'The right to privacy matters'
Bitmain as much as I like your lovely surprise announcements about your product availability it would really help me to plan ahead to prepare/purchase the necessary BTC for your upcoming Batch 3 S2.

Since you are supposed to start shipping S2 batch 2 in less than 48 hours could you please tell us when you will be opening S2 batch 3 sales and price?

Thank you

you will want to be ready by the 10th. or 11th and have at least 3k in btc.

 although a second source has told me have 3.5k usd in btc.

So you  need 7.5-8.5 coins ready by the 11th.  

 Please  remember you could get 7 s-1s  for that price  includes psu's wires and a gigabyte/cat5/6  switch

4xS2 Units arrived today.

Two of the four boxes very worse for wear. One box was wet across the end as if it had been sitting in water.

Each machine had a few boards out of the rails. One had it's internal network cable unplugged. Another one had the screen unplugged. One power supply had been badly installed and two of the screws had stripped. the PSU wis sitting at a bit of an angle.

Only received rack mounts for 3 of them.

Reseated all the cards and they all ran fine. No sign of any water getting through the bubblewrap.

One board out of all 40 is showing a zero temp reading but is hashing away regardless.

Unexpected Bonus: They came with Australian plugs!



hash rates please and watt use please.  4th at 4000 watts? I realize you need a k watt meter and may not have one. but at least hash rates  .

 Thought about the S2 but running 6 S1 for a month got to be better than twiddling your thumbs waiting you S2 to arrive
S1 got me almost 4 BTC ($2,000+)
Waiting for S2 0 BTC ($0)

Add the above into you calculations!

AntMiner S2 1TH/s Miner (1w/GH/s) Batch 2
Price:      3599 USD ( 8.065 BTC )

AntMiner S1  180GH/s
AntMiner S1 - 0.893BTC

1000/180=  5.56
AntMiner S2 = 6 AntMiner S1
8.065 BTC > 6 x 0.893BTC

8.065 BTC >  5.36 BTC

so buy AntMiner S2 or 6 AntMiner S1 ?
will be ROI if buy AntMiner S2 or 6 AntMiner S1?

Power is a factor here. 6 S1s will use more power, and generate more heat, than 1 S1 will.  If heat and power isn't a factor in your equation, then the S1s make more sense.

All of our ants @ 393mhz get 200GH/s, and pull 410W at the wall with an 80 Plus Gold 750W Rosewill PSU, which is right at 90% efficient at. That means our Ants are pulling 370W from the PSU, and this includes removing the blue/white wires from the fans so they're running at 100%.

If your 2 ants are pulling 900W, you need a better (more efficient) PSU.

I't was a pretty inexpensive PSU (under $80, possibly under $70) so it may not be the most efficient, good brand but I don't remember at the moment and it's not much of a concern to me right now, I am paying less than 6c per kilowatt of wind energy--it's unlikely I would have gotten ROI on a more efficient power supply and with wind energy--no real reason to feel bad about using a little more. Smiley

Either way, it's still necessary to account for both the power supply and the additional energy usage (depending on rate, of course) of the 6 S1's over 1 S2.  I'm not suggesting it wouldn't be worth it--but you can't base it off the math that was provided.  Also, who knows what the S1s and S2s will be priced at when they bring them back, it's kind of a waste of time and energy to even try to made a decision now without that information. 

I definitely plan on playing with frequencies a little more to see if I can get better hashing than with them set to 400Mhz, whenever I have a chance. 

I cannot open https://www.bitmaintech.com/ nor could I ten hours ago.

It was working for me earlier and it's working now.  Also--THEY HAVE S1's IN STOCK!!!!!!!

Glow Stick Dance!

Also, I have 2 words for any serious ASIC miner, that worries about temp and noise:

IMMERSION COOLING
Anything else, is insanity.
10-30% of mining energy costs are wasted on crappy cooling methods.
Throw away the box and get a tank and a bunch of mineral oil.
PC Overclockers and datacenter CIOs have been doing this for years.

It isn't worth the time and added expense for .075 BTC per day that an S2 will generate.

You also forgot to factor in 3000w worth of PSU, or something close to that if you intend on over clocking.  My two S1's are pulling in over 900w combined.
Just to reiterate: the S1 does not come with a power supply, the S2 does. You need to add the cost of PSUs for your 6x S1s. Also the price of BTC at the time the S2 was on sale, as someone else has mentioned.

It doesn't really make sense to talk about the price of S2 at the moment since they are not for sale (yet). When batch 3 is opened I imagine they will be cheaper than batch 1 or 2.

Bitmain,

  Would it be possible to buy S2's without the psu installed and a little cheaper?

+1 bitmain, definitely should offer this.

I have a 1000 watt seasonic plat 2 s-1s clocked to 400 mhz giving me 406 gh.

 I use 805 watts and I have no issues with this psu.  it is the best for 2 s-1s overclocked.

'The right to privacy matters'
so fast questions.

 who has one mining at btcguild ?

who has one getting 1th ?

 who has one at 950 watts or less?


So far from what I read I am not that impressed.  

 Seems to me a 2x s-1 under clocked to 300 gh pulling 300 watts

 would have been:

 A easier to make
 B cheaper to ship  
 C  fit in a much smaller case

 Frankly I think they fucked up.

They will need a 1200 watt psu or sell it with out one .



  Here is a prediction buying these psu's at amazon  will allow for one to be marked up to 400 from 290.

http://www.amazon.com/gp/product/B00JG5LSN8/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1   this psu is basically the same as a corsair ax1200i .

 after reading the thread  i ordered one of these .  I already see these marked way the fuck up


I would really like to know how you get a S1 to 150GH using only 150 Watt!!

There is a thread with a lot of info on how to undervolt and underclock an s-1.  Right now diff and power do not call for the mod.


https://bitcointalksearch.org/topic/guide-undervolt-antminer-s1-119wgh-at-the-wall-526060

  this thread describes a how to  that achieved  140gh and 160 watts.

   Now since bitmain built the s-1 and the s-2 and used the same chips  they should be able to improve on the mod above.
I have 7 s-1's  when diff gets to 26000 mill at my power price of 16 cents a kwatt and if btc is 450 usd they will be break even.  So i will attempt this mod.   if my 7 machines drop to 980 gh and drop to  1120 watts they would still earn money at 16 cents a kwatt and 450 btc.   until diff pushes 38000 mill

Its worth noting that whent he S2 Batch 2 first went on sale, BTC was significantly higher (I think it was only ~6.2BTC when i ordered). Makes the price comparison more reasonable.

Also, it seems like the S2 can achieve 1.15TH/1.25kW without much more than an extra PSU wattage. If so, you now have the same hashrate as 6xS1, but for about 1.1kW less power consumption

If your 2 ants are pulling 900W, that means your PSU is only 82% efficient. You get a better (more efficient) PSU, and your power use drops down to 820W.

Seriously, what were these bozos thinking by puting a sub-1000w PSU for a 1000+w application?

For anything in the 1000w mark, look no further than these 3:
