How to fix memory latency on MSI PRO B760M-A for CP2077?
Night City looked gorgeous with path tracing, but the weird rhythmic hitching made the whole experience feel glitchy. Looking at the specs, the default timings on my MSI PRO B760M-A (18-22-22-42) were creating random latency spikes of 12-18ns when handling massive ray tracing datasets. My first instinct was to just turn on Frame Generation, but that was a disaster—it pushed my input lag up to 60ms, making the controls feel like I was wading through mud. I couldn't stand it, so I went into the BIOS Memory Advanced settings and manually tightened the primary timings to 16-20-20-38, while upping the DRAM voltage from 1.2V to 1.35V. Using RTSS for frame time analysis, I saw the interval drop from a chaotic 22-45ms swing down to a consistent 13-17ms. It wasn't a smooth ride; I hit three consecutive Blue Screens of Death during the first few attempts until I loosened the tRAS from 38 to 42. Now, memory temps sit between 48-54℃ and AIDA64 shows zero errors. It's finally playable, although the RAM stays around 54℃ which is a bit higher than I'd like.
