My first rig is composed of 4 Vegas (64*2, 56*2), and perfectly working with Claymore (from nanopool). Now im building my 2nd rig with 12 RX 580 and finally able to work! However im getting this error and couldnt figure out what happened.

What I did:
Windows 10 up to date.
AMD Blockchain software successfully installed
Virtual Memory updated to 16GB

What clock settings are you using for your V56s? Are you mining Ethereum?

All are in stock. I didnt do any modification yet. As i want them to work first. Perhaps claymore is just not ok with 12 gpus?
