Fixing random crashes in Scarlet Nexus on MSI B450M Mortar Max
I was in the middle of a high-speed fight when the game just vanished and dumped me back to the desktop with zero error messages. It turns out the default XMP profile on my MSI B450M Mortar Max was causing the VDD voltage to swing wildly between 1.3V and 1.4V during high-bandwidth loads, triggering the memory controller's protection. I first tried downclocking the RAM to 3000MHz; the crashes stopped, but loading times got noticeably slower, which made me really hesitant. I went back into the BIOS, manually locked the VDD voltage at 1.35V, and loosened the tRFC timing from 480 to 560. After 4 consecutive passes in MemTest86, the errors (which used to pop up every two hours) dropped to zero. I actually tried 1.4V first, but the RAM temps spiked to 62℃, so I dialed it back to 1.35V. Now, temps sit at 48-54℃, and the game is buttery smooth. System logs show no more memory management errors, with temps idling at 45-50℃.
