Similar to AshleyAshes1983 below, I easily OC'ed my 2500K too. On a Gigabyte GA-Z68A-D3H-B3, all I had to do was tell the BIOS "run at 45x, not 33x", and it's running like a champ. Peaks around 70c with a Hyper 212+ cooler, which was about $25. Bumping voltage a bit got me to 4.7, but at higher temps. Dropped it…
