Consider solve and will run with that for now.
DDU to clear all driver and flash install 17.4.3 driver - just google you will get it
1. Using 17.4.3, no driver verification.
2. Just using the standard step to mod the bios
3. reboot and run..
Not sure this is normal, when 1st run, I only get 14MH/s and need to use afterburner to crank the core and memory to their normal value. and rerun the miner will get me 28MH/s.
No time to tune it to other setting yet.
Good luck to others and hope you dont need to thru like flash for 10th time then got the "working" version.
Another issue I faced is the RX need to be connected to monitor (I am using 1080ti as primary) and if I either unplug the monitor cable or I choose to configure it as single display instead of extended, it will HANG!
any guru here can help?
