I didn't push it any higher anymore, the frequency is now 3450Mhz. Here are the voltages:
Cpu Vcore: 1,358v from bios (1,320v stable with vdroop mod CPU-Z)
FSB Termination voltage: 1,34v
DRAM voltage: 1,7v
NB: 1,25v (stock)
Ram is currently at 690Mhz 7-7-7-18
Hehe, tested Cinebench 11: stock 2,95, now 4,15. Smex, thanks for your advices!
Edit: Why don't I stop? I tested cpu multiplier at 7, still the fourth core fails at 465FSB. 460FSB is stable at x7 and x7.5.
