The timing of that monstrosity is awful, it is as useful as tits on a boar  Wink - unless it has some newer chips than the 1385

I think that this purchase would be a disaster.

This is S9 design with older S7 chip.

The same disaster, as S5+  before S7.
..................................................
Now you have to know the S9 parameters

5.Dimension:306mm(L)*150mm(W)*275mm(H)
6.Cooling:2×12038 Fan





https://www.bitmaintech.com/productDetail.htm?pid=00020160421034108161se80ckq8069F

I dont know why they didnt just come up with a 3-board design using undervolted chips for less heat and better efficiency. I bet a 135-chip design could manage 4.2TH/1kW, which would be pretty compelling.

Including the PSU seems silly in most places where PSUs are readily available in stores. Unless its <$80 for that PSU it not really worth the hassle and shipping costs compared to the local NCIX/tigerdirect.

but i love the top bracket. Id buy just that for my S7 as it looks like a great way to minimize cord clutter from the PSU

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

I have no idea what will sell in China.  But it's the price that baffles me.  It's like they are sticking it to their own countryman.

Do not forget. This price is with the Chinese sales tax. ( 17% ? )

Wow, even speculating the frequency. I have a feeling that this will be the closest to the S9.

... and then the chinese people call it S11 and your speculation is over Cheesy

Anyways. I hope after claiming the first position they will stop a bit - even if they have a new chip.
They shall use it for own farm and dont sell it.
This would be a good long time invest for all who already have an Antminer or who want to buy a new S7 right now.
If S9, S11 or whatever is on the market the ROI for old mining hardware will be in danger (like it is and was always).
Every time the difficulty gets a bit higher the earnings will be harder --- and everytime the hashrate increases --- the difficulty will increase faster, because of passing more blocks is faster, too.

For me the winner is fix. They should be ready with a new asic out of the box for the day a competitor is announcing a new asic, but for now --- slower is nicer Wink

Just compare in here: http://bitcoin.sipa.be/
or somehwere @blockchain.info  Roll Eyes Tongue

We dont need exploding hashpower -- we had enough the last month  Shocked Cool

I wouldn't buy that, I'll buy a new process, fed up of the 28nm which right now, it is having a longer life than 56nm...
Bitmain is hellbent on diluting the entire mining market at all costs, so I'm not going to help them any further.
They counter difficulty increases with putting in more hardware on the market, so there is no new-diff-settle time; which is anti-Bitcoin... it's a market takeover.
Like it or not, Chinese pools amount for over 75% of the pooled hashrate.
Who profits from this the most?  You guessed it.  Buttmain.

This is just a pilfer miner, like the S5 was... just meant to take your previous miner's good coin yields to pay for the cheap-ass hardware.
Nah, I'll keep my coin this time and wait for the next generation miner, and potentially, next non-dick manufacturer... but they all are.
I bitch at Bitmain but KnC & BitFury are 1,000 times worst and will be until there is serious competition.
Until then, enjoy Bitmain's monarchy, BitFuty's lies and KnC's selfishness.

+1 for the bracket, would do anything to be able to tidy up the mess of cables and PSU's currently plaguing my s7's

zip ties and more zip ties will clean it up!

Stop buying industrial miners, running them at home, and then complaining about the noise.

After running the calculations am I correct that holding all things constant (same elec. rate, shipping from Bitmain, difficulty,) the ROI seems to be about the same this S7-LN vs. S7  (within about 10 days or so form the calculator).  I am not even questioning if ROI is even achievable with everything else going on.. halving..next gen equipment etc. Just doing a direct a comparison between these two models.

my calculation allotted for buying a S7 PSU for about $150, and being able to use a $100 coupon on the newest Batch s7 (which I assume cant be used for the S7-LN?).

This would make total shipped cost of Each:

  • S7-LN = $276
  • S7 Batch 17 + PSU = $550

My point is, unless you just need a smaller / quieter machine... ROI wise & comparison wise the S7-LN does not seem drastically different that the S7.  Does this seem correct?

I believe they are aiming this miner at people like me.  Who want to mine but I don't want to be running an operation.. Just something that uses a bit of power but is still actually adding some calcs to the network.  The idea my CPU at 500 hashes is adding to the network is just BS.

I am highly considering one, still a little more power than I would like to use BUT it is in the range it won't overload a circuit and I can have a few more things on the circuit.

I think this is them just clearing out old stock that would otherwise just sit there losing money for them. People wanted a lower power miner and dont care about ROI, so here it is!

As i know all coupons are expired. is this correct?

If not, can somebody check if it is usable for this miner?
