X2 550 Unlocking & Overclocking Consolidated

[darkblade74]

0925CPMW + Asrock M3A785GMH/128M(SB710) BIOS 1.20 - SUCCESS
Vcore 1.385V
NB Voltage 1.150V
ACC All cores + 4%
At first the processor had no desire to unlock. I had to overclock it as a dual core first. After a couple of hours grinding Prime 95 at 3.8 GHz dual core I gave it a second try. Had to bump All cores to +4%. Using Vcore 1.365V resulted in an immediate error in the 4th core when I started Prime95 Small FFT. A small boost to 1.375V fixed it. Still not 100% stable - AOE III Asian Dynasties kept kicking me out after 15-20minutes. Changed settings to ACC per core: Core0 +2%, Core1 +2%, Core2 +4% and Core3 +6% - rock solid.
Now I've got to see what it is capable of in 4core mode.
