Using voltage offsets and PBO to eliminate input latency
Based on log 2026-DP-11 on Windows 11 24H2, I ran OCCT stress tests. I started with a basic all-core overclock, but the system BSOD'd after 15 minutes—the feeling of spending hours only to make it worse was devastating. I pivoted and went into BIOS -> Advanced Voltage Control, set the core voltage offset to -0.070V, and enabled PBO (Precision Boost Overdrive). CPU-Z showed all-core clocks stabilizing between 5.2GHz - 5.4GHz, and the input lag vanished. However, since the AK620 is air-cooled, package temps hit 92℃ under extreme load, triggering a slight throttle. I can't maintain absolute max clocks forever due to the thermal wall.
