Turn on / off ECC[1]
To Turn off the ECC RAM
# nvidia-smi -g 0 --ecc-config=0 (repeat with -g x for each GPU ID)
To Turn back on ECC RAM
# nvidia-smi -g 0 --ecc-config=1 (repeat with -g x for each GPU ID)
To Reset ECC error[2]
# nvidia-smi -g 0 --reset-ecc-errors=TYPE (0|VOLATILE or 1|AGGREGATE)
Reset GPU
# nvidia-smi -g 0 --gpu-reset
Compute mode
#nvidia-smi -g0 -c <mode number>
