Hi jarokamaro007 and thanks for the report.
Your temps are a little high with your system at 4.7GHz stock and core temp at 77c under load.
Mine tops at 66-68c on small FFT, so there is only a little more headroom for 5GHz unless you can improve your cooling. (Fans and radiator)
One way is to add a small fan to the backplate behind the CPU, as I have done and gained around 4-5c.
Your next step is to raise your multiplier in the Bios to 24.5 for a 4.9GHz OC.
Set AI overclock tuner to manual.
Go to DIGI+ power control and set CPU load line calibration to high and CPU current capability to 120%.
Leave the rest on Auto for now.
once set, key in static values for NB and HT. and using the + and - keys to increase CPU frequency, then save this profile.
exit Bios and reboot.
You are now going to stress test this without any voltage increases initially, so run your stress test again to see how much CPU temp increases.
(You are probably going to get annoying warnings from AISuite)
If you are stable at 4.9GHz, then increase your core voltage a couple of small steps up and change the multiplier to 25 for 5.0GHz.
Your temps will determine how far you can go, Only make small changes at a time and do not make arbitrary changes without knowing what they do and the consequence of that change.
It may take quite a few reboots and tweaks before you reach your goal, so take your time and have fun.
Please report back with results.
