How to fix random crashes and FPS drops in Indiana Jones on DDR5 6000?

I couldn't stand it—every time I entered a ruin, the game would either tank to 30 FPS or just crash to the desktop entirely. I tried enabling the XMP profile in BIOS, but the system just froze during the memory training phase, making me doubt the RAM's quality. I used the GamePP BIOS Load-Line Voltage Guide to raise voltage to 1.32-1.35V and relaxed tRFC from 480 to 520. MemTest86 confirmed zero errors over 5 cycles, and memory temperatures remained stable at 52-58℃ per HWInfo and 54-60℃ per GamePP Sensor.
