Hello,
First, I am perfectly aware that 4.6Ghz is perfectly fine vs 4.7Ghz
I have been working on the OC of my new i7 6700k (on Asus z170 Pro Gaming, 16Gb Corsair ddr4 2133mhz) and found a stable result at 4.6Ghz - 1.36V. With air cooling the temp can go up to 80 degrees but it's usually in the 70 range.
I have tried working at 4.7Ghz but even with a 1.4 voltage, I get immediate errors on OCCT and Realbench can get me through 2/3 benchmarks before BSOD. The temperature stays ok, though (83 degrees big max).
I am waiting for my custom watercooling loop and I was wondering if getting my CPU to lower temps would have enough impact on the stability for me to reach 4.7Ghz. I actually know you can't answer for sure because there are many parameters involved, but I read somewhere that temperature has an impact on stability, even when critical temps are not involved.
What do you think?
Also, I never changed VCCIO nor VCCSA, should I try?
I'll keep you posted with my results with watercooling
Thanks!
