TXT file with Notepad and Find allows you to do a search for "audio"... the second shot will be the Audio integrated, one.  Note that it is configured to allow this clone... He usually lies in a status of disable, otherwise.

    You can edit it with Notepad, except that, and charge that the version of your original settings of the BIOS using replicated Configuration changed if you want to use this technique with other types of work, such as the xw8600 workstations.  You will always find this entry via this method, even though it is hidden when you look directly into the BIOS, so it's a good thing to know.

    It is the third most easy.

    Fourth... you start dinking autour with drivers in Device Manager.

    Replicated configuration function of the BIOS with a USB, it is very easy to save your original BIOS settings, try another set of settings and return to your original if you wish.  The clone CPQSETUP. TXT file can be edited by hand (with caution) to convert a Disable to activate, for example, saved and then downloaded into your BIOS firmware.  If you want to try attached BIOS xw6600 clone settings make sure to change off the coast of the "xw66002" so that only CPQSETUP. TXT is on your USB... Replicated configuration works which with a file named exactly that.

    I posted here a few days on exactly the configuration of the workstation this clone has been optimized dethrone archive on it.

    Finally, please post back with your findings because it has become a more common problem, and the more data we have here: it is likely, we will find the fastest solution boilerplate.

  • Z210 - temperature max of CPU & cooling concerns

    My Z210 has 16 GB of RAM, a V5900, 2x15K + controller SAS drives video card, a 10K SATA-3 Player and a small SSD.

    RealTemp reports on a typical day, four cores run from 28 ° C to 58 ° C, depending on the load.

    I would like to widen the gap between the highest temperature and max, if there is a way. Might be a little overkill. I don't see any additional fan for the CMT (small Tower) case option. Is that what I could do to cool the computer a bit more?

    DRM for your help!

    Phil and Skylarking,

    I did some research, convoluted and here's what I discovered.  I think that you have found, Phil, is for a rear chassis fan.  Here's the info on the card holders guide/fan front frame for your workstation and other listed workstations.  I saw that a model of HP associated kits front fan over time... a kit at a very reasonable price which includes holder/maps of fan guides plastic black of the workstation several different and a single fan that fits inside included plastic parts.  I guess you're supposed to throw the others.  It is important to purchase the HP kit before they have passed, because the individual parts become hard to find and expensive, later.

    The image of the kit for your workstation shows 3 different guides/owner and a fan.  The black plastic holder/guide you would use is upstairs in the Center.  Note that the one in upper right is only a fan... support no guide slots are present on this one.  Don't know what work, but most likely is for the Z600/Z800:

    Here is a photo of a chassis fan of this workstation and with that color, that I'd be willing to bet that there is a fan with two bars of orientation that HP has used on other workstations for their fans to chassis.   They had that same color brown-orange apertures, for 4 pins, the usual order of wiring PWM, but only the thin lips of direction along each outer edge of the card.  This is in contrast with that HP has used as fan plug ends for memory and chipset, fans, which have 3 bars of orientation.  If you look at the motherboard fan headers, it is easy to see the difference between the two types.  Header of motherboard PWM type (usually white) Cap common 3 grooves will a plastic tab sticking up which only runs the width of 3 of the 4 pins.  2 HP fan PWM header Ridge chassis plug (usually brown-orange) motherboard will have a tab that runs the entire width of all 4 pins.  On my xw6600s memory 92x92x25mm fan and the rear frame paired two cooling fans are the same exact PMW fans except for their part numbers and use of the two different types/colors of the fan plug ends.  The chipset fan plug is also the type of the white Ridge 3.

    Newer workstations such as the Z620 are moving away from these conventions, to a certain extent.

    The chassis before cooling fan on the xw6600 header is for type 2 Ridge connector 4-wire fan, and I've personally seen that also for the xw6400, xw8400, xw8600, Z600 and headers of fan before the Z620 of the workstation.  On the Z620 with that I helped yesterday 2 type of crest of the fan before care was white (instead of the usual color brown-orange HP uses for their taken chassis cooling fan).

    However, the fan will be in the kit and you will get the case HP PWM cooling scheme they have designed in.  I bet it will be the fan in the kit, perhaps without the plastic grid, and those who are nice and quiet:

    If you try to buy by itself you will pay a lot... but check the price for the complete kit from HP below.  The 'Option' HP part number for the kit is A2Z46AA:

    Compatibility is always a problem, and expanding this link from HP homepage, you can see the official info from HP.  Your CMT Z210 is included.  The same fan and the greatest guide support/card fan in the kit would be used for larger jobs.  After working on Z620 recently I think that his kit is different, in the way, and is not in the list of compatibility.  Its front cooling fan looked like a 120mm.  Here is the list of your kit:

    I also found the PDF which shows how to do the installation, and you can find with a goggle «Z210 front fan and fan Support Facility» research  It's attached below.

    I posted here recently on how to "Ghetto Mod" to add to a price in a front 92mm fan to enjoy the front fan on motherboards xw6400/xw6600 header, and leave the PDF file, it seems that method would work here too.  However, $ 15.00 for the complete kit of HP I would go the Mod 'official' way instead.

  • HP XW8400: XW 8400 32 GB of memory

    Hello

    I am suited to 4 GB long ago, however with Adobe applications (photoshop, a) slowing the loading and so now that I chose increase memory up to 32 GB (DDR2-667, DDR2-533 Fully Buffered).

    First in the Cmos - memory has been recognized; then in windows 7 64 bit; the memory has been recognized. And the difference on startup and connection was remarkable - until I started to open the application. For example - all Adobe applications lauch - and then hang - with "not responding". In short, after the upgrade, I am unable to work due to blocking/not responding to conditions.

    At work I may have to delete everything except a memory leaving 4 GB. At least I was able to work - in a very slow process - which is better without working with 32 GB.

    Is there a fix that will allow the correction so that I can use 32 GB of memory without meeting several conditions not respondents not? Office works very well - very fast!

    I would like to know how to repair a harmless memory upgrade - following conditions expected HP upgrade methods.

    Thank you!

    1. install memory by pairs of identical memory modules

    2. do not add not identical memory modules, with which the Office has been delivered. Remove them and set them aside.

    3. install modules of consumer brand that are guaranteed to be compatible with the XW8400 workstation memory

    If you follow these basic rules, then you achieve success through the improvement of memory.

    Your workstation has two processors?

    Examples of guaranteed compatible are two following sites

  • Windows Experience Index score is low... much lower than I think it should be :/

    Hi guys and girls (maybe not so many girls so: P)

    I built my PC around July 2014 and even if I don't use all of the resources I have to my advantage, I intend to use its FULL potential in time to come...

    I built it to do programming, games and Visual editing (in the future) and design.

    I've ALWAYS wanted a liquid cooling and they make it so easy to install, configure and set, not to mention affordable that I went for it...

    I bought the main in order to comply with the new processor "Broadwell" card soon, so I opted for an i5k in the meantime...

    I tweaked and tested (VERY careful I might add) CPU clocks, clocks (voltage Inc.) of memory and GPU clocks (Graphics), BUT...

    I can't get the partition Win Exp Index to 7.9, which I think is unfair! :. (

    I run 3 x 120 mm cooling fans & 1 large liquid CPU cooler cooling to between 1000 to 1500 rpm continuously (gears arranged by fan to create "Forced Induction", to the CPU and the GPU. Thus the two almost never slowed down more than 28' C.

    I have overclocked the processor to 4.5 GHz (Stress tested for an hour and NEVER saw a 55' C). He had @ 4 GHz before so that the cooling fans quieter, but I play with time clocks and the Exp Score win is like a splinter. I can safely 4.6 GHZ clock, but fans fluctuate a little to much for my taste.

    .. then why is my Win Index Score 7.7?

    The score does not change after the settings (clock speed, fan speed)...

    I have overclocked GPU 'Gigabyte GeForce 750Ti OC Version' 1072 (base) 1150 (BOOST) MHz and 2000 RPM @ idle fans. -Without changing partition :(

    I have overclocked memory to 1800 MHz @ 1.62V, which increased the partition Win Index of 7.7 to 7.9 (didn't want to OC it, is fine for my use at the time, but I want to score!)

    Windows really calculate the speed of the CPU, or should I just use the basic CPU specifications?

    On the GPU, it's the "Maxwell" card more slow (to my knowledge), but I have overclocked it to Win Index partition...

    I ran "Catzilla" and the GPU score a 100% before the overclock, the CPU score is 90% @ 4 GHz and "IS" 100% currently to 4.5 GHz.

    Hope you can give me a nice thorough answer on the measurement taken by Win Exp Index procedures.

    And when the "Broadwell" CPU is loose, I will receive the same score when I buy the specification "i5 k?

    Have a good day and thank you in advance :D

    There is absolutely nothing wrong with these numbers even if they were representative of the actual performance.

    As Zig - Zag has already said, they are a GUIDE and a guide is not particularly accurate at this. If your computer's performance are good, and I suspect it is, continue to use it and stop worrying about WEI... :-)

  • HP Z620 workstation: HP Z620 Workstation - WS displays video & Fans Spin loudly or fails - red light with 8 beeps

    Hello

    I have a HP Z620 workstation.

    My processor is an Intel Xeon E5-2660 SR0KK 2.2 GHZ 20 MB 8 GT/s LGA 2011 8 - Core CPU.  More correctly, it's a category of Xeon E5-26xx (dual processor), 8 cores, frequency 2.2 GHz, turbo 5/5/6/6/7/7/8/8, 8 × 256 KB L3 cache 20 MB L2 cache, 95 W TDP, Socket LGA 2011, i/o bus 2 × 8.0 GT/s QPI, × 4 memory DDR3-1600, release date 6 March 2012, CM8062107184801 part number.  This is version 1, not version 2, which is good because the card in my system startup block date 20/12/2011.

    I am using Kingston ValueRAM 16 GB Kit (2x8GB) DDR3 1333 MHz DIMM Desktop Server Memory.   (J'ai également essayer écarter un problème de mémoire utilisé FUREUR de Kingston HyperX 8 GB Kit (2x4Go) 1333 MHz DDR3 CL9 DIMM - black (HX313C9FBK2/8)) as well as herself, to see if that makes a difference.)

    I don't know how to identify my system board other than the one she reads only numbers as "FMB-1102" and "PBLNV0GCY4N0TF" and "such as #618264-001 REV 0 G'.  He has "hp (copyright symbol) 2012 ' and"E93839"and"FXN1"written on it as well.  (After some searching I guess it's card mother 618264-001.  Which differ a card system like 619559-001 - a model later?)

    My graphics card is a XFX R7 240 780 MHz 4 GB DDR3 HDMI DVI VGA graphics card.  (I also try out a video card problem used an EVGA Nvidia GeForce GT 620 1 GB DDR3 SDRAM PCI Express 2.0 x 16 video card to see if it would make a difference.)

    Regarding the power supply, the power supply standard HP Z620 computer PC 800W Power Supply S10-800P1A 623194-002 717019-001.  (I have more than one and who have tried also.)

    With respect to the hard drive, I have formatted and reused a WD Blue 500 GB Desktop hard drive - 7200 RPM SATA 6 Gb / s, 16 MB Cache 3.5 inches - WD5000AAKX.

    My problem:

    1 regardless of what video card I use, if I use the FURY of Kingston HyperX 8 GB Kit (2x4gb) 1333 MHz DDR3 CL9 DIMM - black (HX313C9FBK2/8) memory and starts, I get a blue light, no beeps, no code of message I can say.  However, no tension of the video card (fans not spin) and no power is supplied to the drive hard (do not load and run).  I get a blank screen and can see nothing.  Back fans begin to turn in very strong and turbo mode.

    2 regardless of what video card I use, if I use the Kingston ValueRAM 16 GB Kit (2x8GB) DDR3 1333 MHz DIMM Desktop Memory Server, I get a red light and eight beeps which means a kind of ROM BIOS/CMOS-problem problem problem.  To this end, I tried pressing the button Clear CMOS without result.  I removed the CMOS battery for a sufficient period of time and again.  Nothing changes this situation.  It only happens when I put this special memory in the computer.  If I stick a USB Thumb Drive with file BIOS (BIN) in it which is 3. XX or higher, it will boot to the BIOS on a limited basis.  I also had to understand that I couldn't do anything with a USB keyboard, I could only select options using a PS/2 keyboard - maybe it crashes on some USB devices at this point?

    3. I understand that if I let the rider of recovery from crisis on the 2nd and 3rd pins rather than pins 1 and 2, that it will load from a backup and I can actually do things.   On this basis, I was able to install Windows 10 education 64-bit and a host of programs and otherwise, use the computer normally.  But I can't start unless I have keep that crisis rider of recovery set to pins 2 and 3 and so he can start in the operating system normally by pressing F1.

    4. I while on Windows, updated the BIOS to the latest version, HP Z420/Z620 Workstations system BIOS 3.90 Rev.A (August 8, 2016) using sp77058.exe (19 MB).  I've also updated other drivers as I could with the HP SoftPaq Download Manager (SDM).  None of this changes the problem at initial boot upward.  At the start he complains front chassis fan does not turn, but this is not a problem I have printing allows to stop a boot to the top, it would give just a warning and still boot normally.

    Well my computer works and does that as long as I keep this crisis recovery jumper on.  But I feel that I should be able to solve the problem and he can begin without interference and without resorting to a measure as drastic.  Suggestions anyone?

    Thanks in advance for your time.

    MR. J.

    Juggerknight,

    Keep the rider of recovery of block starting on pins 2 and 3 of E15.  It's 'off' because the 3 pin is not connected.  Put the jumper to pins 2 to 3 "parks" the rider.  Put the jumper on pins 1-2 active boot block recovery mode, and the system does not start with the jumper in this position 'on '.  (You have already discovered this)

    In addition, do not mix unbuffered and registered in the same system memory.  Use either one or the other.

  • W100: speakers too quiet - loud fan

    Hello

    I use the w100 - 10 d and I am not amused on the volume on the fan and
    the speakers. The fan is too loud and the speakers are very quiet.

    Is someone here who can give me some information on stakeholders and their configuration?
    In Windows 7 and Toshiba Conf. Panel sound level is on maximum level, but the sound is too quiet.
    Toshiba is perhaps to estimate that all users use headphones?

    Thank you

    > Is there, anyone can give me some information on stakeholders and their configuration?
    > In Windows 7 and Toshiba Conf. Panel sound level is on maximum level, but the sound is too quiet.

    This booklet is a kind of Tablet PC, a small display 7 I know what speaker volume you expect, but you will not get the same volume as on 15 laptop equipped with larger speakers.
    Furthermore, the speakers are not stereo and mono.

    By the way; the sound can be configured in the control panel-> sound
    Check if all volume controls are set at the beginning.

  • HP xw6400 Workstation doesn't Boot Up

    My husband has a HP XW6400 workstation won't boot to the top.  Two beeps four times during a red light on the front flashes four times, or it will be as it tries to start, stop, and then resume, then stop.  Once he has me completely in the Windows 7 boot screen, then turns off.  We have removed the RAM & reset, but it does not solve the problem.  Any suggestions on what could be the problem?

    The last time he tried starting, a black screen came with rerarding of different options start in safe mode, repair mode, etc.  He chose safe mode & that's when he started having this problem.

    He went to the store to get a new CMOS battery for it.

    Thank you!

    It's the kind of help your Boyfriend... Here is some info.

    The diagnostic model beep by HP in their workstations has been fairly constant.  4 beeps then 2 second pause, and means a power failure in the broad sense.  Food can be very good, but something attached to it can cause problems and point the finger food.  There is a safety circuit at the top end power supplies that can cut them very quickly... a "crowbar circuit.  Go to the search bar who said 'Search in the HP Forum' and type in 'crowbar', and then "4 beeps".  You will see a little info.

    If you google xw6400 technical and manual repair you can find a searchable PDF version of this document and get added information when you do a search in there for 4 beeps.  It tells you how to test that the power is good or not... I met the 4 beeps in the past and it was a bad power supply only once (usually, it's something else down the line that causes the same fault-circuit activate).  HP power supply replacements are cheap off eBay as companies out of these and get them out.  In my case there was some video cards causing the crowbar circuit activate, so also try a spare video card if you have one.  Pretty much whatever it is connected to the power supply can trigger, but it is rare to be triggered internally.

    Better to completely disconnect (power and data cables), but the basics and build backups since then.  You can usually find the culprit in this way (assuming that it is not the power supply itself).

    Let us know what it was... the CMOS battery is not likely the issue.  Good to replace those every time than in quite awhile, so no loss.

  • HP Z820 workstation: Z820 HP does start, fans at high speed, no BIOS, no signal in the monitor.

    Hello world

    My listing of workstation: HP Z820, Dual Xeon E5-2687W @ 3.1 - 3, 8 GHz, graphic card Nvidia quadro K5000, 64 GB RAM, 2 x 500 GB HARD drive.
    The workstation is still under warranty.

    They arrived after upgrade to Windows 10 (from 8.1 to Windows) and put such BIOS updated as recommended by HP support Assistant.

    I was on the process to refresh the 10 Windows , then the system automatically tried rebooting to complete the update, but he never did it again! and then the fans running at full speed. After waiting for 2-3 minutes, I had to hold the power button to turn off the computer.

    After waiting for about 10 minutes, I tried to start the computer, but the same thing happened: you press the button power and then after about a minute , fans rotating at high speed, no signal, no BIOS, no noise, no power in the keyboard or mouse, the blue LED light to the rear.

    So I let the computer without power for 7 hours... (The power cable is disconnected).

    At 11:00: reconnected the power cable (HDD and DVD ROM are DISCONNECTED) and tried to start but the same thing happened.

    Now, I'm on google to find a solution:

    1. power? (Have not yet been tested food.)
    2 motherboard? No damage to the capacitors or anything else.
    3 reset the BIOS/CMOS? (Power disconnected cable) Removed the battery and put it back it, held the CMOS button for 5 seconds.
    4 graphics card? Replaced the K5000 Quadro with a Quadro 4000.
    5. exercise of the power of the system? held the power button with the power cord unplugged for 30 seconds.

    None of the above solves the problem but now when you press the power button / the fans start to run at high speed immediately! This got worse?

    Any help would be greatly appreciated. Thank you.

    The problem is a faulty motherboard and it was replaced under warranty.

  • xw6600 Workstation - Serial Port problems

    I want to add a standard RS232 9 pins (serial) port on my HP xw6600 workstation.

    Due to the current expansion I have only x 8 PCIe and PCIe x 16 available on the motherboard slots.

    I tried two dedicated PCIe Searial maps (PX-235 BrainBoxes and SatrTech BY - 1 S 552) and caused both the PC go into a continuous re-start cycle, i.e. the PC through the BIOS and rebooting itself before loading the operating system.  I tried to disable the interface Serial Port built into the BIOS, but it made no difference and cars (s) should be removed.

    I noticed that the motherboard has an onbard Serial Port adapter, but I don't know what hardware is required to present this port at the rear of the workstation (cable and plate back I guess), or even if it can be used for this purpose.

    If someone added a serial port to the device, I'd be interested to know how they did it.

    Thank you.

    That's what you're looking for. It is a connector standard seial that connects to the head set to edge out motherboard to an empty slot on the back of your pc. There are many on the market. You should be able to find a room for @ $6-8, 00 USD to any electronic parts store. If you activate the serial port in the BIOS, coupled with the installation of a configuration like this, you should have what you are looking for.
