Nice, i hope to get one soon
@Bitmain: Will you offer this one at DHGATE.com also? Does it run on WIFI?

wow this seems very powerful and also most power efficient miner in the market ...
but i dont think the price is acceptable though.
but i dont think the price is acceptable though.
I have to agree. Unfortunetly the size and price of it is bigger than I expected. I was expecting a 2.5 ths unit with around 3-3.5 btc price. Seems like I'll have to wait and save some more coins.
And it does look loud. Those fans look like S5 fans and I can't imagine 2 of them in a house.
Yes. It could be very loud.
I don't really find anything definite for "12038 Fans"... What's the specs? Thanks.

Guys, can you use two 750W PSU to power this miner ?
maybe if they are identical, maybe but is too risky.
the point is that you will have to power 1 board from both psu's and that is not recommended!
u can use 3 of 500w
u need single rail psu with at least 35A on 12v . the one psu that is powering also the controller and the fans i'd say at least 38A!

not at all
You need 410w at the wall for each hashboard, from ONLY one PSU...
Well you could use different PSU's for different hashing boards. I would prefer one though.
Biggest thing is not to mix psu's on hashing board. IE one hashing board and two PSU's going to it.

I'll wait for lower prices, for me it is too high, 
August 30, 2015, 02:52:57 AM
I like this miner, but the price seems to be too much, I thought at least 1200 dollars,
Agree the price is too steep as others have said. The issue though, as others have also said, is I think they already have the S7+ made and in their own home farms. The design looks too easy to replicate based on the S5+. Which means they are now trying to sneak a poke at early buyers with the high price, before either the market collapses or the difficulty pops due to the increased Hasing power of the network.

Very, very, very high price. Game over for home mining I guess.
+1
I think the price is too high but efficiency of the miner is good.
maybe 5 more years and no more home miners, only big commercial miners.
In 5 years will there be any more bitcoins to mine at the rate of technological advancement?
I think there will be, there's no other way but to go up.
It's just maybe the future of mining is not for home, ordinary people like us would use it as a commodity then mining or process of transaction will be all commercialize. (just my opinion, I maybe wrong)
But that defeats the original purpose of bitcoin. It was the centralized production and control of transactions that makes a fiat money supply an issue in the first place. The control of supply is only one side of the coin. Centralization leads to governments being able to dictate to those entities how the market is going to work. That's the problem with fiat money and Central Banks. Decentralization of the network is the only thing that keeps its integrity in check. Once it is centralized it is controlled by wherever that centralization is occurring. And you can damn sure bet where money and assets or human endeavors are involved, the people with guns (IE Government) are going to be right there with one at someone's head. This may be an issue for the 'market' to solve. And by solve I mean it simply de-capitalizes because it no longer trusts the network. Then when the mega entities are gone, the process starts over. Don't give a crap how 'efficient' this miner is, it won't live at $20 per bitcoin.

Only way to 'not' be game over is if the network figures out someway to start punishing certain entities and singling them out to intentionally reduce their ROI and make them decentralize. Namely by crippling them through increased difficulty intentionally. Almost like breaking up monopolies or mega corporations.
Once manufacturers started large scale farming operations the writing started to get put on the wall. And hence the increased focus on efficiency. because if the market takes a tumble they can still keep their operational costs in check with ever increasingly efficient miners. While the material cost of the miner has long since been paid off, hashnest selling mined coin etc. It allows them to ride out the lows a lot easier then say someone with a S5 who is at half the efficiency level. Never mind hashing power increase.
PS: This is also starting to make me think a Proof of Share model vs Proof of Work model is going to be more important as time goes on.

How loud are they ? I doubt they are silent like the S3 but more like an S5.
They got probably the same 70 dB fans on them the S5 does. Front and back. So expect two jet engines.
Sucks, won't be able to run those at home ... never
It's too bad - this chip could be used to make a great home miner. A 60 chip design like the S5 with the improvements they've made in cooling could probably run at about 1600-1700 gh/s somewhere between 0.6v and 0.66v and probably pull less than 400 watts from the wall. Cooling a miner like that would not be loud at all with good fans. That's not too far away from the S3 in terms of heat generated. And they'd probably sell easily for around BTC3.
My thing is I think Bitmain is joining the big boys and then intend to look toward crushing the home industry. It's going to be farm after farm after farm, with the only way a little person really making an ROI is if they go with the cloud mining which Is where they dictate the pennies they give you for up front capital. And your return will probably depreciate faster than a normal investment vehicle. One thing I give scrypt miners credit for. Those guys are fighting back intentionally screwing with stuff to make ASIC hard to bring into their market space and make a decent product. Or a product that could be screwed with and turned into a paperweight with a slight changing of the scrypt. Even Bitmain had to kill their Scrypt miner project. I have no doubt they will try again, but I also have no doubt the scrypt people will fight back again.

- Operating Temperature: 0 °C to 40 °C
Operating Temp is really low 40C? Other miners as well as bitmain units operated up to 60C.
That is only 104F or so. Hope you got air conditioning or live in a northern region.
The S5 has a limit of 35C. These are ambient temps, but I can see a data center getting higher than 40C and certainly higher than 35C without AC.
I'm sure there's many S5's that have been running at ambient temps above 35C in the past couple months. Any performance issues?
August 29, 2015, 11:52:21 PM
I wonder how much this will over clock to?
We don't know where voltage is set ... but the spec sheet lists 32.5 gh/s per chip at 0.66v. If that's where they're set, with 162 chips that comes to 5.265 th/s. This is pure speculation but that would seem like a logical limit for overclocking. But I don't fully understand (if I do at all) the differing effects that voltage and clock rate have on hashrate... hopefully someone that does can let us know if this is a reasonable assumption.
