I'd also like to try these out
I see no dag speed degradation on my R9 Nano, but I see it on the RX580. AMD's new driver does not work here -_-

sgminer crashes  or doesn't start working with the R9 Nano.

Ethminer + patches, I just don't know where to find the correct informations and usually people just ignore questions about these things ... not for the 1st time on bitcointalk.org
