@ WAZA88 I had LLC set to full. Problem is ASRocks shoddy cooling on the VRMs. Undersized heatsink and ineffective thermal tape. Even with 2x 120mm fans and a high-pressure 80mm fan cooling it it can't sustain more than 1.44V under load for more than a few seconds. I'm picking up a better Gigabyte board this evening.
@Martin White New motherboard is being installed tonight, I just may catch back up to you!
