Dell Optiplex GX 280 Small Mini Tower Processor Upgrade

This question is not answered

I currently have a Dell OptiPlex GX280 with an Intel Pentium 4 520 2.8GHz and I’m going to upgrade it to the Intel Pentium 4 670 3.8 GHz. Yes I know I have to upgrade it to a Dell Power Supply and Fan. But I just wanted to know if it would work without any incompatible errors. Thanks.

  • You would have to get the Copper High performance heatsink or it would shut down due to overheating.

    I have a suspicion that 3.2 Ghz is max and over that speed it will Halt with Incompatible processor message.

    Be aware that there are 5 documented versions of the GX280, each of which has its own technical specifications, unique CPU fans, PSUs, etc. It's worth your time to be sure of the one you have and what its specs are before attempting an upgrade.

    After reading about the power consumption of the 3,8Ghz 570J, Dell's tech docs indicate that a 305W PSU is standard equipment in the Small Mini Tower (SMT) for processors running faster than 3.2Ghz.

    BIOS to A08  GX280A08.EXE should be installed BEFORE attempting to install a newer processor.

    I would recommend an Dimension 8400 350W Dell-branded PSU

    You should check

    http://processorfinder.intel.com/Default.aspx

    What is the S Spec of the current cpu?

    What is the S SPec of the other CPU?

    What is the CPUID of the current cpu?

    What is the CPUID of the other cpu?

    There is no psychic reading of microcode that goes on here. What do the latest bios release notes say?

    What does intel say about the chipset and fsb and packaging?

    If you don't know this information its likely you don't have an idea how to handle the processors either and or will damage the motherboard and the processor.

     You may also find that an Optiplex GX620, GX745, GX755 Mini tower is a better upgrade and COSTS less because it already comes with a faster Processor and 305W power supply.

    I do not work for Dell. I too am a user.

    The forum is primarily user to user, with Dell employees moderating.

  • ok will this Power supply Be Compatible with the OptiPlex GX280 because I heard that only PSU’s directly from Dell will only work in dell computers. accessories.dell.com/.../productdetail.aspx

    or do i have to buy a Dimension 8400 350W Power Supply ?
