Since with the new RX 500 series, you must have installed latest drivers to be able to run and mine correctly. But there is a problem, beside of Linux there is (was) no way to run more than five cards with one rig, the 6th or 7th card were not recognized at all because of some driver bug.
After many tests, someone tried a strange mix of drivers and for some reason it worked.
So If you are struggling running 6 cards at once here is what you should do to fix it

2 Extract Drivers
- Run 17.5.1 driver file and extract the files, skip the installation
