I share with This community the unofficial beta driver
fix for well known DAG drop hashrate problem on RX polaris series RX470/480/570/580.
Nobody knows for sure, if AMD launched an official driver, Or if we will have to use this beta driver forever,What i know is that it works.
For the moment with this driver can be overclocked, via claymore, (advanced user) or use msi afterburner in its latest beta.
1. Download driver.https://www.dropbox.com/s/fknhmqdv0k5v3ic/Drivers_DAG_fix_BETA.zip?dl=0
2. Install driver via Device manager, right click on your card and point to unpacked folder what you previously download from one of the links above.
3. Install well known patcher (atikmdag-patcher), link below.https://www.monitortests.com/atikmdag-patcher-1.4.5.zip
4. Restart your RIG.
5. Overclock, !! WARINING!! For this drivers need msi afterburner 4.4.0 BETA 16. or overclock via claymore,(-cclock 1050,1100,0) (-mclock 1950,2000,2015,....-cvddc 900,950,1000.... please read Readme.txt in claymore for more info.
I test on all RX models, from my experience RX470/480 runs perfect. hashrate performance is restored, tested on win10 annivarsary and claymore 9.8 on all my rigs.
