Why is my Soyo SY-Yanlong B550M power delivery unstable?

Right when I'm unleashing a flashy skill, the screen hits this tiny, weird hitch. In a 60 FPS environment, it feels totally disjointed. I dug into the telemetry and found the SY-Yanlong B550M VRM was spitting out 18-25ms voltage ripples, causing the Vcore to bounce wildly between 1.15V and 1.3V. I tried enabling 'Ultimate Performance' in Windows, but that was a joke; average FPS went up by 3, but the stuttering actually got worse. I finally dove into the BIOS, swapped Load-Line Calibration from Auto to Manual L3 mode, and bumped the CPU core voltage offset to +0.015V to stop the sagging. Running AIDA64, the clocks finally locked in at 4.1-4.3GHz, and the frame time variance shrank from a messy 15-30ms down to a tight 9-16ms. I actually triggered a system protection reboot during my first aggressive attempt, and I had to dial it back by 0.01V to find the sweet spot. VRM temps stayed around 76-83℃. Saved the profile to the motherboard, and it's finally rock steady.
