I guess I will try that. Restarting computer worked with that blockchain driver I was suggested to try but no difference in mh/s at all.

I will give it a try with that driver, thanks. Also I didn't do any bios mod because I was afraid of making performance worst instead of getting it better.

Edit:
Finally finished installing the drivers with a clear installation. Claymore now "stop working" as soon it detect all 4 GPUs, I guess it might not work because of the R9 series .... I think I will try just the RX 570 alone to see if the driver would make a difference to the mh/s or work.

I was using an older one that worked fine, I tried installing the most recent and it didn't change anything in performance at all. It's a Windows 7 64 bit, I have updated it to a good point but I have automatic update disabled. So in like 7 months it didn't update at all

Could someone help me with a problem? I switched 2 RX 460 for 2 RX 570 and I gained per GPU ONLY 4 MH/s.

The two XFX RX 460 were 4GB only and the new two MSI RX 570 have 8gb and more bit-rate on the top of it. One RX 460 4gb was giving 10mh/s~ with a variation of 100h ( like 10.1mh/s and 9.9mh/s) and now one RX 570 8GB gives 14 MH/s with the same variation.
All GPUs in the rig: 2 R9 380x 8gb ( each gives 28mh/s, 40 computing units detected ) and 2 RX 570 8gb (each gives 14mh/s, 32 computing units detected). So the problem or so I believe is that the RX 570 is under performing for some reason and my commands doesn't have anything restraining performance, because RX 570 has far more computing units AND 4GB extra than one of the old gpu. Could the mix of old and new gpu affect the performance of RX series?

In short:
- switched 2 RX 460 4gb for 2 RX 570 8gb, gained only 8mh/s with that exchange meanwhile an old gpu like R9 380x gives way more mh/s.

I guess I will give it a try, I don't know why I just can't mine ethereum on good servers. coinmine.pl worked for me but they pay like really really slow to the point it was a waste of time and electric bill but other pools I tried for some reason give me that error

Edit:
Same error.
Here is a picture if anyone can help me:
Edit 2:
Managed to get it to work now, but I am getting dag error which I am sure I saw tutorial somewhere, I guess I will finally mine ethereum today
Edit 3:
Fixed dag error too and now there is this error: https://imgur.com/9X5NsTJ
Edit 4:
removing the line " -esm 1" fixed it and now I can mine normally, I hope my wall text of errors and trial help someone in the future

I can't mine on dwarfpool. It gives me http error #52 in Claymore v10 and this is the second pool I attempt to use this software

I have literally put alike a video and it just doesn't work, no matter which region I choose ( EU, US etc ). Any ideas?

Hi, I just started using this version of Claymore and I get an error that doesn't let me mine ETH:

ETH: Received error: {"i":4,"result":null,"error":[24,"unauthorizedworker"]} and then only DCR keeps getting it's share normally. I have registered a worker correctly for both pools (ETH and DCR), any ideas? password is right for both too. ETH start mining normally and then suddenly this happens. I also have allpools set to 1

Also, any chance in the future to allow to mine only DCR for example?
