With a 280x and a 290x I'm mining about 1 ETH per day. It still amazes me to see the huge swings in hashrates on both cards.
All my cards are pretty steady with their hashrate.
I'm watching it poolside, the 290x has been as low at 10M and as high as 60M. On the miner they are steady. I just let them run!!
Ahh, yeah poolside it is just an estimate. Are you using ethproxy? It may help even things out a bit.
No, only have 2 miners so I'm using just ETHMINER
im on with 2 sapphire dualx 270x on EthMiner too. Avg 25-30 Mh/s. The nano shows extreme hi/lows as well but averages about right with what the miner says on PC. Im having a tough time keeping the ETH.exe flowing, it runs fine for a bit then stalls out with no updating. EthMiner keeps running and pool rate shows mining and is paying out. But whats up with the eth.exe stopping all the time? This last stall from a restart has been 2 hours with no eth.exe work flow, any idea?
