Fixing I/O blocking and micro-stutters on ASRock A320M-HDV
Swinging through Manhattan is great until the game hitches at 90% load, which felt exactly like the old single-channel RAM days. The bus bandwidth on the ASRock A320M-HDV R4.0 is just struggling with modern open-world streaming, with I/O latency hovering around 95 - 110ms. I tried 'High Performance' power mode, but read speeds didn't budge—I realized the issue was scheduling, not power. I used the services manager to kill every non-essential Windows telemetry service and locked my virtual memory at 16GB. In Resource Monitor, disk response time plummeted from 120ms to 35 - 48ms. I actually accidentally deleted a driver component during the process and lost my internet, but a registry reload fixed it. Board temps are 58 - 65℃. Loading times dropped by 4 seconds, and core temps are steady at 62 - 68℃.
