Solving memory latency spikes in Returnal with Crucial DDR5
During fast dodges and attack combos, the frame rate would randomly tank from 100 to 60 FPS, which totally kills the flow of combat. The default timings on this Crucial kit were hitting 80-90ns latency when processing heavy particle effects. I tried enabling Game Mode in Windows, but while CPU usage dipped, the latency stayed high—a surface-level fix that didn't do squat. I went into the BIOS and pushed the primary timings from 40-40-40-77 down to 36-36-36-72, while bumping voltage from 1.1V to 1.25V. AIDA64 showed latency drop from 85ns to 65-70ns, and the combat finally felt fluid. I tried 32-32-32 and immediately got a BSOD; loosening tRAS to 76 was the only way to stay stable. RAM temps are 45-52℃ and VRMs are 55-60℃. Frame time analysis confirms the drops are gone, staying at 9-13ms.
