i5 8600k Power Limit Throttling in Prime 95?

[nightfxll]

Recently got a 8600k and decided to OC but for some reason only in prime 95 (26.6) it throttles down 100 - 200mhz any other stress test I try has no issues using aida64 extreme, cinebench r15, Intel XTU. Along with that my cpu never hits above 68c mostly 50 - 65c underload so it leaded me to believe its either VRM or Power limit throttling. But when using INTEL XTU to monitor and Prime95 to stress test XTU reports that Power Limit Throtttling is the cause, and the throttling happens around 1 minute into p95. Is there anyway to up the limit or would that damage the chip in anyway?

Using HWMonitor & CPU-Z to monitor as well.

Motherboard: MSI z370-a pro
CPU: i5 8600k
running at 4.7ghz @ 1.16v

I know my motherboard isnt the best but some videos and reviews said is was one of the better ones for ocing for its price range.

Thanks alot!

i would guess the same as you, vrm. can you put a fan on your vrms and test again? do you have a laser thermometer? 1.16v@4.7ghz shouldn't be of concern though... that is throttling?

Finally got it to stop throttling, turns out it was power limit throttling lol. Raised turbo boost short power limit and turbo boost long power limit to 150 and its working fine.

Thanks for your help!

i would just max the short and long limit out.
