How to fix power throttling on ASRock H310CM-ITX/ac?
While galloping through the maple forests of Tsushima, I hit these brutal stutters that completely killed the flow of the game. I pulled up HWiNFO and saw the VRM temps on my ASRock H310CM-ITX/ac spiking between 88°C - 95°C, which forced the CPU clock to tank from 3.6 GHz down to 1.2 GHz instantly. I tried disabling all power-saving options in the Windows Power Plan first, but that was a disaster—core temps climbed even faster and the stuttering actually got worse. I eventually dove into the BIOS, navigated to Advanced $\rightarrow$ CPU Configuration $\rightarrow$ Voltage Offset, and set it to -0.050V while switching the Load-Line Calibration to Medium. The temperature swings dropped from a 15°C variance to just 5°C, and my frame times stabilized from 35ms down to 18ms. It wasn't a straight path, though; the system rebooted twice until I backed the offset off to -0.030V. Now the VRMs sit steady at 72°C - 78°C with fans humming at 2200 RPM. After a three-hour stress test, the clocks are rock steady and frame times stay between 18ms - 22ms.
