Tuning Crucial DDR4 2400 memory frequency for Planetside
Warping through massive space battles, my frame rate was bouncing like crazy between 40 and 65 FPS, and the instability was honestly jarring. The auto-voltage mechanism on my Crucial DDR4 2400 had a response lag of about 12ms under heavy load, causing the frequency to flip-flop between 2400MHz and 2133MHz. I tried enabling Windows Game Mode, but that just made my background updates more aggressive and did nothing for the stuttering—totally useless. I went into the BIOS, switched the memory voltage from Auto to a manual lock at 1.35V, and disabled all CPU power-saving states. In the RTSS frame time graph, the jagged sawtooth waves smoothed out into a flat line. I did have a setback where the system BSOD'd ten minutes into the game after the first voltage lock, but loosening the timings from CL16 to CL18 fixed it. Memory temps were 38-44℃, and the motherboard power delivery zone hit 60-66℃. Real-time analysis shows the fluctuations are gone, with frame times stable at 5.1-6.4ms.
