price is still to high

S1s are now about $200 a pop. For those who are math challenged, that's $1200/TH unpowered or $1560/TH stock with ATX golds.

Bitmain!!

I have received a very smashed up Batch 3 S2 unit from you! I have sent you an email with the details but no response yet. Please look into this ASAP, I expect a very swift response as I'm a customer who has bought 30 S1's and 2 S2's from you! It was purchased from the username "B4rtab".

I expected you to resolve this issue after Batch 1&2!!!

...and the price is still too high

Edgar today S1 price $224.12  for one AntMiner S1 is by far the best priced miner in the market.

Problem is not hardware price my opinion is BTC is to low now.

Just for a comparison.......Microcenters, an electronics retailer announced today they are selling mining equipment. Right now they have Gridseeds and Antminer S1. They have the S1 priced at $400.00, (gulp).....

Holy crap, would you look at that:

Bobsag3 must be happy about that.

They are going to have to change their refund policy on these. What's to stop someone from buying one and bringing it back in 30 days for a full refund?

I appreciate what you're saying but the BTC price is down to all of the mminers desire to buy/sell (including the HUGE data centre miners)

whereas the price of the S2 is solely down to Bitmain.

I agree the S1 is at a reasonable price but the power consumption is just too damn high - i cant justify using 5-6 x 400w (plus PSUs) to get the equivalent hash power i can get from a single 1000w S2 (which comes with a PSU)

but yes, those BTC dumping douches are not helping wrt the price of BTC either but we cant lobby them all into 'hodling'

whereas we probably can get bitmain to sort the S2 price out - though im sure he has a long term strategy to milk them(us) for all their worth, incrementally.

Yes milk.   As manufacturer they have alot of room to play chess with the other players.  But noone want to go to low.

[freebit13]

Bitmain took the massive risk of investing huge sums of money to produce some of the best-selling miners on the market and supported the bitcoin community by not accepting pre-orders and they are competing right at the top now. I believe they might have the right to set the price as high or low as they like.

I doubt they will be willing to make a loss, just because a few people on this forum think they're entitled to cheaper products. Remember that they still have to pay their suppliers and staff in fiat... I'd like them to stay in the game.

[descarte]

I like the 1T

but

please dont reset everything upon rebooting, also basic packages like cron should not be removed.

Sorry to say but price (including costs of PS) and power consumption is not the only means of comparison for product value between S1<>S2.

When Bitmain can also make the S2 as reliable as the S1 and ship it in working order to customers with a lower sale price then I will take notice.

S1 is awesome;  Bitmain should think about moving to 28nm or 40nm in the same great form factor for ~400-500 GH/s and =<1w/GH.
That would be a killer product up to $400-450. Call it S3.

IIRC there was already rumour, or an outright statement by Bitmain that they've got a 28nm in the pipeline.

IMO Bitmain has done themselves a disservice by trying to build a 1TH miner with their existing ASICS.
As an EE and embedded software engineer I see these problems:

1. Bus based systems using card edge connectors - unreliable (see original IBM PC)
2. Beagle board is hobbyist grade - unreliable, known for SD card problems
3. Too many ASICS - unreliable
4. Shipping problems because of #1 above.

The S1 is rock solid because it was designed that way.

1. Two blades solidly attached to a metal frame and connected with ribbon cables.
2. Commercial quality controller in the TP-link

I assume (hope) Bitmain cobbled this together as a stop-gap while they ready their next gen ASICs.

[tzortz]

Until then, there also nice gear with 40nm and 0.7w/ghs for less than $2150 per Terra.

Gear that works right out of the box, no need to assemble your broken miner and no need to get a better PSU.

Bitmain responded to customer demand.  Quite a number of people had issues trying to colo the S1 because of its form factor and expressed a strong desire for a contained 4U 1TH unit.  They (Bitmain) delivered.

As per your other points:

1.  I agree that there are and were issues with card edge connetors, but the industry still uses them at large.  Manufacturing and electrical component characteristics have come a long way since the 70's and 80's.

2.  I agree.

3.  Greater number of chips allows for redundency.  You can have a single ASIC fail in an S2 and be okay, if you have a Cointerra or HF unit and a chip fails, that's a large percentage of the machines achievable hashrate and would warrant an RMA. In the world of Bitcoin mining an RMA is a death knell.

4.  The shipping issues aren't a result of the card edge connectors, it's a result of deficiencies in the mechanical design and packaging.  Computers ship all over the world everyday with card edge connectors in place and arrive just fine.  IMO there was inadequate support for the guide rails, poor clearances (loose) between card edges and guides, and no mechanical lock securing each card.

I still think S2 is the best option in the market considering the available options.

Is there a way to get these beasts warrantied through bitmain?

Last time I asked for a refund of 6BTC bitmain said I was "trying to social engineer them"  and threatened to post the request to the forum.

So I'm assuming my customer if F**** if the control board is dead/dead/dead on the S2?

Anyone have ideas?  Writing 100 more SD cards doesn't seem to help and I don't see a meaning to all the different lights to help figure it out.

I am an owner of many Bitmain products.
I was about to order a few more S2s because they were the cheapest per Terra machines at that time.

But to be honest I got sick of babysitting , writing and changing SD cards with the S2s known issues.

Now , the cheapest is the SP10 , a solid machine. Reminds a modernised version of the reliable S1.

Thank you Roadstress for your group buy.
