How to fix memory frequency fluctuations on B850M PRO WIFI?
Whenever I turned quickly, the screen felt 'sticky,' a sensation that is absolutely lethal in a high-stakes game like PUBG. Digging into the data, I found the auto-config on the Maxsun B850M was constantly switching frequencies during load spikes, sending memory latency bouncing between 85 - 112ns. I tried increasing the page file to 32GB, but the minimums were still hovering around 45 FPS—software tweaks are useless when the hardware is fighting itself. I went into the BIOS, killed the auto-overclock, and forced the RAM to a locked 5200 MHz with manual timings of 36-38-38-76. The RTSS frame time graph went from looking like a mountain range to a flat line, and my 1% lows jumped from 45 FPS to 68 FPS. It was a struggle; I dealt with three random BSODs before realizing I needed to bump the RAM voltage from 1.2V to 1.35V. Now RAM temps stay between 44 - 50℃ and the southbridge is at 56 - 62℃. Ran four passes of MemTest86 with zero errors, and the 44 - 50℃ temp range is holding steady.
