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

[ATCkit]

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.

Ouch... Bitmain really should change some policies. I ordered several batch 6's at $1625 each. And now batch 7 w/ 5th shipping the same time mine are, arg.

If they were going out a month after or even two weeks i'd understand more. Not much I can do but vent a little.

well I mean...batch 7 is still overpriced.  Funny how its priced in btc though....maybe if btc goes up to 500 and its still 5.05btc you wont feel that bad?

I believe that's the reason it is priced in BTC.  BITMAIN, believes the price of BTC will go up instead of down.  Hence, pricing it in BTC like they did with the S1 when the price of BTC was high.

fr4nkthetank - 500 at 5.05 would make me feel a liiiitle better lol. I do believe time is running thin for cheap btc. Once the halving media drums begin beating it should be a steady rise. Although... margin trading I think is detrimental to organic pricing with manufactured price swings on the books. I guess we'll see how the market behaves to buying pressure vis a vis whale shenanigans.

dmwardjr - Agreed, I think through sales and other metrics they can gauge the interest level and potential for BTCs price in our near future. I'd take the new batch 7 pricing as a monetary strategy based on Bitmain's projected earnings.

I think all conditions are green for a huge pump.  There has been massive accumulation of btc in my opinion (look at low to moderate volume periods, with what seems like a price floor).  The halving in itself means nothing, except for less selling pressure AFTER it happens, but it is a good excuse/reason to pump and entice massive buying once the price skyrockets.  Financial types have been buying too as were reported in many articles on mainstream media, and they are out for one thing - profit.  they dont care about nothing but profit.  So dont sell and hold on tight we are heading for a wild ride.  But dont kid yourself, it will crash down like Iggy Azalea's career.  have fun.  

└(°ᴥ°)┘     nothing to do with btc but how did you draw this?


batch 8 is open!

4.73btc for a 4730 gh machine? uses 1293 watts

There are most likely no real batches-there are two machines with 135 and 162154 chips respectfully, which engineers/marketing sliced and diced into "batches" based on individual machine variability.

"For sure my wife would not let me keep the S7 with that annoying loud howling sound so I had to come up with a solution."

Unless you go watercooled the S7 is not a good idea for home miners, imo. Seriously, what are you guys thinking with your homemade tubes and extensions, they are a serious fire hazard. Let alone the noise pollution.

The extreme heat these monsters are releasing have marked a red line for me. The chance something is burning or melting, as demonstrated with pictures in other threads, is warning sign enough that home mining has reached a limit. And 1200 watt PSUs, do they even last for more than a year 24/7? They are also damn expensive.

Designwise, I don't like the entire single heatsinks on the back of the S7- many have reported them to be falling off. Back in the days of gpu mining you were better off with an AMD 5870 than 5970 too. It was just too much of a hassle to get them cooled and running smoothly. The 5970s often died prematurely, no wonder.

Until something has improved, the S5s are probably as high as I will go until the (final) end of home mining in August 2016.

I'm probably in the same boat. I find it hard to realize people are running these in a home. The noise alone would prohibit to run S7's in an apartment/condo at least in my state (NJ). I'd have my neighbors banging on the door at 10pm. Even after replacing my jet blasters (original S5 fans) with quieter fans I still hear that hummmmmmm throughout my house, regardless of which room I'm in. I do live in ranch style house, which is not a good scenario since internal walls do not have insulation. I did insulate with noise dampening insulation on the cheap. All my S5's are in one room with a single window air conditioner. Even when it is almost 50 degrees out (at night) and 60 degrees (in day) the S5 temps will increase to over 60-62, which I don't like to do. I do admit, if the jet blasters were installed I wouldn't need worry at all. I have to give congrats to the new guys who are running these S7's in their homes. I would imagine some really creative options with trying to suppress the noise. Eventually when temps go down to 40F and below consistently I won't need to bother with the temps at all until the spring, by which time home mining for me will be over. Kind of perfect timing really. I did always want to get some 4-5 inch air duct hose and expel all the heat right out the window, but could never figure out how to build it. Don't want to invest another $1 into that setup, so all choices of changing stuff around is not in the cards.

Good luck.

At almost 1300 watts I think I'm done chasing the mining train. I may have mentioned it before, but most home outlets let you pull about 1200-1300 watts for the entire room (circuit). That means you're asking your ancient home wiring to pull 100% for 24/7 mining. Fires are a real possibility once you get in this range. Imagine all the 17 yr old kids that have a few BTC, order a S7, and plug it into their mom's basement unknowingly overloading the circuit like a Christmas tree with too many lights. Spark, spark, and two huge fans to kick the flame up. Now you're looking at a home burning down and possible lawsuits, though with BM being in China a successful suit is unlikely.

If you are talking about circuits inside U.S. homes, 15 amps x 120 volts = 1,800 watts.  A 1300 watt rig would consume 72.2% of an 1800 watt/15 amp circuit.  That's approximately 3% under the 75% recommendation by the NEC for a 15 amp circuit with 14 AWG wiring.  

If they have other devices (lamp, clock, etc...) plugged into other outlets on the same circuit, there will not be as much heat as you might think at that one outlet the PSU(s) is plugged into when powering one S7.  Most of the heat would be at the breaker in the Main Service Panel (MSP) while the current is distributed to multiple outlets for that circuit.  It is the circuit breaker that would be at fault of any potential fire [For not tripping].  You are mistaken if you think the PSU(s) and rig would catch on fire for pulling only 72% of the available current for that circuit.

Even if the circuit is a "loop" circuit instead of a "branched" circuit [with the rig being the first device in the loop] there could potentially be quite a bit of heat at the outlet the rig is plugged into.  Yes, in that case, there would be a lot of heat at the breaker and the wire leading up to the first outlet in the circuit.  Then less and less heat for each outlet after the first in the loop, providing the rig was plugged in the first outlet in the loop closest to the breaker.  Is this the fault of the rig?  No...  It's the fault of the owner if old defective wire catches fire.  It could potentially be the fault of the manufacturer of the breaker under certain circumstances.

As the customer plugs in and turns on more devices at different outlets on the same circuit, the circuit breaker should trip once 15 or more amps flowed on that circuit.  If it does not trip and a fire is created, it will not be at the outlet where the rigs are located.  It would be in the MSP where the defective breaker is located.  This is assuming the wire gauge in the home is 14 AWG.  If the wiring is old in the home, that's the home owner's fault for running devices on defective wiring.  It's not the manufacturer of the device fault.

It is my opinion that one should proceed with caution when mining with multiple S7's.  In that case [Multiple S7's] one should consider creating a space with circuits dedicated just for the rigs; preferably with a 240 Volt circuit(s) and PDU's or whips.

Do not worry. Europe does not have this problem.

Yap, in Europe electric grid is strong.
My basement can easily hold 5 x S7

I'm curious...

In a typical single family home in Europe with 3 bedrooms and 1 or 2 baths, is there normally 200 amps available in the Main Service Panel?  Also, are the breakers pretty much similar to the U.S.?  Meaning, do you have 15 amp breakers on 14 AWG wiring, 20 amp breakers on 12 AWG wiring, 30 amp breakers on 10 AWG wiring, etc...?

[hodedowe]

The question is not the electric grid, it's the wiring in the house. The grid can handle multi-megawatt power surges without issues. However, most new homes in the US have 14g or 12g wiring with various insulations that melt at different temps. Older homes are much, much worse with cloth insulation or wire you wouldn't put in a lamp today.

Europe likely has the same wiring. As a test, feel your plug and see how warm it is. I'm not saying everyone's house will explode, but you're pushing the limits on a lot of wiring with those wattages. You better know what's behind the wall. For 6500 watts you should be using 6g wire, not 14.

Totally agree.

And yes, you make a good point with the cloth insulation on wiring in much older homes.  That's also why I was mentioning the word "heat" several times.  I'm assuming people would feel the outlet for the heat I mentioned.

Well, after 2 weeks of steady hashing and perfect functionality, my S7 (Batch 3) suddenly stopped hashing and has bricked.
All front-facing LEDs are off now, and the only LED that is on is a steady red light on the main control circuit board on the top of the device.
The fan is on very low, and I cannot connect to the miner via its IP address any longer. The PSU (AW3) works just fine.

The miner was running on factory default settings the whole time, and temperatures were well within range of normal use.

Pushing in the hard reset button for 10 sec. resulted in a beep followed by the front two LEDs (green & orange) staying on and not blinking with the red light still on on the controller. After repowering, the front LEDs remain off.

Any ideas on how to fix this, or what caused it?

[yslyung]

home mining days are going or gone, sad to say it but it;s just the truth.

at my part of the world i get 240V just like uk so a tad better.

still no techies to reply my earlier posts ?

i bet that certain miners can be oc'ed safely, some partially & some can't be oc'ed. i got a feeling that it's related to production hence the different batches with different clocks.

what' the max freq to oc safely ? hmmmmm

i thought over 625mhz is in the danger zone but now voila 700mhz. it's pretty dependent on the input voltages via pcie. make sure it's +12V or more if considering to OC any of the s7's. i still run mine at stock speed.

you got what could be described as SMD (sudden miner death syndrome)-depicted here by AriesIV and others (in his case, bad miner even killed a good controller). I had a spontaneous recovery in such case (after resetting router and bridge), but others did not succeed. Someone also reinstalled the same OP system again and someone was rec by Bitmain to try pinging in Network pane to no avail.

you cannot connect to it after reset? or can connect with no hashing?

Neither works. Reset does not work. Holding reset down makes a beep and then red + green LED on front stay solid. If i tap the green button thing to the left those lights come off. At no time am I able to connect to the device..

maybe start again by switching psu off for 20 min, then try again. Sometimes recovery is possible (if controller overheated from low fan) plus check if you actually have internet connection and ethernet cable is properly engaged (the connector is a little flimsy).
