Ok I set my cpu at ~2160 for every test and left my 9800pro at stock. 2x512 sticks for all tests.
240FSB 11-3-3-2-2-13-15-e-d-n-d = 17815 3dmarks
216 11-3-3-2-2-9-12-e-e-f-d = 17363 3dmarks
197 11-3-3-2-2-9-12-e-e-f-e = 17366 3dmarks
197 11-2-2-2-2-9-12-e-e-f-e = 17570 3dmarks
240 11-2-2-2-2-13-15-e-d-n-d = 17877 3dmarks
What this means to me? For 3dmark (which I feel is the closest benchmark I have to gaming performance)...
ras-cas 2 is maybe 100-200pts advantage over 3.
the three ram settings after timings do very little.
cpc is worth ~ 15-30 FSB.
FSB seems to be worth 10-30pts in 3dmark so 200vs 250FSB should be about 500-1500pts apart. Big range, but it seems that it varys greatly based upon other settings.
