Hello.

A few days ago I decided to overclock my CPU and GPUs to get a bit more power because why not,
I OCed the 1070 GPUs fairly easily and there've not been any problems with them.

For the CPU, I ran an 'auto-tune' program from Gigabyte that came with my motherboard, that basically increased the core clock one by one from 33 and stress tested it each time, and it recommended 4.4Ghz for me and set the voltage to (i think) 1.25V or something close.
I then restarted the PC, but when Windows started, I noticed the changes were gone, so I thought maybe it'll be better if I OCed through bios, so I applied the same settings there and it was fixed.

I then ran both Aida and Asus Realbench tests, each for about 30 minutes, and there were no problems. Max temps at 92C. Also worked with 3D programs as I usually do, for several hours, no problems. Temps at ~60-70C under load.

I shut down the PC, turn it on the night after, and it keeps restarting right after showing the motherboard logo.
After 2 tries it automatically goes to bios settings and recommends loading optimized settings.

I load optimized settings and everything boots up perfectly.
Then I tried to OC again through bios, again, it wouldn't boot.
Also tried leaving voltage on Auto, still wouldn't boot. Also tried 4.3Ghz with no success.

So, what do you think is happening? The temps have always been fine and below 80C, and I could hear the Hyper 212X going at full speed when booting (as it always does until Windows loads up) so I doubt overheating is the issue.

I appreciate any help!

Thanks in advance

That's fair but I also want to know what exactly the problem is before losing the extra power, since this is all a bit weird. If it wasn't going to handle 4.4Ghz, why did it not show in stress tests? This makes me think that there may be another problem.
