Sensor precision calibration during transient voltage drops
In hardware audit 2026-HW-09, the Gainward RTX 5080 Storm OC showed obvious voltage swings during load shifts. AIDA64 showed core voltage jumping between 1.32V and 1.38V, causing sensor readings to freak out with latency spikes from 18ns to 25ns. I went into the BIOS voltage settings and applied a +0.01V offset, then reran the sensor calibration. Under HWMonitor, the voltage finally tightened around 1.35V. The headache is that every driver update wipes this calibration, forcing me to redo this tedious process. It feels like the card's firmware scheduling is flawed; it's accurate for now, but I don't trust it long-term.
