Stabilizing Vcore voltage for Zotac RTX 2060 Super in Hellblade II
Walking through those oppressive hallucination scenes, my frames suddenly plummeted from 60 to 20 FPS. It was a total performance dive. I found that the Zotac RTX 2060 Super-8GD6's auto-voltage was bouncing between 0.85V and 1.05V under heavy rendering, causing the core clock to tank. I tried 'Ultimate Performance' mode in Windows, but that actually made the voltage swings worse—I was being way too naive. I opened MSI Afterburner and manually locked the core voltage to 1.02V while optimizing the frequency-voltage curve. GPU clocks finally stabilized between 1750-1850MHz without those jagged drops. When I first locked the voltage, the core temp spiked to 84℃, so I had to crank the fan curve to 75% to keep it in check. VRM temps now sit at 68-74℃, and core temps are 74-80℃. Switching the control panel to 'Prefer Maximum Performance' finished the job. It's finally smooth, but the fans are definitely louder now.
