How to fix 7800X3D freezing during Marvel Rivals team fights?
When three or more ultimates hit the screen, the game just froze for about 0.2 seconds. In a competitive shooter, that's basically a death sentence. Even with the 3D V-Cache, I noticed the FCLK at 2000MHz was failing to sync instructions, causing cache latency to swing wildly between 65-88ns. I tried downclocking the RAM to 4800MHz, but my FPS tanked from 165 to 110—absolutely not an option. I flashed the BIOS to AGESA 1.2.0.2 and manually locked FCLK at 2100MHz, while tightening timings from 36-36-36 to 32-38-38. AIDA64 showed latency converging to 62-66ns, and the hitching vanished. I did have some random reboots when pushing 2133MHz until I bumped the SoC voltage to 1.25V. Temps are now 55-64℃ at 4.8GHz. The input lag is finally gone, and it feels incredibly responsive.
