Still have problem with my rig 6x588 & 1x564.
588 working good but 564 wan't work.
5.1c exclude my 564 card.
After update to 5.2e it see 7 gpus but on 564 card can't generate dag.
After 2 minutes system stop working or rebooting. teamred working good. on 564 generate dag in ~16 seconds.
~2 minutes log.
Create 2 bat files and make -gpus 1,2,3,4 your 8gb cards then 2nd bat file only show -gpus 5 (your rx564) then run seperate should work, delete daglim if doesnt work again give -daglim 4000.
