My miner doesn't support dwarfpool. If you can raise 1 BTC (with a group of people), I will add support for it.
I had some time today to sniff the Dwarfpool connection. Strange that after all this time, they would choose to implement a non standard version of the stratum protocol. So its a Dwarfpool weirdness issue. Regular farm mining through eth-proxy works just fine. Im noticing a 7 Mhs increase in speed and more consistent mining speeds on my AMD rigs.
FAR LESS THAN 1 BTC--
Eth-Proxy works just fine, it is easy to set-up and run, it is free. I don't use Genoil's Ethminer on my AMD rigs, just on my nVidia rigs. All of them connect through Eth-Proxy. I don't use the stratum mode with Genoil's miner, I just let it mine, and it mines just fine. --scryptr
