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
With -straps 0 do you have accepted shares? Do you have shares that didn't pass check on CPU? ("got incorrect share" message in log file)
About crashing with -straps 1. The miner uses heavily protected custom kernel-mode driver to apply straps and it looks like it's not compatible with new amd gpu drivers. I think the only realistic solution for me is to use some 3rd party driver to apply straps instead of default miner's driver. Still this will require a lot of researching and therefore time.
With -straps 0 yes I get accepted shares, but I would say about 1/2 -2/3 are "incorrect share". I've also tried stock clock settings instead of overclock since my OC's were set using the original straps, but even at stock clocks I still get mostly "incorrect shares" so my effective hash is probably 1/3 of what it used to be. Is this something you think you'll be able to get working, or should I look at using a different miner for my AMD's?
