Guess nobody has any.. I really would like to purchase some. Also, anybody know of the specs? since the company went out & the website with them, I can't find anything. Not even a cache copy of their website to find specs of the card.
@dogie, there's already plenty of guides for it :p leave some of the guides to the rookies out there you've got enough hahaha
its just a hashfast EVO repackaged IIRC - layout, setup, and instructions should be the exact same |

Update
Q1. AMHash1 price is so competitive, why still sold slowly?
A1: Distrust, some people don't believe cloud ming when they hurt by someone, the other people just suspect cost control of AMHASH.We are company established for long term , people know who we are and where we live; AM found some partners who hold very vey low electricity power factories.
Q2. When will the contract start?
A2:Contract will start on 31st Oct, investors will get payment from that day.
Q3.How can AMHash and HAVELOCK supply more trust, how can u let people trust no gather capital and run away?
A3: AMHash will leave bitcoins on platform for dividends, and HAVELOCK will be the third party to monitor and operate the dividends.
Q1: the power rates look to be around $0.09/kwh - thats a decent price, but i bet the actual costs are lower. part of the fees is maintenance. Q1.1: The problem is that asicminer shares have not paid dividends for months, and constantly slipping in value. Apparently they sold/are selling 5PH and still no dividends. It would be nice to see the IPO price reduced slightly, because its clearly not selling out very fast |

bump to the top - plenty of cables in stock, and the splitters work great for antminers

hi,and do you have any circuit scheme picture for hassing pcb board for S3 + for better checking and fixing error with some resistor or capacitor?
Mirek
Dogie might. Pretty easy though, the inductor has big pads. If each inductor has a 0.75v measured across it then it rules out any regulator issue. The next step would be to closely examine the chips to see if there's any obvious reason why it may not get comes or power. Likely it will be within the first cluster of chips on the leftmost side of the pcb, as an issue with these chips will prevent the chips to the right of them of working correctly |

Back in batch 2 of the s1 units I had a defunct board with the fault appearing to be the dc regulator. They organised an RMA for me without much issue.
Does the second board just not show up? Open up the case and check for any issues before going for an RMA. A loose cable could be the cause, or a broken capacitor/resistor could be easy to fix at a local shop same-day.
If you have a voltmeter, look for 0.75v across the inductors (grey cube like objects)

Look at my signature.i sell 24" 16awg pcie cables. The ends are stripped, so it's easy to either solder them to the server PSU, or buy the correct size of pins at a hardware store and crimp them to the wires.
And way cheaper than most other sellers ($1.40-$2 each in the quantity you want, as opposed to $4-6 elsewhere, often with only 18awg)
What is your shipping cost to the UK for 10? Prohibitively expensive as if ships from Canada. Probably close to $20 using the cheapest surface option, and closer to $30 for tracking. Shipping to the EU only starts to make sense at >40 units |

The point and what you said are valid, i've seen too many power supplies come from China which can only be called an electrical death trap and/or an EMC compliance nightmare.
Seriously, anyone can get power supplies that can kick out 6A, we don't need power supplies that will either throw out too much RFI or burn someones house to the ground, after all, anyone reselling these in Europe (and I assume other countries, but I wouldn't know) will be liable for it.
These are the same PSUs you buy in the US and EU from Amazon - it all comes from China. We looked at making a no PSU SKU and the price wouldn't make a lot of sense so everyone would buy the with PSU SKU. 1. Pieh0 is right, there is a big internal difference between a well designed quality psu and a cheap firestarter... You are welcome to post a full CE check report and PICs from the internal design 2. It make no sense to pay high air freight cost for a PSU So please offer them without PSU and let customer decide (if anybody want to buy them ;-)) We're talking about AC/DC PSUs, not ATX PSUs. The non AC/DC package fundamentally didn't make any sense. 1) The U3 packaging includes the PSU internally and so its not as simple as not including the PSU in the first place. The PSUs would have to be actively removed. 2) The PSU's weight isn't significant at all compared to the miner. 3) The price difference was too small to make it worth creating another SKU. 1) no its not, it's an external brick like the BFL jalapeño had. 2) it probably is. Likely about 15% the weight of the final package |

You can use only 1 pcie slot per board with no issue. I've run overclocked s3/s3+ units this way with EVGA 1300, enermax 1050, ultra 800, and an eternal 1350.
All do it without a problem. When possible I double up, but it's not really necessary. The cables can handle the load without issue on a quality psu. If not, the cable will be noticeably warm in under 10 min. Easy to test.
I sell good quality pcie splitters in my signature link if you really want to use splitters, but it's not required in my experience for the s3

Yeah I've been looking at the Server PSU's and there dirt cheap, only problem is I cant find any breakout boards in the UK.
Breakout boards are over-rated! What PSU have you looked at? You can rig-up your very own contraption .... remember, bitcoin mining is about ROI and the less you spend on the PSU the better / faster to ROI. If you are not afraid of the solder iron, you can drastically reduce the cost of a PSU (both in terms of outlay and reliability) by over 90% if not more by going the server PSU way .... your choice! I use Dell server PSU's and did not need breakout boards for them, simply soldered the wires. Was looking at this one to power all four. img<<>>img That will definitely power all four. All you need is solder a few wires, then connect those wires to an inline cable connector, and then have your PCI-e sockets off the inlines. Ok I know what to do now... Now where do I find a ''how to make VGA PCI-e cable with out blowing your self up'' thread Look at my signature.i sell 24" 16awg pcie cables. The ends are stripped, so it's easy to either solder them to the server PSU, or buy the correct size of pins at a hardware store and crimp them to the wires. And way cheaper than most other sellers ($1.40-$2 each in the quantity you want, as opposed to $4-6 elsewhere, often with only 18awg) |

Anyone know how many watts the cooling system uses? I'm guessing around 30watts. Wondering if it would be possible to run 2 C1's (840w) on 1 1600watt EVGA power supply with 2 water cooling kits even though it's a little over specs, anyone already try this? (70A each C1 plus water cooking kit x2 is more than the 133.3A 12v rating for the 1600w).
Probably more like 50w to run the fans and pump. Even if the psu doesn't constantly trip on overcurrent protection, your ac/dc efficiency will suck if the psu is pushed past 105% rating. If it's 92% efficiency at 80% load it may only be 85% efficiency at the load you want to put on it. |

any way to undervolt the RK-box for better power efficiency? I would prefer to be around 1w/GH even if i lose 10% hashrate

I know they can run on 2, I’m wondering if I could connect three to each miner or will it only work in arrangements of 2 or 4?
You could run on 3, but the load won't balanced across the 2 cards - one card will only have 1 cable powering it and that cable will have the highest risk of melting. You could buy PCI-e splitters and run 3x PCI-e cables (2 + 1-into-2) per S3 miner. That way you can balance out the odd cable across the 2 cards. just throwing this in: I sell spliters perfect for this (see link in my signature) Its a 1->2 Y-shaped PCIe cable made with quality 18awg, 6" per arm (12" total length when spread). Can easily handle 140W/arm, more than enough for the S3+ |

Hello So I have 4 x S3 miners coming next week and I’m just about to buy the power supplies. I was thinking two Corsair HX850 (850Watts), only snag is they have 6xPCI-E 6 connecters and the miners take four each. Would like to over clock them abit and concerned the wire will heat up to much. http://www.corsair.com/en-gb/psus/hx-series I know they can run on 2, I’m wondering if I could connect three to each miner or will it only work in arrangements of 2 or 4? Looked at this guide which is great but isnt that detailed. https://bitcointalk.org/index.php?topic=702653.0Cheers  Its better to buy an server PSU wich is more efficient more reliable and much easier to exchange when the break down. All you need is a server PSU + a breakout board. I have got an IBM DSP2000 PSU wich can go to 2500W or 200A on the 12V rail.. no PC-PSU can beat that (bought it for $ 45) Interesting, are the server PSU's even better than the 80 Gold Rated ATX PSU's. I have seen on youtube some guy tested a crappy PSU against a Corsair and the difference in power usage at the wall was 120watts! The crappy one was pulling 470watts and the Corsair was pulling 350watts thats alot if your farming. Do you have any brands of server PSU and breaker boards...im in the UK. god no. ATX Gold is way better than a lot of server PSUs, particularly the Corsair series. I own an HX850 in my GPU rig and it holds its own. Quiet and power efficient. I have no concerns about it being 90%+. Most server supplies ive seen though are extremely loud, the custom cabling can be an issue to solder or source parts, and often the best deals are on used/refurb units that may not stand up to standards after the original usage. That said, server supplies are good if you want to save some money (which IMO quality PSUs have resale value and work better/longer than server gear) or where PSU space is an issue and high-density gear is an issue. But for the home miner with a pair of S3+ miners, the HX850 with 6 cords spread between the 8 slots (4 would do, but why not all 6  ) is sufficient for stock speeds, but you wont be able to overclock, as anything over 390W/miner (about 480GH/each) will start pushing the PSU near limits and lose 2-3% efficiency. To overclock you should use an HX1050 or better |

what do the silver/gold 2013 coins go for these days? I was selling at 2.3BTC each a while back but I feel like the value must be creeping up towards 3BTC by now

I'd love to see whatever they're coming out with be a direct drop in / swap for the current systems. As in unscrew the old boards, swap the heatsinks to the new boards, and screw in the new ones.
would be nice, though i expect the housing doesnt cost much to produce, maybe just some shipping expense. anyway to get a better power consumption from these? 1.2w/GH is becoming too much power usage for where i live, and I'd be happy to lose 25% of my hashrate in exchange for <1w/gh |

Got my 2nd batch 2 S4 yesterday, plugged it in and it is hashing away after opening and checking power supply. But when I did a status check of my first
batch 2 S4 I saw that I have 4 asic chips showing x's... 0 on 1st, 1 on 2nd, 1 on 3rd, and 2 on 4th.
How many chips need to be not working before doing a return?
more than that. 4 non-working chips is like a 3% deficiency, isnt it? try a reboot, both through the software, then at the wall - usually that fixes these issues |

At the end of the day Bitmain is a company like any other they will aim to always operate in a profit situation. Meaning if it isn't profitable for them to sell miners to end consumers they will just mine with the units themselves. Your example of them asking $150 to ship a miner that costs $198 is not fair on bitmain. Do you think that they are able to produce the unit in the remaining $48 that they would have after paying the shipping? From experience in manufacturing miners i can tell you that they wouldn't. Bitmain are one of the best miner sellers currently operating i think they have exceptional devices and exceptional customer service. Taxes are up to you as they are with all miner companies.
Bitmain are one of the only miner manufacturing companies i would trust with my btc.
THIS. when BTC was $600, and an S3 cost $150 to build and $100 to ship, 0.7BTC was a fair price to charge because the miner could produce a positive ROI and so could bitmain. At $350/BTC it doesnt work that way, as the 0.5BTC sticker price means that including shipping would cause a loss to bitmain. the alternative? manufacture your own hardware. If that doesnt work then you are SOL - this is a fairly competitive market and I can guarentee you that Bitmain is trying to sell units at a reasonable price. |

Are these aluminum or copper wire?
aluminum wire. the 16awg can handle over 280W easily (I beleive someone said they loaded over 350W without issue - i havent tested that far) |

ps: im looking at the possbility of 36" cables or other esigns in the future - any requests or thoughts? (ps: i cant strand two connectors on a single 16awg lead - the cable is too thick - hence the splitter)
What are you trying to accomplish here? I may be able to work something out for you. Was looking to make 2-headed cables similar to what many psus ship with, but using quality 16awg wires. I was informed that the molex pcie crimp pins do not fit two 16awg wires, 2x18awg is the max Ah, I see. But why would you want to increase the load so much on the 16awg lead by adding another terminal end? I would think separate leads would be cooler and safer. Is it a space saving issue? Anyway, just between you and me and the wall I can do double 16awg wire crimps even using the wire you sell. It takes a bit of finesse and patience (and a couple of tricks) but it can be done correctly. It is the method I use for making my 2:1 reverse adapters for Neptune/Titans.  mostly for people who like filling all the connections on stuff like the S3, or multiple lower power devices. Would also mean 6" of wire for the second connector as opposed to 24", saving some cost and shipping. Mostly just interested in what sort of wires people are interested in, as the majority of interest is the leads, but I also go through the 18awg splitters pretty quick. ANYways: I now have >500 leads and 100 splitters in hand today |
