I have been testing the shipment of P102-100 GPU's we recently received, here are the results for our 16 x P102-100 GPU mining system:
ETH - Total Speed: 796.881 Mh/s, Total Shares: 48(3+3+0+5+3+5+2+0+4+4+1+5+4+1+4+4), Rejected: 0(0+0+0+0+0+0+0+0+0+0+0+0+0+0+0+0), Time: 00:04
ETH: GPU0 50.649 Mh/s, GPU1 49.744 Mh/s, GPU2 50.086 Mh/s, GPU3 49.684 Mh/s, GPU4 50.027 Mh/s, GPU5 50.145 Mh/s, GPU6 49.682 Mh/s, GPU7 50.243 Mh/s, GPU8 49.840 Mh/s, GPU9 50.127 Mh/s, GPU10 47.945 Mh/s, GPU11 50.010 Mh/s, GPU12 50.221 Mh/s, GPU13 50.104 Mh/s, GPU14 48.273 Mh/s, GPU15 50.100 Mh/s
OS: EthOS 1.3.1
Miner: Claymore 11.6
Finally we get those information, I also guessed its hashrate should be about 50 mh/s. Btw, have you tested it with other algo, for example mining Monero? One month ago 775$ per card is a good deal, but now it's hard to say as Bitmain's going to release asics miner E3. Even me, I'm going to switch all of my Rx580 rigs to mine Monero in next month. Claymore already added new string for Monero hard fork. Hopefully Ethereum will have some move on it.
