How do I fix the power delivery on Biostar B650MT for ZZZ?
Whenever I hit a fast combo, the screen hitches in a rhythmic way, which is a total nightmare on the B650 chipset with stock settings. I fired up HWiNFO and saw the voltage swinging wildly between 11.6V - 12.4V under peak load, causing my clock speeds to tank from 5.2GHz down to 3.9GHz. I tried enabling 'Ultimate Performance' in Windows, but that was a disaster—temps spiked to 96℃ instantly, triggering a thermal throttle that made things even worse. I eventually dove into the BIOS, set the Load-Line Calibration to 'Medium', and applied a -0.04V offset to the core voltage. Checking RTSS, the frame time jitter dropped from a chaotic 14-38ms down to a much tighter 9-15ms. It wasn't a smooth ride, though; my first attempt at voltage tuning caused a BSOD right at the loading screen, and I had to bump the compensation back to +0.02V to get it stable. Now the VRM temps sit around 62-68℃ with fans humming at 1300RPM. Stress tests show a flat frequency curve, and the gameplay finally feels fluid with frame times locked at 9-15ms.
