According to UPS my 4 miners should be here Tuesday!!!!
Happy for you. I am still waiting for my repair items  Didnt take 3 weeks for a significant amount of miners to break down lol What happened ? broken hashing-boards ? Not until now. And i pray that they don't fault. They have thousands of HW errors already while other got 30 lol But most of the control boards were broken. And bitmain being bitmain, they are letting me wait and its a pain in the ass troubleshooting and solving the problems. Have been dealing with them for almost 2 weeks now and im still waiting for replacements. I admit shipping times and customs play a role too Where are you located? If in US, Bitmainrepair might be easier. Bitmain also has a repair location in the US now for the warranty repairs. See their official repair guide at bitmain.com for more. |

Well if it for sure is non-condensating, then there is no problem with corrosion or anything and you can forgot my warning.
It's hard to say when I haven't visited this place but it's better give a warning to give a little shake to think about things.

$2500 min order 100 pcs wtf
I could probably get a group buy together ...but with no reply from emails from them ..my view is they don't give a F*ck and after that price rise of LTC .they may have just decided to keep them in house or sell to data halls in China always iffy when folk don't reply to common questions AT ALL just saying they may be sold out or something..deafening silence brad edit: and before people ask me to join their group buy...unless they reply to me...I'm not really gonna trust a group buy from a newbie account ...not a slam...but silence on possible 100 unit order means to me..they may already be out...so I need a reply just to show they give a damn (end of rant) That is a really pessimistic thing to say. As far as I'm aware of things, BW is receiving hundreds of e-mails after this review here at Bitcointalk was done AND multiple news sources had news about it after the review. Give them some slack. You got to think yourself in their position. |

Bitmain writes that the warranty is void if the machine was used in a "humid environment"
Does anyone know what exactly they mean by that ? I would like to run it in a basement with around 60% humidity atm.
I expect it to decrease as the heat increases.
These little hw-errors which are seen in the interface are normal if they are not very high, is that right ?
That is too much humidity and you are breaking the nominal values that are allowed for Antminer, so you might not get it fixed with warranty repair if something goes wrong and they notice damage because of the humidity. Specs https://enforum.bitmain.com/bbs/topics/4081 |

There is no universal and ready answer that somebody could give you. You must do your own research and then make your decision. Period.

They do fix the BTC ratio when you make the order for real. It's not a realtime Bitstamp price, but much better still. I know because they did it when I ordered one A5 preorder after a long thought. Let's see how that turns out.  Delivery in November. so how many did you order and what was the BTC price you have a recipt ? I ordered one unit and the btc price was valued approx. 4200 USD . |

Of course you use the thermal paste.
This is a stupid question and a stupid thread.
Sorry.

It's just another bullshit scam.
Guys, please don't waste your money and/or time on this..

i can't get the differences between those two.
one them is 5 pairs pci-e other 9 pairs
all numbers are same max output etc
5 pairs one is for s9 l3 and d3
9 pairs one is for l3 only ??
any idea prices are $105 $115
More cables, more price. They are both the same power supply. But you must understand that the one with 5 pairs cables (10x cables) is good to power ONE S9 or L3+ or D3. The one with 9 pairs cables (18x cables) is good to power TWO L3+ or ONE S9 or ONE D3. Thanks HagsFIN unfortunately i have 5 pair cables batch 20 pcs any way to convert 9 pairs pci-e ? any one know this ? You would have to re-do the cables but especially if you don't have a clue what you are doing, I do not recommend it. Use it for a one miner and buy another psu for the second miner. That is a good option too. |

So if for the A4 the price per unit is 1050 USD for 280 Mh/s, it means that the price per megahash is 3.75 USD.
The price for the A4+ would then equal 520 * 3.75 USD = 1950 USD
Actually I think the $1050 is the 70% down amount with 30% still due when ready to ship. So I think the price for the A4 is around $1365ish a unit in USD + shipping. So that is closer to 5.05 per MH in USD I think if my math is right. They have stated in the email that they think the MHS could be as much as 20% higher than the lab machine which already performs at 520mhs, but they don't know for sure yet what the final figure will be as the hardware is still being tweaked. So at that price you would be looking at around $2626 per unit at the 520mhs rate... These are all rough numbers of course and will change with the final unit hash rate. Well that would be a complicated way to present the total price per unit |

Yeah, why are graphics card miners so blind?  No offence, but this is just far too common thing. |

Yes, but your mains voltage must be at least 208 VAC and you must have A DEDICATED CIRCUIT for it, with nothing else equipment. With 16x 6-pin PCI-E cables that come with this power supply you are good to go powering both the A741 and the L3+. Should be no problem, but dedicated circuit not necessary depending on your amps. If you are running a 30-50A @ 220V circuit (pretty typical for most datacenters) then you could power up to 6KW on a 30A or 11KW on a 50A circuit. The racks I use all have 30A dual-redundant supplies, so 60A per rack. That allows me to run up to 12KW per rack. Pretty hot though, so cooling is imporant, make sure to block-off any unused rack space to keep the cool air in the front pushing through the rigs rather than around the rigs. True. I said dedicated circuit as here in Finland and other EU area 10A (1.5mm2 wire) or 16A (2.5mm2 wire) circuit for regular electrical sockets are common (type F socket in Finland). So it is just how my brain has used to be think this through. |

I have the same problem with only 3 of the 4 boards working properly... Is this something fixable or must it be sent back to Bitmain? Just obviously concerned about the cost to send the miner back, the loss in earnings as well as probably having to re-pay customs to get it back!
Any help appreciated. Pic attached on Twitter (tried to reach out to Bitmain) - https://twitter.com/daveharwood4/status/903229426019786752 It is time to send the hash board connected to the connector (Chain 3) to the warranty repair for Bitmain. I have my L3+ running with three hash boards, because I also have one hash board already sent for the warranty repair. It performs just ok with only three boards, no problem with temperatures or anything. You need to follow this repair guide carefully for the warranty repair https://shop.bitmain.com/workOrderGuide.htmAnd ask Bitmain the permission to open the miner and remove faulty hashboard before doing anything. |
