I'm getting random stutters during parkour in Dying Light 2 on my Colorful B760M-D PRO V20. Do I need to tweak the memory voltage?

While leaping between rooftops, the game would freeze for about 0.2 seconds—it's a tiny hitch, but it completely kills the flow of parkour. I used some monitoring tools and found that with XMP enabled at 3600MHz, the voltage on the Colorful B760M-D PRO V20 was fluctuating around 1.35V, causing occasional memory parity errors. I tried dropping the frequency to 3200MHz, which stopped the stutters but cost me about 8 FPS, and I wasn't about to accept that. I went back into the BIOS, bumped the RAM voltage to 1.38V, and loosened the tRFC timing to 600 cycles. After 4 passes of MemTest86, the 12 errors I was seeing completely disappeared. My RAM temp hit 52℃ at first, so I cranked up the front case fans to bring it down to 44-46℃. CPU temps are steady at 62-68℃. Latency tests confirm no performance loss, and frame times are now a smooth 5.1-6.4ms. It's a bit of a hassle to tune, but it worked.
