Optiplex 760

This question is not answered

Hello,

I have a Dell Optiplex 760 with a E5200 CPU. Does my system board support any upgrade in CPU? I was thinking about a core2quad.

thanks

    The Optiplex 760 MT was built with two different motherboards.

    T674K motherboard does not support Core 2 Quad CPUs, only Core 2 Duo CPUs.
     
    U562N motherboards support both Core 2 Quad and Core 2 Duo CPUs.

    Which version is installed in the your Optiplex 760 MT?

    If the computer was shipped with a Core 2 Duo CPU, then the motherboard is usually the T674K version.

    The following CPUs are supported by the T674K version:

    E7400, 2.8GHz, 3MB, WFD, R0, (With VT)
    E7500, 2.93GHz, 3MB, WFD, R0, (With VT)
    Wolfdale Dual Core E7600, 3.06GHz, 3MB, 65W, R0, (With VT)
    Wolfdale Dual Core E8400, 3.0GHz, 6MB, 65W, E0, 1333FSB
    Wolfdale Dual Core E8500, 3.16GHz, 6MB, 65W, E0, 1333FSB
    Wolfdale Processor E8600, 3.33GHz

    Prior to installing the processor, check that you have the latest BIOS version installed.

  • I cant see the number on the board anywere. This is what a system test reports

    Board: Dell Inc. 0M858N A01

    Serial Number: ..CN1374096G03W3.

    Bus Clock: 800 megahertz

    BIOS: Dell Inc. A13 08/04/2011

  • If my research is correct my board will support quad core. What quad core CPU can I use? Can I use q6600?
  • jpro68

    The following Core 2 Quad processors are supported by the Optiplex 760.

    Q9550

    Q9650

    Q9400

    Q8300

    Q8200

    Prior to installing the processor, check that you have the latest BIOS version installed.

  • Hi,

    Just to confirm, are we saying that only one of the 2 used motherboards support our E5200 chip? and that motherboard is the one that supports Core2Quad?

    I was stupid and bought a Q9400 yesterday because on the intel site it says the q43/q45 supports the core2quad and evidence on dell said similar.

    I would be devastated if the chip didnt work :(

    It is not the chipset, it is the number of voltage regulator IC's the motherboard has.  The T674K is the cheap motherboard version and has less voltage regulator IC's.

    To quote my previous post:

    T674K motherboard does not support Core 2 Quad CPUs, only Core 2 Duo CPUs.
     
    U562N motherboards support both Core 2 Quad and Core 2 Duo CPUs.

    Which version is installed in the your Optiplex 760 MT?

    If the computer was shipped with a Core 2 Duo CPU and not the Core 2 Quad, then the motherboard is usually the T674K version.

  • Thanks for the response geordie.

    See this is the confusion, using CPU-Z, as the lad above says; we have the motherboard "0M858N". I've checked the inside of the computer and there is nothing which tells you whether its any of the motherboards you mention.

    Googling that number brings you a part number, with no specs and dell site too does not even register it in any search too.

    Another confusion is, its the SFF that I have not the mini tower. So the incoming power is a lot less than the mini tower @235watts compared to the 305.

  • would be interested in what you've done mate, sounds like youve got at SFF and trying to do the same as me. except, i need hardware virtualisation support.

  • that was to jpro68

    The discussion in this thread is about the Mini Tower version, not the SFF.

    The 0M858N motherboard should support Core 2 Quad CPU's, but the OptiPlex 760 SFF probably will not support quads, as the 235w power supply is too small and cannot be upgraded, as it's a Dell proprietary unit, due to it's shape and size.

  • oh man. I was hoping this wasn't the case. i can only try it and report back my findings. Just bought a Q9400 for it and was hoping to run a virtualized sharepoint farm off it for development :(

    I dont think there is a thread for the Optiplex 760 SFF is there? Google brings back this page if you search for optiplex 760 quad core upgrade.

    If you want to upgrade, a SFF system is the wrong one to buy, you need to purchase at the minimum, a Mini Tower computer.

    There is the following post on upgrading the CPU of the OptiPlex 760 SFF:

     http://en.community.dell.com/support-forums/desktop/f/3514/p/19470467/20203289.aspx#20203289

    Personally, as you have already purchased the Q9400, I would install it and see if the system boots correctly and runs without overheating.

    Before installing the processor, remember to upgrade the BIOS to the latest version, because with version A11 Updated Intel Processor's microcode was added.
