For the moment I am to excited about that 67 Mhsh seeing in the miner and I am staring at the Anydesk from almost half hour now.I don't even have a new motherboard with BAR option to give another boost otherwise I believe I would be seeing 75 Mhsh without problems here.I will update in due time to the new version,no worries about that.
I took this long to write because I am way to excited seeing a miner not crashing with my Powercolor RX 6800 XT-s,every other one has crashed so far.

To be clear, these are not 2% stales, these are 2% invalid shares. Your overclock settings are way too high, they are crashing because they are unstable overclocks. Dial them down to a more sane number.
My stable OC 6800(xt) show 67-68M on TBM.
