Hey i need some help OC my CPU. Its currently at 3.375ghz and its just about stable it occasionally crashes on The Witcher 2 but i can play BF3 for ages. Its cores idle at about 22c and under load 58-60 max. Its current voltage is 1.4750 but ive just upped it to 1.5250 coz i just OC a little more, about to check its stability. Most people ive seen are capable of 3.6-8Ghz on this CPU 24/7. Sometimes during heavy load it drops its Frequency down to like 980mhz for 5 seconds or so and then goes back, is this a heat issue?

My Rig:
Windows 7 64-bit
MSI Twin Frozr III PE 6950 2GB (850/1325 to 920/1400)
Asrock N68C-S UCC
Kingston 4GB DDR3 1333mhz
G7 Power extreme 680w
500GB 7200rpm Samsung

What cooler are you using ? Don't say stock...

Basically what I meant is that your motherboard is a budget board, cooler unknown but the PSU (although not the best) being 680watt should allow it.

Ok well my cooler is a Arctic cooling freezer 7 pro it keeps my cpu at 18c while idle and 52 max while stress testing. And even though my mobo is a budget board its main purpose is OC it can OC dual and tri cores to quads and comes with its own overclocking programme called OC Tuner.
