Got my first Radeon Pro Duo in today. After a bit of fiddling, my current sweet spot is at 1050mhz core. It ran up to 1120mhz before crashing, but undervolting wasn't as stable. With -100mv undervolt and 1050mhz core, am quite satisfied with the results.
With claymore v4.1 (ethi 8, dcri 60) I am getting:
ETH - Total Speed: 62.117 Mh/s
ETH: GPU0 30.909 Mh/s, GPU1 31.208 Mh/s
DCR - Total Speed: 1863.518 Mh/s
DCR: GPU0 927.275 Mh/s, GPU1 936.243 Mh/s

So we get to see its efficiency (Watts per Mh/s)
and see its real bang per buck?
It is a 1500EUR card hashing at 2x390(650EUR) speed.
The power consumption is a bit on your side but never getting a 850EUR difference.
And there is allways a problem to resell such expensive gpus for normal money...
I would cry with such performance unless You got it for half price.
It is just my opinion, no offense...
I found the firepro workstation drivers for this card (wasn't immediately obvious where they were, and AMD certainly wasn't making it clear). Looks like clockrates are more stable (no clock throttling at -100mv for reasonabe overclocks) and hashrate ever so slightly higher with these drivers installed.
I suspect GPU #2 is a silicon lottery loser tho on this card. It seems meh at best. Admittedly, the cooling situation could be a lot better; I couldn't mount the radiator pointing upwards, because it wouldn't fit in my desktop case that way (corsair 900d case). I have it venting out the rear, and there is a pretty good "bubble" of hot air back there that's getting sucked back into the case.

It seems like these fiji chips can really pump out the dcr hashes with no loss to ethash if you tune them right.
Would be curious if nano can do the same thing; that's some pretty big mining gains.
It's ~59,7 MH/s @ 1055 MHz.
At 1100 it's 61 MH/s.
At stock clock of 1018 it's ~ 58,5 MH/s
I bought mine used with a custom 240mm radiator so that my card max out at 61 degrees celsius.
I'm planing to buy one more but with the stock radiator. Does anyone here know if it is strong enough to hold the card in the temp limit of 74 degrees @ 1050 MHz?
the sapphire Rx 480 has 256bit memory and it gives 31.1++ MH with moded bios
The RX 480 on the other hand is memory limited, not compute limited, so that comparison really doesn't work.
Fury, Hawaii are obsolete.
It's like they say. If it looks too good to be true, it probably is.
Turns out they're scammers.
On topic, I had to RMA by Pro Duo because it started insta-crashing any machine it was plugged into. New card is SAVAGELY better. Runs -125mv core @ 1080mhz. Silicon lottery won.
Yes, they are expensive for what they are. But sometimes that is only part of the story. Also, RX series cards were still only a glimmer in AMDs eye when the Pro Duo was available.
