How to fix memory latency for Kingston DDR4 in Primal Carnage?
There is nothing worse than that tiny, jarring stutter right when a dinosaur is lunging at you; it completely kills the immersion. Digging into the hardware logs, I found the Kingston 16GB DDR4 2666 was hitting high latency spikes of 110-125ns during heavy instruction loads. My first instinct was to enable the motherboard's auto-overclock, which pushed it to 3000MHz, but the game would BSOD within thirty minutes. It was incredibly frustrating. I went back into the BIOS, manually bumped the SoC voltage from 1.1V to 1.2V, and loosened the primary timings from 16-18-18-36 to 18-20-20-40. In AIDA64, the read/write latency tightened from 115ns down to 85-90ns, and those annoying hitches vanished. I actually had two failed boots during the voltage climb, only stabilizing after I nudged the DRAM voltage to 1.35V. Memory temps stayed between 40-46℃, and the chipset hovered around 52-58℃. After six full cycles of MemTest86 with zero errors, it's finally playable.
