    Dear Sirs,
    I recently put together a system that consists of:

    Motherboard - Soyo K7VTA VIA KT133 chipset 200 FSB
    CPU - AMD Athlon Thunderbird 900 Mhz
    Memory - 1 Micron 256 MB, PC133
    Hard Drive - IBM 40 GB ATA 66 7200 RPM
    OS - Windows 2000 SP 2
    Video - Gigabyte Geoforce2 MX400 64MB

    This system has been running fine and without incident until I recently purchased an addition memory module. The memory module is identified on the chips as, Siemens HYB39S256400T-8(B). It was advertised as 512 MB Unregistered, PC133. I installed the memory into the next available DIMM socket (3 onboard). When I rebooted the computer several things happened.

    1.) The PC booted through BIOS where the memory was tested and recognized (786,432 total memory) them memory and began to load Windows and then suddenly rebooted. This occured over and over.
    2.) After booting into BIOS setup (Memory was recognized in BIOS) I exited and when the machine rebooted I received a STOP error.
    STOP error = The ACPI BIOS in this system is not fully compliant with the ACPI specification. 0x000000A5, 0X00000011, 0X00000007, 0XEB8680C0, 0X0100000C

    I then removed the new memory module and the machine booted normally.

    Can you please offer me some suggestions.

    Thank You,
    Kelly Rudnick

    What happens if you put just the new module in? Any problems (could be a bad module)? If not:
    Do you know if the new memory is ECC or non-ECC? What about the original memory?
    Also, do you know if the original memory is also unregistered/unbuffered as opposed to registered/buffered?
    If they are of different types, they may not play well together.

    If I remember right the installed memory is non-ecc and unregistered. I searched the micron product number (48LC16MBA2-75B) and it doesn’t really indicate. I did try to boot the PC with the new (512MB) module and it failed to start. It didn’t boot just continued to beep a single beep. I reseated the memory a couple times with the same result. Then reinstalled the original and it was fine.
