How to fix signal sync issues on the Biostar B650MT?

Those horizontal tears across the screen were absolutely killing my immersion, especially during intense fights. Digging into the data, the Biostar B650MT's output signal was hitting a 12 - 22ms sync delay at high refresh rates, meaning the GPU frames and monitor cycles were totally out of whack. My first instinct was to enable V-Sync in-game, but that spiked my input lag to over 45ms—it felt like I was wading through mud. That failure proved the issue was deeper in the hardware link. I flashed the latest AMD chipset drivers and switched the PCIe link mode to 'Enhanced Sync' in the BIOS. Using a frame time analyzer, I saw the sync error shrink from 8 - 15ms down to a tight 2 - 4ms window, and the tearing vanished instantly. Before the driver update, I tried capping the refresh rate at 60Hz; the tearing stopped, but the fluidity was gone, which was a compromise I just couldn't live with. Core temps stayed between 48 - 55℃. After a 3-hour torture test, the sync issues are dead, and RAM temps are holding at 48 - 55℃.
