It is mentioned that the Nvidia driver needs to be set to persistence Mode using the command line:

/USR/BIN/NVIDIA-SMI-PM 1

Query whether Nvidia is enabled persistence Mode

#/usr/bin/nvidia-smi-q | Grep-i Persistence

If persistence Mode is enabled, the output is as follows:

Persistence mode:enabled

Nvidia-smi settings persistence Mode fails after each reboot. Arch Linux uses systemd, so in the/etc/systemd/system/multi-user.target.wants directory, create a new Nvidia-pm.service file with the following content:

[Unit] Description=set NVIDIA Persistence Mode to enablewants=syslog.target[service]type=forkingexecstart=/usr/bin/ NVIDIA-SMI-PM 1[install]wantedby=multi-user.target

The

is currently in use for a few days without a freezing situation.
