Insane, been mining this for 1 hour and found nothing at 4.6m/hash on a R290...
Sounds like we have the same rig and hash rate, I've got the same results - nothing!
I've got about 10k from 2 blocks after pointing 8Mh/s at it for the past hour. It could be variance. What messages are you seeing in the miner?
All I've been seeing is:
Network diff set to 240k
Newblock detected on the network
Network diff set to 241k
Newblock detected on the network
Network diff set to 242k
