My ASUS B760M Artillery board is hitting memory overflows and freezing during heavy fights in Code Jie; do I need to tweak XMP?

I was loving the flow of the martial arts combat until a memory overflow froze my entire system, which is a total mood killer. With XMP enabled at 3600 MHz on the ASUS B760M, the memory controller voltage was drifting between 1.35 - 1.38V, causing random data checksum errors during heavy particle effects. I tried disabling XMP and dropping to 2133 MHz; it stopped the crashing, but I lost 20 FPS, which was just unacceptable. I ended up manually nudging the DRAM voltage to 1.38V and locking the VCCSA voltage at 1.20V to keep the controller stable under load. After four consecutive passes in MemTest86, errors dropped from 12 to 0. I actually pushed it to 1.4V once and the board just rebooted itself, so I had to back it off by 0.02V to find the sweet spot. RAM temps are now 42 - 48℃ and VRM temps are 58 - 64℃. I locked these settings in a BIOS profile, and the GPU is staying cool at 62 - 67℃.
