6xR9 380 periodically resets GPU0 speed, and the miner errors appear non-existent cards, with which it can be connected?
It's a bug, will be fixed in next update. Divide card number by 2.
How soon will be next update ?
Do you want more speed?
The R9 Nanos uses HBM - high bandwidth memory - and have the best improvement vs all my other types of cards.
v6 has tremendously taken advantage of this features in R9 series that the card posting nearly 200 H/s even better past 180s H/s of 390s.
RX480s however at best posting 130-140s H/s -- could you do your magic on the RX cards?
