Replaced my 9600k with a 9900kf yesterday and got it to 5.0ghz all core boost as starting point @1.3v with LLC on high, vdrop now sets the voltage at 1.26v while benching. Can probably drop the voltage abit but as a starting point 1.3v seemed reasonable.
No bluescreens, no stutters, just runs flawless.
XMP enabled for 4 dimms 32gb 3200mhz.
However during prime95 Small FFT test, it runs fine initially until around test 7, the cpu usage will drop down to around 50% briefly before going back up to 100% again. This will continue doing so until i stop the test.
Anyone experience this before? Can't get my head around whats causing it. I've adjusted voltages up and down and it still does the same thing.
It's not thermal throttling, it sits around 78c average with the hottest core at around 82c.
Any help appreciated, thanks!
