MGSV keeps crashing to desktop during stealth missions with Asgard Snow DDR5 6400, do I need tweaks?

There is nothing more frustrating than being at the end of a long stealth run and having the game just vanish to the desktop. The default XMP profile for the Asgard Snow DDR5 6400 was throwing 3 - 5 checksum errors at 1.4V when handling high-res textures, triggering a system crash. I tried dropping the graphics to medium, but the crashes kept happening, which told me this was a hardware-level instability. I disabled XMP and manually relaxed the primary timings from 32-39-39-76 to 34-40-40-80, while bumping the voltage to 1.42V. In MemTest86, the error rate dropped from 12 errors per hour to absolutely zero. I actually tried pushing the timings down to 30ns initially, but that resulted in an immediate BSOD until I loosened the tRAS to 82. Now, memory temps are a steady 52 - 57℃ and the VRMs are at 60℃. Four hours of gameplay and zero crashes—finally a stable experience.
