Thats a nice overclock. Well actually the overclock is okay but the voltage is nice. I run mine at 4.7GHz 24/7 but can easily run over 5GHz but I need a lot of volts to do it. I envy the 2500k's that don't seem to need a lot of volts. I run 1.4v 24/7 for mine right now but if I go over 4.7GHz then I really need to start upping the voltage. If I could do 4.7GHz at that voltage you have then I'd be running 5GHz 24/7 for sure. My rig is stable up at that speed but the scarey high volts ....scare me lol.
