Topic: 28nm ** 1T ** 900W【JingTian miner】 in production !!! - page 8. (Read 26317 times)

Im looking forward to the OC guide- Do you think a EVGA 1300W g2 is enough to overclock, or should we get something higher?

I will let someone put more pictures here.

I need to pick up my system now. LOL. I will try to do a good over clock then report to your guys.

The one you see here is original and others are copycats.

There are major differences:

1. Our system as CK already saw it, is made with high quality part. So you can overclock using ours, but DON'T try that with copycats.
Unless you don't mind to turn your system into a toast.

2. Our system you can go around 1.2T.

3. You know we are designed for rigs.

4. The MCU enabled with communication boards are original created by us. And copycats are all following up.

Copycat system a little bit cheaper because they don't spend on research but also they don't use high quality parts.

Alright, thanks for making that official 
How about the pictures from the demonstration you held, will they be uploaded soon?

Yes. Those are from my company.

As low as 4200 USD right now to be correct. 
And hey, the Bitmine situation is truly fucked up.. sorry for your loss.

Yes,... and pricing from $5000 to $8000

Generally funny, I have ordered miners from Bitmine, already two months late. Now i can get faster from Chinese manufacturers than directly from Bitminy. Crazy.

There´s more like 4+ different companies selling these 1TH miners. They´re all using the same blade design, A1 chips, raspberries, etc... the only difference between them is the casing and the color of the cables (From what have been revealed so far).

It is confusing, but I think at least three different Chinese companies are currently offering similar 1TH products that all seem to be using the Bitmine A1 chips.

I agree. Both Bitmine and Bitmine and Innosilicon worked together to develop the chips, and no-one has posted any proof as to exactly what legal rights Innosilicon has to resell the chips, but it's certainly plausible that they do have some resale agreement based on the contract between the two companies. Innosilicon could have paid for part of the development in order to be able to retain some ownership of the IP.

It sounds like QuestionTime is simply spreading FUD to try to show down a potential competitor to Bitmine. Either post proof to back up your claims of IP theft or STFU.

I´m a little bit confused.... how many representatives for the JingTian miner is on bitcointalk?

(Seeksilence, skyfromwell and JT miner)

It is as simple as that.

Bitmine and Innosilicon worked together to produce the chips, so both of them have rights to produce/resell the chips.

But even as Bitmine had an early start on availability of chips and great cheap costs, they FAILED to deliver their system successfuly and on time.

So AFTER my systems of 60T RUNNING over 1 month, and start to sell to public, Bitmine's system still NOT seeying anywhere.

From pespective of marketing strategy, this accusation is just a tactic to slow down our sales.

Technobit does not produce desks or rigs, they produce blades and that is different since it'a semi assembled product, not finished product, therefore no distribution omission, however they are credible.

Bitmine have already made themselves quite clear on the issue and until they've made a statement retracting the previous statement it's much more likely the the statement was deleted/moderated rather than retracted.


Authorised distributors of bitmine tech: http://bitmine.ch/?page_id=5204 - unless the chips were sourced from one of these guys or bitmine themselves it's corporate theft.

Furthermore, we have yet to hear anything from Innosilicon to suggest that they have obtained the rights from bitmine to produce these chips for sale.

Thanks for reasonable people's support and also thanks QuestionTime for a debate to make things clear. BTW, QuestionTime made a big mistake to challenge us instead of other agent to sell copycatted miner since JTminer is the original .

A lot of information come out, let's do a summary:
1. dimension: 426*380*200, smaller size than other miners.
2. Can do overclock.
   i. extra power supply can give you the ability to over clock. The boards are equipped with 32+A current capacity power supply per chip:), in 25G/s mode, it only consume 20A per chip. so it has room to do the over clock.
   ii. Linear Tech power supply + careful design gives the ripple only at 20mv:), it will stabilize chips using the higher clock without too much HW error
  
   Kind reminder: For those who bought a copycatted miner from other reseller, please be very cautious to do overclock, it will burn the chip and board.
3.  JT miner spend lot's of effort in the firmware and Pi side. they use the ST MCU. the firmware is written from 0. after JTminer use the ST MCU. some vendors' solution seems to have interests in ST MCU too:)
4. The Pi board can drive up to 8 boards (in lab we do), and each MCU to control the two SPI high speed chain. in this way, give the whole system more flexibility and scalability.
5. We do not have authorized distributor now. Only a few sample units are being sent out.
6. The order for 1200T is to be completed soon. We also have chips in stock for future business.

Chip related question:
Still wait for an answer from giorgiomassa for the question (seems we will wait for a long time ):
Does Innosilicon have right to sell the chips or not?  

Why the message from giorgiomassa on March 04 QuestionTime keep quoting was removed?

You keep quoting a 'retracted' statement and the owner of that statement is yet to reply to a few people to explain fully if his statement is legit, if it was deleted/moderated, he can come and let everyone know what happened and expose it all for everyone to see, it's really easy to do, but still nothing...

Take a walz over to the bitmine thread and you'll notice what a complete mess they are in, scam accusations, locked thread and all and it seems as though Giorgio is quite comfortable with deleting statements, even on their website. By what is going on there I don't believe anything that has been said so far and I doubt they secured anything in the rush to amass money... it's starting to look more and more like a BFL every day.

zefir is on that page and from their posts it seems Technobit and others got their chips from zefir or directly from bitmine - perfectly legit.

I want one of these but don't have enough BTC left, spent it all on Ants!
