ANTMINER S2 Discussion and Support Thread

[seriouscoin]

Come back from easter break to find one machine completely unresponsive. I've isolated the PSU, given it an hour or so with no power, checked the paper clip short, still no luck. I seem to remember someone saying to drain the PSU you short the two power pins out, still nothing.

I have a Corsair CX750M and a FSP 750 Gold, can I just plug these into the PCI-e power sockets and combine them or does it just not work that way?

Another machine was running at 50% hashing with lots of x hardware errors but a shutdown has that back up and running stable.

Still waiting to hear positive confirmation from the Bitmain engineer/s regarding 2x 700-750w PSUs.

2 x 650/750W server style PSU should be ideal...even redundant...and cheaper too...IMHO...

But this is their product/design...

Its not redundant unless the device can run with one PSU working. That would be 2x 1000W+

Are you telling me, hes a failed arm chair engineer?

 

LOL the dude claimed to be a computer engineer and criticized Spondoolies's strategy,

Bitmain is the only choice for Bitcoin Mining


Why do I say this?

I have purchased 267 Antminer S1's. Out of 267 S1's I have had 1 problem unit. One unit with a dead ASIC blade. That's it, 99.8% success rate. That's unbelievable. They just keep running, and running smoothly.

I have purchased 27 Antminer S2's . Out of those 27 S2's I have 1 blade that only half worked (From batch 1. The heatsink had a burr on it that cut into the board and shorted out half the blade). I also had 1 power supply that melted as the cables weren't connected tight at factory. While batch 1 had a good amount of extremely irritating issues, batch 2 was much better and batch 3 was nearly flawless (A few loose internal cables). I have been in contact with Bitmain concerning all the issues and they are indeed working to correct where they have come up short.

I have no doubt the S2 will soon be just as rock solid as the S1, and as you can see form above, the S1 is gold standard in ASIC hardware.

I'm just getting tired of refreshing their website whenever I can several times a day. I know B3 will last 5 minutes and I will miss out.

I'm certain it will last more than 5 minutes unless they are charging like 4 BTC for it.

The thing is, I don't really care about Bitcoin/USD price.  I got my S2 for 5.5 BTC, so they would have to price it at $2750 or less for it to be as attractive as when I purchased it.  I probably wouldn't purchase it for anything over $2500 though.  Especially since 5 S1's would run about $1800-2000 after a couple coupons and $2100 without.

Not to mention S1's JUST WORK.  No bullshit.

Edit: DON'T really care about etc etc.... lol

How in the world did you get Batch 3 when they haven't released it yet?

It was more like a batch 2B but people are referring to it as Batch 3.

He claims to be a C.Eng of like 35 years, or is 25?  Either way, just read his posts, nuff said.

That is crazy. Are you still mining with all 77TH? Do you personally own all 77TH or is this hardware shared as part of a mining group?

I have 20 S1s mining right now, and all work flawlessly, so I hope Bitmain addresses the S2 quality issues and offers a new competitively priced batch of S2s soon.

Bitmain not only offers a great product at a fair price, but they are also putting an end to a lot of the shenanigans pulled by other hardware manufactures by forcing them to alter behavior in order to stay competitive.

Just say no to pre-orders!

That pretty much sums it up right there.  Quality control issues with the S2 and general communication issues aside, they're the only miner manufacturer that ships from stock at a decent price.

They changed how us, as customers, view all companies.  If they don't ship within days and the price doesn't lower with the current BTC price, we immediately get turned off.

The 5 or 6 month waiting period or longer is no longer acceptable as industry norm.

Now if they could have S2's in stock and lower the S2 price like they do the S1 price.

Guys!

I have only one question for all. English is not my first language but hope you'll understand.

The question is simple.

At the last few months, what kind of asic hardware could you buy off the self?

Other one.

How would you mine without Ants these days to see some profit in BTC?

Mining on most of it. Bought some for family/friends

S1 is a dead product already.
Sorry , but with 2.1w/Ghs is a lost case.
I wonder who buys it today.

I would not go with S2 either.

I would buy an A1 clone for much, much , much less.

Best to use too identical PSUs if you are going to try as they you DO NOT WANT one PSU to become a current SINK of the other PSU due to lower reference point....IE lower ground.

I'd buy more for the right price. The w/Ghs vs $/Ghs varies from person to person due to specific environmental factors (temp, kwh price, etc.). Here in TX I pay .09/KWh so 2.1w/Ghs isn't that scary. Especially since you can undervolt to something more reasonable. But if I were in California (i'm from Cali but don't live there now), it would be a TOTALLY different story (up to .32/Kwh in Cali).

So if you have any S1 miners you wanna sell because your power is too expensive Pm me! Because mine aint.

antminer s-1 under volts to 150 gh at 200 watts

 this make it viable for an extra month.

I see you did post in that thread.

Yes, thanks for your comments.

I am not saying to throw away your current inventory of S1s.They are just non competitive anymore to buy.

The clones have gone as low as $2200 (or 4.4btc) for 1Th/s, and power consumption for 1w/ghs.

in order to achieve with S1s the same result, you need 7 units which will cost at least 6 btc. Add the psus and wires ( and still make a ratio of 1.2w/ghs).
This is not viable.

Also the pencil mod cannot work forever, it needs to be redone every now and then, because of various factors ( humidity, oxidation, etc)

If you want to baby sitting so many machinery just to maintain a single terra , then ok.

I will stick to the clones, more possible to make a ROI.

[freebit13]

Congrats to all those who've received their batch 2 miners, I'm still waiting for mine. A 10 day loss of income, which is almost 1btc, is quite a disappointment. I just hope that I don't have as much trouble getting it up and running as some of you on here.

 

[solitude]

Hey Bitmain, how about you stop selling miners that will never ROI to retards who have to have the latest bitcoin miner?

I understand basic economics, but just because there's retards willing to buy somethign doesn't make something right!

The truth is that there will be never ROI with those miners.

Bitman, any compensation?

Thanks.
