Hi, A strange CPU behavior has appeared yesterday. No matter, what I do, it rapidly heats up, and cools down.
In idle it's 30c and stable. E.g I lauch browser - temp goes up to 50 or even more. (monitoring in aida64 and mobo onboard display), after the browser has loaded (1-2sec) the CPU goes back to 30c very fast. CPU fan rpm goes up and down, while the CPU temp jumps.
I click any link, open any document/programm (heavier than notepad or paint) and cpu temp jumps 30-55 and back. In BIOS the fan is set to quiete mode.
CPU cooler attached well. (I think the temp wouldn't be 30 in idle if the cooler was loose).
vCore 1.208-1.216. After 6 minutes CPU stress - 63c. Idle temp looks a bit higher - 32-34 against 30-32, or maybe my room got a bit hotter. vCore was greater before we started, so i think we shouldn't be heating up to much.
And, sorry for a lot of pictures. I want you to check me
If you want to we can but since you have such good temps I'd stick with 1.30v and see where that gets you.
Intel recommends no more than 64c for kabylake and 63c for stress testing is super good. Once we find your maximum overclock you can play a game to see where temps are as this is what really counts. Temps will likely be in the 40's and maybe 50's which is well within Intels thermal specifications.
