How to fix memory frequency fluctuations on Ryzen 7 9700X?
Every time I flicked the camera quickly, there was this sickening 'sticky' feeling to the movement—absolutely unacceptable for a stealth game where precision is everything. Digging into the logs, I found the memory controller on my AMD Ryzen 7 9700X was drifting in auto mode, causing memory latency to bounce between 88ns and 112ns. I tried bumping the virtual memory to 32GB as a quick fix, but the 1% lows were still hovering around 45 FPS; software tweaks are useless when the hardware is fighting itself. I went back into the BIOS, killed the auto-overclocking, and hard-locked the RAM frequency at 5200 MHz with manual timings of 36-36-36-76. Checking the RTSS frame time graph, the jagged spikes flattened out instantly, and my minimums jumped from 45 FPS to 62 FPS. I did run into a couple of BSODs early on, but bumping the RAM voltage from 1.2V to 1.35V sorted it out. RAM temps are now 44-50℃ and the southbridge is at 56-62℃. Ran four passes of MemTest86 with zero errors, and the system feels snappy.
