I have this line in *.bat
EthDcrMiner64.exe -wd 1 -r 1 -epool eth-eu.dwarfpool.com:8008 etc... but it doesn't help, after driver failed, rig keep going calculation low speed (0,5-8mhs on each R9 280x) before it's rebooted myself.
command -r >20 restarts miner, but it still low hashrate and i need reboot.
Assistance please.
The simplest way I've found is to go into device manager, into your GPU, or I guess multiple GPU's (which may get more tedious) and disable, then re-enable them, and everything works. At least for me.
Problem is, my software will run forever once it's gotten started, but often if I have to close it then re-open it, I get the issue of the miner not starting and the driver hanging. So this is what works for me, but I have multiple of the same card and it's an easy-ish process... YMMV...
