How to fix memory latency on MSI PRO B760M-A WIFI DDR4 II?
Riding through towns in Norway was a nightmare, with frames jumping wildly between 60 and 35. The optimization is just bad. While this MSI board has decent compatibility, the default JEDEC timings are way too conservative, leaving me with a latency of 85-92ns that choked the CPU's instruction scheduling. I tried adding 16GB of virtual memory first, but while usage dropped, the latency stayed exactly the same—a totally useless effort. I eventually dove into the BIOS and tightened the primary timings from 18-22-22-42 down to 16-18-18-38 and bumped the memory voltage from 1.2V to 1.35V. AIDA64 confirmed latency dropped from 88ns to a much better 64-68ns, and the city stutters are mostly gone. I did blue-screen trying 16-16-16 at first, but loosening tRFC to 560 stabilized everything. RAM temps are now 42-48℃ and VRMs are at 52-58℃. I've backed up the BIOS profile to keep these settings.
