Hi there!

I have a dozen of Radeon Pro Duo 32 gb. I didn't make any boost yet. With the blockchain driver it is mining 48 mhs each graphics card (2 gpu per card, 24 mhs each gpu).

I know that there should be an option to overclock it. I am not able to do that. Maybe there is somebody who tried that? In msi afterburner I am not able to boost it. The graphics card must be locked. I don't know how to unlock that. In the driver there isn't any wattman also. No option to change it.

So, did someone try that?
I've heard that someone is getting 59 mhs per card but I couldn't find any insight on that.

If someone can help me with this, I am glad to send some tips.

I remember that I have seen a post on anorak.tech about this.  Unfortunately their website is not working...

I guess I have seen it. It appears on search on google but the page doesn't open

i have one at work and i used in the past to mine etheruim at +31 per gpu. +62mhs. the trick was to install driver 16.3.2

Really? Are you sure it is Radeon Pro Duo Polaris? 32 GB? https://www.amd.com/en/products/professional-graphics/radeon-pro-duo-polaris

If this is the card you used and I can mine 61 mhs with it. I owe you

After Installing the amd blockchain driver manually (device manager than browse in the computer the install file), I managed to overclock it in msi a bit.

Now I get 52,5 mhs per graphics card. I don't want to get into bios because I don't know what to change there. It is a new gpu

One more update for whom is interested:
It makes 1350 h/s for Monero without overclock.

So these can mine as much as the Titan Vs?
They cost as much as a higher priced 1080ti at $650-720 but they get 54Mh/s using the Ethenlargementpill

If you have a dozen of them then they just might match one FPGA card. ;D

But I think if you do bios mod it you could achieve the 62Mh/s Etherion mentioned.

Not impressive compared to the Rx Vegas series which do about 1800-1900 h/s with stock settings. Anyway I think this card is more efficient on mining Ethereum rather than Monero.

By the way mining is in "quiet" mode from some months now and I think smart persons are the ones who are mining and believing in a future glorious day when price of bitcoin will be 100.000 dollars.

yes radeon vega is better for cryptonight because  both gpu have simmilar electricity power but vega will generate more hashrate then radeon pro 2. Iam waiting for vega navi to be release , anyone know when its?

There's got to be a way to squeeze more performance out of these cards than that.

Pros: They're binned chips with great power efficiency, samsung memory, etc. with extra memory, 16GB per gpu.

Drawbacks:

• The memory is ECC, which will run slower than normal VRAM. Perhaps this can be turned off.
• Heat; one reference fan to cool two chips isn't great.
• Inaccessibility: the price tag on these cards made them inaccessible to the normal miner. However, the recent drop to $450 made them an interesting play.
• Along with the accessibility issue of course is optimization. No one has put the work in on bios tweaking for these because hardly anyone uses them. Assuming someone ever does, I wouldn't be surprised to see these beauts go above 2k on CN heavy algos.
• Same memory bus width... in spite of the greater memory size, the bus width is pretty much the same as two 580's.
• Drivers; oc'ing these guys is hard. Tweaks really only practical through bios flashing, OC'ing can only really work with confusing, manual tweaks on dated drivers.

I'll keep tabs on this thread for any changes and will post if I make any progress on these.

32GB of Ram each, these cards would kill it in mining CN-heavy

Maybe... the Vega FE, which has 16 GB HBM2, definitely kills it. But HBM2 memory bandwidth is significantly greater. For a Vega FE you've got 64 compute units with ~484 GB/s mem bandwidth, while with the pro duo you've got 36 Compute cores and 224 GB/s memory bandwidth per gpu (albeit, that spec bandwidth is based on low mem clocks). Or in other words, total of 72 Compute cores and 448 GB/s mem bandwidth, although I'm pretty confident you could get the mem bandwidth close to the FE with the right clocking.

So yeah, more compute power but less mem throughput... which I'm pretty sure is what bottlenecks polaris cards on CN. Regardless, one would think that you could at least get the pro duo to 2x580 8GB status, which would mean ~ 2200-2400 H/s on CN heavy... but haven't seen any data/tests on the card for this anywhere that I've looked.
