NVIDIA CUDA disable/enable ECC , new commands

In order to query ECC status in CUDA 4.0 (and hopefully the next versions), nvidia-smi works a little bit different:

nvidia-smi -q | grep -e"Ecc Mode" -e"Product" -A2

will give you a excerpt.
Just use nvidia-smi -q for full output

To enable ECC:

nvidia-smi -i 0 -e 1

To disable ECC:

nvidia-smi -i 0 -e 0

Where i is the GPU ID!
