As an 8350 owner with a 1080ti (used to run Strix 970) - I'm guessing temps. They are really easy to overheat and the throttling is quite severe. I only noticed it on Forza Horizon 4, where it would throttle from 100+ to 15fps. Not many other games (even VR) seemed to load the CPU as much to the point of overheat.
Run something that records max temps like openhardware monitor in the background - if you are hitting high 50's then its a cooling issue. On mine the heatsink was pretty dusty, a good clean and a slightly more agressive map on my case fans and I've not had a problem since. Also check that Cool n' Quiet is operating properly (openhardware monitor is good for that too) - I had an issue where the cores weren't throttling back properly when unloaded which generated heat for no reason.
hi! yau have a 1080 ti on this cpu, i think it's bottleneching your gpu, I have a tought that is's bottlenecking even my 1060 6gb gpu. since I have 25% lower passmark results even than 1060 3gb model, I have 7500 points and, someone on youtube reached 10000+ points with an later generation intel cpu. thank you for you tip. I ran prime95, after few seconds: freeze. I from 1.35V to 1.385 (1.375 was default i think) for few minutes and no crash, Cputin uped to 62C. (think that package temp that was 48C is not the real cput temp)and I stopped because I went to work. When I go home I'll change the thermal paste and try to put a small cooler on the vrm, and a 12 cm fan to pull out the hot air, having a top down cooler keeps the hotnes inside even if the cover is off. I don't understand well, I set up from Asrock Oc tunner the cpu to 1.385V, ran prime95, wathed open hardware and cpuid: when all cores 100%: max 1.328V max constantly, even cpu id reported a max 1.36V witch i never saw even in torture test. what is the reality? Thank you!
