Why does my Soyo SY-Yanlong H410M cause CPU clock jumps and stutters in Overwatch 2?

The power delivery on this board is basically walking a tightrope. During firefights, the voltage jumps around like an EKG monitor—it's honestly ridiculous. The game was bouncing between 120 FPS and 40 FPS, making the whole experience feel like a slideshow. I tried locking the CPU at 3.5GHz, but then loading times became glacial, and I felt like a total amateur for crippling my own rig. I went back into the BIOS, set the Load-Line Calibration to Level 2, and moved the fan trigger threshold from 52℃ down to 42℃. HWInfo now shows the core frequency stable between 3.9-4.1GHz without those cliff-dive drops. I did have two random reboots during idle after the first voltage tweak, but fine-tuning the Vcore to 1.18V finally nailed it. VRM temps stay between 83-89℃, and the fans are screaming at 2100 RPM. I exported all the voltage and frequency mappings for my records; the fans are now locked in at 2100-2200 RPM.
