Gears 5 is dropping frames during combat on my Galax B760M D4 Wi-Fi White Phantom, can timings fix this?

Whenever I snapped my view between cover, the FPS would dive from 120 to 70 without warning, which completely ruined the game feel. While the White Phantom has decent compatibility, the default timings were causing high latency of 85-95ns during heavy load. I tried 'Game Mode' in the drivers, which lowered CPU usage but did nothing for the latency—I was very skeptical of that 'fix'. I went into the BIOS, dropped the primary timings from 16-20-20-40 to 14-18-18-36, and bumped the DRAM voltage from 1.30V to 1.38V. AIDA64 showed latency plummeting from 88ns to 62-67ns, and the combat fluidity improved massively. I did crash a few times trying 14-14-14, and I had to relax tRAS to 38 to stop the BSODs. RAM is now stable at 42-48℃ and VRMs are at 55-60℃. Frame time analysis shows the drops are gone, though RAM temps can still hit 58-63℃ under peak load.
