You should be able to get support on this but as I have found out its completely volunteer. They have five people working on updating the software and no one on support for their reputed 50,000 users. Only a poorly compiled set of instructions on what to do when it does not work, especially if your are mining anything other than ethereum.
Well I dont hope for support from the ethos team, I got a tip that 6 cards need more than 4gb ram at the start!
Will Check this
I know it probably will not help you, but I have 12 GPU´s running on Ethos with only 4GB of RAM. Were you able to find a solution for that problem you had?
