Lets see, you have the sapphire AIB model, why not use their Trixx software with it.
Wattman has been long known to support (based on Ref design), and using afterburner may conflict.
May be that AMD will add support for AIB cards In wattman (or not), currently the Trixx will also not work on ref card.
The AIB cards are modified (chips, trans., vram, and other components) so may be better to try their software only or just let it run from their vbios settings.
I currently don't have a 5700xt (by Nov. though) and these cards from what I have been reading do not use the conventional OC method (you can search the web), and i'm not talking about the PPT tricks..
Sapphire, at the moment is my choice and I would not be using wattman or afterburner in the current state/build.
And yes there are driver issues, which well...…………….?
