No idea! It's a gimpy little 'CPU burner' button that opens up some extra mini program... this was seriously done in about 30m of 'testing' before some gaming last night (which went without a hitch).
What is your AVX setting? I’d say if CPU burner uses AVX, your load temps are pretty good unless you turned AVX way down. Your idle temp seems very high to me, though - what is your room temp? Mine typically idles in the 28-32 range and using Prime small FFTs, hits a max of 77 on one core at 5 GHz (all other cores are in low to mid 70s) with AVX set to -2 and CPU-Z showing a CPU Vcore of 1.296. Under little to no load, I’m getting 28-32 (as I mentioned) but voltage shows 1.4. Still tweaking to get that down. The chip itself was binned at 5.1 GHz with AVX at -2 at a voltage of 1.412, but I don’t want to run that voltage 24/7.
Yeah, forgot to mention, AVX is -4 which I figured was prudent. Not sure if the CPU burner uses it, I have a funny feeling it isn't considering the delta from idle, but I do know that the CPU cooler is more than adequate (served me well for a year or so on my 4.7Ghz 6700k) so it's possible a lot of this is just my fan/pump settings, or hell, even my thermal paste.. Some old (seriously, like a decade old) arctic silver 5, since I had to scrape off the built-in paste off the thermaltake pad from the 6700k -> 8700k transition. Might need to invest in something better there.
I want to say when I was poking at it yesterday, I was at 4.8/4.9 and idling was more like 33-35.. I didn't spend too much time verifying that idle so it's possible there was some lingering heat from BTC mining that was heating the case beyond what it should have been, I'll try to spend some time tonight getting better stats on that. Room temp is like 20c, but the mining takes the cards up to like 75/80 (two in there) so now that I think more on it, my idle temps were probably just screwy because of that. The radiator is on the extraction side of the heat so it's bound to be contributing. I also know that the fans/pump curve is set to only 100% at 80c, so capped out it keeps the CPU under control.. maybe I'll draw that back to 70/75c instead, and make the fan curve a little more aggressive on the low-end.
I >think< I've got Prime installed on that thing, should check it though. That will give me more comparable numbers than that little burner doodad. I was impressed how easy it was to get to 5Ghz, like seriously no effort. Went from 4.7, 4.8, 4.9, 5.0 all at 1.28v with some brief (2-5m of aforementioned burner) testing, dropped to 1.27 at 5.0, dropped to 1.26, crash after a few minutes, revert to 1.27, and all's good so far. Maybe 20m to overclock the thing total. I spent more time than that on basically every build I've ever OC'd prior.
