Your 990fxa UD5 is limiting your chip performance.
My 990fxa UD5 is limiting the performance of my 8320. My CPU temperatures remain below 60, though this varies with LLC configurations, not core voltage settings. I notice a change in temperature when under load—rising from 1.488 to 1.5. At lower voltages, I previously experienced temperature fluctuations and instability, which seems related to synchronization issues. The fan on the VRMs isn’t overheating, and I’ve enabled cool and quiet modes along with turbo settings. I had to turn off HPC mode; otherwise, it would throttle all six cores constantly, with two already at my adjusted settings. Voltages show minor adjustments, and most are around .015. I recently increased them slightly as a temporary fix to reach 4.8. The 850W Corsair PSU has a 650W capacity, which could be used for load balancing if needed, but I’m cautious about overloading.
So cooling works well when you're not dealing with 62c cores, but just one thing to check—are all RAM slots filled? Even though your BLCK is set to standard, the RAM might need a higher voltage. Since the MC is inside the processor, it can cause issues if both memory channels are active. This problem began with Bulldozer and has persisted through Vishera to now. Some believe that in such cases, RAM should not exceed 1600 MHz, even though the MC supports up to 1866 MHz.
I dropped it at 4.6 to catch some sleep. Ran a few small FFTs just because I wasn’t around much that night. https://gyazo.com/5878d2d87572a3088debfb71f956c0d6. On the positive side, it’s not throttling. It instantly improved my temps. At 4.8 with some throttling, it wasn’t affecting them. This thread is somewhat related to mine. My BIOS is stock, and I’m unsure which MMO version I have. I’ll answer questions and share more info tomorrow. The fans stay cold to the touch.
I believe the board I possess is different from what's shown in the screenshot. It could be throttling because the VRM is getting too hot. The thermal resistance will need some time to build up before it feels warm.

You mentioned having a 990FXA motherboard but in the screenshot I see 890G. Which one is it really? It could be throttling because the VRM is getting too hot.
The thermal paste will take some time to heat up, so it won't feel warm right away like the CPU does.
I agree and confirmed it's the 890G board.
It seems the software needs to be version 3.5 to function properly with the FX processor. I have one that uses a Ph II x4 965Be chip running at 4.2 GHz and 1.505v. It’s very capable, built to last, and should handle overclocking even with an FX 8320 since the PHII OC-ed version delivers around 140W under full load.
It is a 990fxa UD5.
