Hello everyone!

So, i have an i5 8600k and a z370 mobo, which is Aorus Ultra Gaming by Gigabyte.
i've done an OC to my 8600k, to 4.7ghz with 1.22V (cause with 1.20V the windows wouldnt even start).
It seems it all okay, i mean, windows starts, no bsods, no freezes, no nothing, all stable.
Temps are less than 35c in idle and gaming it goes to 70c max.

I have a question about the vdroop tho...i played overwatch for like 2 hours and after i stopped gaming, my HWINFO64 showed me that the minimum vcore was 1.188 (something like that, so 1.18V).

I gotta ask, is it okay to let this way? if the PC doesnt crash while gaming with vcore on 1.188v, is it fine? I gotta say i think it's weird that the pc needs at least 1.22V to windows start, but it doesnt crash when gaming with 1.188V...is there an explanation for this?
OBS: my LLC is on High, i dont like it on Turbo

What you describe all seems like normal power management by modern processors. It does take more voltage to boot into Windows than it does to be stable at idle while already in Windows.

It's common for overclockers to find that the next to the highest LLC setting is about right.

Have you done any serious stress testing like with Prime95, OCCT or AIDA64 to confirm stability in the overclock?

hey!

yeah, i did prime95 for like about 2h a long time ago with this settings.
It was okay, the temps were higher than 70 but less than 80, i think 75 was max if i remember correctly and it was stable, no bsods freezes or whatever...
I know it's high temps but prime95 stress your cpu to the most and games dont do that, right? so my temps while gaming max is 70c and it seems fine for me

Those stress test temps are not high at all. We don't worry about temps on the newer Intels until you get to almost 95c.

True, games wont jack up temps like dedicated stress tests do.

Those temps are fine. General rule of thumb with those chips are to keep stress testing temps around 90C or less. You can get instability above that before it throttles.

All good.

Thanks for the answers guys.
So, as long as the pc is stable i dont need to worry about the vdroop while gaming, correct?
