I guess its good if you are in Europe and pay high electricity rates but its only 33% more efficient then the highly inefficient 7970/280X cards.

And with the high cost, doesn't seem like its worth the upgrade. I was expecting 30MH/s and using 100 Watts. Maybe it will be possible with a bios hack or with the 470/1060

But this is like having an Antminer S2 and upgrading to an Antminer S3, not really that much efficient.

7970 was doing 24 mhs, or even more with different bios, and only pulling 175-180

Well at least it sounds like this issue is getting AMD's attention, but the solution sounds like a they will just try to throttle the card below the "danger zone". Bad design out of the gate here on this one. I hope the aftermarket cards address this and they start to appear soon.

Just to be clear, I have many of these in Rigs with USB powered risers, and have no issues. I am getting 27.5MHs per card, and they pull ~155w, this is vastly better than I get with my 390's in terms of MH/s per Watt. The blowers on these aren't bad at all, in fact quieter than most of my aftermarket 390's and run about 8c cooler. It took me about 20 hours to figure out the ideal config to get those numbers, but the RX 480 is definitely a winner.

(USB Risers) are the best!

You mean fan turned all the way up? Yeah if it is at the maximum speed 100% it is at 65 dec, now is it actually going to be running like that while mining? I don't think so.

Where I live everyday is 30 35 Cesius ambience temperature, if I put the card in 70 ~80% (fan speed) the temperature will stay at 80-88C. In this average my cards will be fucked up in a matter of months.... And even 70~80 Fan speed still too loud, compared to Dual Fans non-reference models.(xfn/gigabyte/sapphire/asus etc...)
PS: With 30~35 ambience temperature, the dual fans cards stay between 65 70C.

Would it be ok to make 6 card rigs? Or 5?

I don't see why not. I can fit 4 comfortably in a 1k PSU. Also, my fans run at 2200-2600 rpm which sound lower than what's in the video, they are not loud at all. I've found though if the Wattman utility ever crashes, you have to remove all drivers and software and reinstall or it will not take the -15% power that I set the GPUs at to get the cool running.

RX480 65 db vs 290 its 69 db. So yeah, more than half as loud. ( +3 db is double amount of sound ).

What is the total hash and the total power consumption on the wall? How many 480 do you have in one rig?

I have 3 x 4 card rigs, each does 110 Mh/s at 775 watts at the wall (including CPU/Mobo etc).

During stress test that measured 90W from pci-e, it's not difficult to believe in a motherboard literally burning..

That being said, AMD has announced a new driver that should fix the problem.

90W is a lot. If you use 6 480X for mining without extra +12V power supply to the PCIE slots, it will burn out.

Or use powered risers?

You need very high quality risers. Most risers are not built to supply 90W of power. You also need good PSU cables.

Wow by reading all this, I feel lucky that I miss the boat buying rx 480. They were OOS really fast.

reference 480 is bad card for mining. i can't believe AMD failed it so much on so many points

To be fair AMD's main focus isn't just mining. They aren't Bitmain and I believe that their main concern is fps rather than hash rate. Just like people are not going to invest in creating an asic for an algo that may be gone in six month AMD is not going to invest heavily into optimizing their video cards to mine coins.

I believe is also not for everyday gaming. The Ethereum mining does not stress the GPU like 3D marks.

It probably was a cost saving measure in manufacturing where this design would cut costs by some tiny amount and thats why you end up with a poor design.

Quote

The problem is two fold:

1- AMD soldered the RAM vrm's to pull its power exclusively from the pci-e, without touching the 6 pin.
2- AMD hard soldered two pci-e power lanes to the GPU. So instead of the gpu pulling all its power from the 6 pin, its also pulling from pci-e.

I think you could also add the memory they use is clocked at a high speed and most likely running inefficient, pulling more power. So instead using a wider bus on the interface they speed up the traffic. Fine but then it seems they looked for an additional corner to cut to save costs, its like they said oh lets use 6 pin to save that fraction of a penny in manufacturing and then pull the rest from the mobo.

The electrical engineering guys want to build things right to the proper specs but then you have these assholes that look for corners to cut to increase profit.

The memory are running too fast. That indicates they have high voltages. So the power consumption is high.

the 6 PIN was a marketing play, really. Hence the "disguised" extra ground pin which makes it effectively an 8 Pin. They knew they needed the power.

Not sharing the gddr5 load between the pci-e and 6 pin was one mistake. The other was having two gpu phases pull power from the pci-e.

They screwed up, honestly.
