My batch 2 has consistently run between 986 Gh and 1.03 Th/s.
And yes, half the blades were completely dislodged from the back plane.  

EDIT:  My Dragon runs at 963 Gh and never hits 1 Th/s.

[robbcarpdm]

Just to report in that my batch 2 S2 has been running flawlessly at 1TH/s for 5 days now.

Me too. It appears that we're in the minority though.

One running for 24 hours solid so far.

Batch one buyer here and yes I have buyers remorse I could have had a dragon at $600 less and given the quality issues....all bitmain had done is give us $100 coupon on another.....

Heck they could toss 10 USB ants as it I woudl have been happy...

Had a miner die, it was a power cycle issue and had to get new SD card yes its only $16 but the time wasted just ticks me off more.

Now Bitmain is offering $3100 when you can get a dragon for $2750 in less time......  sorry Bitmain isnt worth the premium even with the new CALL for Warranty Service they are adding.

Sorry Bitmain you just lost me as a customer.....I  ambut a small fish only 4 TH total.......but this was as much poop as buying an Avalon Clone from a nobody ....and you have done nothing for the inconvenience even though you know about the issue.....

Not too worry there are still enough newbies to piss away their money you will probably sell out your Batch 3 but it wont be me......

Stock volt regulators I wont go over 212 mhz......best HW error to GH at pool improvement per my buddy you did his.

Cheers,

ROI is possible if BTC reach USD 850 and above.

Why not just buy BTC then?  You'll make a better return.

The cost of the miner in BTC goes down as the price of BTC goes up. That's why it helps ROI. On batch 2 the BTC price was dropping during the sale period so the ROI got worse the longer you waited to buy.

That's just normal variance because of stales, rejects, HW errors, etc. You're not a noob. You should know this stuff.

people need to stop looking at it this way.  it just doesn't make sense.  the machine mines btc not fiat.

capital investment in btc, return in btc.  If it doesn't make financial sense looking at it this way, factoring in fiat exchange rate to make the investment look better is bullshit. The "improvement" in the return because you include the fiat exchange rate of BTC, doesn't make the investment viable.  You may as well skip the hassle of buying and maintaining the hardware and avoiding the electric costs and simply buy the btc and sit on it. This is what I believe is the number one mistake newbies (and some not-so-newbies) make when they are calculating the return on their btc hardware.  The one and only reason I bought the hardware is to continue my involvement in the btc community and support decentralization of btc mining.  I just wish that it didn't cost so much to support my habit. ASIC manufacturers are making a killing selling this stuff to people that think they are going to find gold (ala 1849).  Again, I have to emphasize to everyone thinking they are going to buy hardware and make btc, the risk of the unknown future difficulty is not worth the measly return you think you are going to get but more likely probably won't. If you want to support the bitcoin network, buy bitcoin and spend it on things you normally would buy with fiat at vendors that accept bitcoin.  This will do more to support bitcoin than purchasing a piece of bitcoin mining hardware.  If you realize you won't make a return on your hardware purchase, but are buying it to be involved in the community and support the network, etc, etc.. then go ahead and buy one.


Disclaimer: I am an S2 Batch 1 customer and I do not expect any of the S2s I purchased to ROI. I paid a bit over 6BTC per unit. I don't expect the hardware to make more than 5.75btc/unit before the end of October, by which time the amount of btc this generates will be miniscule.

You are confused. What I'm saying is that the machine is priced at $3200 on the web site. If you were to order it today at a USD/BTC price of about $500, you would pay about 6.4 BTC. If USD/BTC goes up to $1000 you will pay 3.2 BTC. Paying 3.2 BTC is much better than paying 6.4 BTC.

I paid 5.5 BTC for batch 2. Others who ordered later paid a lot more (in BTC). I may ROI if I'm lucky and everything goes perfectly. They won't.

I've been running mine at 1080 gh/s for over 24 hrs now and it reports that both on the miner and at the pool.  overclock to 1080 gh/s by following:

if you do the following the config will save even through reboots:
1. have 4/10/14 firmware
2. ssh into miner (user root, password admin)
3. cd /config
4. vi asic-freq.config
5. comment out current stats (place a # in front of lines that dont have it)
6. add these:
        option 'freq_value'    '0801'  #212.5M
        option 'chip_freq'     '212.5'
        option 'timeout'       '40'
7. save
8. you can either type reboot or you can go to the web interface and click save on the miner configuration page.

posting again so it will be at the top of the page:

Is BTC6.5 bad investment for batch 3?

Is BTC6.5 bad investment for batch 3?

I estimate 1T currently making 0.065 means 100 days to breakeven before difficulty increase or electricity costs.

No go.

S1 @ 0.831 for 180G makes 0.0125 or 67 days to breakeven.
Risky too but possible.

With free power you definitely want to go with S1s instead of S2s. The biggest advantage of S2s is lower power usage at a much higher price per hash.

Bitmain won me over with the S1.  I have one batch 2 S2.  I will unlikely pull for the batch 3 S2 unless the price comes down.  There are alternatives.

With free power, you can stretch your investment longer than almost everyone else.  But "free" might not be free anymore if you are drawing large amounts.  Someone will likely notice eventually.

In 65 days the dificulty will increase from 6.9 to over 20+ Billion.  

After the 10 Billion mark in 2 1/2  weeks the miner is only making .0025 btc per day before the next jump.

I have the following running currently;
10XS1
1XKNCMiner
5XBE Blades

My problem is that I've run out of power available. I can't even OC anything without tripping switches.

So if I replace 3XS1's with 1XS2 that's 540GHs out and 1TH in. I can easily sell those 3 units and make some money back in fiat.

It's a large commercial building and contract has power included. Plus it's unmetered. To top it all, I have very limited power available as you can see above list maxed out my electrical consumption. So it's not necessarily a giant farm in hiding.

Sounds like a dream for a Bitcoin enthusiast.  Wonder if you could bring in an electrician to add another panel or two and expand your "free" power (although that may require a transformer upgrade, which can be pricey).

By terms of my contract all electrical work has to be approved by building management, which will give away my hunger for power
