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.
