Cuda error

Hi All,
My namd-2.8 was working until I upgraded the drivers to 302.17. Now namd
complains:
FATAL ERROR: CUDA error on Pe 0 (node3 device 0): All CUDA devices are in
prohibited mode, of compute capability 1.0, or otherwise unusable.

my gpu's seem to be configured correctly (all three look like):

Other codes find and (still) run on the gpu but the new drivers seem to
give a problem with namd. The compute mode is default since the scheduler
takes care of managing the gpus. Any idea why namd is complaining about the
"compute capability"?

many thanks!
Eddie
