I have been playing with my processor had it running at 4.9 stableish(10 min torture) at 1.30v usual nasty temps though, but just noticed something weird at 42 ratio and a BCLK of 103mhz it is rock solid stable at 1.19v (2 hours of stress 72 Max temp in silent case fans all running low) but if I up the ratio to 43 it needs 1.25v to be stable yet at 44 it is stable at 1.22v. Not a big problem as Ill be leaving it at 43 @1.19v just because the machine is never turned off just an odd thing that happened.
