  1. I just did my 300th or so board
    dual xeon 2.8 with new copper heat sinks
    on first post 1 board just beeps long for about 8 beeps
    no video
    2nd board 1 long continous beep overheat light comes on
    by the way 1 cpu at a time to test
    with 1 cpu board stays on
    but the other cpu 1 beep and shuts off
    can't send back the cpu's could it be something else not
    these do this as soon as powered on

    This sounds like bad motherboards, not CPU's or memory

    hi sam,

    you should be able to rule out overheating by removing > cleaning > re-applying compound > and re-installing your heatsink(s). do you have a physical temp probe (not software) that you could use to check your temps?

    anything is possible, but it seems unlikely that 2 boards would both be bad.

    I tried looking up your beep code but could not find anything for "8 long beeps". i don't know what BIOS your motherboard uses, but here is a good list of beep codes from all the major BIOS brands, maybe one of those codes matches the error you're receiving?

    good luck :wave:

    looks like buying more xeons this week
    just bought more memory just in case
    client getting antsy

    new memory came in
    diff types of same memory who whould'a known
    pc2100 ecc reg'd are not all the same it seems
    so now the boards are tested with a older xeon from ebay they post
    the 2 xeon's bought from dealer are the bad items and one goofy stick of smart memory
    I thought smart was reliable "oh well'
    finally finished main parts scraped the whole lower end xeons and went for 3ghz 64 bit 800mhz fsb
