No one advicing to use the latest drivers? I have had a ton of issues with the blockchain drivers, the new adrenaline drivers are night and day in terms of stability for me and my rigs.

I run 8x580's, OC and undervolt and each of my Z270-A motherboards, a single 1000w psu and they are rock solid.

Do yourself the favor, completely reinstall Windows 10 1709, DDU the drivers and install latest adrenaline driver, and then enjoy.

The chances of a faulty card on stock settings is very minimal, more likely to be a riser issue in that case.
