How to fix black screens in Days Gone on X79 PRO?

Riding through the wilderness, the screen suddenly went black with a memory error; the unpredictability was agonizing. I first tried lowering the memory frequency in BIOS, which reduced crashes but tanked my minimum FPS from 52 to 41, leaving me discouraged. I used the GamePP BIOS Load-Line Voltage Adjustment Wizard to lock the VDD voltage at 1.55V and set the load-line to L3. MemTest86 errors dropped to zero, VRM temps stayed at 65-72℃ per HWMonitor, and voltage drop hit 0.08V per GPU-Z.
