How to fix power limit throttling on Sapphire RX 7650 GRE?
It's unbelievable that a city builder can actually trigger a power wall. These micro-stutters turned my city expansion into a slideshow. I checked the logs and found the Sapphire RX 7650 GRE Platinum Edition was hitting a 160W limit, which forced the core clock to tank down to 1900 MHz during peaks. I tried turning on Windows Game Mode first, but the stutters didn't budge—it felt like a joke. I ended up using software to bump the power limit to 115% and manually set a core voltage offset of -20mV. Monitoring with RTSS, my 1% lows climbed from 35 FPS to 58 FPS, and the clock curve finally smoothed out. I did have a scare where VRAM temps shot past 88℃ immediately after raising the power, so I had to switch the fan curve to 'Aggressive' to keep it between 75 - 80℃. Core temps are now stable at 65 - 70℃ with power peaks hitting 175W. I've exported all the power logs for archiving, and fans are steady at 1400 - 1600 RPM.
