How to fix high memory latency on Kingston DDR4 2666 in Starfield?
The screen tearing after interstellar jumps was a total nightmare, especially when exploring new worlds. Digging into the data, the default timings on this 2666MHz Kingston kit are way too conservative, leaving latency bouncing between 85-92ns and choking the CPU. I tried adding 16GB of virtual memory first, but while usage dropped, the latency didn't budge an inch—a complete waste of time. I went into the BIOS and crushed the primary timings from 19-21-21-42 down to 16-18-18-38, while bumping voltage from 1.2V to 1.35V. AIDA64 confirmed latency plummeted from 88ns to 68-72ns, and the world loading finally felt fluid. I did hit a wall early on; trying 16-16-16 caused two BSODs until I loosened tRFC to 560. Now RAM temps are 42-48℃ and VRMs are 58-63℃. Two hours of gaming without a single crash, though the 2666MHz ceiling is still a bottleneck.
