Hello!
My i7 8700 was working just fine until I recently had to wipe my primary drive and reinstall windows, and now it's being power throttled according to IXT and wont go faster than 3.9ghz in stress tests. If that wasn't bad enough it won't turbo boost past 4.3ghz in single core cinebench (despite not being power limited there).
I can help it a bit by raising the turbo boost max wattage but I'd rather not fiddle with that stuff, and I didn't have to do anything like that before. Even doing that still doesn't let it turbo boost to 4.6ghz on single core tasks.
Any help would be awesome! So far I've tried changing the BIOS on my mobo (Gigabyte H370M D3H GSM) and not much else. Can't find any kind of power limiting setting on my BIOS anyway.
