Why set the fine delay step if you aren't manually setting the fine delays? I couldn't get my system to boot the 6/6/x combos. Could you post what the fine delays are for that model?

I am running 5/5/1 with the DRAM Skews set to 2100ps manual (30deg x 70ps adjustment). Lowly B3 Q6600. Passes 10+hours of Prime 95 @ 426fsb. Gets single cpu prime error after 1-8 hours at speeds 430-445, but will run 3DMark06 and appear to run without freezing at those speeds. Freezes at 450 and and higher.
