Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 288. (Read 528055 times)

Yes, I thought it was "quite cool" as well, Aries.  I'm impressed with the noise factor as well.  Sounds to me about the same decibels as the S5.  My IBM 2880W PSU's are louder than the S7.

What PSU are you running with? S7 needs a solid 12V, ideally 12.2V when under full load. If you have a multimeter check the voltage actually getting to the PCIE sockets.

I've been having issues with my review copy S7 the last day or so, with it not getting even close to the advertised 4.86 TH/s.

I've tried the following:

-reset the miner to factory settings
-physically turn off the miner and turn it on again
-restart it in the software (tried this about 7 times)
-downclock it to 575 MHz as well as 593 MHz

I'm getting fairly high HW error rates (at 593MHz I was getting 2% HW error rates, about 0.2% @ 575MHz) and low hashrates (between 2TH/s and 4TH/s) - I was reading through this thread a week or two ago and noticed others had similar issues, did anyone ever find a fix for these problems?

3 days, 16 hours for me with 2 units:  4854 and 4845.

I am rather surprised by the volatility though.  Here is a chart from BitcoinCZ with my (2) S7s, (3) S4s, and (1) S3:  http://puu.sh/kOKPC/e46870370a.png

lets say you use f2pool  they charge 4%  but they toss you some NMC  this drops you to about 2%

they pay on time every day 1 time a day.

so now they pay .00792982 per th

so a s-7 = 4.8 th

so they pay you 4.8 x .00792982 = 0.038063136 btc  every day and  7x that in NMC that is 0.266 nmc a day

so your gear will earn

0.03806 btc
0.00037 btc = the free nmc they gvie

0.03843 btc total  each day every day    when they send it to you the charge is 0.0002 so your net is 0.03841 for the s-7

each and every day. 

1) Both will yield roughly the same result IN THE LONG RUN (minus the fee). PPS pays per each share you submit to the pool, PPLNS pays per N last shares when a block is found (where N depends on the pool) so PPLNS payouts depend on pool luck whereas PPS payouts don't. Whether having a steady stream of BTC instead of ups and downs is worth the fee - that's up to you.

2) Depends on your power costs. Use a calculator, e.g. https://bitcoinwisdom.com/bitcoin/calculator

About 0.040 BTC per day

Hello once again.
Im a newbie in this scene, but already purchased a S7.... not delivered yet...

I've got 2 questions (doubts).
1) What kind of payment should i use: PPLNS or PPS.
I know that PPS has a fee, but is it worh it?

2) For people already running a S7 24/7 day, How much BC/day are we talking?

Thanks.

With the Bitcoin being so favorable, I went ahead and made another purchase of another S7 B3.  Hoping this time I can get one that runs 4.8th/s.  I already have 5 S7s that wont touch 4.8th/s.

I'm thinking someone got told to go in and work on it.  The website is now up again.

I don't see anything really different after a quick glance.

Very Cool dmwardjr!!!  All at 4.8th/s---Very Cool!

No, its a Sunday so no one is on.

Your are absolutely right brothers think positive be positive

Well said, Questor.

I'm getting tired of people using the word, "Chinese," in such negative connotations.  Can't we all just get along without negative denotations regarding one's ethnicity?  It's completely unnecessary and profits no one.

Bitmain, truly has been supportive of the home miner and those who aspire to have larger farms.  This is not a perfect world and everyone [Including corporations] are not perfect either.  We might find Bitmain more generous in their dealings with us if we would be more supportive in their contribution to our community.  Railing at them in this forum and emails serves only to divide us instead of unifying us as a community.

So, let us chill with the negative connotations towards one's ethnicity and learn to get along with each other.

Cheers M8

One would think.  I have not tried to hit up any BM contacts.  But it is China daytime now.

Do you have any idea why they are down?

padrino,

touché - I do not know the backstory, but none was offered, so yes, it may have been a bit presumptuous.  I would state however, that the negative and off topic nature of the previous whiny posts and vague allusions to the fact that the employer did not know about the power usage did not seem to indicate that this person was one of your employees that had been given the right to use 'free' power...

Had that been the case it seems that "my employer provides it knowingly" would have sufficed.  "a facility I have full oversight over" seems to indicate the employer is not aware that power is being used to mine bitcoin to the sole benefit of an employee...  It also seems to indicate a bit of a haughty attitude with respect to the nature of the question.

Anyways, I suppose thedreamer could have cleared all of this or clear it all up by just stating whether or not it is known that their power use is for personal bitcoin mining.

There have been lots of discussions over the years about 'free' power and the moral implications, so when 'scruples' were mentioned, things became interesting...

I also found it ironic that the poster mentioned something complaining about no oversight, when apparently they are the oversight at their facility, but are potentially using power there illegitimately!!
So I was asking questions, to verify the veracity of my ironic assessment, and all indications were that of avoidance of the question.  So I did assume that by the dodging verbiage, there was no legitimate use.  And therein may lie my error in judgement, but you are correct, without any of this information, it's all just presumptions based on vague assertions.  I will apologize if I am in error.

Generally speaking though, why should anyone ever generalize a whole country of people, especially those one is doing business with, with insulting and degrading speech such as that?

Bitmain has been kind enough to supply us with what is presently the most energy efficient mining hardware available, and sure they are having some hiccups, but those who have received miners in this thread are a testament to the fact that they are trying to get us product.

As mentioned, nobody else is... So can we stop bashing the Chinese as a whole people  / Country in here and concentrate on the S7 miners?

Well aren't you just the cool cat POWER THIEF, daddy-o...

I'm not "trying" to understand anything about your "hook-up",  I comprehend fully well that you are a self-admitted thief and probably a felon, though you have not been convicted at this time.

For someone who said:

Isn't that a bit of the pot calling the kettle black?
So, "nature" provides electricity to your miners for free?  Miners here all run on coal / hydroelectric / wind / nuclear power through a built and managed infrastructure and power distribution grid which we pay a fair price for.

It is sad that you cannot keep your bigoted, nationalist, and criminal self restrained enough to avoid posting gross generalizations about a billion people whom you don't even know, and sadder still that you have self-evidenced to be no better than that which you complain about.

-------------------------------

So, I had one of my S7's unexpectedly reach critical temp (got to 85C per miner status!!) and stop mining, but only on one board, and it was string one, which seems odd as that would tend to indicate that it was one of the outside ones.  I would think that the inner board, being nested in between two would typically be the hottest board...  But maybe they aren't in order?  Or maybe this board is just generating extra heat because it is of borderline press quality?!

Anyone else get a thermal event yet?

I did not want to take up space on this thread with multiple screenshots of the "miner status" of all nine S7's.  Here are the results after 24 hours of use.  Look at the "average" [GH/s (avg)] hash rate at 4.8+ TH/s.  Look at the HWE% as well out to the right of HW in their proper columns.  I'm quite impressed.  You can click on the screenshot of each S7 in the link provided to maximize the screenshot then click again to minimize.

Nah, it's not a manual process (although with the amount of delays in shipping it might seem like it!  )

Or, they could have taken the site down to fix everybody's shipping status. If it's a manual process, it will take much longer depending on the number of accounts with wrong shipping status.
