all versions of phoenix miner detect my RX 590 (detected correctly on Windows, in the driver and in MSI afterburner) as an RX 5700XT so there is some kind of problem that makes the card crash very 2 days or so and having issues with the core speed.
The speed drops below 1000mhz and never goes up but MSI AB applies correctly the voltage.
Any idea?
Which version and where did you download PhoenixMiner?
Which Windows and graphics drivers?
The version from the page 1 on the thread. Oficial.
