XP_64 very unstable here...ram problem?

Discussion in 'Windows 64 Bit' started by NM8R_jsimpson, Apr 26, 2006.

  1. ASUS K8N-DL motherboard, two AMD 275 "Italy" dual core procs, six 1G sticks
    of Ultra ECC reg ram. Updated BIOS right off the bat, all procs now properly
    recognized and all ram is seen by bios.

    I keep getting "machine check" errors in XP64, and the system overall is
    VERY unstable.....lockups, reboots, etc.

    There is a memory setting in bios that I need to disable to stop the machine
    check errors....sometimes it won't finish booting unless disabled. It gets
    as far as the ACPI table and reboots.

    Considering yanking half the ram out, reformatting and installing 32 bit XP!
    Any help is greatly appreciated!

  2. Machine check errors are almost always hardware issues. I'd start by
    limiting the total amount of RAM to one stick for each proc, and test the
    heck out of the RAM. (see my blog for some choices on RAM testers.) Then, if
    that's good, add in additional RAM and test again, etc.

  3. Isn't it true, reg. RAM comes in pairs? Suppose it is not fitted
    accordingly, is there a simple way to see by the serial numbers which sticks
    belong together?

    Not suggesting it's a propable cause - "leave no stone untouched", rather.
    No, I am getting suspicious over that remark about the BIOS. If this
    behavior is triggered by the BIOS being configured for reg. RAM and that it
    stops if setting it for standard RAM, then that could very well be the ' IT

  4. Some come in pairs, some come single, and different mobos have different
    requirements. It's a pain that way. I'm pretty sure the ASUS boards can use
    single sticks or matched pairs, depending on the particular amount of memory
    you're installing.
