Why is my Soyo SY-Yanlong B550M throttling in combat?
During massive boss encounters, my CPU temps were spiking to 88-92℃, causing the clock speed to jitter violently between 3.1-3.6GHz. The stuttering was honestly unbearable. At first, I thought my cooler was loose, so I wasted an hour re-pasting and tightening the brackets, but temps only dropped by 2℃. It was a total nightmare. I eventually dove into the BIOS Advanced Power Management and set the VRM Load-Line Calibration offset to exactly -30mV while switching the power mode to Extreme Performance. Using HWiNFO, I saw the core voltage swing tighten from 0.14-0.18V down to 0.06-0.09V, and frame times stabilized from a messy 16.2-24.5ms to a smooth 11.8-13.5ms. I actually tried lowering the power limit first to cool it down, but that just tanked my minimums to 20 FPS. Only after stacking the voltage offset and tweaking tRFC did the game actually feel fluid again. There are still tiny hitches during some loading screens, but it's mostly rock steady now. Verified the frequency curve with Cinebench to ensure thermal throttling is gone, with frame times locked at 11.8-13.5ms.
