IMO drivers no matter.

This miner obviously needs an urgent update!

@Claymore: any chance you plan to give it a boost, at least your recent wrapper, speed/stability improvements also highly appreciated, but less critical.
-r 1 (machine reboot instead of miner restart) and rx400 temps for Remote Manager at least. (GPU turnin on/off is needed as well)
Also if better detection of "low difficulty shares" is possible...
