I'm getting frame drops and memory checksum errors during scene transitions in Genshin Impact on my Z890-A Snow. Should I tweak virtual memory?

Whenever I'm sprinting through the Sumeru rainforest, the screen just freezes for about 0.5 seconds. It's the kind of random stutter that makes you lose all focus. The default XMP profile on my ASUS ROG STRIX Z890-A Snow was unstable at 7200MHz, with the memory controller hitting 85-110ns of high latency during heavy asset loads. I wasted time increasing the Windows page file to 64GB, but it didn't stop the drops and actually made the OS feel sluggish—totally demoralizing. I eventually went into the BIOS and loosened the primary timings from 34-38-38-76 to 36-40-40-80, while bumping the DRAM voltage from 1.35V to 1.40V. After 4 cycles of MemTest86, errors dropped from 12 to 0. I had three BSODs while trying to push the timings too low before I finally loosened the tRFC parameter. RAM temps are now 48-54℃ and VRMs are at 55-60℃. The input response finally feels snappy again.
