Hi, i have tried mining Ethereum on my Sapphire RX470 4GB NITRO+ and i am getting only 17 MH/s. I tried to overclock a bit, but i will not get above 18 MH/s.. I have Radeon Software Version 17.12.1 and i mine using Claymore 10.5 (tried also Genoil v1.1.7). I have WIN10 64bit.

Here is log (stock gpu settings) from claymore: http://m.uploadedit.com/bbtc/1516640635440.txt and overclocked gpu log: http://m.uploadedit.com/bbtc/1516640895900.txt

My card should have about 22MH/s out-of-box.

Do You have any ideas why the hashrate is lower? Thank You for any advices :-)
