Hi guys, newb here.
I got a 480 8gb and a Vega64 running on 17.10.3
I am keeping my tests as safe as possible, so no bios mods.
I am really baffled by the behavior of my setup over time.
It starts up pretty good for stock and slowly creeps down to a grind.
Also I can't notice a significant difference in hash rate with HBCC on or off, and I have repeated these results with blockchain drivers.

I've searched the thread for a repeat incident, and there has been one, but don't see a reply.
Can anyone shed some light to this freaky behaviour, and a possible workaround?
