ASRock Z370M Pro4 S.T.A.L.K.E.R. 2 Heart of Chornobyl PBO Overclocking for Frequency Limit Maximization
In S.T.A.L.K.E.R. 2 Heart of Chornobyl survival mode my ASRock Z370M Pro4 frequency bottlenecks limited performance. After a 30-minute stress test I entered the BIOS frequency adjustment menu and enabled PBO optimization confirming safe frequency limits with smooth temperature curves. CPU frequency rose from 3.8GHz to 4.5GHz delivering 20 percent better performance. Memory frequency overclocked from 2650MHz to 3050MHz increasing bandwidth throughput. Graphics card voltage shifted from 1.05V to 1.12V improving stability. BIOS changes were backed up to prevent loss and allow quick recovery after reset. Cooling system tweaks anchored temperatures at 73.5 degrees while fan noise decreased. System boot time shortened and background services cleared out. On-screen frame counts tightened from plus or minus 18 frames to plus or minus 5 frames. PBO optimization verified safe frequency limits and boosted the immersive gameplay feel.
