The RX Vega 56 Owners Thread

I have run the GPU-Z beta on my Vega 56 and it reports HBM2 (Samsung) memory. I understand from the GPU-Z author that this is reliable.

So, it seems that AMD is shipping Vega 56 with Samsung memory for now at least.

Poor Hynix

Awesome

What Revision does the beta report on your card? Mine is C3 according to gpu-z 2.2.0 & the review one's appeared to be Rev 1. Wondering what the difference might be - if any.

Has anyone else come across this at bootup?

I've also been unable to install drivers as it blue screens on me with a atikmdag.sys error which I can't for the life of me fix after spending all day on it!

At the moment I've got a very expensive red paperweight in my computer

Other than faulty, what is your PSU? Definitely seated properly and two separate power cables from PSU to GPU?

I've got a 650W Antec PSU with both cables coming from a different 12V rail. Yeah I tried reseating it with no change.

Bios update mobo?

took long enough but eventually.....

:edit: just doing coupe of benchmarks on r9 290 to see what the difference is for shts n giggles..

Thanks for the suggestion, I've updated to latest version but still crashes out with atikmdag.sys failed.

Anyone tried mining on one yet? just wondered how it stacks up to a 1070.

I get revision C3 on both versions of GPU-Z.

Have you got an old x58 setup? I have the same problem when installing drivers.

Seems there may be an issue with older systems and the Vega cards

https://community.amd.com/thread/219437

After trying pretty much everything I'm returning the card and probably going for a 1070, which suddenly have gone up in price.

Basic Fire Strike Graphics scores on the two Vega 56 BIOS in each Profile (+power limit) using top fan speed and everything else on stock.

LEFT BIOS:
Balanced Profile (+0%): 17576
Turbo Profile (+15%): 17866
Custom Profile (+50%): 18316

RIGHT BIOS:
Balanced Profile (+0%): 17220
Turbo Profile (+15%): 17631
Custom Profile (+50%): 17918

It would certainly seem that the left BIOS is producing higher performance. Judging by the higher temperatures and fan speeds, I would attribute this to the left BIOS running at a higher TDP in all three profiles. We see a similar pattern in the various Vega64 left/right BIOS. I can only hazard a guess at the actual TDP on the two BIOS in the absence of laboratory testing, but I would not be surprised with something like 200W right and 230W left.

So, if you really want to stick with a Vega 56 BIOS rather than flashing to a Vega 64, then at least you have a choice.

That's disappointing if I've formatted my windows install for nothing that will be annoying. I'm running a Z68 chipset, would be interesting to see if others have successfully installed vega on similar?

To get on the Roll of Honour all you have to do is post a pic with your user name on it of your Vega 56.

Hmm, im finding the same thing - trying to install 17.8.2 and getting bluescreen every time.... im also z68.....

Probably all the retail boards are C3 then if it makes any difference!

Very happy with my card anyway. I was worried about the ref cooler but it's fine with a bit of tweakage - currently got my card at 1030mv, +50 power target & 900 hbm

T.Kay · 1 Sep 2017 at 19:26

I just got timespy GPU score: 6978 with stock bios. 2% boost on freq at 1080mv, 50% power limit, 915 memory on wattman.

So.. tried 17.8.1 - same thing, literally no way to install the drivers with this card in - same error as everyone else and also tried 17.8.1

Also using gigabyte ga-z68xp-ud3... with 2500k, unbelievable AMD - guessing this is going back fairly shortly like others in that AMD thread above

Will try and install with my 290 - which i imagine will be fine, appears the minute you swap over to the vega it bluescreens anyway.

Nice - I scored GPU 6907 with my settings, not tried any core clocking yet.
