Well I brought back my hackintosh a few weeks back, but yesterday I finally decided to insert my Vista drive back in. The purpose now is a 24/7 F@H rig! So I overclocked the 2500K to a nice 4.5ghz, and loaded up F@H to stress test and HWMonitor, CPU-Z and Gigabyte's Easytune 6 to check the temps and voltage.
My 2500K was running @4.5ghz with a voltage of 1.236V!! This seemed way too low, but then I checked all of the "major" softwares and found out it was correct.
