How to fix memory latency on MSI PRO B760M-A WIFI DDR4 II?
The game felt choppy as hell when moving through dense forests, with frame times jumping erratically between 16-42ms. It totally killed the immersion of the hunt. I traced it back to the default XMP timings on the MSI PRO B760M-A WIFI DDR4 II (18-22-22-42), which are way too conservative, leaving the memory controller struggling with massive terrain data and causing 85-102ns of latency. I wasted time increasing the page file to 64GB, but that just made the system feel sluggish—a total dead end. I went back into the BIOS Memory Advanced settings, manually crushed the primary timings to 16-18-18-38, and bumped the DRAM voltage from 1.35V to 1.38V. In AIDA64, the latency dropped from 92-105ns to a crisp 72-78ns, and textures started loading instantly. I did blue-screen three times trying to push the timings too far, and I only got it stable after relaxing tRAS to 40. Memory temps sat at 44-51℃ and VRMs at 55-62℃. Five rounds of MemTest86 showed zero errors. It's finally playable, but man, that was a struggle.
