RAM question

  1. Hi i am looking to install some new RAM in a computer. It will support two 512 MB cards to make 1GB. It takes SD-RAM and DDR1 RAM cards. I have a question about the memory bus.

    my SD-RAM slots in my motherboard can support up to 133MHz and the DDR up to 266 MHz.
    If i brought a card that had higher than that, say 400MHz will it still work?
    will it degrade itself to 266MHz (i am buyin DDR1)

    I would appreciate any help.

    RAM will downclock itself to the prevailing buss speed. Just putting faster RAM in won't speed up the machine and might cause problems. You should upgrade with the same type of RAM as is already installed.

    This thread is a "must read",(literally). It should begin to answer your questions;

    also-another question. The current card in my machine is PC2100.
    If say, i brought a pc3200 card, would it downclock itself to the standard of the max my motherboard can support. (i am not sure if it can support 3200 or not.) (it may)!

    Your mobo should support it. And yes, the pc3200 will downclock itself to run at 2100 speed.
