How to fix RAM instability on ASRock A320M-HDV R4.0?
Walking through medieval towns was giving me these tiny pixel flickers and 0.2s freezes that made me really uneasy about my hardware. The RAM slots on the ASRock A320M-HDV R4.0 are packed so tight that running at 3200MHz was causing noticeable EMI, leading to 3-5 retry requests from the memory controller. I tried enabling memory compression in Windows, but that just dumped more load on the CPU and cost me 4 FPS. I eventually went into the BIOS, dialed the frequency down from 3200MHz to 2933MHz, and bumped the voltage from 1.35V to 1.37V to clean up the signal. AIDA64 stress tests went from 8 errors per hour to zero, and frametimes settled into the 16-20ms range. I lost about 6% bandwidth, but honestly, that's a fair trade for a system that doesn't glitch out. Temps are 44-50℃. Four hours of testing and it's finally rock solid.
