I'd like to share my latest windows clean install adventure:

8x 8MB Rx580's all OC settings the same for each try

Windows 10, build 1703 + 18.3.2 = very good on 1.6.7, good on 1.6.8 (CN-Heavy Hashrate maxes out at 8600 h/s) -Sometimes crashes on algo change, all cards maxes h/s
Clean install of Windows 10, build 1803 + recommended driver 18.6.1 = shit (7600 h/s)
Clean install of Windows Enterprise, build whatever + recommended driver 16.8.1 = somewhat shit (7800 h/s)
Windows Enterprise + 18.3.2 = good (8200 h/s) -> This is what I'm doing right now. Seems to be stable on algo change, although randomly 2-4 cards would hash at shit speeds.

So the newer windows builds are shit, and Adrenalin 18.6.1 is not doing me any favors. Couldn't try 18.5.x with so much downtime biting my ass.
I'm not hashing v8 anymore because I'm losing to much hash with the 18.6.1 drivers, even on clean windows installs.

Anxiously waiting for the new version, I hope Doktor can do his magic once again.

What intensities are you running the cards at?
I just lowered my Vegas from 120 to 112. Not too sure why I thought going higher for v8 was ever going to be a good idea... just followed blindly what was written here as "suggestion".

So far all the Vegas are hashing fine - I isolated my flaky card and run slightly lower clocks and higher voltage on it to be on the safe side. So touch wood, I think I've solved my problems...

I use the default intensities (56) for Rx580. Right now though it began hashing again at 8500, after a 2-3 hours though (it goes for 8200-8250 for quite a while), better late than never, awesome. Sometime 1 or two cards do get stuck at low hashrates, that's quite unpredictable. But ultimately, 18.6.1 is still a bad choice for my mining (Currently 18.3.2 is doing mighty fine) as the max it can go has been 7800 on my rig, even after hours.

I observed my fury cards sometimes getting stuck at lower hashrates, changing worksizes for those cards helped, dunno what your default worksizes are for Rx580 but it helped my furys changing from 16 to 8 and vice versa
