    The Operating Systems aren't corrupt because if I use a different CPU everything works.

    Here's what I get with the E5200 and booting Linux:



    I put the MCE codes through mcelog --ascii and all it says is:

    CPU 1: Machine Check Exception: 5 Bank 0: b200004000000800
    CPU 1: Machine Check Exception: 5 Bank 5: b200121020080400
    CPU 0: Machine Check Exception: 4 Bank 5: b200121014040400
    CPU 0: Machine Check Exception: 4 Bank 0: b200004000000800
    HARDWARE ERROR. This is *NOT* a software problem!
    Please contact your hardware vendor

    Trying to boot Windows 7 gives me a BSOD and WinXP SP3 just restarts before it's finished loading.

    What do you think? Faulty CPU? or weirdo Rev 1.0 board..?

    It suggest memory error, try running memtest86+, if you get errors or it freez try with one of the other processors.
    Check The E5200 pins, if they clean and intact.
    I lean towards the CPU.

    The memory is ok, but I managed to test the E5200 in a friends motherboard with different RAM, and it still fails with Machine Check Exceptions, so I guess it's got to be a faulty CPU. Time for a refund or replacement.

    Thanks for all your replies and help. Really good forum you've got here. :)

    Oh, I forgot, here's the full decode with mcelog --cpu core2 --ascii

    Contacted Gigabyte and they said do a fresh install of the OS, hmm, don't think that'll work because even Linux LiveCDs crash on boot up, except for a really old one from 2005 which actually worked (once) but detected the CPU as a Pentium 3. So I've sent Gigabyte the MCE decode log, waiting for a reply ;) Got a refund and get to keep the chip, so might be worth experimenting a bit more, maybe..

    Is the CPU too old to be RMAd?

    It's not boxed or with a warranty so I don't think I can RMA it. I got a refund so I'll just keep it as a curiosity.

    Why is it suspected to be manufactured by company other than intel? Won't cost anything to try.

    Defective CPU, my E4500 that was a golden chip with it's 1.200v VID would do 3GHz at that stock volts and 3.5GHz at 1.45v, most can't even POST 3GHz @ 1.28v. On x86 OSes it was fine, on x64 at 3.1GHz and further it would love to bluescreen with machine check exception, after some time it was determined the "extra" 32 bits that are only in use on a x64 OS, were defective and the BSOD kept happening at the same spot every time, numbers in brackets always the same yes temps were fine volts were clearly fine it was a golden chip.

    Nice to hear you were able to test the CPU on another board and found it to be the cause, sorry to hear it was the CPU though but at least you got a refund and can keep the chip too! :)
