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. |

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

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.

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

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. |

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.

"in fact quieter than most" lol lol https://www.youtube.com/watch?v=_kIBj7pnoHk(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. |

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

That is quite good. It seems you can put 6 of them in one rig and can still use the 1000W power supply. |

only the 1070 can do 30MH 100w(110w probably) for now, but it's still to damn expensive on europe |

You won't. And if you are bullish on ETH you would be better off buying coins at this point anyway. Hashrate is rising and ETH is tanking. Rats with shiny new hardware will be jumping ship soon with nowhere to go. No current coin can handle the hash rate that is about to bail on ETH. lol |
