Hi AnonGhost

I'll give you a hand if you like, I have my 7700k delidded and overclocked to 5.2GHz, you have a good cooler and should allow for a nice overclock.

What do you say would you like to give it a go, do you have ROG Realbench and HWinfo installed ?

Hwinfo Native 64 bit.

Ok good !

It might be best to close CPU-Z and just use HWinfo.

AI Overclock Tuner - Manual
Sync all cores and set the CPU Core Ratio to 45
CPU Core/Cache voltage - 1.30v

In DiGi+ set LLC to level 5

Let's try this as a starting point and see where voltage and temps are.

Open HWinfo and Realbencnch, run the benchmark then post a screenshot of Hwinfo. To get all the information to show in HWinfo click the blue arrows at the bottom left.
