Hello all, just as the title states. I'm running an i5-4670k with a Corsair H100i water cooler. I had a (fairly) stable overclock at 4.4GHz and 1.245 volts. However, I cannot seem to get past 4.4GHz. Currently, I have 4.5GHz at 1.290 volts, LLC Level 2, and I can barely get into Windows. As soon as I start up OCCT, my entire computer freezes about 15 seconds into the stress. I was able to get a sucessful 5 run test on Intel Burn Test on Standard, but that seems to be it. I'm afraid I have one of the crappy Haswell cards to be honest. My temperatures max at 83 degrees on IBT, and that worries me also. So, what can I do to get to 4.5GHz? What's the maximum safe temperature and voltage I can get on my 4670k (thought it was 85 degrees and 1.3 volts)? Any and all help/suggestions would be greatly appreciated. Thanks!
