I can see your core clock is 1380 Mhz but your mem clock is only 300. I don't know what you are mining but you should start with a clock of around 1150 and increase your mem clock. Start at 1800 and increase with small increments.

Ok nvm i see its running at 1900. What drivers are you using?

Radeon Adrenalin 17.12.1 - that setting is dynamic, so it should adjust according to a load.

Do You have any ideas why the hashrate is lower?

Have you set the GPU to Compute mode in the AMD Radeon Settings?

I have missed that, thanks a lot - hashrate is now 23,6 MH/s!

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

GPU-Z export: https://imgur.com/a/kWg2I Stock GPU settings: https://imgur.com/a/2ajlQ OC GPU settings: https://imgur.com/a/z6rA2

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 :-)
