Asrock AB350 Pro4: I have the same issue with Nvidia cards and Win 10. Got stuck when installing the 5th card. I even purchased the second board thinking the first one had an issue lol.

Much appreciated if someone comes with a solution

I was running on stock clock.

Hey, thanks! It worked somehow. It fluctuated, but I could reach ~400 H/s. I also tried to OC it using the setting here: http://cryptomining-blog.com/tag/gtx-1070-overclock/ and managed to reach ~460 H/s. I don't know yet if it's stable or not, though. Here's the screenshot:

Greetings,

I'm new to mining. I'm having a problem with the miner (tried both 0.1.0b and 0.2.0b). I'm on Win 10 Pro Anniversary Update (1607) and using Palit GTX1070 Jetstream on stock and could only get max ~390 Sol/s.
I use default setting: miner --server zec-apac.suprnova.cc --user xxx --pass xxx --port 2142 --cuda_devices 0
I tried several drivers: 372.90, 375.63, 376.33, and 378.49. They gave me the same results.
Is this common or is there any workaround?
