At an i7-2820QM no advantage on workstation running i7-2720QM?

Guys and murder,

I replace my desktop computer with a Sandy Bridge Mac Book Pro 17 or a Sandy Bridge HP Envy 17 3D (if HP ever releases it to the Netherlands).

I have 2 licenses of VMware Workstation 6.5 (Win), I will move to 7 when I bought the laptop.

With Workstation 7 (Windows) in mind, there will be any advantage to get the i7-2820QM instead of the i7-2720QM?

I'll be switching between:

3-4 simultaneous 512 MB Ubuntu Server VM (windowed and reduced) and Aptana Studio into an Ubuntu Desktop VM (full-screen or windowed alternating).

and

1 oracle DB Express with logical server in a VM Ubuntu (with windows and reduced), Oracle Fusion Middleware, Oracle's Tuxedo and Oracle JDeveloper in a Ubuntu Desktop VM (full-screen or windowed alternating).

And I'll also have IBM Access Client running on the host computer with up to 6 terminal/printer sessions open at the same time (negligible impact).

When the VMS works do not, I will be modeling in cinema 4 D first Sketch & Toon, drawing in Illustrator CS4 and Photoshop CS4, some Unity free 3D, navigation, watch the movie (3D) occasional strange, not HARD drive and not to make any game.

Looking at the specifications of Intel, except the price and comparing the differences between the two, illustrated below, the only significant difference is with the "Intel® Smart Cache and all the remaining specifications do not below are identical."  The obvious differences and expected, clock speed, frequency Turbo Max and Bus Ratio/base, are insignificant when you compare two processors when there is only a difference of 0.1 GHZ between the two.

Number of processor i7-2820QM Number of processor i7-2720QM
Clock speed 2.3 GHz Clock speed 2.2 GHz
Max Turbo frequency 3.4 GHz Max Turbo frequency 3.3 GHz
Intel® Smart Cache 8 MB Intel® Smart Cache 6 MB
Bus/core ratio 23 Bus/core ratio 22

The real question should therefore be ready to pay the price difference to win such a marginal increase in clock speed, the Turbo Max frequency and the Bus/basic Ratio for the 2 extra MB of Intel® Smart Cache.

I doubt really would be able to perceive a difference of 0.1 GHZ to which however 2 MB of Intel® Smart Cache extra is a significant speed and for a power user this can make a difference but let face it goes down the price so I say buy as much computer you can afford everything in getting system that has all the other features need/want.

  • 9 workstation running Windows 10 Pro?

    Before I commit to upgrading my computer (i.e. the physical host machine) to 10 (from Win7) Windows, please someone can tell me if VMware Workstation version 9 on it survive the upgrade?

    From the Win10 updated, I did it on some other machines some service applications non-Microsoft restarts automatically after the upgrade.

    However, as long as a reinstallation of the VMware on Win 10 9, if necessary, gets me back to operational status after that the level Win10 and I do not lose the virtual machines then I'll go ahead.  But for-warned is for arm so all information would be welcome.

    Thank you!

    Pete

    Without even trying, I would say 'NO' because there are problems with 10 workstations running Windows 10.

    You normally won't loose virtual machine if you select upgrade instead of a new installation of Windows 10, but to actually use these virtual machines, you must upgrade to VMware Workstation.

  • I just bought a HP Win 7 (unfortunately) workstation running. My previous computer ran HP XP. Windows will not let me install my fonts.

    Don't get me wrong, the HP workstation is great, it's Windows, I just can't stand.

    I tried to double click on the fonts to install and Windows returns an error message. I tried dragging the fonts in Windows 7 fonts folder and it gives me an error message. I downloaded AFM to PFM because Windows says I need the PFM files, but when I run the AFM to PFM, it returns the message that the PFM files are already there.

    I bought a laptop Sony a couple of years ago with Vista and fell on this problem. I despised Vista so I sold the Sony and remained with XP on my HP Workstation. In fact, I was so p - o'ed on Vista, I went out and bought a Mac Pro and Mac Book Pro, as I intend to dump Windows altogether. Unfortunately, the vast majority of my work required of Windows programs.

    Given that, I decided to go for the new HP workstation because I had heard horror stories less on Win 7. I was then going to sell both of my Macs.

    Unfortunately, it was a BIG mistake because now I'm stuck with a work station $3,400 that I can't use to work on my documents InDesign, Illustrator and Word that have all of the fonts I was running XP (and which run WITHOUT problem on my Mac).

    It is a problem of Windows, and when I tried to contact MS supports, I was directed to HP since Win 7 is pre-installed on my workstation.

    I just got the phone with HP Technology Support and they say they can't help because even if it IS a WINDOWS PROBLEM, they do not support software related issues.

    I even tried to copy the font files to the Directory Windows on my old PC, nothing helps.

    I'm willing to put this thing on eBay so I can't empty MS FOR GOOD!

    Any help would be LARGELY APPRECIATED1

    Hi AndrewHerman,

    The steps in this thread has helped other users who have also struggled to install fonts in Windows 7. Let us know if that helps.

  • Workstation running inside Parallels 9 10

    Hello

    I need to run workstation 10 inside Parallels for Mac 9.

    I was able to create the virtual machine, but when I turn on the virtual machine, I get the following workstation error message:

    "You run VMware Workstation through a hypervisor incompatible. "You can't power on a Windows virtual machine so that the hypervisor is disabled".

    Since I can't run 10 Workstation directly on my MacBook, is there any workaround solution you can suggest?

  • An image of vmware workstation running on ESXi 5.1 9

    Hello

    I have a vmware image of Win Server 2008 I am able to run on a vmplayer running the Ubuntu 64 bit PC. According to vmplayer, it's a workstation image 9.

    I also had vm workstation 8 32-bit on a 32-bit PC Win7, but I am unable to run the image here, probably because the host is only 32-bit.

    I now run the image on a 64-bit server running ESXi 5.1. I know there are steps to export an image workstation to ESXi via my computer, but my workstation allows 32-bit vm convert a 64-bit image? What are my options?

    Thank you!

    It is less the host operating system that is important, it is the CPU that you use and available BIOS options (e.g. "VT - x" for Intel processors)

    ESXi does not support the format of sparse virtual disk Workstation uses by default, so you can use VMware Converter to convert/transfer the image of the workstation to ESXi.

  • Guests of workstation running on VI3 infrastructure - issues?

    So far, we rotated only server O/S of our infrastructure VI3 (no treatment intense or interactive graphic type).  I wonder if I will support a few dozen invited workstation in this same environment. These guests could be interactive and graphic oriented. Is this a bad idea? Other people mix invited os server and workstation hosts in a single environment. We will be at a time looking for VDI and other desktop-oriented solutions in the near future. Optimization recommendations which should be made to these guests would be greatly appreciated as well. Thank you

    We have about 8000 OS VM desktop computer and have seen great returns.  Most of them perform in their own instance of vCenter, but we have a handful that are running in the same vCenter as our server VM.  We created a new cluster for the Office of VM.

  • VMware Workstation running without the GUI

    I used to use VMware Server and configured to start some VM, I need on-site at startup. I went to the workstation to work with our ESX VM, so now I wonder if there is an easy way to get a similar behavior.

    There is no a lot of information about this in the manual, I tried running ' / usr/bin/vmware - blah.vmx x ' when when I connect, but the graphical interface starts too. If I can remove the GUI and I have just the tray icon, I'd be a happy man.

    Once my session X crashed and the VM kept working well, so I guess that there is a process that is actually running the virtual machine independent of the GUI somewhere can I drill to get the virtual machine started?

    N ° workstation is designed for interactive virtual machines.  6.x and newer, the ability was added to maintain a virtual machine running in the background AFTER it was launched upward - however the GUI should be started to start/run prompt, AND user must stay connected (i.e. the virtual computer is running as a user process).  If you want to run virtual machines under services, using VMware Server.

  • 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.

    Who remembers to do it manually?

  • Collect and display data from several workstations

    Currently, the data in the CSV format locally on several workstations running Labview and the format of the recorded data is the same for each workstation. Data are recorded roughly every 2 minutes at each station and at different times.

    Computers of these stations are connected network but no saves a copy of their files CSV to the server that I know is not ideal, but a part of memory original.  What is now there that a computer on the network brings together these data by workstations and then the poster showing trends in workstations etc. in graphic format and possibly Excel.

    What I'm looking for is some advice on the best way forward.

    I looked at shared variables as a possible solution, but it is work stations send their respective data to the 'central' PC or this PC "questions" workstations that seems inefficient.

    Another thought was using Active X workstations to write in an Excel file running on the "central" PC

    Finally thought that workstations have record their findings to a server and then 'central' PC to access that data, it brings together and then displays the results combined.

    There are several things that remains to be clarified.

    • All LabVIEW programs, individual data record data in the same format and the same number of data points?
    • Record all programs of LabVIEW at exactly the samerate?
    • Are all data on a be saved in a single file of the Machine, or each reading (at intervals of 2 minutes) in a separate file?
    • You are trying to combine data from different machines such that it is collected or after the entire collection was done, and all files have been written?
    • Another that the timestamp of the data file, is there a "time stamp" in (all) the individual data files?
    • If you assume that the data of different machines are more synchronized, you have in mind a way to combine the different readings of the time?  What happens if they are sufficiently different that, say, the Machine has 20 readings more (because it started much earlier) than other PCs?
    • If the machines are not saving at the same rate, how will handle you that?

    A single method, you might consider is to write a program that works on any network connected PC, including a no participate in the recording of data.  For simplicity, assume that each machine "participatant" starts at around the same time, saves exactly at the same rate, written a single data file and has already closed.  If the program "Combining" knows where all data files (because he knows the name of each machine and the location of the file on each machine), it can open all the files, collect all the data and treat it but want to (including a 'combined Excel workbook"writing with a spreadsheet separate for each PC, or combining them all on one sheet).  Just decide what you want to do in the context of the issues raised above.

  • External client access VMware Workstation shared 11 VM?

    Hello world

    I have a small problem that we have a VMware workstation installed on my PC to 10 windows and I would allow a few colleagues access to the virtual machines shared on this topic.

    I enabled the shared virtual machine settings, and I can confirm that I can connect from another post on my local network.

    However, I can't seem to connect to the shared virtual machines from outside my network. I DynDNS and handed over port 443 to the Windows box with installed Workstation (192.168.2.10).

    I even tried changing ports internally using the shared virtual machine parameters.

    Also tried, is to have a different external port one internally (7000 ext sent to 443)

    Adding to this I tried the IP of my router (to rule out DDNS) - in regard to this, I can connect directly to the virtual machine via DDNS passed to image.

    The Windows Firewall is disabled on the host of the workstation.

    Then... Please this is; Is this really possible? Before that I continue to invest in any time in it.

    And... I tried to get that I promise you!

    Kudos to everyone for any help

    Hi SpoonRacer,

    Welcome to the community of workstation! Of course, this scenario is possible. Sharing of the VM has no difference with other standard network on the IP layer services.

    I think that General measures to be implemented are:

    1. Get the accessible external IP address of your private network
    2. Map the TCP 443 port to the external IP address on port TCP 443 of the Windows box workstation running by the DNAT
    3. Allow inbound network traffic on port TCP 443 on Windows machine running Workstation
    4. (Optional) Configure DynDNS point your domain name to the external IP address of your private network

    For example:

    1. Get the external IP address: 216.58.216.164
    2. Map 216.58.216.164:443 to 192.168.2.10:443 by the DNAT
    3. Open the TCP 443 port on host 192.168.2.10 (now you should be able to access your shared virtual machines using 216.58.216.164 for outside networks)
    4. (Optional) Configure ws.spoonracerdomain.org resolves to 216.58.216.164 (now, you should be able to access your shared virtual machines using ws.spoonracerdomain.org for outside networks)

    However, these steps are not very easy to implement due to some possible limitations of your private network:

    • If your private network is at home, the external IP address and it is very accessible from outside of the network depends on your ISP (internet service provider). I know, some ISP does not allow the public IP address used by individual users accessible via the public network. Some ISPS even not you assigned a public IP, other users and you share a single public IP, in this case, you would not be able to apply step 2.
    • If your private network is to your business, and you're not network administrator for your company, you would not be able to apply step 2.

    Anyway, you can try to open a Web site on the Windows machine running Workstation to the outside network. If successful, then the service share of VM can be done the same way (just change the port 80 of the site to 443 folder).

    Kind regards

  • 11 - Win7 Guest Host Win8.1 - SLOW comments PRE-LAUNCH workstation

    Hello

    I'm new to vmware and used to work with VirtualBox.Guest on VirtualBox boot immediately when started.

    My host is running on a core AMD FX-8350 8 4.2 Ghz with 32 GB of ram and VDI are stored on a Samsung 850 PRO SSD.

    Whenever I start a guest with Win7, I get a black screen for couples of minutes THEN prompt boots at a normal pace.

    No idea what vmware did to 'prepare' the boot?

    (I read that vmware renaming "* debug*.exe" makes it faster.) Which I did and did not notice that many improvements)

    But if the guess is paused, then restarted - it's quick to get back running as expected.

    Thank you

    There is something fishy with Workstation 11 or 11.1 virtual hardware...

    Bottom line - 11.1 workstation running invited Workstation 10 hardware compatibility seems to fix the problem.
