I have 7 R9 Nano; 6 Sapphire and 1 ASUS.

Is your card thermal throttling the clock speed due to high temperature?
Those R9 Nanos can get pretty hot, I have 4 extra fans blowing on them.
My Nano is Powercolor. May be throttling is the reason, I'll check it.
Nice update for Tahiti, but altho on my 290(hawaii) asm kernel works I don't see speed update... any idea what to try?
15.12 everywhere
7950 jumped from 180 to 220 (stock), 290 stay at ~ 250-260
I have a rig with 3x7950 and 1x290 - now they are almost equal in speed :S
Great job as always

:bows:
Currently I use 390 and 390X as Hawaii for tests, I'll check 290 cards soon.
