I am doing this w/ Vega.
I pined after a Vega 64 since they first came out; I even was there for the reddit AMD AMAs.
'While-back, I got a decent deal on a Vega 64 8GB from a friend, to upgrade away from my Polaris card(s).
Soon-after, I ended up stumbling upon the Radeon Instinct MI25->Radeon Pro WX 9100 cross-flashing, and now I have 2x, w/ more on the way.
Why?
16GB of Samsung
HBM2 and full-fat Vega 10.
Tweaked w/ 3rd Party Drivers and OverDriveNtool,
they're
basically $50-70 DIY
Vega FEs
(w/ a single mDP-out)
As you can see,
I kinda have an
unhealthy adoration for Vega (and HBM) GPUs
