Topic: 28nm ** 1T ** 900W【JingTian miner】 in production !!! - page 13. (Read 26317 times)

1. The chips out of Foundry at last Dec. 28, and our sample system came out at Jan, 5.

2. Around Jan 23, we started first batch of the sample systems (totally 70) manufacturing  and before Chinese New Year, 60 of them went up online.

3. Our first order is 1300 systems, so we were not daring to do mass production BEFORE the stability test finish. Otherwise if any defect on the PCB boards, then you have to dump a large amount to PCBs (that was what Bitmine did).

4. After things proved to be right and long Chinese New Year holiday was over, we started the big production.

5. During this time, some guys were able to get our original designs ( this is China, LOL), and begun producing their sample units.

6. So since our current production were already paid for, so the next available units will come around March 15/25 time frame.

7. Even thought Bob contacted with me first, but apparently someone tricked him into what he believed the system were from us.

8 .Those systems were sample units made by copycats and NOT from us. Period.

9. Friendly advise: Bob, DO NOT attempt to over clock, you will burn the chips.

10. We will give a production presentation in next Weds. day (Shanghai time), and one thing is for sure, those sample units you received never went longer period of testing. Neither some parts on their board are up to the standards you like to see, so I have to say "Good luck".

11. If you are lucky enough by chance and those parts turn out ok, the max you can go probably around 1T. But the max our system can go is around 1.3T.

Older design, faster available.
What is different in your new design? This would give us a hint what this is about ;-)

That's our old design. The new design is Only in JTminer now and not being cloned.

Yet all 3 boxes I have gotten from 3 different sellers all are the same exact box, down to firmware + pi image and case PSU and blades.

You either have some SERIOUS leaks going on, or are not the originating factory to begin with.

Unfortunately, you are NOT our authorized distributor. The miners you sell are NOT made by us.

Well if anyone wants to check... I have a dump of the rPI image it came with... should be easy to see what CGminer driver it uses right?

If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip. So the question comes: Does the "Coincraft A1" chip means "A1" chip？I don't think so. This is something like Mcdonalds can make their hamburger and KFC can make their own too.

We do NOT buy chips from bitmine and have no business with them.

_"Dragon" miner_





At this stage it seems all the 28nm miners originating from China (JT, JiangTian, Dragon, etc) are based on the bitmine CoinCraft Desk design using CoinCraft A1 chips. It is still unknown as to whether the A1 chips going into these Chinese machines have been legitimately obtained.

Some miners will be added for testing.

Notified him that he got a different brand miner from other seller instead of us.

Warned him about what?

 JTMiner and JiangTian Miner are the same. But Minersource got a different brand miner. We have already notified him about it.

We have notified him the miner he received is not from us:

I am new to the forum. Now I have a little more sense about the forum. I am happy to answer questions but I could not disclose some information even I know the answer. That is my trouble. Also I do not have professional training on marketing. All I do now is to deliver what I know after I make sure the information can be disclosed. So some answers are not straightforward. I apologize.

Thanks for your explanation.

Are these two products sourced from the same design/production company? They look very similar.   JTMiner vs JiangTian Miner?  The name is almost the same too.

From my understanding Minersource is selling the JTMiner.  Bobsag3 has posted pics in you all's threads of his miner being delivered.

Also my comment in regards to post sounding like a riddle or guessing game was not about the grammar itself more so just you bullet the list and the post seem to just be a story not an answer.

I don't think the product is a scam at all but mainly the marketing for a new product is not helping.  As you know bitcoin technology moves fast and the dodging of questions does scare new customers, esp ones who have been on long long waiting list in the past.  That's why people have questions they want answered.

They are NOT selling our products and they are not our authorized distributor. Please show some respect and do your own ad post. Thanks.

Minersource is selling these too.

It is a big effort to explain something you know the truth but could not say a word. Time will prove when everything comes out from the surface.

I only use this account unless my account is hacked. So if you doubt my personality, then stay away from my post. I am not a native English speaker. Maybe sometime I used some inappropriate words I did not realize. If so, I apologize for that.

We are here just providing an option for you. So you know at least there is some possibility that 28nm 1T miner is in mass production. You could doubt it before we earned enough trust. Your money is still in your hand, not in ours. So we do no harm to you. If you think this is a scam, then stay away. The opportunity is for someone else. Our sample units are not for free. We also have some rules for selection. Some real business men will take the risk and grab the opportunity before things come out. I admire their courage and business sense. For small investor, just wait for some reviews from trustful members.

Thanks.

SeekSilence stated they are waiting for reviews from trusted members.  Checking around, reading different posts, and asking questions (as is my nature), I read some not so reassuring feedback.  As far as I am aware, None of these folks have a miner in hand at this time.

Lets see if you have an answer for this: 
Provide some names of the "trusted members" that actually have a miner in hand; and as you  say, are reviewing and testing your miner.

For all anybody knows; you and skyfromwell (and a few other accounts here) could be one and the same person.

Hope still prevails.  However, Beginning to have serious doubts about you being legit.

Buddy, take easy! Drop me a mail and let's discuss in private.
