My 990fxa UD5 is throttling my 8320. My cpu temps are staying under 60 (this does depend on LLC settings, but not my cpu core voltage setting.) I have it so its not vdrooping hard, it goes from 1.488 to 1.5 when I hit it with load. I have had temp issues (large spikes or not being able to hold temp down) at lower voltages, seems to be something to do with having everything in sync. I have an old blower style fan on the vrms, which are not getting hot. I have cool and quiet disable as well as turbo and all the other normal things. I did have to disable HPC mode, other wise it was throttling 6 cores all the time and 2 were at the settings I set. All my voltages have a small bump, the NB settings are up a bit higher than everything else. most are .015. I just raised everything a bit earlier on as a band aid attempt to hold 4.8. 850w corsair psu, have a 650 I can add to split load up if I need to, but I know I shouldn't have too.
