ANTMINER S2 Discussion and Support Thread

[goggles1200]

On the bitmain site, the price is fixed to 3899$ and then the reflected BTC price to side. I wonder what the production costs were...

[klondike_bar]

I have  3 high quality 1000 watt psu running 6 s-1's .  my need for the psu is 0

So an good enermax cost 150 usd shipping is 20 usd.

 Sell me a 1th unit without the psu.

reduce the price to 5.6btc maybe 5.5btc

Sorry, where can you buy a 1000W Gold Enermax for $150?

 you are correct i can't find one lower then 200.
but with 3 of these what do I need it for.  

plain and simple dumb move to force that psu on us.  we purchased  lots of antminers from them and now  they want to stick us with  psu's many of us don't need.

and I want the new gear but I feel that the psu is a problem for me.

I have no qualms with a PSU being included so long as it does not mess with customs, and the price is still reasonable. If they are able to buy a few 100 PSUs for $100 each (compared to $200-270 in North America) and the savings of that outweigh the added weight, I say go for it. It will save me lurking around in all the local tech stores trying ot find deals that dont involve an MIR or $20 for online shipping

Disappointing. That's going to make ROI calculations much more complicated.

[CroverNo]

It's so much cheaper to buy the S2 in $ rather than BTC I save about £400 aha!

Customs fee will be a bitch to EU/UK and with PSU customs will bloody freak!

Bitmain can you please create an option to ship without PSU so I can overclock this bad boy to 2 + Th/S

and to pay $3899 for 2Th/s this I can live for

Not many people will know the full power/ what it can really make at overclock.

Hopefully Bitmain will release these details but tbh 600+ Chips per customer is a lot.... Bitmain must have loads of these introduction to use that many.


If you asking me best using less chips with 28nm design... but oh well I will see what Bitmain says

Do you honestly think you can overclock it 2TH, that a 100% increase.

[Biffa]

They had a good system. Charging Btc lowering the price to reflect market value, selling only from stock etc.. This is a disappointment really cost wise and configure wise. Just IMHO of course. But it will still sell

Bitmaintech was, until now, a very good company that truly was supporting BTC.

Now Bitmaintech shows less trust in BTC because the company is changing prices of its miners with decrease or increase of BTC value.

[Skaterdiejosh]

Over clock at 1.5 Th/s should be able to do that ?? Damn tax return check better hurry up lol.. Thinking easy 2000watts at over clock ?? You would need to add another 1200 watt power supply ..

[SVK]

Now I'm really torn between Gridseed and Bitmain
At this price I'm really unsure.

BTC difficulty is sky high and will go higher.
Do you all think that for small miners it's time to move to SCRYPT ?

Im personally going to get of the s1's, maybe replace it with a s2, buy another s2, and then buy either the hex 6 fury USB sticks, (15 gh/s per) or get some usb stick scrypt asic miners from either zeusminer.com or fibonacci.io ALso, whats your definition of "small time" ?

[dropt]

Not to beat a dead horse or be confrontational, but what is so revolutionary about the S2 technology wise?  The enermax powersupplies?  The ugly silver case?  Please point out where they're pushing the edge.  The Lightning, Dragon, JT, etc are in the same space (1TH/s), are pricey at over $4k-5k each, but at least they're using 28nm A1s(stolen or not).

I'm just trying to see to value proposition with regards to the (same old)tech they're using.

There is nothing "revolutionary".  I'm not sure why there should be the condition that something be revolutionary to warrant the manufacture and sale of a different model than the S1.  They've made the unit wholly contained and data center ready, this alone certainly opens up their exposure to a greater market.

As the old saying goes: If it ain't broke, don't fix it.  Bitfury's 55nm chip is more efficient than the A1, so why even bother with the A1 in the first place?

[raskul]

anything with 'hashfast' written on the side. 

[navigator]

Lucky for me I dont pay custom fees, and only pay $0.055/kwh average so I will make ROI very fast even at 6btc or higher. 

this reads like an offer of free hosting.  what's your address?

Lol, I honestly don't know why my power is so cheap here. It really averages about $0.08 if you take my final bill price and kwh used into account. There are also some basic fees and stuff I have to pay. My last bill was about $200 for 2500kwh.

[dropt]

If you're stuck on 55nm just sell the S1 underclocked and let people build up their 1GH/W hashing power from smaller cheaper units.

Underclocking the S1 doesn't decrease the production cost.  All it does is decrease the effective $/gh and makes them less appealing.  If buyers are stuck on GH/W then they should underclock the S1 themselves.

You need to underclock the frequency and volts together (to balance H/W errors). But really I'm saying the the new 55nm chips have the same size package so just stick them on the same boards/chassis that everyone knows and loves. It makes no sense to re-design everything into a big silver box. Just sell 100GH/100W units @ 0.5BTC. If someone wants 1TH they can buy 10 of them for 5BTC and you ship it in one big cardboard box.

I don't necessarily agree that you need to reduce the voltage along with clock rate to balance H/W errors, but that's beside the point.  It's not a "new" 55nm chip, it's the same as the old one.

The S1 is not datacenter ready and not everyone wants to hum and haw about what PSU to buy and how to arrange/contain units for acceptance into Colo.  You can likely already achieve 1W/GH with the S1, but again, that doesn't reduce the production overhead so you're not going to see such a reduction in price just because the working HR has been reduced.

[klondike_bar]

I doubt you will get anywhere near 2Th from an overclock.  I think a 10-20% increase may be possible with a second PSU, but any higher than that would require both modifications to the cooling as well as hardware modification to bring up the voltage a bit

[NetTime]

Disappointing indeed.  Guess I'll hold my Neptune preorders.

"Bitmain is a team of technologists, venture capitalists, entrepreneurs and Bitcoin enthusiasts. Our core members have years of ASIC development experience, and have designed and mass produced several digital signal processing ICs.

We reject some business practice in the community, which is intended to distribute the risk and benefit asymmetrically.

---------------------------------------------------------------------

What happened to all this...which made the BitMain the company that we all love and trust with our money...BTC...

Now they are trying to joint the ranks of all others BS manufacturers...BFL...etc...you name it...

Pre-orders...(never, right...?),...$ price...fix configuration...no data...specs...details...no open source firmware upgrades ...no communication...limited quantities...only missing point is "shipping delays" (very fast and on time up to the moment!)...

Very disappointed...WRONG direction, BitMain...very WRONG...imho...think about your moves better...

LOL, why? With the S2 you'll get an extra couple months of mining in.

I think i'm in agreement with NetTime, i'd rather have a Neptune than an S2.

Personally I think buying a mining equipment with your earned btc is a zero sum game.
In most cases ROI is achieved when btc goes up in value against the $.
So it's better for us to  buy in  $,  if btc goes up to 40k like what
the winklevoss said, by the time you ROI your btc is 280,000$ instead of 3899$.

Argument can go both ways but if we truly believe in crypto it's always better to buy with $.
