Topic: Official BITMINE CoinCraft series 28nm ASIC miners thread - page 61. (Read 565240 times)

With ~ 1850 BTC in their wallet ( https://blockchain.info/address/1Cz1pTK8GxsJqdHQrFLWh77WwYsyqyDX3k ) which is currently about ~ 842,900 USD it should not be too hard to start fulfilling refunds, is it?

Check www.bitminerefund.com and you will understand why people chase their money, every day more and more refunds are added on that website. In less then two weeks already more then $ 200,000 in refunds are added.

Christian explained:
we had a tremendous amount of problems, starting from the chip manufacturer till to fake chinese components,
problem during production, problem during SMD, problem during shipping, chip failure rate (40% in the last batch), mtgox failure with a lot of our bitcoins,

what you think ? we are happy to do business in this way ? this dream become a nightmare for everyone of us.
we started this adventure because we was sure to be better than BFL and all the other competitors, but the fact is that doing these miners is not easy.

and now we are flooded by refund request and we are selling all our assets for give back the money to our customers, seems be difficoult for the waiting customers to understand we had paid upfront our suppliers too.
we are working 14h day, 7 day at week for finish all the outstanding.

Start being a man not a chicken from today on.

The production started weeks ago. The assembly didnt started yet, today tuesday, and is planed for friday.

Can anyone help me here?
why I  just show three modules in Webinterface :
Modules:


Module 1 => 211.26 Gh/s
Module 2 => 188.41 Gh/s
Module 3 => 183.42 Gh/s

but I have actually 5 physical modules....

thanks everyone, please help me?

In less then two weeks the site has been online, I guess there is way more to come.

Oh...I just fix it , just turn it into turbo light model. but how can I power it off???anyone knows?? thanks

and another simple question? how to power it off ,just power off the PSU directly??

Hi, everyone ,I come here again... I finally got my machine, 1T+600G, when I open it ,the PSU for 1T machine is 1000W, I guess no turbo will be supported at all..because power is not enough...BITMINE should sent me 1300 or 1500W right?  it's a shame... what's more...the netcard is moved..and I pluged it by myself...

here comes a big problem,,my 600ghs machine just run 400+gh,one of the moduls is 0 Gh/s . can anyone be nice tell me what's going on here??how can I fix it???
thanks  ...

Holy Cow,

a amount of already $ 228,405 in refunds not paid!

To get a bit of an idea how many refunds are due and how their "queue" might look like: www.bitminerefund.com

excellent.
only have also some Ants S1's so room is slowly getting getting hotter and hotter.
But without Ants the temp will drop to 42/35

For aluminium isolated heatpipes (165mm):
http://www.ventilatieshop.com/c-1653243/aluminium-flexibele-slang/

BITMINE Non payment of refund.

I put my refund request in at the beginning of April, I received a reply the same day acknowledging my refund request, and I was also told the the refund would be paid within 30 days

I have emailed BITMINE 4 times asking about the refund, the only reply I get back is is the automated acknowledgement.

@giorgiomassa, If like you say on your website you are having problems paying all of the refunds in time and that you have created a refund queue, then great. How many are in that queue, how many refunds are you paying a day. When people request information about non-paid refunds tell them where they are in this refund queue.  Of course if the refund queue doesn't exist, then you won't be able to answer these questions, which is probably why BITMINE are not replying to my or other people emails.

I would like people to know that I am another person that waited 77 days before requesting a refund, and has now been waiting for another 48 days for a refund.

If you are thinking of doing business with or buying from BITMINE, PLEASE BE CAREFUL as you cannot trust anything they say, whether it is promises about hardware or promised refunds.

Yeah if you use the 220V outlet and not the 110V outlet it will draw less amps therefore run more efficiently.

ty for clarifying.
in some of your earlier posts you mentioned you got heating issues in your attic. I am in the same situation. How did the heatpipe thing go?

giorgiomassa,
BITMINE returned the money to my brother.

Refund issued from April 11, 2014 order 321x

A shame that a company with BTC 2000 and again in cash pay to have them where they are.

 dignity and return what is not yours.

 

giorgiomassa,
BITMINE give me back my money! And I'll forget about you forever!

Refund issued from April 11, 2014 

P.S. Forgive me if someone interferes with this message!
But I will write this message on each page until BITMINE not return me my money/Bitcoins!

In conclusion:
I have reached 1,2 TH/s for a very short time before I decided to reduce clockspeed and voltage, because the miner got very hot (65°C). This would be far from 1,25 TH/s with no hardware errors.
Also the accepted shares/HW ratio would be far too high with bitmine log (over 150%), with cg miner about 2%.

So my question here are:
1. What is the real amount of accepted shares?
2. What amount of hardware errors is acceptable? I have read sth about HW/A < 1%, some ppl. on the other hand say no HW errors should occur.
