HOW TO RUN 6 OR MORE RX 570 / RX 580 GPUS ON WINDOWS 10

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.

3. Installing mixed drivers
   Go to “Device Manager“
   Right click on any GPU from “Display Adapter” tab then click on “Update Driver Software“

   Wait for a few seconds to install the driver
   If you get a Windows security warning just click on “Install this drivers software anyway“
   That’s it, restart your RIG and then check again Device Manager,you will see all GPUs installed
