Hmm try 960mv, my friend that has a Rad 7 50th AE which uses the Vega 20 GPU runs it at 960mv just fine, it could be that Vega 10 aka RX Vega 56 & 64 can work at similar mv setting.
As for Rad 7 prices here in NL the Sapphire is around 774 Euro...
in Germany the Sapphire Rad VII goes for around 703 Euro
But in USA they go for around 699 USD aka 625 Euro...
We always get ripped off it seems...
my reason for going for a Sapphire is due to their supreme customer service & support when of need, i know there are cheaper brands and all, I have the same for EVGA when I buy a GeForce for example, for my experience paying a bit more for a brand that has better services is just worth it, well for me anyways.
Just dunno if I'd go for a Rad 7 just yet, since Navi 20 aka RX 3090 XT is also on the horizon, just going to wait those off and see how they will perform.
Nice card, look slike the reference AMD design, do both Radeon logo's light up? or just the one on the side?
Also don't forget that protection plastic that covers the lgo's lol
