Hello,
So I recently overclocked my 8700k to 4700mhz on all cores. It was my first time OCing. First stable voltage was 1.28. I tested it 2 times in RealBench for 1 hour and run some benchmarks,play games and it was stable. Temperatures in stress test were around 80C- 85C (sometimes spikes for 90+C but only for seconds, I watched entire time). In games temps doesn't go up more than 70C.
I decided to go back to stock settings anyway after that OC. Reseted mobo to default settings (AsRock z370 extreme4) and then I saw that in auto voltage mode mobo gives my cpu to much voltage (around 1.32v under stress test) so I thought if I OCed it and it works stable on 1.28v why should I use higher voltage.
Decided to change voltage manualy and set 1.15 first. PC got blue screen.
2nd try was 1.17 it passed stress test but HWInfo showed some cache error.
Then I changed for 1.2v and its super stable.
I think I can lower voltage more and set something between 1.17 and 1.2 but didnt have more time to run some tests.
Anyway my question is if lower voltages can affect cpu (lower cpu performance even if it passed tests ) ? I mean ... I thought auto settings should well personalized and then I saw this hight voltage mobo gives to my cpu and I'm confused now.
I know lower voltages = lower temps , but dont know if it affects performance somehow.
Sorry you had to read all this long story , I should just write this question
