How to stabilize clock speeds on Gainward RTX 5080 Storm OC?
Just as a stunning snow mountain came into view, my FPS plummeted from 140 to 80. Honestly, I was almost excited because it gave me a reason to mess with the 5080's voltage curve. The Gainward RTX 5080 Storm OC was suffering from transient power spikes, causing the core clock to bounce between 2.1-2.6GHz, which made the frame delivery inconsistent. I tried 'Maximum Performance' mode in the driver, but that just pushed temps to 85℃ without solving the instability. I switched to a manual undervolt using Afterburner, locking the voltage at 0.95V and the core clock at a steady 2.45GHz. Monitoring showed the frame time variance collapsed to a tight 7-9ms, and the drops vanished. I actually tried locking it at 2.6GHz first, but the driver crashed immediately until I bumped the voltage to 0.98V. Core temps now sit comfortably at 68-74℃, and frame times are locked at 7-9ms.
