How to stabilize memory on MSI PRO B760M-A WIFI DDR4 II?
The game would just vanish to the desktop without any warning during intense urban combat, which is incredibly frustrating when you're in a flow. It turns out the default XMP profile on my MSI PRO B760M-A WIFI DDR4 II had slight voltage drops at 3200MHz, causing the memory controller to hit 12-18ns of abnormal latency when handling massive entity counts. I tried increasing the virtual memory to 64GB first, but that was a waste of time—it didn't stop the crashes and actually added 5 seconds to my load times. I eventually went into the BIOS, 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. AIDA64 showed latency tightening from 88ns to a stable 82-85ns. I actually bricked the boot twice trying to push the timings too low, but after resetting and sticking to these values, it's perfect. RAM temps are 42-48℃. Four passes of MemTest86 with zero errors.
