^^^ Mine does 1k H/s XMR & 31.5 MH/s ETH, you're definitely doing something wrong.
You using SG Miner, or what? I can push my Sapphires rx 470 to 950-960 Kh/s XMR, but they throw a lot of errors, so I keep them at bay with 850-900 Kh/s...I also need to keep them around 100W, so, for me this is the hot spot....
