ANTMINER S2 Discussion and Support Thread

[claudesdad]

I couldn't give a rats ass about nanometers or "sexy" miners (seriously you guys need to get out more). All I care about is price, delivery, reliability, hash rate, and power usage.

Have to agree.  "Sexy" looking miners that don't ROI aren't going to pay the bills.  And women don't pull their clothes off because your server looks "cool".  They pull their clothes off because your miner is filling your wallet with BTC.

Exactly. This guy is doing it right:

1. Exposed circuit boards and fans? Check.
2. Repurposed ATX power supplies? Check.
3. Miners that ship when ordered and ROI? Check.
4. Rat's nest of power and ethernet cables? Check
5. Girl taking off her clothes? Check.

All she needs now is an Antminer t-shirt.





How are the S2s coming BITMAIN? Any updated pictures for us? Some information on the number and fan types would be useful as well.

Regarding the PSU, I contacted Enermax to inquire about the ERV1000EWT-G. I asked:

(1) What is the expected MTBF for this PSU if placed under a 85% or 90% load continuously?
(2) What is the maximum recommended continuous load for this PSU?

This is the response I received:

1.     We do not have figures for MTBF at 85% or 90% load, but similar calculations show that at 100% load, the MTBF will be 42% less than in 70% load.

2.     1000W.  Yet please note that the best efficiency of this power supply is at 350~600W load range.  If system is constantly run at 800~1000W, we recommended to use 1500W PSU for best power consumption consideration.

Of course, the one caveat is that I do not know for sure that this is the exact model of PSU being used in the S2.

42% of unknown is still unknown

Did they say what the MTBF is at 70%?

Boom, mine now shows as paid.  Thanks Bitmain!  I wasn't kidding about that T-shirt doe

Got 2.

I will assemble all my miners in them.

pics or cryptographic proof.  Those are the only things I trust.

Sorry it's creasy, I was at work yesterday.....

Edit: Sorry I don't know how to make small pic.

In the past few days, the blockchain.info API stopped working and we cannot confirm all the transaction until yesterday. We had to manually confirm some of the orders, but the man hands' speed could not be compared with computer, so lots of order were delayed in shipping. We feel sorry for what happened, and we are deploying the second payment API, and our private payment service is planning.

We will adjust the price of the S1, and starts to sell Batch 3 of S2. All the orders which is influenced by above accident will get coupons.

Yep pretty much I agree with you ... Spondoolies-Tech made some beautiful 1.25U 1.4TH/s miner ($4999) yet you will never make your money back on that machine especially next batch is released early May... Bitmain, if you can lower prices even more you will beat all competition out of the park again.

This is why I buy all my gear from BITMAIN.  Proper communication and exceptional customer service.  Bravo.

how did you snag a bitmain shirt? I have ordered ~15 S1 units this year and no shirt lol

 A dozen Antminers and no T-Shirt I'll have to ask for one when I order one of these fancy new 1THs rigs next month

Shouldn't they say more instead of less ? Running 100%load with 42% less failure than running 70% load ?
Doesnt feel right ?

Time to failure is 42% less, meaning that it will fail a lot sooner than if running at 70% load.

i knew i bought the right miners!! they are running great .. now i am just waiting on all the hot babes to show up!

42% of what 1 minute or 1 century, or the time it takes for....

If it is 1 century then I would not care as I would most likely be dead, if it is 42% of minute then I would be a bit pissed.

I agree, but I would add one more thing. Size, if two machines are equal in everything, but one is twice as big as the other, I will take the small one, please.

Obviously, I don't have to agree with you 100% (except for the part that I should get out more).. but you're right on the money with that fact that the ASIC doesn't need to look "pretty". To get the job done is the right attitude and it's not like we'd look like poster boys ourselves either.

Furthermore, it left me thinking about the 1.25U competitor.. If they consume between 1.2 - 1.35kW power, why bother with such a small factor (and risk with not being able to dissipate the heat effectively, hence more noise for fans spinning at max)? Yes, it is the coolest looking kid on the blockchain, but as most Data Centers can normally only facilitate up to between 8 to 12 kW of power per rack (including the equivalent in cooling), where lies the benefit in 1.25U when you can only fit 10 of those into a 42U rack maximum, leaving 70% of the rack unpopulated from a density point of view? Data Centers that could facilitate more power are few and far between.

In this sense, BITMAIN seems to be spot on with the sizing - but it does come down to the price and how well they can position themselves on the market. No doubt more competition is coming and the big names of the past are looking to regain their position.
