I'm getting signal jitter and frame drops in Remnant 2 during heavy combat with Crucial DDR5 4800. Do I need to tune timings?

While dodging through the realms, I kept getting these micro-stutters that completely broke the flow of combat. The Crucial DDR5 4800 controller was hitting a 1.5-2.1ns sync deviation under high concurrency, causing frame times to bounce wildly between 12ms and 35ms. I tried enabling every 'acceleration' toggle in the drivers, but that just caused the game to hang on the loading screen—what a nightmare. I went into the BIOS and tightened the primary timings from 40-40-40 down to 36-38-38, and pushed the VDD voltage from 1.1V to 1.25V. In AIDA64, the latency dropped from 92ns to 76ns, and the combat finally felt fluid. I tried pushing for even tighter timings, but the system randomly rebooted twice until I loosened tRAS to 80. Temps are sitting between 48-54℃. I switched the memory profile to 'High Performance' in the control software, and it's finally playable, though it's still a bit temperamental.
