i got rx6800
no hashrate with ver 5.5C or 5.6a or 5.6b
what is the problem?
Check the post for 5.6b about the drivers that work with it. Under Windows, 5.6b works with Radeon Software 21.4.1, 5.6a works with up to 21.3.2(meaning 21.4.1 breaks it). Linux is another story for the drivers that are supported, but you NEED to install the proper driver version(s) that are compatible.
