Freeze when using systemd #141

Closed burner1024 closed 2 years ago

From cmd, undervolt appears to be working correctly:

$ sudo undervolt --gpu -100 --core -100 --cache -100 --uncore -100 --analogio -100
$ sudo undervolt --read
temperature target: -25 (75C)
core: -99.61 mV
gpu: -99.61 mV
cache: -99.61 mV
uncore: -99.61 mV
analogio: -99.61 mV
powerlimit: 25.0W (short: 0.00244140625s - disabled) / 25.0W (long: 28.0s - enabled)

But when I put it into a systemd unit as described in readme, and restart the service, the system freezes immediately. Any tips?

probably your offsets are too aggressive and are too much when your system is under load (during startup)- try reducing them a bit and testing with some load
