I get micro-stutters while riding through the map in Ghost of Tsushima on an X99. Fix?

Riding through those gorgeous maple forests should be zen, but I kept getting these tiny hitches that totally broke the immersion. Even though the Jginyue X99 Titanium has quad-channel memory, the effective bandwidth was fluctuating between 35GB/s and 42GB/s during asymmetric loading in modern games, leaving the CPU starved for data. I tried cranking the virtual memory to 32GB, but that just hammered my disk usage without touching the minimum frames—a waste of time. I went into the BIOS, pushed the RAM from 2133MHz to 2400MHz, and bumped the memory controller voltage to 1.2V. In AIDA64, the read speed jumped from 40GB/s to 48GB/s, and the stutters mostly disappeared. I did run into some random memory parity errors at first, but loosening the timings from CL15 to CL16 stabilized everything. RAM is now 45-51℃ and VRMs are at 60-66℃. The 1% lows climbed from a miserable 28 FPS to a much smoother 42 FPS.
