2nd Inno3d 2080ti card just failed this morning. Great white splotches and then card hangs.
First one was coloured speckles all over. Previously, card was running at 93c all the time, with the new one, set-up a very loud fan profile for 73c max. Still failed.
Grr .... going back but the week turn around for new card will be rather annoying. Not sure whether to give up on these now.
Thread updated.
Have you considered trying a different 2080 Ti?
