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.
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 have vega 64 and I had same problem, rig was stable for 6 to 18 hours and then crash, first tought it was power issue and removed one card from rig but same problem,managed to find a flaky card (which wasn't flaky on v7 ,maybe it is not flaky) removed it and again crash; lowered the intensity to 116, after 24 hours so far so good
