Some feedback for updated miner:

So far pretty stable. Been running 25 min for now no crashes but lets see if it stays alive for 24h.

6x 1070ti 0-4 gpu OC core: +150 mem: +550. gpu 4 oc core: +50 mem : +500.  gpu 5 oc core: 0 mem: +400 Powerlimit: 95w

Speeds are around 13k-13k5 Sols so big upgrade from optiminer and now all gpus mine with same speeds and no hashrate drops.

Edit: Running  on Ubuntu 16.04
