Why does Days Gone crash during combat transitions on the Galax B760M D4 White Phantom?

The game would just vanish to the desktop without any warning right as I entered a massive horde fight. After spending three hours on base building, that kind of crash is absolutely soul-crushing. It turned out the default XMP profile on the Galax B760M D4 White Phantom was unstable at 3200 MHz, causing voltage ripples that led to abnormal latency spikes of 14-20 ns during heavy asset streaming. My first instinct was to crank the virtual memory up to 64GB, but that was a waste of time; it didn't stop the crashes and actually added 6 seconds to my loading screens. I went back to the BIOS, manually bumped the DRAM voltage from 1.35V to 1.38V, and loosened the primary timings from 16-18-18-38 to 16-20-20-40. Running AIDA64 stress tests, the latency tightened up to a consistent 82-85 ns. I actually bricked the boot process once when I tried to tighten the timings too much, requiring a CMOS reset before I could fine-tune the voltage. Temps are now hovering between 42-48°C. After four consecutive passes of MemTest86 with zero errors, the system is finally stable.
