I got a I7 6700k overclocked to 4.6GHz @ 1.32xV, but I wonna push it to 4.7GHz, buuuuut i don't know what the highest voltage should be? My cooler is a Corsair H100i v2 and the board I'm using is a MSI Tomahawk AC (Best board I've tryed for 100£). What stabilisation testing program should I use? Now I'm only testing with Cinabench and Intel testburner, but I'm getting way different temperatures. I went from 873CB to 998 without a GPU in Cinabench :)

Also what do you think about my English? My Englishteacher is saying that I'm not learning anything in English because I'm not listing and stuff, but I wonna proof him wrong, so if you could help me by saying hos good my English is, it would hemp me a lot :)


Thank you! <3

That's reasonably safe as long as you understand that even "safe" overclocking carries risks. Also, if it's stable at a lower voltage than 1.42, by all means keep it as low as possible. I would say that if 4.6 is stable at 1.32, 4.7 will probably be stable at 1.37-1.39. Good luck!

According to Asus, 1.40V is the max recommended for that chip for air cooling, and 1.42V is the max they recommend for water-cooling. I trust them as much as anyone.

"Good samples can achieve 4.7GHz with around 1.40 Vcore fully stable. The highest voltage we recommend using is 1.42V with triple-rad water-cooling if running stress tests with AVX2 routines (lower if ambient temps are high). Those not concerned with stress testing may wish to use up to 1.45V for maximum CPU frequency."

That's normal - different types of code will result in different levels of power consumption. I like RealBench because it seems to detect instability where other stress tests fail. It also stresses the CPU, GPU, and RAM all at the same time. I DO NOT recommend Intel Burn Test - the last time I ran it, my CPU and motherboard got fried.
