FYI: GROMACS is known to work on IVB-E + K20 hardware, so I'm still
leaning toward thinking that this is either hardware or CUDA software

The next thing I'd have suggested is to plug the card into another
machine and/or plug another card in the machine and try again...

... but if you can't than you'll just have to take my word for it:
Xeon E5-2690 + GTX TITAN -  rnase dodec 181 ns/day; rnase dodec+vsites
382 ns/day. ;)
