  1. Pentium D, maybe a core 2 duo, but I doubt the bios would support it.

    That is a really old computer. Like ten years ago DDR 533 old. You may need to upgrade to do... anything with that.
  2. while there may be some upgrade options, you'll be going from really, really slow to also really, really slow. It would be like trading a car that goes 4mph for one that goes 5mph. While one is technically faster, both are too slow to be useful.
  3. the only way you're gonna upgrade a socket 775 CPU is finding a used/refurbished one off ebay for $70+. not worth it.
    save up for a new machine.

    I was just wondering if you could maybe tell me if and how I could upgrade my bios. Thanks :)!
  5. Dell may have the last BIOS for download and reflash. You will need your service tag and the serial number.

  6. Unfortunately, Pentium D would not work here, only single core, I think the Pentium D needs the 945 chipset which is in the 520/620 systems. The 280 is almost identical to the 520/620 as far as parts go, but it has a 915 chipset. Also, You can only use Intel 5xx series CPUs.
    Not all LGA775 CPUs work in GX280. For example, Pentium D and Intel Core 2 Duo are LGA775 but they will refuse to work in the GX280 (might even damage components, don't try those). This is the list of processors, validated by Dell to work in your GX280, note that for CPU 3.4 GHz and above you need a 304 watt Dell power supply:
    Prescott P4 Kit, 520, 2.8Ghz, 800FSB, 1MB
    Prescott P4 64bit Kit, 521, 2.8Ghz, 800FSB, 1MB
    Prescott P4 Kit, 530, 3.0Ghz, 800FSB, 1MB
    Prescott P4 64bit Kit, 541, 3.2Ghz, 800FSB, 1MB
    Prescott P4 Kit, 540, 3.2Ghz, 800FSB, 1MB
    Prescott P4 Kit, 550, 3.4Ghz, 800FSB, 1MB
    Prescott P4 Kit, 550, 3.4Ghz, 800FSB, 1MB
    Prescott P4 Kit, 560, 3.6Ghz, 800FSB, 1MB
    Prescott P4 Kit, 570, 3.8Ghz, 800FSB, 1MB
    Those are the only options according to official Dell look here for proof http://en.community.dell.com/support-forums/desktop/f/3514/p/19266896/19458879.aspx#19458879 look for Chris post.
    So as someone noted above, there is nothing serious you can do here, but to get newer PC or build your own.
  7. You easiest upgrade might be to find another board and cpu combo from a system that used the same tower design. Otherwise, you are dead in the water.
  8. Those series Dell cases where proprietary. If memory serves the PCI bus was detached from the motherboard.

    You will need an new case, board … everything.

    Kisianik is correct, I shot from the hip, but qualified it saying I didn't thing it was supported. Its not.
