If u buy miner instead of BTC then your speculation is riskier AND profit is LOWER Thats why there is no point in buying miner that will not mine more BTC then it costs
Example:
1BTC=300USD
1.im buying s7 for 5BTC = 5BTC or 1500 usd spend
2. im buying 5BTC

few months later i got like 3BTC back from s7 and 1BTC=1000USD
1. i have 3BTC or 3000USD - electricity = wow profit 200% in USD hohoho great BUT:
2. i have 5BTC or 5000USD = 2000USD more than example 1.. profit more than 300%

If 1BTC gonna cost 200USD then:
1. i have 3BTC = 600USD -- you lost 2BTC and 900USD
2. u have 5BTC = 1000 USD - you lost 500USD so u have 400USD more anyway

Its Always WIN for buying BTC unless ofc u think your miner gonna mine more BTC then it costs.
There is one exception becouse you can sell your miner but if ppl would think then noone would want to buy it from you. And ofc your miner can burn or something. So more RISK and LESS profit.

P.S
And i want to add one more thing that if we all just buy BTC then we will help BTC price will go highter. If we are buying gear then yes we are buying BTC but then producent will sell this BTC soon for USD so we r not really helping BTC price to rise

I see it differently.
I have at the moment 31 x S7 + some water cooled S5 for  heating .  150TH/s  mining at this month daily 1.10 BTC  (Antpool PPS )

I have 3x 50A  220V   It is always full. Some of the miners have been at a friend's house - today 4 x S7 Max 12 euro day , in a month less as 400 euro.
My home electricity consumption is not more than 3500 euro in a month.
So total 4000 euro or less for electricity.

If the BTC  price is 300 euro , then if I can sell all mined BTC and  I got 9900 euro or more per month.

In this case, I have recouped the purchase of three S7  miners per month-  2000 euro (or less) per miner with shipping and 20% VAT

But I sold last my BTC, when 1BTC=350 .

With mining you can earn more than with the purchase of BTC and holding them.

But you must sell when the price is high .. And you must have a reserve to pay for the electricity when the BTC  price is low for several months.

If u gonna mine more BTC then you had to paid for 31xs7 then its ok.
And instead of paying for electricity when price is low you could just buy more BTC
Do your own math:
1. BTC you had  to paid (If you paid USD then BTC you could buy instead of miner) for that 31 S7 with shiping&tax. There is no need to count psu etc. + How much BTC you could buy instead of paying for electricity x any BTC price you want. Versus
2. How much BTC you will mine x same price as in 1.

If 2 = more euro then you did right choice (for making more money)
i know many ppl dont care and have enough money and just want to mine becouse its addictive (i was miner too)

But at the end just for money making calculations:  if your mined BTC - electricity + BTC for your miner after you sold it = more BTC than you paid for the miner = WIN. If its less then it was better to just buy BTC and hold.

Its diferent if ppl using miners for heating like few posts above. Its almost always WIN ;p

My Internet went down before i woke up this AM.

My S5s came back online when the internet came back up...but my S7 (batch 1) didn't. I can still see it when i check it thru my LAN. All the ASICs are there and have all 0's but there is no hashing. The fans are running too.

I rebooted. No change. I switched PSUs - still no change. I did a few reboots- no change. Then i reset it to factory settings- still no change. Finally, i called Bitmain in Denver. The tech guy used chrome remote desktop to look at my kernel log , miner status etc. Then he shh'd into my rig. He couldn't find a problem either.

So I will be contacting Bitmain to see what can be done.

Has anyone else had this problem?

I have this issue, go into Network>Diagnostic and then ping something. Go back after a minute and check if it is hashing.

Tried that already. The ping was successful but still no hashing.

Someone analyzed my kernel log today and replied with this:

"this looks like memory problem with your beagle bone black
change it with another BBB or find S5 BBB and reflash it for S7"

Bitmain said"

"i would suggest you to obtain micro SD card. and to mount s7 firmware from https://www.bitmaintech.com/support.htm?pid=00720151023101739550pOBiK5sO06A0

on sd card.

and then to place it in unit. maybe then unit will start working."

I will try that and let you guys know if it worked. I'm guessing more people will have this problem. If this fixes i, that would be nice.

I'd be very interested if this works for future units.  I have already sent the 9 hashcards and 3 controllers back to Bitmain.

It didn't work.

Now, I think the controller is bricked. All the LEDs on the front are now off. The blue and green lights inside the controller are solid ( ie: not blinking). I can't see it in my browser anymore. I can't reset it to default with the reset button.

So after 7 weeks and a few days of perfect functionality, my S7 is not working after an overnight internet outage of about 3 hrs.
 ( Note: there was an internet outage of about 30 mins a month ago. It didn't affect my S7 then. So, it seems if there's a longer internet outage, it messes up the controller or its memory.)

Bitmain Warranty has not responded to my ticket (#1384) since i reported that using the SD card did not work and the control board seems to be bricked. I also asked them if i could have approval to do an RMA and no response to that either.

Should I blindly send the controller ( with my invoice etc.) to Bitmain Warranty in Denver and hope they do something for me?

or

Do i have to wait for them to respond with some kind of RMA approval number like you you get from other companies (ex: Corsair, EVGA etc.)?

I would give them a call before you do anything...1-844-248-6246

got my batch 5 today, all setup & running well... just wanna share & i think most would've noticed the slots on the sides of the miners.

slotted 2 x batch 5 with my batch 3, just like a lego block. makes it more sturdy. like the housing.

all of them hash as advertised, stock. all pcie's connected from 4000W psu. not gonna touch anything till the 90 days warranty passes.

temps are at mid 50's. very low HW error. 0.0001%

the hashrate does jump around quite a bit but avg's out to the advertised hashrate.

1 of the batch 5 has a woong woong woong fan sound if fan is above 60% .. tried to loosen & tighten front n back fans, no fix.

another batch 5 controller has no green LED light but it works fine so i'm not gonna make a fuss or touch anything. the LED next to the red LED near to LAN port.

other than that, pretty happy. no warm cables (16 AWG custom made) or so.

can't wait to see more ideas when the 90days warranty passes. i'm sure lots of guys here are trying something & doing innovative stuff yeah ?

FW is stock sep 15. i think i saw some guys updated the OCT FW. any difference ?

waiting on the data cable to save a controller board. hooking up 2 in 1 when cables arrive.

regarding ROI .. yes it's tough & NOT impossible at this stage but later, yes but depending on individuals .... i;m gonna mine the the chips, board, etc melts away so i think i'm gonna hit ROI & prolly a lil' profit.

buy BTC or miner almost the same imo, we all want BTC go up !

Was the Oct Firmware released to resolve the issue when there was a loss of the internet; the unit would not overheat/brick?

[Cyper_BLC]

about the Antminer S7   
i would like to know if there is an option via software to silence the buzzer ?
if not is there a way to access the buzzer and silence it via hardware ?
please also tell me what situations make it buzz.

you can do that

You make one mistake. My electricity cost covers the sale of BTC. I only sell it when the price is high. Thus, it is like a loan which I will pay always return, selling BTC.
I can not use it for the purchase of BTC. if the price is low , because I have to pay for electricity..

Over the last three months I have sold used miners more than 100 BTC
The WIN should be only after the sale of the all S7 miners.

It depends on the market,  how great it is to be.

[generalt]

You can not send back the entire miner. Bitmain warranty does not work that way.

2. All sales are final. No refunds will be given. Defective machines can be repaired for free under the Bitmain warranty policy. After the warranty period, machines can be repaired for the cost of parts and labor
4. Customer must return the defective parts at own expense after opening a support ticket and troubleshooting with Bitmain's instructions.

I was lucky with my 3x S7 repaired blades but unlucky with 2 xS5+ blades which is last sent back from china.

After a few hours

Wow it looks like the whole chip came off with the heat sink.  Is that what happened?  If that's the case, then at least they used some strong thermal glue there!  Sorry to hear about the bad luck though.

ANTMINER S7 BATCH 7 - Sold Out - are FOR SALE!!!!  

[bosimao]

ANTMINER S7 is available at bitmaintech.com
with BM1385 chips, 4.86TH/S, 0.25J/GH
only available at bitmaintech.com

Sales will be open at 9pm(UTC+8), August 30th, 2015

 
                                  
Bitmain is pleased to introduce our latest machine, the Antminer S7. This powerful machine features a small form factor, like our previous Antminer S5, while utilizing the denser hash board arrangement of the more recent S5+. This is the first Bitmain product to use our recently announced BM1385 chip, which is not only more than twice as power efficient as the BM1384 chip before it, but is also the most power efficient chip available to consumers today.
https://i.imgur.com/R8DH9nt.jpghttps://i.imgur.com/YrG7Jx5.jpg

The Antminer S7 has a more dense configuration than previous Antminer machines, using 162 chips in the same space that the S5 used only 60 in. The S7 uses just 1,210 watts of electricity to deliver a whopping 4.86 terahashes per second of pure mining power.

S7 Specifications:

• Hash Rate: 4.86 TH/s ±5%
• Power Consumption: 1210 W (at the wall, with AC/DC APW3, 93% efficiency, 25C ambient temp)
• Power Efficiency: 0.25 J/GH (at the wall, with AC/DC APW3, 93% efficiency, 25°C ambient temp)
• Rated Voltage: 12V+5%, should not be less than 12.0V
• Chip quantity per unit: 162x BM1385
• Dimensions: 301mm(L)*123mm(W)*155mm(H)
• Cooling: 2x 12038 fan
• Operating Temperature: 0 °C to 40 °C
• Network Connection: Ethernet

Notes:
1.   Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter.
2.   PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 are required.Do not connect more than one PSU to the same hashing board!
3. Separate power supply to control board: there is one additional 6pin PCI-e connector on the IO board which must be connected to the PSU to get power. If you use different PSU for hash boards and control board, please make sure to power the hash boards first and the control board only after the hash boards have been powered.

This machine is not only our most efficient ever, using less than half the energy per gigahash of the S5, but it is also our most powerful miner to enter mass production (the S5+ had a higher hashrate but was sold on a limited basis). At 0.25 joules per gigahash, this is the most efficient machine available to the bitcoin mining public.

Wow Tupsu.... 31 x S7s, my goal is is also to get that 1 BTC per day scenario...
I am still a newbie and I have only 3 x S7s now, and would be accumulating BTC & $$$ to buy more S7
Sorry if I am asking to many questions...
Could you share how to do you house/rack/ your S7s ? I am considering a vertical setup for my S7s to push out heat and reduce the noise
How do you manage the electricity bill... 4k euros a month.. gulp!
How do you design your electrical distribution to the S7s? Is 50amp per 10 x S7s sufficient?
Do you keep some BTC to the vault and spend the rest to buy more S7s and pay the power company?
Are you considering solar energy to offset the power consumption?

eBay about $30 shipped, search for IBM Bladecenter 2000 PSU. You need to buy the board separately though.

Thx Guys. i got it sorted. The controller is on it's way to Denver. With some luck i could have it back by mid next week. I just hope i don't have the same experience hawkfish007 reported when he got his back. Man that really sucks for him.
