Fixing memory timing lag in Ghost of Yotei on Maxsun B850M-K
While riding across the snowy plains, I noticed the frame rate dipping from 120 to 90 FPS; it's a subtle jitter but very noticeable during high-speed travel. The memory controller on the Maxsun MS-Challenger B850M-K was struggling with asset streaming, with timings jumping between 82-95ns, leaving the CPU hanging. I tried increasing the page file size, but that did nothing and actually slowed down system response by about 2 seconds—completely useless. I eventually went into the BIOS, switched the memory profile to Manual, and tightened the primary timings from 40-40-40-76 down to 36-38-38-72, while bumping the voltage to 1.35V. RivaTuner showed frame times settle from 14-28ms down to 8-12ms. I almost bricked my boot sequence by being too aggressive with tRAS, but loosening it slightly fixed the stability. Memory temps are now 48-54℃. AIDA64 confirms latency is down to 68ns, and frame times are locked at 8-12ms.
