How to fix power delivery dips on MSI PRO B760M-A WIFI DDR4 II?
Whenever massive particle effects hit the screen, my frame rate would plummet from 110 FPS down to 45 FPS, making the whole experience feel completely choppy and unresponsive. Checking HWInfo, I saw the VRM temps swinging wildly between 82°C and 88°C, which caused the CPU core voltage to bounce between 1.15V and 1.28V. I first tried enabling the High Performance power plan in Windows, but that software tweak did absolutely nothing for the hardware-level voltage instability, which was honestly a waste of time. I eventually dove into the BIOS Advanced Voltage settings, switched the Load-Line Calibration from Auto to Mode L2, and manually locked the PL1 power limit at 125W. Monitoring via RivaTuner, the frame time variance shrank from a messy 12-35ms down to a tight 10-14ms. I did hit a snag early on where the system black-screened the moment I launched the game after trying a negative voltage offset; I had to bump the Vcore offset up one level to get it stable again. Now, VRM temps sit comfortably between 74°C and 79°C with a much smoother current distribution. After confirming the voltage curve in the motherboard control panel, the frame generation is finally locked in at 10-14ms.
