Low hashrate RX470 NITRO+ 4GB

[mrq1199]

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 :-)

Hey I am also facing same issue with Rx 470 4 n 8 GB and Rx 570 4 gb cards on eth Mining on nicehash n etc Mining getting low hash rate

Is this happening globally or I am facing this issue coz of fault in system ??

My Rx 570 4G Elpida is mining at 29Mh/s on HiveOS so it is not a GPU problem.

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?

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

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

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

Modify your bios, you can easily hit 28-29mh/s on your card with even less power consumption.
