Your FSB:RAM ratio should be at 1:1 for the best performance

So your ram would have to get at an 1100 effctive speed (DDR1100) to match your 275FSB.

Try that, by loosening your timings and see how high it'll get.

slowly tighten em and test for stability.

1100 for ram is a huge achievement btw you could always run dual channel and put your ram at 550 /w tighter timings

WHAT? No it wouldn't. To achieve 1:1 you really just need to have your ram multiplier at 2x. 275x2 = 550.

My FSB is 400 (1600mhz) right now, my Ram is at 400mhz (x2 = 800) and my ratio is 1:1
