• CPU Upgrade for Optiplex 755 - Core 2 Quad?

  Hey guys!

  I have a Dell Optiplex 755 desktop computer. It's a SFF, and I picked up the recycling room in my office. It just need a HD fan, and it runs great. He got a Core 2 vPro 3.0 ghz in there at the moment, 4 MB of cache and FSB 1333.

  It works well, but I would like to upgrade to a slightly faster processor and I am considering my options. I watched the fastest Core 2 Duo, I couldn't, and they offer only a 3.33 ghz, however, it's something like $350 dollars for the processor.

  I started thinking maybe I should see what there is and realized that there is also the Core 2 Quad and the Extreeme of 2 Core that are available with one cache of FSB 1333 mhz, and PGA775 (or other).

  I'm curious, but you guys don't know if it is possible to install a Core 2 Quad or a Core 2 Extreme in my Dell Optiplex 755? This PDF shows on Page 10 to take a Core 2 Quad. http://www.Dell.com/downloads/global/products/Optix/en/opti_755_techspecs.PDF

  Which is the maximum that the BIOS will recognize / support? Can I use a QX6850?

  Thank you guys!

• Upgrade CPU OptiPlex 755?

  I have an Optiplex 755 of sff with the q6600 and Im thinking about buying a mini tour with the q6600 as 755. I know that I can move to the q9650, q9550 or q9450, no problem. But what about the xeon x 3350, x 3360 x 3370 3380 x, x 3353, x 3363? Specifically the x 3363 because his 80w so I can use the hsf stock; and you can find them for really cheap.

  I know that they are not officially supported by dell, but I saw references it will work online.

  And it would be a possible upgrade being the q6600 2.4 ghz, 8 MB L2, 1066fsb, 105w. 3363 x is 2.83 ghz, 12 MB L2, 1333 fsb and 80w.

  My PC is used for folding at home, General internet surfing and use htpc. I want just the processing power as much as possible of my old system.

  Recently installed a LGA 771 Xeon X 3363 CPU in one of my computers Dell Optiplex 755 with a LGA 771-to-775 adapter: http://valid.canardpc.com/dxczhe

  Very happy because the 3363 X is faster than the Core 2 Quad Q9650 and the Xeon E5450 evaluated!

• Video upgrade - business multi-screen on Optiplex 755 MT

  People,

  Please, let me share my upgrade of success a good end of the Dell Optiplex 755 MT for multi-monitor lease.

  If you are looking to use a great system for companies, but want to add multiple monitors (which is fantastic for productivity), so this solution might be nice for you.  And do graphics multi-monitor solution that works is easy and difficult at the same time!   It's easy if all the material is known to work together!  This note is therefore, on this topic.

  * With the help of ATI over-pants 2450 in 16th housing PCI Express.

  * Four monitors (via VGA or DVI adapters included) OVER the motherboard video still works!

  * Updated the BIOS to the most recent.

  * Note that this card works PCI 2.0, and it works in what is apparently a PCIe 1 location. on the MOBO 755 0 a.  A 2.1 card may not work.

  * This is for businesses and all five monitors work fine now, even with YouTube.  This is not intended as a game environment.

  * There are a few things to try in BIOS in terms of parameters - for a while, there was a mistake of memory and the thing wouldn't start - it took a little time to understand the exact configuration of he.

  * WIndows 7 is the operating system used - and Windows Aero works.

  * I'm not long seen accidents associated with old Jaton NVidia PCI cards that we used previously.

  * The physical slot size are fine.

  * Consumption looks very good.

  * Cost of ITX Canada was about $250 more shipping, tax etc.

  * Here's the Sapphire version of the AMD ATI card, which is very good.

  * The AMD reference number is 100-505531.

  Five monitors are not identical (three different geometries and two sellers)

  * Device Manager lists the latest AMD video drivers for this card as installed and work - I am not quite clear if the drivers have been installed from the download, or later.

  Actual installation was required for their persistence and a little hairy.  When I reboot, I'll see all noting the exact BIOS settings.

  * The system crashed not once now, in a week of constant availability, including browsers open 20 tablets or more periods and use of the physical memory of 80%.

  * System 6 GB of RAM, running 64-bit and BIOS A22.

  Good luck.

• No POST after CPU Upgrade OptiPlex 755

  Just try to upgrade CPU of my Dell OptiPlex 755 Celeron to Core 2 Quad 9650 430. After swapping CPU, CPU fan runs, light on the card mother and some long deep, but not post.  Help, please.

  Are you sure it's a CPU supported?

  You upgrade to the latest version of the BIOS before you swapped processors?

  Are you sure that it is positioned correctly in the socket?

• OptiPlex 755 memory upgrade - which slots to use.

  I just upgraded the memory on my Optiplex 755. He originally had 4 512M memory locations and I replaced two 512M sticks with 2 G sticks.

  (Perhaps mistakenly), I put new memory in the slots of alternative, so that memory is now as:

  1 2 DIMM
  DIMM 3 512 M
  2 2 DIMM
  DIMM 4 512 M

  Everything seems to work OK.

  Can someone advise please if this is the correct configuration and if the configuration is incorrect, there is a significant success in performance?

  Thank you very much.

• Is a processor upgrade Optiplex 755 worth the cost and effort?

  I have a 755 core 2 duo 3 Ghz 1333 FSB running Windows 7.

  Is the cost and effort to upgrade the processor to a quad core is worthwhile, given the age of the computer?

  Would be a quad core overclocking more slowly or more slow FSB no improvement in speed over the 3 GHz Core 2.

  Looking at eBay and amazon Q9650 (3 GHz) runs around $100, the Q9550 (2.83 GHz) about $75.

  The slower Quad cores are $30 - $40, which I wouldn't mind if it makes a noticeable improvement.

  Not sure I want to put another $100 in there, unless it's a very big improvement.

  Thank you

  You should see an improvement in performance, but I don't know how. On average, what is your current CPU usage in Task Manager? If it is maxed out at 100%, a large part of the time, moving to a quad core should offer a significant improvement. If it is 50-60% most of the time, maybe it's not that big of an improvement. Here is a list of media UC the OptiPlex 755:

  3.00 GHz, Quad Core Yorkfield Q9650, 12MB
  Yorkfield 2.83 GHz Quad Core Q9550 12 MB, 1333 MHz FSB, E0
  2.66 GHz, Quad Core Yorkfield Q9400, 6Mo, 1333FSB, R0
  2.66 GHz, Quad Core Kentsfield Q6700, 8 MB, 1066FSB, G0

  The Q9650 both the Q9550 should work in your machine. I hope this helps!

• Upgrading OptiPlex 755/heatsink?

  Hello.  I am the proud owner of a Minitour Optiplex 755 (it's the largest, right?).  I would exchange its current E8400 for a quad core CPU.  I have yet to decide on which one, but my assumption is that all the quads would be hotter than a CPU dual core.  I might be worth mentioning that the PC came originally with an E6750.

  Since the Optiplex (mostly Dells?) using a heat sink assembly / fan non-standard Cpu, my question is this: Dell did use the same radiator/fans regardless of whether if the PC comes with a dual core or quad core CPU? Or do you have a heatsink / fan is enough to cool the dual AND Quad enough?  OK, that's 2.

  I looked online for a radiator that is specifically for a 755 with a quad core, but found only the standard one I currently have in my own 755.

  Thank you.

  Update the BIOS for the 755 is as A20 I think.  HIGHLY RECOMMENDED to update the BIOS BEFORE installing a cpu update.

• What graphics card to Optiplex 755?

  I read some interesting things lately, like ' players not to buy jobs ', and there is really not much difference between a high-end workstation graphics card and a high-end card gamer, except the stabile, the ability to render OpenGL drivers and the price, price, price!

  Well, I like the stability, durability and support of a professional computer, so here I am with an Optiplex 755 w / Wolfedale E8400 Core duo 3.0 MHz, cache 6 MB L2, 1333 bus FS. It came with memory 667 MHz instead of 800, but it seems that 667 DDR must be able to feed the 1333 FSB well enough. I just upgraded the RAM max 4 g w / XP Pro 32-bit. Not too bad a machine, to what I studied put them in a graphics card. I must say that I'm not a gamer, but would like to try a few games, maybe FlightSim. I intend to make a video montage of family videos, and wants to rapid processing and output quality. I was called to splash around to be a hardware geek from time to time.

  I knew that slot PCIE-16 version 1.0, so the 1/2 the speed of 2.0. Somehow, I thought that the graphics card would determine the speed, but it was a chimera. Someone told me that PCIE 2.0 cards would not work with a 1.0 interface. (It is also only 1 slot, so no Crossfire or SLI.)

  So I started looking on the cards in PCIE 1.0 game more fast, the 8800 GTS 320 M and 640M. However, I am worried about the basic things 2 - editing of the card in the machine and do not FRY machine. The slot itself is marked 75 W. All comments graphics card I've seen recently are beginning to 130W consumption at idle and go up to perhaps 250W + dependent. What gives? Can someone tell me what means the restriction of 75W Optiplex 755 PCIE-16, and how to know what cards he meet.

  Also, I came to realize after some time and read some post here the mobo is actually an upside in the Optiplex 755 minitower. If you look at the front of the computer almost all the time - all other Dell and most computers I saw - the motherboard is on the right. In the Optiplex 755 system is on the left! This means that the graphics card must go up the face in the PCIE slot. That in itself is more logical, that hot air would rise out of the heat sink, rather than having trapped under the Board (see solutions of Zalman heatsink of heat). However, Dell Engineers put the PCIE slot at the top of the expansion slot. This means no double height, that are better cooled cards. There is also the heatsink shroud / huge CPU fan and case relatively shallow, making it probably can't get a card of 9 or 10 in in the machine. Goodbye 8800 GTS (unless he can stand up and there is a single height - prob 320Mo - ones that work pretty cool)? Opinion, please!

  I found a great deal in a map of the workstation - ATI FireGL V7200 - with total memory 40 GB/s bandwidth and an extension of the removable card, so the length of the map would be good. But guess what, it's the double-height! If only there was a way to hack off the grilled second slot cover, or somehow bend it to fit in the case without voiding warranty! Very frustrating!

  It seems that I am stuck with the 8600 GTS, unless someone can tell me otherwise - please! 512 M GDDR3 is important, but bandwidth total memory is the key - 32Gbytes/s, it is at least half of the 8800 GTS.

  So the next concern is the heat dissipation. When the heat emerges from the graphics card, if all goes well it will drift away from the CPU and not get drawn by the CPU fan on the heatsink for the CPU! Or elevation to kill my memory cards! What is your opinion on this concern? I have to / can I put an almost opposite case fan the CPU fan? Talk at cross-purposes. What about an expansion slot fan? Below of the graphics card, I don't know how much good it would do.

  I found the solution to food. It's a power PC and cooling 500W Dell special edition with 2 metal connectors that are necessary to justify the power supply at the top of the case. I do not think that it is possible to interrupt the power supply comes from the screws? So, which limits your choice of power supply. I had looked at other power supplies, like the OCZ / StealthXStream / 600 watts, but I wonder if that will be suspended correctly. In addition, fan PSU on the bottom of it might be a good thing? -draw the hot air on the top of the graphics card in the power supply? Maybe a bad thing, but the air flow case is generally supposed to be good.

  And then, if I get the 8600 GTS, I don't need a new power supply. I found a post here that says than 305 w as I have a nominal 12V 18 a. well, 8600 GTS needs 30A. BTW, the XFX is a good card? -that looks like what I want to come to - guaranteed for life! I guess that EVGA is an alternative, but I can't find an EVGA 8600 GTS 512 MB DDR3 cheap.

  I'm looking forward to hear your comments and suggestions on a graphics card - less than $200, please! Thank you.

  
  

• Dell Optiplex 755 SFF - How: maximum performance?

  Reference Dell dear users.

  I have a Dell Optiplex 755 SFF, and I would change all my materials for the best components that I can use.

  Is it possible to upgrade my processor Q6600 to a Q9550 / Q9650?

  I know there is no Q9550/Q9650 on the compatibility list, but I saw someone put the CPU into this motherboard, and he said that he works very well with this motherboard. So, what is your suggestion? I would like to give it a try? Will it work? Or is it just a complete?

  Is it possible to put a primary HARD drive and a secondary SSD in the system?

  If this is the case, what is your suggestions? I thought about a 120 GB SSD system and a 1 TB Western Digital HARD drive, it's a good combination? (7200 RPM, SATA)

  Who is the STRONGEST Videocard for its price, which can adapt to this mobo?

  Many people say LP 7750 HD is the best of what you can get, but I checked ebay and other Web sites, even sought a 7750 HD LP "pre-owned", but I could not find. What video card do you offer me?

  ((Current))

  Q6600

  RAM 2 GB (1x2Go)

  INTEL GMA3100 (: C)

  150 GB HARD DRIVE

  PSU 275W

  Thank you!

  7750 (now called profile low 250 R7) uses more than 25W you run the risk of damaging your system.

  Low Profile Fanless Silent ASUS EAH6450 to 27W is the max I would use.

• OptiPlex 755 denies access to the boot sequence menu.

  Found a weird problem on an Optiplex 755 Desktop Tower System.

  I can change other values available on the system, but cannot get into the boot sequence menu.  The BIOS that was on the system was A17.

  Updated the A20. No change.

  Oh. It wasn't later. Upgrade to A21.  No change.

  Downgraded to A12.  No change. Faced A21. No change.

  Demoted in A10. No change. Faced A21. No change.

  Decommissioned at A01. No change. A21 encountered no change.

  If there is a password on the system when I tried to access the boot sequence menu it reminded me that I needed to type first. After correctly entering this value, the guest went away, but I still couldn't get into the boot sequence.

  I removed the battery cmos for 20 minutes while the system has been disabled, it put, started. No change.

  I replaced the battery cmos with that of another system.  No change.

  Tried another keyboard. No change.

  The jumper to reset the cmos.  No change.  A run the utilities on board.  No error could be found.

  If I hold the Enter key while on the boot sequence menu I can see the screen initial start-up and glimmers of it will not advance to the next screen.

  Unplugged the system and pressed the button for 30 to 60 seconds. No change.

  I think it's ripe for a replacement under warranty.

  Event_Horizon.

  I know that this response comes a little late, but for someone else has this problem...

  IT CAN BE FIXED!

  This problem seems to arise after a BIOS updated completely flashing properly. That leaves the user unable to change the boot device priority in BIOS, causing therefore the machine complaining that there, there is "No Boot Device available"

  Making level and the average standard BIOS downgrade do not seem to work; However with some switches it can be done.

  First of all, you need the BIOS first release, A01 (O755-A01. (EXE), currently available from http://www.dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=R164252

  Second, you will need also the latest version of the BIOS, A22 (O755-A22. (EXE), currently available from http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=2DWTY

  Lastly, you need a USB stick or hard drive which is able to boot the machine in DOS. It is recommended to use the free 'Rufus' tool to create a bootable FreeDOS. Rufus is currently available at https://rufus.akeo.ie/

  In addition, you may need to install jumper on the motherboard service mode; This repair was completed successfully with him helped, although it * might * work without it installed, although this has not been tested.

  First create a FreeDOS using Rufus bootable USB device. When complete, copy the two BIOS A01 (O755-A01. (EXE) and BIOS A22 (O755-A22. (EXE) to the root of the memory stick.

  Insert the memory stick into the computer, and then press F12 for BIOS. Boot from the USB key. Once at the DOS prompt, type:

  O755-A01 - wipeall - wipeclean

  Press on enter and follow the prompts on the screen. After the BIOS has been flashed, the computer must restart. Go into the BIOS and check the options under system boot sequence. The boot sequence should now not only display the name of your hard drive, but will be variable, allowing your computer to start normally. Set up your BIOS Setup to your liking (including date and time setting) and save it then & leave. After the reboot, press F12 again and start once more the USB device.

  Flash the BIOS A22 the standard way by typing O755-A22 pressing on enter. Follow the prompts on the screen. Once the BIOS has been flashed, check the settings of the BIOS again to make sure that the Boot Device menu is always available.

  Once finished, be sure to remove the rider of mode of service (if installed).

  FAQ

  Why it works?

  
  From what I can tell, the previous BIOS flashing tool includes switches that later versions are not. -wipeclean - and wipeall are an integral part of this fix works as they completely erasing all the BIOS settings that are not usually deleted when the BIOS is updated. For some reason, Dell has removed these BIOS update tools options later.

  In addition, the previous BIOS flashing tool actually flashes the BIOS itself DOS rather than rely on the BIOS RAM loading and then Flash with routines in the BIOS of the current system. I have no idea if that makes a difference in the process, but I imagine that it allows more options to pass to the routine of flashing.

  Sorry for the long post, but I hope this helps someone! Having recently put his hands on a couple of these machines and having the same problem, it's incredibly frustrating.

• OptiPlex 755 Mini Tower does not, no outdoor lighting

  I can not get an OptiPlex 755 minitower to light. It ran quite constantly in a desktop environment on a battery backup/surge protector APC until it failed Monday morning. Then, there was little orange light flashing or continuous. When the computer was turned off, he would not come again. Sorry for the blur, but it's an opportunity information. I found a lot of dust inside, but I've seen much worse on computers

  When I push the power button, I get no change: no light in the power button, no diagnostic lights, no noise, no fan movement. When I connect it to power the led "to THE" on the motherboard is provided on a solid yellow/orange for the power supply is to put something.

  Is this likely to be a power supply problem? Is it possible to limit other than buying a replacement POWER supply?

  Thanks for any help,

  Sounds defective to me. Not sure about the thing of trombone. A NH493 replacement costs $ 29.95.

• Card PCI-E graphic for Dell Optiplex 755 SFF

  Hi all

  I have an Optiplex 755 SFF 275W PSU and PCI-E video slim with.  Graphics on this series are awful - video DVD playback cannot without jerking.  I spent a few hours trolling on the web trying to determine which video card will work in the 755.  The general consensus of the 'guaranteed' card is the Radeon HD 2400 PRO.  So, I managed to follow a fact (after trying a 5570 & it not even leave the PC start), had shipped here and installed.  To see that it does not too leave the PC startup.  So typical of Dell to make the PC which are incredibly limited.  What is the point of having a PC capable of running Win 7 (will have 8 GB of DDR2 RAM, has currently of 2 GB and currently has a Dual E6550 - core 2.3 Ghz CPU) when he cannot take a card even modestly spec'd?  This is the last time that I buy Dell.

  Anyway, having spent the mug shot (ah, much better, thank you)-why the this junky 755 will only take the so-called "guaranteed" HD 2400 PRO?  When I try to start it up, it not this stupid pre-start high ramp / down fans, then turns off, try again, then turns off, then on the 3rd go fans just go hard on & stay like that for as long as I care to leave.  If I take the HD 2400 PRO on & put this stupid DVI adapter card in the PCI-E slot, it's all good.

  No changes have been made to the 755 - it's just a standard stock machine.  If for some bizarre reason, all others using the HD 2400 PRO with the 755 SFF tell bald-faced lies (that is, they are not really using a HD 2400 PRO at all), what are the other maps?  I see that the motherboard has "25W" appear next to the slot PCI - E - but the HD 2400 PRO is rated at 25 w max.

  Buy the 755 was supposed to be an inexpensive way to make a living desktop PC.  I don't want to lose more money on cards that don't work.  And the HD 2400 PRO was relatively expensive for such an old map, obsolete (crazy NZD$ 42 - when a 5570 is only NZD$ 65).

  Any help / constructive suggestions appreciated.
