Mass Effect: Legendary Edition is dropping frames during combat on my Maxsun B850M WIFI ICE. Will syncing FCLK help?

There's nothing like the feeling of a perfectly synced FCLK making space combat feel fluid. The Maxsun MS-eSport B850M WIFI ICE defaults to 5200MHz RAM, but the FCLK was jumping randomly between 2000 - 2133MHz, causing frame times to swing between 12 - 28ms. I tried just enabling EXPO in the BIOS, but the system hard-locked after 10 minutes of gameplay—clearly not a 'one-click' fix for this platform. I manually locked the FCLK at 2000MHz and tweaked the memory voltage to 1.3V to force a 1:1 sync mode. RivaTuner showed the FPS range tightening from 60 - 85 to a steady 78 - 82. I had some minor memory parity errors at first, but loosening tRFC to 500 cycles stabilized the whole thing. CPU temps stay around 68 - 75℃, and memory is sitting at 58 - 63℃. The sync is finally active, and the micro-stutters are gone.
