GX280 incompitable processor detected

  • I would like to ask help of you about the GX280

    I installed a new processor which is P4 3.6 but it showed Alert! incompitable processor detected.
    System Helted !


    I went to the dell.com and I downloaded the last bios which is A05 instead of the A04 which was installed


    any help please
  • aladdin_nackchabandi,

    Thanks for using the Dell Community Forum.

    Was this an Intel P4 that you installed?

  • Yes sir it is an Intel Pentium 4 the one without pins that is compatible with the motherboard that came with the dell system

    Please provide me with the solution ASAP I have five system need to be delivered before next Monday

  • There was a thread entitled "Higest Configuration for DELL Gx280 Tower" which now appears to be dead. It stated that the P4 3.4 (presumably a P4 550) was compatible. However I got the same message when I plugged on in last night.

    Any help out there? Is there a bios or chipset update that will fix this?

  • For what it's worth, I decided to test the upper end of the P4 5x0 family in my GX280

    First I consulted docs on Intel to identify my processor using their Processor Identification Utility.

    http://www.intel.com/support/processors/tools/piu/sb/cs-014921.htm

    Then I consulted docs from support.dell.com to verify power requirements on the GX280.

    http://support.dell.com/support/edocs/systems/opgx280/en/ug/specs02.htm

    My version is the Small Mini Tower (SMT). According to the technical specifications listed there , my GX280 SMT requires a 250W Power Supply if running a processor up to 3.2Ghz, but 305W if you're running faster than 3.4Ghz. By the way, the heat dissipation of the GX280 is striking:  SMT computer with processor speeds of 3.4 GHz or higher: 1041 BTU/hr, Vs. GX280 small form-factor computer: 546 BTU/hr

    First I upgraded my power supply and got a Dell-branded 350W. I then upgraded my SMT to the A08 BIOS and the downloaded and updated to the latest version of the Intel chipset drivers. I found a reputable dealer and bought the Intel P4 570J (3.8Ghz) processor. The 570J has the same cache and supported features of my current 2.8 Ghz processor: no support for virtualization or 64-bit OSes, same cache, same core stepping, same package type, support for HyperThreading and Execute Disable bit. There's nothing obvious in the Intel documentation that would indicate that the processor is incompatible.So I installed.

    But no luck-- I got the same message-- system halted.

    With most applications that I run, my GX280 does not seem to be processor bound, so it was pure greed for speed that drove me to attempt the upgrade. Based on what I've seen on Tom's hardware,  it looks like a 3.8Ghz will work, but not the 570J version.

    Considering its age and limitations, this is a very solid, upgradable box.

     

  • UPDATE!

    Again, rely on the Intel Processor Identification Utility to positively identify your CPU. Mine was Intel Pentium 4 CPU 520.  Check the CPUID Data tab and note the value for Platform Compatibility Guide. Mine said 04A. When considering a replacement or upgrade for your CPU, be sure that the replacement processor uses the same PCG code.

    I purchased and successfully installed a processor with the same PCG:  Intel Pentium 4 650 (3.4Gz, 800Mhz, 2MB cache) . The cost was relatively inexpensive ($40)  and the improvement is especially noticeable when I'm  running video-intensive apps and websites. I also now have 64-bit OS compatibility-- the 520 processor did not.

    Beware: there are faster processors in the P4 family. As I mentioned in my previous post, I got greedy and bought a 570J (3.8Ghz, 1MB cache) that did not work-- wrong PCG code. There is a spec for an Intel 662 (3.6Ghz 2MB cache) with the same PCG. But after searching online for a month or so, I gave up and got the 650. If you run servers and multitask a lot, you know that cache is king; if you're given a choice between comparable processors, get the one with more L2 cache. You won't regret it.

  • i just recently bought a pentium 4 550 for my gx280 and it just gives me the system halted but i dont understand y u listed it under acceptable? is there anything that i can do?

  • Jiminey

    Prior to installing the processor, did you update the BIOS to Version A08, with Version A07, added support for newer processors was added.

  • Yes, i did upgrade to the a08 bios and i tried all the old bios too and i will list all other things that i did...

    bought me and antec 550 basiq power supply "good name right?" should be efficient enough to keep it running right?

    8400gs nvidia

    1gb pc3200

    120hd ide

    40gb sata

    and low and behold the old pentium 4 530 3.0ghz then bought the pentium 4 550 3.4ghz  after reading all the succes stories.

    but i found out i was lied to  =(  so plz help....

  • Sorry I am late to the thread, but what was the processor ID for the working 530, and for the 550 that did not work? I'll dig a little and see what I can turn up. In each processor family, there are compatible and incompatible siblings: there may be 4 or more 530 processors with different PCGs or other unique attributes that make them incompatible.  Sorry yours was a gutter ball.

    Hi,

    I am playing around with my GX280DT (DCNE) and I just installed:

    Intel® Pentium® 4 Processor 571 (1M Cache, 3.80 GHz, 800 MHz FSB) SL7P2 running A08 Bios, Win Vista 32bit on a 64bit CPU, lol.

    Running fine lot zippier now, I'm going all the way to a 670 with this machine I'll let you know.

    I am going to try a 2M CPU next: Intel Pentium 4 P4 670 3.8GHZ LGA 775 2M 800M SL7Z3 SL8PY

    Muahahhaha!

    P.S. I have had Win 7 x64 on it and found all drivers ran ok, but I didnt like not having all 4GB of my RAM.

  • P.S.S She only likes the 64bit video cards of the PCI express 2.0 x16 kind.

    I tryed putting in a B276 that is 128bit, she didnt like that at all.

    Still playing around with GPU's. I have a Radeon HD 1GB 4550, I am planning on putting a GT 520 2GB inside her, but I might find another Radeon HD with 2GB this time.

    Did I mention I have a SFX 450Watt PSU inside running everything perfectly stable.
