Unofficial AMD Driver Fix for Ethereum DAG Epoch Released

Ledger Wallet protects your bitcoins

It is not news that AMD is working on a new driver release for their Polaris-based GPU’s that would allow them to solve the mining hashrate dip due to DAG file increase.

Some days ago, an unofficial driver release became available for download. The release is nothing more than AMD’s beta version of the driver. However, it appeared on Bitcointalk forums rather than on AMD’s official website.

As always, there are mixed opinions on this new driver. Some people downloaded and tried it, while others claim that this unofficial release is unsafe. Personally, I’ve tried it on my rig of RX 580/570/560/470s (Sapphire Nitro+ RX 580 4GB, MSI RX 570 4GB, Sapphire Pulse RX 560 4GB and Sapphire Nitro+ Rx 470 4GB) to see what the fuzz is about.

In this article, I’ll try to systematize all the data I was able to gather so far.

Hashrates

Apparently this new driver does affect hashrate positively in some cases. The most positive changes are:

RX 580

  • From 27.2 to 28.1 MH/s
  • From 24.5 to 28 MH/s
  • From 28.5 to 29.6MH/s

RX 480

  • From 20 to 21 MH/s while dual mining ETH and Siacoin.

No change in power usage

RX 470

  • From 25.5 to 27-28 MH/s

Though in this case there were some stability issues. Also, the user who achieved those results was not able to undervolt the card.

Now, many people complain that the driver does not work for them; others claim that they are not able to undervolt the card after upgrading to the new release. I did noticed though that most of the issues are caused by the fact that they do not install the drivers on a freshly installed windows.

To add more, it is a good idea to try the drivers on a freshly installed windows were there are no traces of your wallets or passwords.

Overclocking and Undervolting

Despite popular opinion, this driver does allow you to undervolt your cards. However, it is done differently than when using an official AMD release.

Apparently, you can undervolt the cards by using only the 4.4.0 beta 16 version of afterburner. Some users also noticed that AB does not always reflect voltage changes straight away.

You can also use Claymore v9.8 to overclock your RX 470/480 cards. The tool, however, won’t work with the RX 570/580 ones.

Safety

Some users are concerned about the safety of this new driver. The main concern is the possible presence of backdoors. However, this is a signed AMD driver, which means that in theory it cannot be hacked. The main reason why people panic is because it takes a bit of patience and time to install and configure it properly.  That being said, it is still a good idea to install the driver only if you do pool mining.

Installation

The installation process is rather straightforward and simple.

USE THIS DRIVERS ON YOUR OWN RISK!

Here is a list of the files you’ll need:

1 Download tools

2 Installation

  • Uninstall drivers with DDU in safe mode
  • Install the freshly-downloaded driver through the Device Manager
  • Install the atikmdag patcher
  • Install MSI Afterburner
  • Restart and tweak your rig

Here are my tests for Sapphire Nitro+ RX 580 4GB, MSI RX 570 4GB, Sapphire Pulse RX 560 4GB and Sapphire Nitro+ Rx 470 4GB

After

  • RX 580 24.750 Mh/s (+0.8 Mh/s)
  • RX 570 22.000 Mh/s (+ 0.8 Mh/s)
  • RX 560 11.700 Mh/s (+ 0.4 Mh/s)

In Conclusion

Most people prefer to wait for the official driver release by AMD. While this unofficial beta release is signed by AMD, many community members prefer to play it safe and wait for the driver to appear on AMD website. Both approaches seem equally reasonable, especially considering that soon AMD might post the official version of the driver on their website.

    can you run 12x amd card on windows 10 with this driver?

    • Windows can support 8 GPUs of same model only.

      • Robert Gzivna

        is there any plan for upcoming windows 10 to support more than 8GPU’s? any rumors you heard about it?

  • Jason Dela Cruz

    lol.. i thought we should not trust this driver, but i know ciprian is curious about this and he tried it himself, and after finding out that the fix is real and after few days of safe mining w/out being hacked, he made a tutorial for this 😛

    you all can see the discussion here if by any chance you encounter any of the driver issue.

  • Qri57i

    Hello, tried this fixed few days ago. Got my Asus strixx Rx480 8gb, în dual mine eth dcr, from 27.100 and 700 to 29.4 and 850

  • Ti

    Glad, that you changed your opinion, Ciprian)))

    • Yes Ti, after i tested and verified everything 🙂 now looks good.. thank you! 🙂

  • Grant Southey

    Hi – thanks for this – to make sure I understand – for 6 cards win10, use the 16.. drivers copied into these for mixed drivers?

  • Gonzalo Lester
    • Have you tested it ? Ill test it now..

      • jose

        might we see a big improvement on RX Vega with this new driver?

        • Gonzalo Lester

          Not really, I don’t have Vegas but some users already claiming they didn’t get much improvement..

      • João Rocha

        anyone knows if there will be a linux release for this?

        • Gonzalo Lester

          Yes, AMD confirmed they will release the Linux version (I have some rigs on ethOS)

          • José Antonio Arellano Vega

            But, not exits a unofficial version for linux?

          • Gonzalo Lester

            Not yet..

      • Gonzalo Lester

        Tested on WIN10, back up on MHs.

    • Jason Dela Cruz

      downloaded this, will try tomorrow, as some experienced black / blue screen after the update.. i have more time tomorrow so its better. did you encounter any issue by any chance?

  • Otto Ascaloon Veisenberger

    Hi all! I test the beta driver right now. Before the hashrate is 28.3mhs and after I put the new beta driver is 31.4mhs with sapphire rx580 nitro+. The only problem is I cant undervolt it with AB under 950mv, and they use more power than before. (Now they use 1150w, before when I undervolt it to 850mv they use 930w) Any solution for this? Thanks in advance.

  • Paulo Medronho
    • working on it, will post the article with test results later today.

    Is there anyone who already test it on sapphire rx 570 8gb Nitro+..?
    From stock, i got 20.8 or 21.4 mhs(not fixed)
    But when i installed beta, my hash downgraded to 18.2 or 19.6 (not fixed).. Im using Nicehash btw..

    My rigs:
    Biostar B250 BTC
    Sapphire RX 570 8GB Nitro+ x 6pcs
    Corsair 1200i
    Windows 10 64bit
    GPU Monitor

    My installation procedures:
    – run DDU, restart
    – force shutdown and unplug 5 gpu of 6
    *because my screen completely blank if all gpu intact*
    – turn on and uninstall in safemode windows
    – restart and install the beta program
    * if i shut down before installing the beta and plugs all my gpu, my screen will completely blank again*
    – run atimdag patch, shut down
    – plug all gpu and turn it on again
    – my windows only read 1 normal gpu and 5 not working properly (device manager)
    – i’m running atimdag patch again and restart
    – turn on again, and the condition still same
    – my only solution is using iobit driver, restart
    – and my 6 gpu back to normal
    – i run my mining with Nicehash program, i only got 18 / 19 MHs

    Please CMIIW..

    Hi, do you have the bios mod for sapphire nitro+ rx 580 4gb(Hynix)? I’ve tried to mod the bios myself using the guides on this site and could only get up to 26mhs. Any help would be appreciated!!

  • Sarunas C

    Hi i’m using the unofficial beta driver and just added 5th and 6th sapphire Radeon RX580 Nitro + 8gb to my rig and when i connect everything and start up the rig windows 7 64bit won’t recognize the drivers (i get code 43 error) for the 5th and 6th pci e slot (the new cards worked fine separately) i’m using unofficial beta drivers
    if i try to update the driver separately for 5th card i get blue screen perhaps anyone had such problem and now the solution? Can it be because of windows 7? do i need to install mixed drivers first and update drivers for each card separately?

  • Kristjan Shambar

    after updating the drivers i lost control on Afterburner sliders for core and memory clock. they are just gray and i cant do anything about it. Tried uninstalling, beta versions, reinstalling the drivers but nothing changed.
    Any suggestions?
