Miner turns on but can't start

1
I have rig of 6 cards 1060. Now I’m trying to mine with 2 of them. But everytime when new job comes it has difficulty 1 and then nothing.

grin-miner.toml

[[mining.miner_plugin_config]]
plugin_name = "cuckaroo_cuda_29" 
[mining.miner_plugin_config.parameters]
device = 0
cpuload = 0

[[mining.miner_plugin_config]]
plugin_name = "cuckaroo_cuda_29" 
[mining.miner_plugin_config.parameters]
device = 1
cpuload = 0

Please help me.

This is how grin-miner.log looks like:
