Does RX 460-470 have a native support?
No, I don't have these cards, so you can try different "-h" values to find best speed and share best values here.
What about RX 480 hashrate?
And could you tell me please, are you going to add support for AEON in your CPU and GPU miners?
AEON is attractive now ;-)
I get 640 H/s stable ( 640,640,641,639,640,640,640,642 etc) on my 8 gb XFX reference amd 480.
-h count of 1024. I made an excel sheet and did the +/- 32 h count up and down about 10 increments and 1024 gave the most.
