My goal is to replace the GTX 1080 Ti in my PC with an RTX 4080 Super. So far my attempts at swapping the 1080Ti to the 4080S have resulted in severe stuttering and visual artefacts, frequent monitor signal losses as well as random shutdowns and BSODs, even under light load. These symptoms have forced me to return the 1080Ti to the assembly, as the stuttering only emerges with the 4080S installed.
With stuttering, I mean drops in framerate that last for 1-5 seconds with intervals of 1-10 seconds. The framerate drops from 100-120Hz to 1-10Hz. The interval and duration between stutters depend on the load somewhat unpredictably. Heavy load induces steady 2 second stutters every 1-2 seconds, while light load induces them more randomly within the duration and interval brackets I first mentioned above.
Monitor signal losses happen many times a minute, and shutdowns often with them. BSODs happen less frequently, but at least once every 15-30 minutes. So far I have seen at least the following codes and drivers(?) mentioned in the BSODs:
