So I just started mining Ether yesterday, and I was using my fury x when I remembered that I have an old r9 270. I put it in and without changing anything, I was only getting 1.5 mh/s. After installing Radeon 15.12, I managed to get it to 6mh/s, still no where near the 13-15 mh/s that people are reporting. And lastly, when I stopped mining this morning to give the GPU a short break, its hashrate when BACK DOWN to 1.5mh/s. I am using EthDcrMiner64 to mine in a pool.
Update:
I plugged my monitor into the 270 instead of the fury, and the hashrate is back up to 6 mh/s, but this is still half of what most 270 owners report.
