Since the halving these things are not earning very much at all. I have 2 of them, one of them I got at under 3 BTC with a couple weeks to mine before the halving, and it still looks like it is going to be a long, long time before these ROI and that's without any electricity costs. I have one underclocked and the other setup to underclock for 6 hours a day and then do stock clock for the other 18 hours. Based on what others have said about failure rates this looks like a bigger gamble than I had anticipated.
And what really sucks is that it comes on the heels of S7's that still haven't hit ROI with free electricity and decent resale price on two of them. In about 2 months I should hit an overall break-even on the S7's since I still have an early batch unit mining at an average 5.02 Th/s but if not for the resale prices those things would have been a loss for sure. Wondering if the S9's might be better sold at this point rather than gamble on them lasting long enough to get my BTC back.

I am hoping that the fact Bitmain have gone quiet with releasing batches of the S9. That they have taken it back to the drawing board to find out why they are so unreliable.
Its a nice thought anyway
Its a nice thought anyway
no they are simply replacing the S7's in their farm with S9's and sending bulk orders to other china farms
ref: https://bitcointalksearch.org/topic/m.15721138
which is a 5MW farm being built in Labrador. Power there is $0.025 per kWh
They mention when full will hold "Thousands of s9's"

Judging by the increased hash rate, I think you are right.

Anyone have any idea on how to get a S7 or earlier control to work on a S9? Ive been waiting too long and would like to get this machine running. You just cant update the firmware like the others when I replaced a S7 board from an older machine
August 08, 2016, 06:51:53 PM
Slightly off topic ... sorry
I know some of you guys are running them with your S7's and S9's.....
I'm looking for the pinout diagram for the IBM 2880W / 2980W power supply. I'm not looking for a breakout board, I'm looking to solder pigtails and eliminate the friction contact losses/heat of a breakout board. Plus save $ by not buying breakout boards.
Thanks

Here is the answer:
https://bitcointalksearch.org/topic/help-starting-an-ibm-2900w-psu-1007440
But you simply don't have enough space to solder all wires to the PSU, you would need to build your own fanout connector. And I would def make sure to use all 6+ and 6- connectors so you don't melt down the PSU's connections!

According to our warranty policy, the warranty is void if the product is beyond repair.
Am I reading that right?
If you send a faulty item back and they confirm it doesn't work, then it doesn't come under warranty?
Wut
August 08, 2016, 11:43:39 AM
Does anyone know when Bitmain will be releasing new batches of the S9? It has been about a month since they ran out. Does anyone know what is going on?
Thanks!
Thanks!
I think he should be here soon with the new model.
snip ........
S9 is dead for me.
snip ........
At first, only xxxxxxxx After restart board completely disappeared. This is not normal.
snip ........
From 21 miners are three with broken boards. This is too much.
snip ........
If Bitmain does not change its warranty policy, then I will not buy more S9.....
Seems like a very good summary..and confirms what I suspected - ie: based on what I've been reading. Phillipma seems to have the right idea about under clocking them during the summer. If they were reliable at the default frequency, S9 owners shouldn't need to do that.
Indeed, it seems that Bitmain needs something more efficient and reliable to compete with what Avalon (and a German company which someone mentioned) may bring to market soon. So I tend to agree that Bitmain knows this.....has gone back to the drawing board and will come out with a better version of the S9 or a new model in the next quarter.

Why it took 45 days for repair and shipping one board?
Finally, they never sent me back my board. I got back board with another serial number, and other design.
"Shipping way:
UPS,DHL,FEDEX,EMS, TNT, USPS, or your local post office are available.please note that EMS and USPS provide poor service in HK,we cant ensure they can delivery the parcels in time.
NOTE:
1. Be sure mark "deliveries are made on working days only" and "Antminer" on the items description of
the waybill.Otherwise we wont accept any delay due to missing of these info .
2. It's necessary to package the hashboard very carefully. We can not repair if the PIN on hashboard is lost because of the shipping problem. Please claim to your logistics agent if the PIN is lost on the way.
3. The HongKong warehouse only responsible for receiving the parcels ,we wont accept "Freight Collect",please pay
the shipping cost in your side. Please mark the warehouse NO. 3811
Consignee: (The package will be rejected if there is no "No.3811"; The PSU can not be packed with other stuff in the same tracking number because of customs clearance)
Name:FUKWOK KWONG-No.3811
Company Name:TUNG-D INTERNATIONAL DEVELOPMENT LIMITED Warehouse No.3811
Address:Unit 104, 1/F, Sunbeam Centre, 27 Shing Yip Street, Kwun Tong, Kowloon, Hong Kong
Office Tel:+852-2750 5059 (The number is only available for logistics not for service )
Warehouse:Tel: +852-2750 5150(The number is only available for logistics not for service )"
That looks to open a lot of loopholes for them to claim 'lost in transit'....
PIN?? as in the barcode sticker on the boards??? What would a logistics company have to do with that?
Now as to getting back a different board:
Well, ja. That is how most often any electronics servicing goes. Rarely is any board repaired and sent back. Even using low-cost labor it is usually just not worth the time to do more than verify a board is dead. So, either a re-worked board (from production problems or returned boards from other customers that were able to be fixed) is returned to the customer or if really lucky -- a brand new one is sent.
Of course given that test/replace (not repair) is the norm, the question still remains why it took so long for Bitmain to get a replacement out to them?

S9 is dead for me.
Last week stopped working 2 x S9 miners center boards. One from 650 model and one from 550 model. It was in the most cool place. The chips temperature was never above 95 degrees Celsius. At first, only xxxxxxxx After restart board completely disappeared. This is not normal.
From 21 miners are three with broken boards. This is too much.
I paid a total for sending 3x S9 boards to warranty about 210 euro.
Batch 1 miner's warranty will be over soon . What happens next ? How much does a repair charge after warranty ?
If Bitmain does not change its warranty policy, then I will not buy more S9.
Why do I have to pay for sending the miner parts, when it arrived with D.O.A. board ?
Why it took 45 days for repair and shipping one board?
Finally, they never sent me back my board. I got back board with another serial number, and other design.
So far I have been okay. I think current is a big issue so down clock of freq may be the way to go.

Now I want to know what has bitmain given you for you beeing so arrugant?? be honnest??
Since it appears that this idiot is of the opinion that anyone not jumping on his honey truck to join them in the crap slinging has been paid off or whatever, now Ignored here.
What a yutz...

It actually is kinda annoying to read the same [mostly incoherent and thoroughly profane] conversation in two different threads. You'll have a lot more people paying attention to your message if you're less of a mudslinging jerkass, especially to veterans.
Well put. Personally, I find it hard to take someone seriously when they only have 7 posts and a name like random699. There are too many trolls and folks with hidden agendas out their with low post counts and arbitrary names to take this particular person any more seriously than the next such person especially when the user's post history has a very specific theme.

What the hell do you posting the same text in two different thread ?
First first read about posting rules.

Don't worry bro Bitmain will till give you your F...commission you lousy currupted begger, if you want there some other ppls interested in your services and I guess you would be pleased to Lick some more A... now won't you??? If you had some good sens into you you would help ppls that have been fucked instead of insulting me for saying the Truth if they and you should learn that Aliexpress is Chinese Website but selling abroad for 99% of their business as well as Alibaba now you would say "is not Chinese " pff
For China you have Taobao that's real website for Chinese local market.Now I want to know what has bitmain given you for you beeing so arrugant?? be honnest??

Hi.
I bought 2 of Bitmain's Antminer S9's - the 2nd batch. 12.93 GH/s
I plugged both of them in at the same time - in the same room.
They both started up and seemed to be running ok for a few hours.
The temperatures were around 65 degrees C.
Then I noticed that on one of the S9's, one of the hashingboards was reading 0 GH/s
So i restarted it - and then the board was no longer listed on the Status Page.
This was day 1 - within a few hours of being plugged in.
Now bear in mind that I have also had 5, Antminer S7's also running in the same room + the other S9 - ALL WORKING PERFECTLY.
No heat problem, no electrical problem.
Ok, so I tell Bitmain what happened and they tell me to send back the hashing board - then I get this response:
EXCUSE ME?
So I just paid $1800 USD for a broken machine and you tell me that "because it's repairable" that is somehow my fault?!
Are you F**king kidding me?
Then they refer me to the warranty:
"3. In some cases, the warranty will be void, but Bitmain can still do repairs at your own expense if requested. The following events will void the warranty:
a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;
b. Damage caused by poor power supply, lightning or voltage surges;
c. Burnt parts on hash boards or chips;
d. Miner/boards/components damage due to water immersion or corrosion due to wet environment."
Ok, let's see..
(a) does not apply - they told me to remove the hashing board and send it to them'
(b) does not apply - I have 5 other Antminers all running on the same power supply - same room - same temperatures. THEY ALL WORK.
(c) I didn't see any sign of burining on the board - if there is I assume it's because there is something wrong with it.
(d) does not apply
So basically they are trying to screw me.
I am probably going to have to sure them, luckily I have a very good lawyer in Hong Kong. So I will let you know what happens.
But anyway - I personally WILL NEVER BUY ANYTHING from these con artists ever again and I seriously WARN anyone against giving these people any of your money - as they are not willing to replace faulty goods.
My Antminer S9 was faulty within a few hours of starting up.
How any serious business can pretend that that doesn't fall under warranty is beyond my comprehension - only a total asshole thieving lying scumbag would refuse a repair in such a situation.
So BITMAIN you can go and F**K YOURSELF. GOODBYE.

Did they give you a price on a new hash board?
August 07, 2016, 01:07:15 PM
I think its over with mining gear from Bitmain, until we see either Avalon specs and pricing. So nothing new until mid September.
