hiya kinc in 3d06 is it better to use cas 3 at a lower memory mhz than cas 4 at higher mhz,i always thought in 06 the higher memory bandwidth helps but looking at your setupo i can see you prefer the tighter timings at cas3, i can run at cas3 (3.3.3.8) up to about 450 (ddr900) with my 6400c3's corsairs or about 550 (ddr1100) at cas4 (4.4.3.10) which should net the better result in 06, thanks
