How to fix memory frequency fluctuations on Onda A520-VH-W?
The game had this nauseating 'sticky' feeling whenever I turned the camera quickly, which is a total mood killer in such a detailed city. Digging into the data, I found that the Onda A520-VH-W's auto-config was constantly switching frequencies under load, causing memory latency to bounce wildly between 92ns and 118ns. I tried increasing the page file to 32GB, but the minimum FPS stayed stuck around 38—software tweaks are useless when the hardware is fighting itself. I went into the BIOS, disabled the auto-overclocking nonsense, and hard-locked the RAM at 3200MHz with manual timings of 16-18-18-36. Looking at the RTSS frame time graph, those jagged spikes completely flattened out, and my 1% lows jumped from 38 FPS to 56 FPS. It wasn't a smooth ride; the PC randomly rebooted three times until I bumped the DRAM voltage from 1.2V to 1.35V. Now, RAM temps sit at 42-48℃ and the southbridge is around 54-60℃. After five clean passes in MemTest86, I can finally say it's stable. My eyes aren't straining from the stutter anymore.
