Hi friends, i'm using nvidia 8Gb and optiminer version 1.2.0 running on windows, at first it runs smoothly but miner always crashes after few minutes. I've tried to set the intensity, even the underclock setting, and the temperature is maintained. Is there any solution for setting?
Seems, strange ..
did you set 8GB of virtual memory on windows of each card ?
I have set windows virtual memory for 32000 (2xRAM 16Gb).

I used nvidia 1070 8Gb x 2. Optiminer error is always showing "share submission failed : low difficulty share of ........ ".
