Why does my Galax H310M Warrior D4 experience violent FPS swings when speeding through cities in Neverness to Everness?

Whenever I pulled off high-frequency dodge maneuvers, the screen would hit these micro-stutters that completely murdered my combat rhythm. On this Galax board, after enabling XMP at 2666MHz, I noticed the memory controller voltage was bouncing wildly between 1.1V - 1.35V, which triggered occasional checksum errors. I initially tried switching the Windows power plan to High Performance, but while the average FPS ticked up slightly, the stuttering frequency didn't actually budge—it was a total waste of time. I eventually dove into the BIOS Advanced Voltage settings and hard-locked the VDDQ voltage at 1.38V, while nudging the SoC voltage to 1.22V. In AIDA64 stress tests, the error curve—which previously showed 3 crashes every 15 minutes—went completely flat, and my frame times tightened from a messy 12-28ms down to a steady 8-14ms. I actually tried pushing the clock to 3200MHz at first, but that just led to an immediate BSOD; I had to dial it back to 2666MHz and loosen the tRAS timings to get it stable. Memory temps settled around 48-54℃ with VRMs hitting 62-68℃. Everything is locked in and rock steady now.
