Genshin Impact stutters when I switch scenes or use skills on my MSI MPG Z890 EDGE TI WIFI; do I need to raise RAM voltage?

While exploring the open world, I kept getting these tiny micro-stutters that were super noticeable during fast combat. The MSI MPG Z890 EDGE TI WIFI defaults to 1.1V for RAM, which was causing 15-22ms latency spikes during high-speed data swaps. I tried lowering the in-game graphics, and while the average FPS went up, the stutters were still there, which told me it was a hardware-level issue. I went into the BIOS and carefully bumped the RAM voltage to 1.35V and tightened the timings from 36-36-36-76 to 32-34-34-72. RivaTuner showed the frame times collapse from a wild 16-45ms range down to a steady 12-16ms. I actually messed up once and set it to 1.45V, which bricked the boot process until I cleared the CMOS. Now, RAM temps are 42-48℃ and the motherboard core is 50-55℃. After four hours of gaming, the stutters are gone and fans are steady at 1400-1600 RPM.
