Why does my ASRock B450M-HDV R4.0 struggle with resource scheduling?
During high-speed combat maneuvers, my frame rate was swinging wildly between 90 and 45 FPS, which made the controls feel like a total mess. I initially thought it was a thermal issue, so I cranked my fans up to 2200 RPM. While temps dropped by 5℃, the stuttering stayed, which was honestly pretty frustrating. After digging into the Vcore voltage curves using HWiNFO, I noticed the ASRock B450M-HDV R4.0 had a sudden 0.15V dip during load spikes, triggering a massive clock drop. I jumped into the BIOS, switched the voltage mode from Auto to Manual, and locked the Vcore at 1.32V while disabling Global C-State. My CPU clock finally stopped bouncing between 3.6-4.2GHz and settled at a rock steady 4.1GHz. One heads-up: the VRM temps spiked to 95℃ right after locking the voltage, so I had to rig up a small 12cm fan to blow directly on the power phases to bring it down to 78-82℃. With system power draw sitting between 85-92W, the game is buttery smooth now, and frame times are locked in at 5.1-6.4ms.
