I'm still not able to make TBlackMiner work. I've installed the 1.19 from HiveOs, and this is the screenshot of the Miner console.
As you can see is printing multiple time per second the hashrate of each GPU, and still 3 GPU are not recognized. Then they go in timeout and exit, the system freezes, I've to phisically reboot.
All are RX 580. I've no problem with other miners.
https://ibb.co/9VqVY65Are you manually setting your Xintensity? Because 0 (zero) should never be a number you see there.
The only thing I can think of is that your AMD drivers are out of date and the driver isn't registering properly with the miner. I'm not running Rx580s so there isn't much direct help I can provide, I just run a bunch of RDNA2 RX6[8/9]00 with HiveOS AMD drivers - A20.40 (5.11.0701)...
maybe try manually setting {--xintensity -1 --kernel 1} in the extra config arguments section of the miner setup to see if those numbers in the console change..?
