Version 5 is much better in performance in fact now uses 99% of all 1080i video cards compared to version 4 that used 99% only from the first and 90% from the others .. but after about 30 minutes of operation freezes without any message .. I was forced to put back the version 4 .. to anyone else from the same problem under Windows 10?
Maybe you can check your overclocked setting or cable connections?
I have experienced same issues with ewbf before. I fixed it by replacing my USB raiser cables. Usually freezing on high utilization is a sign of bad overclocking or unstable cable (USB raiser or power) connections.
BTW, could anyone tell me should I switch from ewbf to bminer or not? I have been using ewbf for a while. Is bminer faster?
