How to fix bandwidth bottlenecks on Kingston HyperX Savage in Ark 2?
Whenever more than twenty large creatures appeared, my FPS would dive from 60 to 30, which completely ruined the immersion. I saw my memory bandwidth utilization hovering between 88-95%, causing a massive I/O bottleneck. I tried 'High Performance' mode in the drivers, and while the system felt more responsive, the stutters remained. I got determined to crush the timings manually. In the BIOS, I tightened the primary timings from 16-16-16-39 down to 14-14-14-34 and bumped the voltage to 1.35V. This gave me a 12% boost in bandwidth and made scene loading feel way more fluid. I actually broke the boot sequence once by pushing it too far, but loosening tRCD by 2 units brought it back to life. Temps are stable at 45-52℃. Comparing the frame time graphs, the spikes are basically gone.
