can it control fan either?
i have got problem in separating one card from other.. i want to enter different wallets
--devices 0,1,2,3,4,5,6 --devices 7
it freezes in miner setting up
You can control temp of the gpus, to avoid and extra hot.
--tstop 75 --tstart 55 --tmode edge --> will mine until GPU arrive to 75C, then will stop until GPU is 55C to continue mining
--tstop 96 --tstart 72 --tmode memory --> will mine until Memory arrive to 96C, then will stop until Memory temp is 72C, but that is only possible for Navi's
If you want to put 2 wallets you should run 2 instances of lolMiner.
I tried this but it doesn't seem to work. I get error
unrecognised option '--tstop'
I am glad that you brought this up because this is something one of my GPU needs because I had to manually disable it because during some times of the day it just overheats way past 80C.
Copy direct from help of the miner. That is able after version 1.17
--tstart arg (=0) Minimal temperature for a GPU to start
in degree C. If set to 0 disables
restart below a fixed temperature.
--tstop arg (=0) Temperature to pause or stop a GPU from
mining in degree C. If set to 0
disables stop above a fixed
temperature.
--tmode arg (=edge) Mode for temperature management.
Use "edge" (default), "junction" or
"memory" to set the mode for
temperature management.
The miner is just no longer spamming to the whole 0.0.0.0 range
