Mass Effect Legendary Edition is dropping frames when loading large maps on my MSI B760M-A. Why?

While warping across the galaxy map, I'd get these tiny, annoying frame skips that felt terrible during combat. The memory controller on the MSI PRO B760M-A was hitting 1.2-1.8ns of signal interference at 3200MHz, causing read latency to swing between 75ms and 110ms. I tried just enabling the XMP profile, but that actually increased my random reboot rate—a cautious move that didn't hit the root cause. I eventually manually bumped the DRAM voltage from 1.35V to 1.38V and loosened the tRCD parameter by 2 units. In AIDA64, the read/write variance dropped from 20% to 5%, and the stutters became barely noticeable. I did see a 3℃ rise in RAM temps, but a quick adjustment to my case airflow fixed that. RAM temps are now holding at 42-48℃. After 4 hours of stress testing, the frame drops are gone, though I suspect the motherboard's memory traces are just mediocre.
