More about what mean
  1. I don't have much experience with you AMD system, I assume, But from what I have heard, that is closer to the timings required for faster performance.

    Try everything...

    Do not regret what you have not yet done!!!
  2. Well the depends, obvisuly your 3-3-3-8 timings are slightly faster than the 2.5-4-4-11. Do you already have your RAM slightly overclocked to match your 210 FSB?

    Generally slowing your RAM timings down a little will allow you to overclock the RAM farther. However with those timings you were given it isn't going to be noticeably slower.

    If your RAM is already overclocked to match your FSB, I would leave it, if you want to overclock your CPU more, you may have to switch to those timings.

    Of course you could always try them out, and see what happens, worse thing that could happen, is that you have to change them back.

  3. Oh and a link to an article and some benchmarks dealing with memory timings:

  4. Not sure of which BIOS settings to change? Looks like your being advised to set the following BIOS variables:

    Row-Active Delay = 11
    Row-Precharge Delay = 4
    RAS-to-CAS Delay = 4
    CAS Latency Time = 2.5
