Claymore, I know I may be asking a lot here, but just in case it's not too much additional effort... The Radeon Pro Duo is technically Polaris. It's got Samsung Mem (16GB on each GPU); two WX7100s/RX 580s.
Was hoping your straps would work without having to try bios flashing the master and slave gpu bioses, but the miner instaquits it I run as admin with -strap 1. If I don't run as admin, miner runs fine, but with no straps. Believe it's related to errors reading the boot configuration data.
Driver is latest Pro Driver, 19.Q1.2. Have used the AMDMemTweak CLI from Eliovp, and it works, but would like to try the straps you are using in your exe. Others messing with AMD workstation gpus may get some good here too! Thanks!
Check the log file for details. Or create "config.txt" file with options and right-click EthDcrMiner64.exe and select "run as admin", it must work. Or start "cmd.exe" as admin and start miner from it to see what happens, miner cannot close without any messages.
Claymore, many thanks! it worked with the config.txt file, just not the start.bat file.
