How to fix frame time spikes on Kingston DDR4 2666 in Gears 5?
Whenever I'd snap between cover, the screen would just freeze for a microsecond, making the input feel sluggish and completely disconnected. The stock 19-19-19 timings on this Kingston DDR4 2666 kit are way too conservative, which caused the memory controller to choke during heavy particle effects, spiking latency to 95-110ns. I tried enabling Windows Game Mode first, but that actually made the stutters worse—it's frustrating how software tweaks fail when the hardware is the bottleneck. I eventually dove into the BIOS Advanced settings and manually crushed the primary timings down to 16-18-18, while bumping the DRAM voltage from 1.2V to 1.35V. After running AIDA64, I saw the latency drop from 102ns to a rock steady 78-82ns, and the game finally felt responsive. I did hit a wall early on when I tried 14-16-16, which immediately triggered a memory parity error and a BSOD; I had to loosen tRAS to 38 to get it stable. Temps sat around 42-48℃. I verified the timing curve via the motherboard performance panel, and it's finally holding up.
