How to fix RAM lag on MSI PRO B760M-A WIFI DDR4 II?
The RAM compatibility on this board is a total joke. In the high-load scenes of the tech demo, latency shot up to 85-92ns, leaving the CPU idling and causing noticeable hitches. I tried increasing the virtual memory in Windows, but that actually made the response time worse—totally illogical. I went into the BIOS and nudged the DRAM voltage from 1.35V to 1.38-1.40V and locked the main clock at 3200MHz. My monitoring showed latency dropping to 72-76ns, and FPS improved from a shaky 40-60 to a steady 55-60. I tried pushing it to 3600MHz at first, but that led to a loop of BSODs. After clearing the CMOS four times and manually tuning the timings, I finally got it stable. The VRM area hits about 65-70℃ under load, but it's solid now. I exported the timing profile as a backup, and latency is now consistently 72-76ns.
