Hi generix,
Thank you so much for your further help, and sorry for this late reply. First, I could turn on the ECC function. Below are the processes I did, provided only for debugging (and avoiding) this issue.
- I tried to disable the persistence mode accordingly using “nvidia-smi -pm 0.” This operation changed the rows of “Persistence Mode” in “nvidia-smi -q” to “Disabled”.
- Without a reboot, I ran “nvidia-smi -g 1 -e 1,” and the “Pending” ECC state changed to “Enabled.”
- After a reboot, “Persistence Mode” changed to “Enabled,” and the current and pending ECC states were “Disabled.”
- As I did not understand when the driver of version 530 was installed (I had installed 525 manually,) I deleted the driver version 530 and then installed version 525 (with “-server”; I did not find the driver without “-server” and “-open” today.)
- Just after installing the driver version 525, the persistence mode was “Disabled.” I turned on the ECC state with “nvidia-smi -g 1(&2) -e 1.”
- After a reboot, I confirmed the current and pending ECC states remained “Enabled.”
- I further installed CUDA 11.8. This installation changed the driver version to 530.
- After a reboot, the persistence mode was turned on. But ECC states remained to be “Enabled.” This could be confirmed both from nvidia-smi and nvidia-settings GUI.
Thank you again for your time and support.
Kai
