Why does my Biostar B550MH throttle during explosions in Crysis?
Whenever massive vegetation started blowing up, my CPU clock would suddenly tank from 4.6GHz down to 3.2GHz, and that performance cliff made the game stutter like crazy. The Biostar B550MH's power delivery was lagging by 15-20ms during transient current spikes, causing a brief voltage dip. I first tried enabling 'High Performance' mode in Windows, but that just pushed temps over 90℃ and caused a full system reboot—a total fail that actually made me excited to try a more precise PBO tune. I went into the BIOS, set the Curve Optimizer to a negative 20 offset across all cores, and locked the main clock at 4.4GHz. Using RTSS, I saw the frame times shrink from a messy 12-35ms range down to a tight 8-14ms. It wasn't perfect at first; the system rebooted twice during idle tasks with the -20 offset, so I backed it off to -15 for total stability. CPU temps settled at 72-80℃. After switching the processor scheduling mode in the board's control center, frame times stayed solid at 5.1-6.4ms.
