Thank you and others who mentioned intensity, that's was the cause.
I've set it to -i 22,18,22,22,22 and this resolved my issue.

Hi all, need help with this issue:
Have been mining on 4x1070 for a while ... was good, but after adding another 1060,
miner ccminer (ccminer-1.0-skunk) started crashing without any errors.
After adding 1060 it appeared in Devices List and looked good.
Have Win10 and latest 1070 drivers, ASUS H270-P.

What would you try to resolve this?
Can it be because of lack of power? I've got single 1000W. So i'm trying 4x1070 and 1x1060 on it.

Sending BUY order ... and Waves always tells me 'Error. Order has not been created!'
price is from Sell orders table, and i've got enough ETH ... what's wrong =(

Hey, at what time will it start on August 1 (with Timezone please, UTC)?
Or in other words how much time left?)
