Finished undervolt testing in RDR2 for the 3080 Ti FTW3. I spent another day and a half trying to find the highest stable VRAM frequency, managed to get +1210. at +1220, a small black artifact appeared after ~30 loops in 3DMark Speed Way, while +1210 remained stable for over 60 loops. Recorded through OBS, so the FPS is slightly lower and less stable, but the visible difference is still clear.
Here’s the full FPS comparison table across voltages from 950mV down to 800mV: https://i.imgur.com/xz8zEYf.png
