It's win10 Creator which works well with my other rigs, and yeah, Blockchain Driver is very good.

In Device Manager all 8 cards are okay, run Pixel Patch already.

I execute EthDcrMiner64.exe directly, no any .bat file.

Everything is okay except what I mentioned in the first post.

I've just visit this site https://mining.help/ it mentioned about Adrenaline Edition and Crimson Edition. Maybe these drivers are more suitable to my rig. Will try them tonight.
