    I bought a DDR mobo and some Crucial pc2100 memory a few months ago. After swapping everything out I noticed my mobo reads it as pc1600. I checked the memory it is indeed pc2100. After looking in bios I didn't see anything that I could change so it would recognize my memory as pc2100. Asus has just issued new bios revision which I will update tonight or tomorrow. Since there was a deal I ordered a second stick of 256mb pc2100 from Crucial and it will be here tomorrow. Has anyone heard of this problem?
    My system specs
    Asus A7M266 mobo
    Crucial 256mb pc2100 ram, second stick on the way
    Athlon T-bird 750Mhz 200fsb
    Windows Me

    On that board, you cannot run the FSB and the memory bus at different speeds. Therefore since you are running your FSB at 100MHz, your ram will also be running at 100 MHz. That is why it is showing up as pc1600.
    You will either have to increase your FSB to 133Mhz (ie. 266) or live with running your ram at pc1600.

    I guess I'll have to upgrade my cpu to to one with a 266 FSB in order to take advantage of pc2100. Thanks, Jesse.

    The FSB is Front-Side-Bus, which is based on your motherboard.
