cuLaunchKernel(): the launch timed out and was terminated

this has just started, it seems to be affecting my 3080ti only.

I have two 3090's running as well but they are unaffected by
the cuLaunchKernel error

Any one any Ideas

I think I may have solved it. I had been using a 6pin to 8pin splitter and there may not have
been enough juice going through the lead. Sourced, a couple of proper 8pin leads and all touch wood
seems to be ok.
