How to fix Dragon's Dogma 2 crashes on MSI B450M MORTAR MAX?

I was anxious when Dragon's Dogma 2 kept crashing during combat on my MSI B450M MORTAR MAX. I tried lowering RAM frequency by 200MHz, but it caused blue screens. I used GamePP BIOS Load Line Voltage Adjustment Wizard to change timings from 16-16-16-36 to 18-18-18-38 and set voltage to 1.30V. MemTest86 now shows zero errors, with RAM stable at 42-48°C and CPU temp at 65-72°C per AIDA64.
