Hi guys, I have a mixed rig of an rx580 and 6 1060s. I reverted to win7 because I couldn't mine ETH anymore on my 3gb cards.
After lots of trouble trying to make all 7 cards work on win7 (did a registry tweak I got online), Phoenixminer works but my rx580 gives me 19mhs.
I use the october blockchain driver for win7, since there is no compute option on the latest drivers. Pixel patch applied too.
Any help bois?
Also, msi afterburner wont let me overclock my ATI memory, altho it should give me about 30mhs as it is.
And Claymore crashes on ATI with ntdll.dll issue.

Use the robinh00d drivers
