ThrottleStop changed their UI little bit, so can you retake your settings please and in more detail?
I tried your configuration and I'm still getting jump in clock speeds, fans are at max. It worked for a while (5-10 min) and then it started to throttle. I have clueless in terms of how to fix this issue. that CPU tried to throttle down even with okay temperatures (from 80 degrees down).
First is from Apex Legends and second screenshots is from Kingdom Come : Deliverance
