Should I adjust tRFC parameters if Gloway DDR5 6000 causes timing jitter and frame drops in complex Elden Ring dungeons?

Sprinting across the Lands Between was frustrating; my frame rate would suddenly tank from 60 to 35 FPS, which is just jarring. I found that the Gloway Dragon Warrior DDR5 6000 was hitting random latency spikes of 15-22ms under load, killing the CPU cache hit rate. I tried enabling Windows Game Mode and killing all background apps, but the drops happened three times a minute regardless—it was honestly depressing. I went back to the BIOS, crushed the tRFC from 600 down to 520, and bumped the voltage to 1.38V. AIDA64 showed latency tightening from 88ns to 76-82ns, and the combat finally felt fluid again. My first attempt at these timings caused a random reboot during idle, so I had to loosen the timings by two cycles to get it stable. Temps are sitting at 55-62℃. The input lag is gone now, and the game finally feels like it's keeping up with my controller.
