i5-2500K/2600K batch number and o/c results

Wow, man, you saved me. I couldn't get anything beyond 4.5Ghz, It took 1.39v load to get it stable at that speed and even 1.45v wasn't enough for 4.6Ghz
I though I was stuck at 4.5Ghz, but tonight I finished 6Hs of prime blend at 4.6Ghz with 1.4V and now it passed 30 minutes and counting at 4.7Ghz with 1.428v (66°C / 72°C full load).

All I did was set the CPU PLL to 1.600v, instead of 1.800v. The Internal CPU PLL Overvoltage is enabled. Do you think I could lower the vCore even more without it?

Thanks, I'm starting to like this chip

From the looks of it your chip is behaving very much like my own. In that case you should be able to go down to 1.365 then work your way down. But once again I'm not sure what exactly did it, the CPU PLL overvotalge OFF or the actual CPU PLL voltage (can anyone explain how the two are related?).

Try 1.365, but boost the CPU PLL to 1.63125...because my prime failed after 45min...I'm still working things out, Im trying more cpu pll to see if that caused the crash before I give it a tad more vcore, I would like to stay at 1.34.
