Ram affecting overclock

i was wondering how ram effects your overclock of cpu. If i get lets say 2100 ram will it allow me to overclock my cpu more then say 1600 ram, and to what degree?

-Thanks for any and all help

  1. Your RAM can limit your overclocking but so can your motherboard. Depending on which components you have your RAM may or may not be the limiting factor.

    Taking your example of 2100 vs 1600:
    ->using a 2x multiplier would mean that you could reach a FSB of 800 with the 1600ram or 1050 with 2100ram

    Now it's pretty unlikely that you'll reach such high FSB speeds so it's probably better to just do some research to see which ram will be better suited for your needs.

    Also I'm a bit tired right now so the math may be a little wrong
  2. It all depends on the motherboards compatiability with which RAM is better suited to your needs..Say you Have a board that handles 2100 MHz RAM well if your OCing this extra RAM speed stability allows for much higher OC's with stability...

    Example:

    Stock Speeds

    RAM 2100 MHz
    CPU 3.2 GHz
    CPU Multiplier x16
    FSB 200 MHz

    OC ed

    RAM 1600 MHz OC 2000 MHz
    CPU 4.0 GHz
    CPU Multi. : x16
    FSB: 250 MHz

    This is where the extra RAM speed stability is required under an OC scenario...You see by setting the RAM which is rated to 2100 MHz to 1600 MHz in BIOS then setting the FSB clock to 250 your RAM is then at 2000 MHz..Which is a 25% OC...

    @akxpckwb---> Where did you get that math from? 800 MHz FSB get real, that would equal on the above setup with a CPU multi. of x16 would be 12.8 GHz...You need to learn your BIOS and computer a little better.
  3. @lowjack989
    Yes I know it's impossible to reach such high FSB speeds. Didn't take into account the CPU multiplier. Thought it would make things harder for OP.
