How to stop Gainward RTX 5070 Ti from throttling?
The power draw on this card is all over the place—jumping from 220W to 310W in a heartbeat, which just kills the boost clock. In scenes with heavy foliage, the core frequency would crash from 2.6GHz to 1.8GHz, creating 40ms spikes in frame time. I tried blasting my case fans at 100%, but while temps dropped by 3℃, the clock speeds were still diving. Total joke of a solution. I eventually used a tuning tool to bump the power limit by 10% and set a more aggressive fan curve that hits 80% speed at 65℃. Checking RTSS, the clock finally stabilized around 2.5GHz without those catastrophic drops. I did notice some coil whine when I first raised the power limit, but that disappeared after I swapped to a high-quality 12VHPWR cable. Core temps now fluctuate between 72-78℃ with fans at 2100 RPM. I exported the voltage and power data under full load to verify, and the fans are staying steady at 2100-2200 RPM.
