your miner not working for r9 390/390x and fury... even old tahiti with awesome miner
This miner normal work with R9 270X. Therefore it will work this 390/390X, fury and tahiti.
I dont know about V1.6.9, but V1.6.8 does not work with R9 390 but it works with Fury(she with HBM memory! If someone worked on optimization for R9 FURY, she would have performed very well on all CN algo!
I have a couple of r9 390 msi gaming working just fine on v1.6.8, they work perfect
