actually i think maybe able to do it. if you set the memory timimgs to "manual" in the BIOS and change the timings to 5-5-5-15 what happens?
PS- i am also using PC6400 corsair but CL5 version
The way it was, gave error on Prime95 in the 2nd minute ...
Just did an 1H10 minute test @ higher VCore (1.35 with LLC disabled) using multi 6 to rule out memory problem and it worked. It lowers the VCore to 1.2960 under load, and the temps dropped to 65º but @ the cost of a high FSBT and a higher (then what i used to have) NB, though with lower RAM volts.
The problem is that, with this setting, my RAM drops the Everest score by around 400 in memory read and gains a bit of latency. To make it @ 1062 with 5-5-5-15, even though it's much faster in MHz, it has a higher PL and higher latency and i end up loosing another 300 in memory read.
With CL5, i managed to make a few 3D06 runs @ 1062 MHz but Prime95 would crash in between 10 to 30 minutes.
It seams i have so more BIOS tweaking to do ...
