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.

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

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.

ROI is possible if BTC reach USD 850 and above.


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

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.

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

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,

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.  Shocked

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

This brings me to my bigger issue: I cannot seem to remotely access the web UI for the miner.  Remote use of PUTTY works fine and I had to use that when modifying the pool info.  But when i go to 192.168.1.99 i get a login page where root/admin and root/root do not work - eventually dumping me with a 401 error. The login window is identified as the antminer machine so is the correct ip address.

I can forgo the webUI since my pool sees a constant 990GH, but it means I cannot do the simple save-and-apply method. I need a SSH-based method to apply the change, either via 'reboot' or some start-cg/stop-cg commqnds
I've had that problem, it's probably because you are accessing a cached page from an old S1 which has the address "http://192.168.1.99/cgi-bin/luci" as opposed to "http://192.168.1.99/index.html". Try using the second link to access the gui page or clear the cache with ctrl+F5.

ASIC Wannabe

could you please post a code for overclocking? I havent seen the method laid out clearly and simply yet.

Code:
code window

I think the voltage of the regulators is the issue, rather than power or temperature.  I have a pencil and a 2000W PSU ready, and am hoping to spend some time with my device tomorrow to see how easily the regulators can all be pencil-modded. 40 resistors total that will need to be modified if you want to get the frequency any better than 225

I have not done any pencil mod on the resistors only adjusting the asic-freq

Code:
ssh root@(your miner) - pass = admin
vi /config/asic-freq.config

#option 'freq_value'    '0881'  #225M
#option 'chip_freq'     '225'
#option 'timeout'       '45'  <--- I have changed this from 50 - 40

option 'freq_value'    '0781'  #200M
option 'chip_freq'     '200'
option 'timeout'       '40'


presumably the timeout should decrease as frequency is bumped up. I would assume 42-44 would be a good zone to try at 225 and even at 200.

after the above edits to the file, how do i implement it? Do i have to restart cgminer, use the reboot command, or actually switch off the PSU and switch back on (after a few second delay)?

I am all set to install the 2000W supply tomorrow - and will try overclocking moderately when I do. Does anyone know if there is a hex code that provides a frequency around 215-220MHz?

At my machine for stock clock, the stock timeout is 40.

After you edited the config file and saved it, just go to miner configuration and psu save and apply. It restarts cgminer with the new settings. For me his is the best working way.

If I always switch on-off the miner sometimes it brick or reset back to default.

In hex codes I would be interested too. I've tried to figure out some but had no success....

Haha RoadStress you must not remember me.  I forget to mention Spondooodaloodaroodle.  I was the one you offered your "deal" to.  I still want to take it kinda, but I'm so allergic to preorders Sad

Sorry about that! Offer still stands though Smiley

Where do you see an SP10 that ships this month for $3000?

In my Group Buy: https://bitcointalksearch.org/topic/m.6278748

@smooth Still 7 days left. I still don't understand people who think that diff will up forever with 20% considering the amount of miners that are being sold right now...

Bitmain - we have had a great relationship for the past few months.  Sadly, it looks like it's ending.
You are no longer competitive given the S2's fragility and high price.  There are better options that are built more solidly and don't cost as much.
But I'll keep watching.  Hopefully you come to market with a product as great as the S1's were for their time.

+1000

You are going to loose a lot of customers if you keep this up.

+100 BTC...just kidding...second this though...

SP10 is $3000 + shipping...for 1.4T...
A1 Clones...Dragon...and siblings...1TH... are @2300 + shipping...

Far away from $3,199...IMHO...

Where do you see an SP10 that ships this month for $3000?


Call them ...e-mail them...ask them...SP-Tech...research...and you will find... Wink

RoadStress could help too...

EDIT...: MAY delivery...

May delivery is 8000 for two units. 7200 if you can get a 10% discount as a previous ASIC buyer. The 3000 group buy price is only if the group buy gets above 700 units. It's not even at 300 yet, but it could still happen.

If you look at s1 and s2 thread its stagnation for them. s1 thread is dead. People realise that asics are way overpriced.



I try to see it from the other side...

Btc is underpriced...

0.831Btc is 404$. About 100$ shipping because it's heavy. I'ts 304$ for the machine. They pay for costs in fiat not btc.

Think again the situation with 1000$ btc price...

Hope know what I mean

So buy the BTC then and save the wasted $100 used for shipping and no electricity or setup costs. I love mining but at these prices its just not worth the effort.

They can't go much lower because under this price is nuts...

S2 is overpriced for sure.

This time better buy BTC then buy asics priced in fiat.

And my small secret what I do. I'm just collecting the Btc now, wait until Btc price is fine, then buy a shitload of asics priced in fiat for nuts....

Too true, loved the S1, bought loads and they ... well ... just work (as did the price when I bought them).

I was excited when the S2 was announced, but as a rule I don't buy version 1 of anything before seeing some feedback on it. Missed out on batch 2, but my money has now been spent elsewhere on ASICs.

TOO many horror stories I'm afraid, and I don't have the time to baby sit my miners. Price also comes into the equation of course, and right now a lot is happening ... tides are turning ... different offerings are available ...
