Why is my ASRock Z370M Pro4 throttling in Delta Force?
During intense firefights, my frame rate would tank from 80 FPS down to 35 FPS, which completely killed the competitive vibe. The VRM on the ASRock Z370M Pro4 was struggling with modern loads, hitting 82-88℃ and triggering aggressive power limit throttling. I initially tried enabling 'Ultimate Performance' in Windows, but that was a disaster—CPU temps spiked to 95℃, leading to even worse thermal throttling. I started doubting if this old platform could even handle the game. I eventually dove into the BIOS and manually locked PL1 and PL2 power limits to 125W and disabled C-State deep sleep to cut down on wakeup latency. Monitoring via RTSS showed my 1% lows jump from 32 FPS to 58 FPS, making the gameplay feel smooth as butter. I did hit a snag when I first tried bumping the voltage, which caused random BSODs on boot, but everything stabilized once I dialed the Vcore back to 1.22V. VRM temps settled around 75-81℃. AIDA64 stability tests confirmed the clock speeds are now rock steady. Saved all parameters.
