02-02-16 Update
The Good News:
I received a reply from Bitmain customer service!
The "Whatever" News:
I was told to be patient, they are on vacation.
There are spare miners in the US, but they are for their "large" accounts in case they need one until the factory returns from vacation.
Be patient, until they return on the 15th.

If anyone else has found a way to receive warranty service before then, please let me know.
I am buying Avalons.


Transaction fees go to the pools and the pools decide to pay them to the miners. Anything else, including off-chain solutions are stealing and not the way Bitcoin was intended to function.
Make the block size set by the pool. Pool = miners and they get the choice.

Just FYI: Antminer S7 working at superhigh temperatures 80C+

(automatic shutdown works at 85C not 80C!)

I have 10 S7 B8 from early december - KNOCK ON WOOD.  No problems.

Stock firmware - actually using recycled cointerra power supplies.  1 to each pair of boards (6 pci each and 1 for controller)  My design and so far so good!

I am the first to flame a company when deserved.  But I think a lot of people don't understand that overclocking is not free and you can't keep the miners running well without controlled temperatures..


Boomin

p.s. but I did have my fair share plus of ant S4 problems.

(automatic shutdown works at 85C not 80C!)


good to see, mine commonly pushes into the 70-74C range during the daytime on a warm day (10C outdoor intake) and drops to about 55-60C during extremely cold nights (-5C outdoor intake and has had no problems. fan speeds set 15-18% depending on weekly temperature forecast to keep it ideally around 65C average


24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

one of my S7 B8 has been restarting frequently - first time I have seen this happening - the rest of the B8's are ok - running full speed at 700mhz/4.6th-4.9th with latest Dec FW

I underclock it to 650mhz but it still ever so often starts rebooting again...

Changed Mhz to 600 but after rebooting it came back at 650mhz -- is this normal?

Anyone experienced this symptoms before?

If I provided you good and useful info or just a smile to your day, consider sending me merit points to further validate this Bitcointalk account ~ useful for future account recovery...

Board 1 just died in my batch 9

Had to unplug it as it would just cause it not to mine.


Who do I contact for warranty repair?

Please dont run your antminer at over 80c, I am scared for your house Smiley   Just because you can, doesnt mean you should lol.  although i'm sure you are just doing it for test purposes.  I'm too scared to even over clock mine at this point, I feel as soon as I touch another setting the miner will suicide itself.

i managed to get some kernel info -- can anyone help me see whats wrong with this s7?
Now.. the s7 cant wake up from the dead... i have to wait an hour or two  before it goes OK for about 15mins then freezes again requiring powershutdown

What would they lose buy having someone answer the phone and sell parts at list price?
I don't know, and I don't know what happened to the US repair place and why its not being used as much. Seemed a good idea but I guess they didn't like the cost.


S5 (Was the opposite of the S3 mmini tank, the plastic sides warped, hash boards fried, but many people made a lot of money early.
The S5 was manufactured on a scale we'd never before seen in Bitcoin land, so the 'high' fail rate mainly just more units existing. And I mean a lot more.


I learned with the S7 if you have a fan failure you are responsible for sourcing and replacing the fan.
The fans are a shame. I repeatedly asked them to reconsider a model as there were many reports of the same premature failure method - the bearing failing and making the fan assembly literally fall off. I reported it on the S4, but it was used again in S5, S7 etc.


I don't believe Spondoolies lost money overall
Money before + money in = money out + money after. We all know they don't have much money after so either they didn't sell enough or their costs were too high (more likely).


I think a company could step in and start selling a $599.00 S7 equivalent today for two weeks and stop for a week and only sell them for 999.00 or some similar marketing game which would still make them obscene profits but if they offered average customer service and RMA process as
No one would buy a miner at a 70% price premium in the hoep of better support. As we've seen with re-sellers, customers are price and delivery sensitive rather than support sensitive, as re-sellers inherently increase the warranty risk.


Don't even talk about a startup full of excited entrepreneurs who would always be on top of things.
I have worked with far too many pre-startup mining companies, unfortunately enthusiasm doesn't pay the bills.


There must be a whole different side to Bitmain service and response that I have not been able to experience.
I don't know, its a hard job dealing with markets across the entire world on a budget. I have to say though, the volume of support requests wasn't that unreasonable for the amount of orders going out so at least a size-able majority would never require contact again.


I understand vacation, I've already said my thing there, too many ways to handle people on vacation, everyone who makes something people want on a weekend eventually figures out a way to give it to them.
Chinese vacations are very, very different to anything we can imagine over here. People don't just 'take' holiday over these periods, the entire COUNTRY goes on holiday simultaneously. I guess the only comparison would be from Christmas to New Years but there were no gaps in between and no one did anything. This includes couriers and distribution on top of staff.

I'm going to guess that a lot of the failures are novice miners without temperature controlled environment.  Or power supplies that aren't up to snuff.  I blew up some S4's trying to overclock and get that .1% but my time repairing and downtime of shipping etc made it FAR from worth it.  I just wish we could turn down Difficulty LOL - that's my real current problem.  Really Fu**ing up my ROI forecasts!

Carry on.
