Is my Crucial DDR4 3200 causing lag in Tekken 8 because the frequency is too low? Should I enable XMP?

I finally found the culprit! This kit had been running at the base 2133MHz frequency this whole time—what a complete waste of hardware. That missing bandwidth caused a 10-15ms instruction delay during physics collisions, making my moves feel sluggish and unresponsive. I tried switching to the 'Ultimate Performance' power plan in Windows, but that only gave me a measly 4 FPS boost and didn't touch the core stuttering. I rebooted, entered the BIOS, and loaded the XMP profile to hit 3200MHz. CPU-Z confirmed the jump immediately, and my minimum FPS leaped from 55 to 88. The smoothness is honestly exhilarating. I did have a scare where the system wouldn't POST after the first XMP attempt, but a quick reseat of the sticks and cleaning the gold contacts fixed it. Temps are 40-46℃ at 1.35V. In-game monitors show the frame generation is finally stable.
