Does syncing FCLK fix frame drops on MSI B650M Gaming Plus?
Having my FPS tank from 240 to 110 during a teamfight is a complete disaster in a competitive match. The MSI B650M GAMING PLUS WIFI had a 200MHz mismatch between the default FCLK and the memory controller, creating micro-queuing delays. I tried the 'Low Latency Mode' in the drivers, but it just made my mouse feel floaty while the frame time still jumped between 15-40ms—total waste of time. I went into the BIOS and locked the FCLK at 2000MHz while enabling the XMP profile. Checking RTSS, my 1% lows jumped from 110 to 185 FPS, and the 'slideshow' effect vanished. I tried pushing it to 2133MHz at first, but the system wouldn't even POST. I had to back down to 2000MHz and nudge the SoC voltage to 1.15V for stability. CPU temps are 62-68℃ and VRMs are 55-61℃. I exported the frame time logs to verify everything, with fans humming along at 1400-1600RPM.
