I don't think it will massively improve things though. It will be the flagship part with availability, so the new $1k part. Aka same hash as current 7990s just lower power.

Nothing here either, scrambled to get that payment together and nothing back. Its near the end of the day in China, and its taken so long I've now missed it getting in before the weekend. Byebye $400 :/
It's not 6PM in China yet. They can still send it today. We had many times of sending the blades out in 8-10 o'clock in the evening. A lot of blades to be shipped later today.  Thanks of course DHL somehow teleporting my blades around the world in 45 hours + time zone changes. THATS LOGISTICS is a 200w PSU sufficient? is a 200w PSU sufficient for one unit I mean. My math says yes Probably not on the 12V rail though, nor the wiring and everything else required. |

I've set up my blade after reading this nice instruction.
Thanks, dogie.
No problem |

Yay, mine just got out from the plane! Hopefully customs will process it fast... You MUST find a way to stand it up, or put it over a mesh or on feet etc. The bottom of the mining board will get extremely hot, possibly hot enough to set the cardboard on fire.
Actually, is there any other reason for vertical mounting requirement than cooling problems? No |

A little late to start to set it up. It works ok, though the efficiency is a little low, ~94.6%. Vertical mounting is difficult for me now. Sorry for the phone camera.

how to set parameters? Login: gsmline.1234 pass: worker123 poll: stratum.bitcoin.cz: 3333 192.168.1.200:8000 IP :  ? Mask : ? Gateway : ? WEB Port : ? Primary DNS : ? Secondary DNs : ? Ports : ? Server addresses : ? user:pass : ? how can anyone enter one by one and what to type to make it work See setup guide here: https://bitcointalk.org/index.php?topic=205369Start to mine on stratum proxy. Thanks friedcat. Status is as below.  Efficiency seems a little low, anyone know why? PS: PCB's temperature is really high. I can not even touch it.  You need fans! lots of them! See the guide before you damage your baby |

dogie, could you please confirm that this fan is PWM aware? On the site there is no PWM in tech specs, and it have only 3-pin header. Its actually not a PWM fan, I've cheated here. They make 2 versions of the fan: http://www.quietpc.com/rv-120-fan-pwm-switchhttp://www.quietpc.com/rv-120-fan-2000One is PWN, one is not. But because its the same fan and motor, we can buy the PWM version knowing it will still start at very low voltages, and hence is suitable for fan controllers. So we've taken the benefits PWM brings without actually having to pay for it. |

This is pretty cool, dogie. I will add to your whiskey fund when I get mine. So you're in the UK as well? I'm quite curious what will my set-up will end up looking like. I'm thinking it will end up quite messy but hey, it's worth it. I might turn off my GPUs as these are quite noisy. You should put a referral in Amazon, since you are giving some options there. That will add up to your fund. I got this for my 2 blades: http://www.amazon.co.uk/gp/product/B009RMP2VE/ Corsair Builder Series CX 500 Watt ATX/EPS 80 PLUS Bronze Power Supply Unit It's cheap, has good reviews and it should be within its most efficient range with 2 blades at full blast. If I got more equipment I'd add another PSU. These will come at discount with orders over £20: http://www.amazon.co.uk/gp/product/B002QVLBM2 ARCTIC AFACO-120P0-GBA01 F12 PWM 120mm Case Fan http://www.amazon.co.uk/gp/product/B002KTVFTE/ Arctic Cooling Arctic F12 Fan controller (cheap, although the blue led might be annoying if you don't cover it somehow) http://www.amazon.co.uk/gp/product/B006Z8LB6S/ http://www.amazon.co.uk/gp/product/B006Z8LB6S/And I got some more stuff that I might recommend after trying it (cheapo USB-powered wifi bridge and dumb ethernet hub) I just got 1 fan extension cable, not sure whether I will need more. I got an Akasa for under £3. If I need more I will just head to Maplin for a quick fix. (All prices include VAT) I have plenty of scrap cardboard boxes. I will try to use them and cut holes for the fans. Can't justify buying more rubbish unless necessary. Looking forward to receiving them.  Thanks for the donation, and it is 100% to education not booze I've had a bottle of gin on my shelf propping up a computer rather than being drunk for the last year. Yes I am UK Its pretty clean especially for 2 blades, they're much smaller than you think. Added Amazon referral links, was thinking against it as it clouds the purity of the guide but oh well. I also retired my main computer's gpus since these avalons. The pain from additional heat isn't worth the marginal increase in earnings. The F12 fans are pretty crummy, cheap bearings, not great airflow at max and loud for the airflow they do put out. Thanks for the links. Edit: Meant to say, I have that PSU powering 2 at the moment, but because both are on the same molex wire its overspec and I'm trading it in for a 750CXM. |

thanks for nice manual
if one corsair PSU can power 4 blades, then for me it is cheaper to buy 4 IBM notebook type adapters 12v 10A.
4 blades 'safely' if you use two different molex strings and 2 PCI-E connectors. Its still cheaper to buy the PSU because 1) the PSU has a use after and 2) You need a PSU to power those fans! I can power fans from blade itself, or from USB hub. Price wise good PSU cost more in my area and a more work too with cabling, splitting. You have to split and require the adapters as well? |

just out of curiosity, are you planning on having your rig hit ~200C? otherwise, nothing should catch fire, but think about this - when was the last time your read about a building burning down from a server overheating?
Because of something called fire suppression. |

One last question from me:
Which pool should i use?
My 3 options:
-eligius
-slushs pool
-btcguild with pplns
Iam new to asic mining.
Hoping you can help.
Slush's is easiest with stratum proxy as the file is preconfigered for it, btcguild with pps is easiest to set up but has low efficiency. I've not tried others. |

how stable are these machines? how many times do you have to reset them a week?
If temps and power is good - should never reset really. And by reset it just turns itself off and on again and hashes immediately. Could you please measure a temperature of the exhausted air from yellow fan in your setup and at heatsink(by contact)? I'm considering to use a couple of temperature controlled fans like this http://www.arctic.ac/en/p/cooling/case-fans/75/arctic-f-tc.html?c=2183 but it have quite narrow temp band pre-programmed (32-38 C). I don't have a way to measure it. Just stick with normal cheap but powerful fans and a fan controller. |

(most) molex pins are rated at 5A, so for each blade you need minimally two conductors in parallel.
Ideal would be getting some 18ga (I think this is the largest that you can crimp connectors to) wire, some molex connectors, and running "home runs" back to a modular PSU's ports. The PCIe ports have 3 12v pins on them, which gets you in the 80% rule for the connector itself while drawing 10A.
I imagine it's a pita to find the raw plugs that fit a particular power supply model though.
According to this, 18ga wire is only .823 mm^2, but friedcat's user guide says to use min 1.5mm^2, which would be 15ga wire. I would really like to see pics and specs of people's setups. Can we start a erupter porn thread people? http://en.m.wikipedia.org/wiki/American_wire_gaugeCan't see where he says that, but that's why I use 2 or 4 cables for each purpose. |

All the corsair PSUs have 18ga 9A rated wiring. I've tested putting 23A through one and it gets warm. Not hot, like 35C. Putting 10A through a single molex isnt a big deal, especially if using a splitter. |

How can it be that a 4 pin molex can provide around 120 watt?
In a other thread they wrote that we should put the negativ vable in one hole
Or it would overheat. A youtube video shows as example
A melt cable.
Please help me understand ^^
ps: is it possible to change the mhz manually?
It is my belief that this is the best config. This wiring has been running for over a week now, no temp problems what so ever. By using a molex splitter you're doubling up the local cabling, so a 4 pin molex can provide ~120W.
this setup needs to be done for 1 blade ?
Yes, on each blade your cables should look like this. |

Uhm, these fans can get quite noisy. I don't think I want to run a cable from where I will put them and my router, so I will have to buy a wifi bridge, small ethernet hub and a bunch of Cat5 cables. It's going to be always xmas in my room That's why I've recommended a fan controller. I have 2 (soon to be 4) blades no more than a metre above my bed and the passive wind noise from outside is louder than the fans - yet the heatsinks remain cool to the touch. |
