memory timings

[cheekykid]

I would like to ask how i figure out the best timings for my memory
I got a gskill PC6400 HZ and right now it runs at 800mhz 4-4-4-12-20

fsb: dram= 1:2 <-- is this ok? can it be changed? my board is asus p5w deluxe.

Danke

If you change the fsb:dram ratio it will change the ram speed. Have you overclocked your CPU?
