GPU-Z under sensors tab shows --0C on GPU temperature, clocks are 0,0 Mhz Other characteristics seems ok.
This is to be expected. The RX500 series are new ASIC's and these third party apps will need to be updated to handle these new products.
Other software like Sapphire TRIXX or MSI Afterburner shows same --C and 0Mhz
Delete all of your third party graphics controllers (trixx, ab, etc)...they conflict with Wattman. Then do a clean install of your graphics drivers.
