Is there a way to lower input lag on my 7800X3D for better parrying in Phantom Blade Zero using FCLK?

That feeling of perfect sync between your fingers and the screen should be a given on a 7800X3D, but I was getting this weird, floaty lag. LatencyMon showed DPC latency jumping between 1.2-2.8ms, which is a nightmare for a high-speed action game. I tried killing every background process in Windows, but it only improved things by maybe 2%—hardly worth the effort. I went into the BIOS, enabled the EXPO profile, and forced the FCLK from 2000MHz to 2133MHz, while bumping memory voltage to 1.35V. In AIDA64, latency dropped from 68-74ns to 62-65ns, and the parry timing suddenly felt sharp again. I tried pushing it to 2200MHz, but the system started throwing memory errors left and right, so I backed off to 2133MHz for stability. CPU is at 58-64℃ and RAM is 46-52℃. The input response is finally where it needs to be.
