My ram is unable to go tRC=7 even @150mhz. And if i have LN2 to push 230*9.5, I would better try freezing ram and go 200-210*10.5 1:1 2.2.2.7 PIII 1.4S to break 1 minute.
I think Vnb may yield some stability for long benches @high FSB + tight timings. I plan to check this somewhere this week when I find my best Coppermine 733. I don't think that Vnb effect can be seen from CPUZ valids.
me too don't like inconsistency of new benches (catzilla is da worst for 4gpu CFX setup - 2 different runs have 1.5 difference with just the same settings).
