Why does my Biostar B550MH stutter during Nioh 2 combat?

At first, I was losing my mind during high-difficulty boss fights because the CPU clock was jumping randomly between 3.6GHz and 4.4GHz. The Biostar B550MH has a pretty lean power phase design, and during sudden current spikes, I noticed a voltage drop of about 0.11V, which absolutely trashed my frame times. I tried enabling 'Ultimate Performance' mode in Windows, but that was a disaster—my core temps spiked to 88-93℃ within three minutes without fixing the underlying power instability. I eventually dove into the BIOS power management and manually set the CPU Core Voltage Offset to +0.050V and tweaked the Load Line Calibration to Level 3. Monitoring with HWMonitor showed the voltage finally stabilized between 1.24V and 1.27V, and my frame swings dropped from 18 FPS to under 6 FPS. I did hit a snag early on where the system had memory training delays during boot, but bumping the DRAM voltage to 1.32V sorted that out. Now, my CPU stays chilled at 65-71℃ with fans humming at 1400-1600 RPM. According to the onboard logs, the voltage curve is finally flat, and my frame times are rock steady at 5.1-6.4ms. It's a relief to finally stop the stuttering.
