Fixing bandwidth competition on Galax B760M in Dragon Age
Whenever I enter a crowded city, the game just twitches, which totally kills the immersion. The Galax B760M D4's PCIe link was fighting with the memory channels for resources, creating 15-22ms of competition latency. I tried cranking the virtual memory to 64GB, but that just hammered my SSD and actually made the stutters worse—definitely a mistake. I went back to the BIOS, forced the PCIe link to Gen4, and overclocked the RAM from 3200MHz to 3600MHz. Using a performance analyzer, I saw the random read latency drop from 18ms to about 9-11ms, and the transitions became buttery smooth. I had some memory parity errors at first, but a tiny 0.02V voltage bump fixed it. VRM temps are sitting at 52-58℃, and the loading drops are finally gone.
