ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[Biodom]

So is that a right choice to buy http://www.frys.com/product/7590536?site=sr:SEARCH:MAIN_RSLT_PG for S7?

I haven't seen S7 personally with my naked eyes, however I am sure 10 x 6 pin PCI-e connections has to do with connectors.

It appears to have ten (10) 6 pin connectors for PCI-e ports.  It also "says" it is 12 + Volts.  As long as it's 12 and not too much less, you will not have to be concerned about hash rate or HW errors.

Thank You dmwardjr,

You made my day. I will wait for my S7 to arrive. If this PSU + S7 works, I will add more hardware in future.

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

this is simple if you want $, then multiply your energy cost (+transmission fees)/kwhX1.21X24=daily cost in $$
You will be using 1.21 extra kw/mo per miner.
Hopefully, you are not in CA or NY.

people are being surprisingly nonchalant about it.
...I woke up at 3am this morning and at first could not figure out why.
then i heard a tiny noise coming from s7 (much less than s5)
;run to it, Internet is down ("internet not working well" situation)
miner is still doing something and fans are on very low, and air is coming out quite hot.
Thankfully, I had a Vornado fan blowing into intake for such situations and to help with cooling, so no critical overheat occurred.
Internet came back within 2-3 min and it was back to hashing.

all i am saying: beware and try to adapt. i can practically guarantee that it WILL happen in large hosting because usually service guarantees just 98% uptime.
If service loses internet, but power is on....

I'm curious...  Did you already have the October 23 Firmware update on this rig?

no, i didn't, as i usually wait a few days-this saved my hide a couple of times when upgrades were bad.
upgrade might help, but it seems that it is a problem that migrated from s5 to s7 and if it was easy to fix, they would have done it long time ago.

I have a question about manual fan speed setting.
If you set it to 90% does it stay 90% even when the internet goes out? Or does it cycle down and back up to speed?  That would be great if it just kept up speed.

Kind reminder:
When mining with S7, be sure that you've connected the internet properly and the internet is working well, otherwise, the boards may get burnt easily

I would not take this seriously. This message is not from Bitmain.
They would have used proper channels, and not post a poorly written post on a forum, with an unknown username, lol!

It is a Bitmain account, Janet's successor as she is off doing other things. I've asked them to add it to the BITMAIN signature.

how can we make sure that "internet is working well"?
"oh, no, your miner boards got burned....you did not make sure that internet worked well".
I understand that he means well, but this is just impractical, seriously.

Yea that is a bit unnerving considering no ISP is 100% guaranteed and even my home router needs to be bounced once in a blue moon.

see my old posts in this thread. I wrote here about it but nobody wants to hear me. Photos of burnt S5 are in the thread of the picture your mining... only one time fall me internet connection..
 I am skeptical about s7 if bitmain no fix this dangerous FAIL. One mistake and you lose 2000usd(miner+psu+tax). If you put them in the data center, you are waiting for nearly a year return on investment.

Well, I hope this fixed it.  I guess we will find out from someone soon enough or we never will find out which means it fixed it.

Damn good idea.

I'm not willing to disconnect the internet to find out.  I would have to take one rig away from all of the others to listen.  Why?  Because without internet, we could not log in to it to find out.  We would have to be next to it away from all other rigs to listen to the fans.

I'm not willing to disconnect all 9 of mine to find out.  I don't have 240 anywhere else in the house with a NEMA L6-30 outlet.  I suppose I could do it with my corsairs at another location.  I'm just not willing to disconnect to find out.  I'll see if someone else does it first.  If they don't, then I will.

I saw it.  I just never responded to it.  I'm going to find out if it fixed it one way or the other fairly soon if no one else does.

Dmwardjr, have you played with the manual fan settings?

Not yet, I've left everything at factory settings except the pool information, the name of the rig and it's password.

I probably will get a couple of Corsair AX860's in another room plugged into 120 Volts and check it out to see if the fans stay at 90% after I disconnect the CAT6 cable from the controller.

EDIT:  I have a 50 feet ethernet cord to get the S7 connected to the switch from another room.  I need another room that is away from the other S7's to be quiet enough to listen.  I have not run any other CAT6 to jacks around the house.  I use wireless everywhere else.

[Mikestang]

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

It's easy to figure out.  You know how many watts the S7 uses.  Multiply that by how many hours per day you will mine with it and divide by 1000, that is how many kilowatt hours/day you will use.  Multiply that by 30 and that's how many KWh you will use in a month.  Multiply that by your electricity rate and that's what it will cost you to run an S7 per month.  Omit the x30 step and that will give you per day cost.

For me to run one 24/7 for a month it would cost = 1.25KW * 24h * 30d * $0.30 = $270 a month.

My daily cost would be = 1.25KW * 24h * $0.30 = $9 a day.

That's also why I will never own one.

[dmwardjr]

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

This calculator does an excellent job figuring it out for you.

Device name is not important:  I put "S7" anyway.


Enter in the number of watts with NO COMMA'S:  I put 1,210 as an example WITHOUT COMMA'S.  You would put 1210 watts WITHOUT COMMA'S if you are running only one S7 at stock settings.  If you had multiple S7's, multiply 1210 x the number of S7's you have.  Don't forget the watts of your box fan(s) and/or exhaust fan(s).  They burn wattage as well.  My peripherals, such as my 48 port TP-Link switch, router, modem, etc... uses a very small amount of power (watts).  So, I did not bother including peripherals.


Enter in the kilowatt hour cost:  My example was 0.034 [Which is 3.4 cents per kilowatt hour]


Enter in the number of hours each day the rig will run:  I put 24 hours a day in my example

Can someone explain to me why are there 3 firmwares on BM site for S7:

600M 4.86TH/S
575M 4.66TH/S
550M 4.45TH/S

Can I use any of these firmwares on any batches of S7?

Example:
I have B2 unit can I put 600M firmware on it?
or I need to use 575M firmware?
what about 550M which batch is that one 

[sloopy]

I have updated my S7 firmware. I used the 600 and I have been running 600. The main unit has run a week at a strong 4.85. I previously mentioned it was unusually steady on the average, but I wasn't and still not complaining, it is odd.
Anyway, I did not remove the checkmark to retain my settings. Once the firmware update completed everything looked good but my hash. It seemed pretty happy sitting around 200 ghs. I performed a cold boot, then a warm boot (as this has been my habit since I received my first S3) and everything came back up beautifully. After 10 minutes I'm sitting with 4901 on the average and  180 / .0025 on HW errors so we will let her ride for a while and check in later.

I wanted to throw my own 2 cents in here regarding the conversation to help determine cost. There are certainly many things to consider, and these guys have provided fantastic ways to help you learn to do such.

I use this as one of a few checklists when I am running through things. It helps me think of items I may not always consider. This portion in particular comes from another forum member, but I fail to remember his name and didn't catch it when I copied his list to my own sheet. I would say to use this section two ways.
1. As a specific list.
Yes you must use a calculator of some type to keep things efficient, accurate, and straightforward, and most of the time I use bitwisdom but I use theirs because it is convenient to other things of theirs I use regularly. Great site imo.
This provides you with real world items you may not think of, so use the list literally and determine if that line item applies to you.

2, Use the mindset to drive yourself in this train of thought. These items can be used to think of things which would only apply to you within your lifestyle or domicile.  Don't ignore that power bill. It can get ya. Think of what the other posters said the monthly cost for a single S7 is and be confident you want to go in. Use this list to contemplate items even experienced miners here may not consider. Also, it mentions taxes, and that is a huge decision in my opinion. I prefer not to discuss it myself, but you must consider it.

Overall, once you have the financials sorted, get your head back in the real reason you do this and figure out something fun you want to do with your fresh new S7 without voiding the warranty right away, and there is plenty to do without even touching her. Consider your mining environment. After all, that has the biggest impact along with your incoming power. What can you work on or tinker with whichever your stride which lights that fire and have fun.


So here after all this buildup is the list in its original incantation. It is not pretty, long, or at first glance all that informative, but think about where it is going and the things you may come up with that are outside the norm which may be factual items for many / most people.

"When we compare the price of mining devices, we believe we should take all these factors into consideration.

1.   Cash cost
a)   Mining device sales price. This is the most obvious cost.
b)   Shipping cost. Shipping cost is trick, different shipping service will have different shipping time, and it will influence the time cost discussed in 2. Time cost.
c)   Incremental investment on PSU
d)   Tax: Some miners will have to pay VAT or other import tax.

2.   Time cost: We can estimate the time cost based on the projected gross mining revenue during the waiting time.
a)   Time on waiting period of pre-order. You know, shipping in two weeks.
b)   Time on shipping. Some shipping methods is much slower than our UPS shipping service, and the shipping time lost usually much larger the shipping cost we can save from choosing the slower carrier.

3.   Unstable cost: the unexpected downtime will cost the mining revenue. Usually a family miner will have full time job and family members to take care of. Hosting service will let the experts do the job."
 

Good Luck

Everyone take care of the hash board failure potential.
I don't care if the guy had a low post count, he is probably right on, and I made sure I checked file integrity, I was sure I was on the bitmain site by going to my own saved link, not clicking his.
Even if you do not want to update firmware then until you do clip the wire which is the feedback from the fan to the control board. On the S5 it was the blue one, check yourself on the S7 so you know and you are confident.

Somehow, someway, people don't fry boards because of the internet dropping out. Of course I am depending on the Firmware to have corrected the issue which isn't the most failsafe and we have went through many iterations of firmware which did make things worse. However, I'm at 4821.34 with .0028 and things are still looking fine and I wouldn't have updated until I saw some people I trust do so and report positive experiences. I am not saying you should update your firmware, I am saying it has worked well for me so far, and other trusted members have said so far so good. ...But, do something about the internet-drop-hash-board-burn.

[bbOOmm]

Sooooooo ...... What order date did they ship out today?

I ordered some S7 B3's  on 10/20/2015 .... I'll probably get some hobcobbled S7 B(whatever parts they could scrape up) and receive them a day or two before they announce the S8's ....... That would probably be about my luck, plus being the first time buying absolutely new Antminers, they are bound to fook over the little newbs

This hash board burning instance if the internet fails.

What is happening? Do the fans shut down when the internet is no longer sensed? If that is the case, it would not be hard to add a separate fan controller to keep the fans push/pulling air across the boards as a safety precaution while or if they ( Bitmain ) even bothers to provide a fix.

Have to get a pretty beefy fan controller those fans pull a lot of juice. High wattage per channel.

I suspect if it is happening it is something hard to replicate.  I never could replicate on my S5, but some had the issue and was a pain for them.  On S5 I even without internet a few times never had a big issue.

On S7 it is kinda scary to hear people mention this problem.  I'm hoping it's a very small subset of machines.   

[philipma1957]

So is that a right choice to buy http://www.frys.com/product/7590536?site=sr:SEARCH:MAIN_RSLT_PG for S7?

I haven't seen S7 personally with my naked eyes, however I am sure 10 x 6 pin PCI-e connections has to do with connectors.

It appears to have ten (10) 6 pin connectors for PCI-e ports.  It also "says" it is 12 + Volts.  As long as it's 12 and not too much less, you will not have to be concerned about hash rate or HW errors.

Thank You dmwardjr,

You made my day. I will wait for my S7 to arrive. If this PSU + S7 works, I will add more hardware in future.

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

That psu has six 30 amp rails.
You will need to be very lucky to get it to work.


If you do two cables to one rail five times you will be using 5/6 of the rails at a max of thirty amps each rail.

You will over load a rail if you put three cables on it.
So to load that psu correctly you will need to research how a rail feeds to the pcie jacks.

Good luck as it can be done correctly

[ATCkit]

All,

I need a suggestion. I order BITMAIN AntMiner APW3-12-1600 PSU Series with ANTMINER S7 BATCH 3 recently. Order hasn't shipped yet.

I am double minded about PSU; will that work in America?
https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

Voltage Range
176-264V AC
 
Starting Voltage
200-205V AC

Would some help me please..

Yes, it works in America.  However, you need access to 208 to 240 Volts instead of 120 Volts.  This would be a 2 poll breaker in the Main Service Panel and a minimum of 20 amps with 12 AWG wiring.  If 2 poll 30 amp breaker, you need 10 AWG wiring.  I don't think you are going higher than 30 Amps if you are installing a 240 volt outlet for the BMT 1600 watt PSU if you are in your home.  I would suspect if you were in a data center, you would not have asked this question.

240 Volts is the way to go.  You can run twice as many rigs than you can with 120 Volts.  If you don't know what you're doing with electricity, get some help locally.

Could easily get away with a 2 pole 15A 240V breaker and 14GA wire if all he wants to power is 1 or 2 bitmain PSUs. If more, 30A and PDU.

I agree.  We just don't know if he's comfortable taking out a single pole 15 amp and replacing it with a 2 pole 15 amp.  He might need to use a tandem breaker to make room in main service panel.  He would have to make sure no other NON-240 Volt devices are plugged into the circuit to prevent potential fire.  It would be best to have a dedicated circuit made just for the rig with its PSU.  It's quite common for circuits to be looped (in a string) for receptacles (outlets), switches and lighting.  I would be concerned about other devices connected to this circuit that would not handle the pressure of 240 Volts if someone were to accidentally plug a device not made for 240V at another outlet on the same loop as the circuit he upgraded to 240V.

It's best IMHO to make (create) dedicated 240V circuits just for the mining rig(s) and PSU's to avoid possible fire from circuits plugged into looped outlets on the same circuit that were designed for 120 Volts.

I've never tried plugging in a lamp [designed for 120V] in an outlet that was upgraded to 240 Volts.  I have no idea what would occur.  It may be you have experience with this and had no issues.  I can't elaborate on that cause I really don't have experience.  However, I'm usually one to go by the specifications laid out by the manufacturer of the appliance or light lamp.  If the specifications state 120V @ 60 Hz with no mention of 240 Volts, I keep it only in 120 Volts.  That's just me.  Maybe I should check it out some time to see what would happen.  However, I think I would run a line outside to the driveway to see what would occur as a precaution.

When I set up my 240 volt dedicated line, I plugged a 120 volt fan into it just to check if power was there. Well, the fan worked.... on super speed. If I had a hair piece, I would have lost it. Needless to say, I unplugged it quickly.
