Nothing is Overclocked right now, everything is at stock.
-thanks for the help!
Welcome to the forums
As for the bolded part, that's absolutely incorrect.
Only time that's ever true is with nForce chipsets running synced 1:1 with 1T; otherwise it's basically always the slowest possible ratio.
So nope; you'll see a performance decrease.
tRD aka Performance Level is much higher at defaults or when manually set using 1:1 than 5:6 or any of the higher ratios on your mobo, which means by going to 1:1, you'd be loosing bandwidth & latency bigtime.
If anything, you should be trying to run the RAM at a higher speed, like DDR2-1000+.
BTW, none of these memory adjustments are going to make a huge difference in real world usage.
But when it comes down to it, bandwidth is king on Intel chipsets.
So if you want the best performance (even if you can only see it in benchmarks), stay away from 1:1.
5:6, 4:5, 2:3, you name it...they are going to better pretty much everytime.
Grab Everest if you want to be able to see the small differences that can be made by RAM...it shows in a big way the little differences RAM speeds/timings/ratios make.
