Hello Users.
I'm just starting here and English isn't my first language, so please be patient.
I'm trying to overclock my CPU - i5 8600k on Z390 Aorus Master - Mobo. It's delidded; something seems wrong because its overdel limit is lower now. I'm open to buying an i7 9700k but for now I'm using the old CPU.
I overclocked it to 4.8 GHz and set a stable Vcore of 1,365 V. The CPU is stable and passed a 40-minute OC test, but the Vcore readings look off. Under load, CPUCP shows 1.25-1.3V while HWInfo says 1.26-1.305. The most unusual thing is the OCCT reporting 1.6-1.7V. I'm a bit worried, though—I think the OCCT numbers might be incorrect and the readings are unreliable. The CPU reaches up to 61°C.
All programs are the latest versions I could find on developer sites.
Thanks for your help everyone.
P.S. I didn't turn off C-states, so the Vcore is dynamic but set at 1.365V.

OCCT hasn't been refreshed for a while. I wouldn't bother using it either.

You don't have to worry. As long as the results stay at 63 max temperature, you can maintain your CPU's clock speed.
