Help with K8V Memory Ratios

Which ratio do i need to select in the K8V Bios to get my ram to run synchronous with my FSB (HTT, whatever)? I've set it to 2:1 (DDR 400), with my fsb at 220, and my ram's running at 172mhz . Thanks.

The problem is that this board only lets you use your rams defaults. Pc3000 is 185fsb. Even if you did 1:1 or 2:1 or just did auto your not going to get the 200 that the chips at.

I have a gig of 2100 that will do 220fsb but this board will never let me use it. Highest i can get is 240:154.

Ugh. That's retarded, but thanks for explaining that one.
