How to fix RT500 TC ARGB thermal throttling in Expeditions Rome?
The screen tearing became unbearable after two hours of campaigning. Checking my logs, the CPU hit a wall at 88-92℃, and the clock was forced down to 2.1-2.5GHz. I tried just lowering the room temperature, but that was a joke compared to the actual heat load. I had to go into the hardware settings and cap the PL1/PL2 power limits to 125-130W while locking the RT500 fans at 1600-1800 RPM. My sensors showed the core temps finally dropping to 74-79℃, and those erratic frame time spikes of 12.4-22.1ms settled down to 9.2-11.5ms. I actually bricked my stability at first by trying a negative voltage offset, which led to three BSODs before I found the sweet spot. There's still a tiny bit of hitching during heavy asset loading in complex maps, but it's night and day. Stress tests confirm no more thermal throttling, and my RAM is sitting comfortably between 58-63℃.
