Miner works 5-6 minutes, then crashes at the same settings with ewbf. Gtx 1080x8

This is most likely due to overclocking. You have to readjust it - zm puts a different load on your GPUs.

but ewbf working with this settings. if I slow down, there is no reason to use dtms

I had to lower my clocks just a little bit but its still faster than ewbf, test it out.
