Figured I'd post some settings I have bee successful running on my 6x mixed vega rig.
I previously ran srb 1.8.0 with amd driver 18.5.1. But after I updated to 1.8.2 my rig just kept crashing and srb stopped running.
So I used windows update and updated everything. And after that I did DDU followed by just installing the graphics driver (19.4.1) and not amd settings++.
Something to keep in mind here, is that PPT is no longer required as I understand.
With ambient temp of around 21c and these settings, my rig is running stable with temps within 50c-55c while fans are running at ~3200rpm / 60%.
I have not been able to check power draw of this rig, but considering the low temps/fan rpm it should be pretty low.
vega56 ~1850 h/s
vega64 ~1950 h/s
At some later point I will test power draw and reapply thermal paste.
OverDriveNtool profiles. ( OverDriveNtool version 2.8.1 beta is needed )
