so runmc's eVGA X58 241 was on sub zero cooling with ioh at 1.45+ v and 1.6 uncore IIRC and only validation





My 228bclk is super pi 32m stable and validation 231bclk all on air cooling with ioh at default 1.11v bios (dmm real same) and 1.5v uncore volts for i7 920 #2 and i7 920 #1 need 1.6v uncore (illustrates differences among cpus).

I can probably push bclk higher with right memory and voltages and sub zero cooling instead of air cooling
My Max BCLK seems to be 233-234, My max boot from bios bclk is 220 and my max stable bclk is 229 1 mb pi only. My voltages all read .05v or greater over in windows, but 1.65vcore and 1.6vtt gets me over 4.8GHz PI stable, still working an 3DMark Stable clocks.
