Why is Afterburner not working with my RX 570?

[tf2addict]

Sapphire PULSE RX 570 4GB Hynix

The only thing I can control in Afterburner is the fan speed.  The core and memory clock sliders are greyed out and are set to zero.  I can slide them to other values but when I click apply they reset to zero.  The other sliders (power limit, temp limit, core voltage) cannot be used.

This happens whether or not Wattman is installed.  What could the problem possibly be?  I've tried the current AMD driver 17.7.4 as well as older versions and Afterburner 4.3 and 4.4 beta.

I should note that TRIXX is not working right either so it's not an Afterburner problem per se.  I just don't know what the deal is here.
