currently I´m using a MSI R9 Nano 4GB and a R9 280x 3GB for mining.
In principle I´m pleased with them, hashrate is ~52 MH/s.
But I notice GPU load drops at the Nano, while the 280x runs at 99% of time at 99% load.
So the R9 280x possibly thwartes the Nano? What can I do to avoid this?
When I start (Genoil's) ethminer, it never finds the Nano. Only with -t 2 cl-global-device/platform I get
the miner to run, but it still finds the R9 280x only then. Only because of hashrate I can see
that the Nano will be used also by ethminer.
What can I do that the Nano will be used as primary card? Thanx for a few hints and comments.
