I tried out the robinh00d blockchain driver for windows 7, it worked fine, it increase the speed for eth from 16mhz to 23mhz.
I also tried to install win 10, it also get the 23mhz, I guess amd decide to fup the win 7 users then...

For who that still wants to use the robinh00d drivers, you will need to restart the computer twice, once you install the driver, then the second after you apply the patch, all of those you can download from the linked post.

Thank you all for the information !

I already tried to remove the driver with this removal tool and use an old one, actually the recomended drive from dell is the version 16.6, I will try the version 17 also. The board is not new, I bouth it used but it have some garantee from the vendor, so there are any way to know if this have an problem ? Its working fine, just the speed seems slow. I have several stuff in this server, I want to have sure on what is going on before upgrading to win 10.

Hi,

I am new to mining so I decide to by and configure an Rx 570 into my existing Dell server : https://ibb.co/eB92qS
But I am noticing that its mining at half speed, not only for etherium but all algs.

This is an Dell Rx 570 video board with 4 gb sansung :

I read everywhere that this board should get etherium arround 25mhz on standard configuration, but I am getting arround 16mhz even with overclock : https://ibb.co/dRTWH7

I already tried :
- Windows 7 with the all last updates.
- Video AMD drive at 18.3.3 : radeon-software-adrenalin-18.3.3-minimalsetup-180319_64bit
- BlockChain driver didnt work on my windows 7, I dont think its working since I saw several other guys with problem with this on win7.
- There is no option to select compute mode on this driver.

I know some ask me to update to win 10, but I really hate that idea in a way that I may sell this card and go for nvidea, so do anyone have any tips or solution ?

Regards,
wagfeliz
