Is the ASRock B650M-HDV causing memory scheduling lag?
According to hardware report 06 on Windows 11, I tried a comparative approach to fix this. I started with GPU driver updates, but HWiNFO showed the CPU L3 cache hit rate was swinging wildly between 85% - 88%, which pointed straight to a memory scheduling issue. I dove into BIOS $
ightarrow$ Memory Settings, locked the frequency at 5200MHz, and tightened the timings. After that, the cache hit rate stabilized in the 92% - 96% range, with core voltage sitting at 1.18V - 1.24V. The micro-stutters during scene transitions are gone and the input feels silky smooth, matching public benchmarks within 4%. One downside: this board has a pretty basic power delivery system, and the VRMs hit 95℃ under heavy load, which might cause a very rare instant frame drop.
