I upgraded to AMD driver 20.7.2 and while I now can get it to run with my RX580's and Vega56, I'm having the exact same problem as batsonxl - if I have straps set to 1 or whichever straps I'd previously used, the whole rig crashes the moment it tries to applies the straps. If I set it to 0, it will start up and run, but probably with around a 35% reduction in hashrate as the straps aren't being applied. Hopefully straps can get working again for AMD's? Thanks
