How do I fix memory latency for Corsair Vengeance DDR5 6400?
Building a mega-city with over 100k pops was a nightmare; zooming out caused these weird, jarring stutters that made no sense. I noticed the memory controller on my Corsair Vengeance RGB DDR5 6400 was struggling with the massive entity data, with latency swinging wildly between 78ns and 92ns. My first instinct was to bump the virtual memory to 64GB, but that was a total disaster—it actually caused micro-freezes during page file R/W. I eventually dove into the BIOS and nudged the VDDQ voltage from 1.35V to 1.40V while locking the SoC voltage at 1.20V. Using AIDA64, I saw the latency tighten up from 84ns down to a rock-steady 62-66ns, and the city finally stopped choking. I did hit a wall early on when I tried to push the timings too hard and got two consecutive BSODs, which only stopped once I loosened tRFC to 480. Temps stayed around 52-58℃, though the RGB flickered a bit under full load. After verifying the resource allocation curves, my frame times finally settled into a clean 5.1-6.4ms range.
