VRMs are possibly getting too hot causing the throlttling. Try %100 fan speed and see if that helps, just to test it out.

It will. But in the event that you need to RMA a card, you can always revert them back by either soldering them back on, or desoldering the connecting short wire.

same with my PE, it throttles at 108% power when i've added 20mV to the core voltage despite temps still being int he 60's

Well I managed to be ok at +40mV on the core, but +50 puts mine over.

VRMs huh... strange considering these cards are supposed to have beefy VRMs for the chip they're powering. I will try it, but 100% fan speed is annoying.

Well I understand where you are coming from. But to tell you something, the RIVE board that I have is a highend board. But doesn't have adequate VRM cooling. The board will throttle the cpu if that VRM area gets too hot, usually at 4.8-4.9GHz and above and over 1.4v for voltage. Unless that VRM area has a spot fan or is watercooled.
