Tried diffrent drivers on my R9 Nano. No "asm" so no speed update... Funny that 290 and 7950 work just great

As mentioned above, use 16.3.2 with fijis.

You get interessting result with this driver on R9 Fury family ?
I got 9 x R9 Fury something like 330-370 H/s (-45% power limit)
With -asm 0 -a 2 parameters.

400@-96mv with 16.3.2 lots of nanos, pro duos...

I can confirm that the Pro Duo's work with the 16.3.2 driver and 11v asm 0.

I am running it at +7.1% and I am getting 420-425 Sol/s per GPU.

You should get almost twice that with a pro duo? People are seeing them figures on a nano.... anyway what did you use to undervolt the pro duo?

per GPU

I did not Undervoltage as I don't pay for power on my workstation :-) But I can only mine 16h out of 24h :-(
