Hello all.
I have aproblem with v15.0 of miner software and rx 570 8 GB gpu.
I install the gpu last amd driver and when start to mine the miner show me error 1002 that can not install the driver and my gpu start mining ETH with only 9MH/s. I tried everything: reinstall amd drivers, try different driver version but nothing. Still 9MH/s. The gpu is absolutley new card. My OS is Windows 7 SP1. How can i fix this problem?

Use DDU for clean driver https://www.guru3d.com/files-details/display-driver-uninstaller-download.html

I have 19.5.2 with rx580nitro+/se no soucis https://www.amd.com/en/support/kb/release-notes/rn-rad-win-19-5-2

Thanks for information BUT.....after a few hours of install and uninstall drivers and so on... still NOTHING.
I use DDU and remove all drivers, after that i installed AMD display driver 19.5.2 but only display drivers. After reboot i try again miners but still 9,2 MH/s Tried to press "y" in miners and enabled compute mode. Reboot pc and still the same hashrate. I tried to use other software to enable compute mode and after restar - still 9,2 MH/s. Is there need to install all amd display driver package (software and so on)?
Also is there someone who mining ETH in WINDOWS 7?
How to unlock all potential speed of my gpu under win 7?
EDIT: maybe I must tell that my pc is with older GTX 970 4GB as primary gpu and the new gpu RX570 is as second gpu on my MB.

When you are enabling Compute mode, are your running your batchfile with an elevated command prompt? If not the compute mode won't turn on as it requires administration permissions to make the change.

Just traied: run bat file as admin - still 9,42MH/s. Tried to put "-y 1" options in bat file and run again as admin - still the same......

When DDU, set it to not download drivers automatically. Also set it to delete AMD foders. Also set it to run from Safe mode.... Also instal 20.4.2 and NOT the last driver ( well that depends on what windows version you have )

The bat file is: EthDcrMiner64.exe -epool eth-eu1.nanopool.org:9999 -ewal *******.gpu -epsw x -rxboost 1 -platform 1 -etha 0 -mode 1 -y 1 -strap 1

I tried with and without "-strap" options, also and the default start.bat file - still the same.

When i use DDU was in safe mode, before that deleted the AMD folders and after that i use 19.5.2 version and install the display driver manual - still the same.
I used also and AMD-Compute-Switcher.exe software and it tell me that all of my gpu-s are in compute mode.
When i start the miner it says that all amd gpus are in compute mode but 9,42MH/s@86W power.......
I think there is a problem with my windows 7 or conflict with my default GTX 970 4GB gpu.

install Windows 10 and disable updates
