My 2500k hit 5 Ghz with ease, my Haswell is junk I'd need 1.5v I think. What voltage did you go to? 1.4 I'm guessing @ 80 degrees? Did you BLK to 110?
I had to go high on the voltage due to the motherboard fluctuating, it probably would have worked at 1.5. I've since then found a couple of settings to improve stability i could probably try it again and get 5.0 at lower voltage and all cores. i didnt touch the BLK. temps didn't break 60 even after an hour of constant reboots at 1.5+ volts
awesome build man
