Far Cry 7 is dropping frames in heavy fights with my G.Skill Trident Z5 6400 due to FCLK desync; should I sync it manually?

When the jungle explosions hit the screen, there's nothing like that feeling of absolute fluidity when the memory is perfectly synced. The G.Skill Trident Z5 DDR5 6400 has incredibly tight default timings, but the FCLK was jumping randomly between 2000-2133MHz, causing frame times to bounce between 11-25ms. I tried the 'one-click' EXPO profile in BIOS, but the system just hard-locked after 15 minutes of gameplay. That simple fix is clearly a myth on DDR5 platforms. I manually locked the FCLK at 2000MHz and bumped the memory voltage to 1.4V to ensure a strict 1:1 sync mode. Checking RivaTuner, the frame rate swing narrowed from 70-95fps to a much tighter 85-92fps. I did see some minor memory parity errors at first, but loosening the tRAS to 88 cycles killed those off completely. CPU temps are holding at 65-72℃ and the RAM is at 52-58℃. The performance panel confirms sync mode is active, and everything feels rock solid now.
