Can tightening tRFC fix stutters on Crucial DDR4 3200MHz?
Exploring the Lands Between is great until you rotate the camera and the game hitches. It's a tiny stutter, but it completely ruins the immersion. The default timings on this Crucial 16GB kit were sloppy, with latency swinging 75-90ns during asset loads. I tried dropping settings to Medium, which boosted the average FPS but didn't touch the stutters. I realized it was a timing issue. I went into the BIOS, crushed the tRFC secondary timing down to 560, and locked the voltage at 1.35V. AIDA64 showed latency drop from 82ns to a tight 68-74ns. The choppiness is gone. I did get a BSOD on the first try, but loosening tRAS to 40 stabilized everything. RAM is running 48-54℃ and VRMs are 60-65℃. Five passes of MemTest86 with zero errors. Now the world feels seamless.
