Topic: [$2,650] 1THs Coincraft A1 28nm ASIC miner shipping from China (Read 9382 times)

Excuse me this image work to A1 gid miner?
http://gawminers.com/products/1-1-th-s-a1-by-gridseed-1-month-of-free-zencloud-hosting-service-24-hour-activation-asic-bitcoin-miner

Zoomhash has this listed as a 220v only unit. Is this correct or can I plug into a 110v outlet?

It seems he has a better market in China.

What ever happened to Qiangminer ? No longer interested in selling units ?

Why dont you go with the S2?

Is it necessary to have 28nm?

Thanks guys.

The mind boggles as to why they keep slapping those puny 1000W PSUs in these 1T boxes?

Now, if they could only update their price to a more competitive one...

 Don't have a Kill-A-Watt handy to measure power draw. It's performing as expected, at 1THs with the dragon image.

If i am not mistaken it hashes at 1t with the dragons firmware.

Is it hashing at a full 1T?  What's your wattage at the wall?

FWIW, the SD Card in my Qiangminer got fubar'd the other night. Loading the dragon image posted in this thread onto a new SD card got the system back up and running in short order. (Make sure you have an IP scanner to locate it's IP. If memory serves, I believe the image in this thread defaults to 192.168.1.163.)

I was being facetious.

BTW, does anybody know the actual draw at the wall for these clones?  I don't think it was ever mentioned in the OP.

Not that good luck with such price.   

Are these clones still in stock?  If so, are you still selling them for $2,650?  Good luck with that.

Another one that is trying to be you is Qangminer.  This is not you right?

Qianminer is not mine.The correct and only one is Qiangminer

Anyone know if it's easy to do solo mining with these ones, I need one of these for mining others sha256 coins...

What?

Is Qianminer your?

FAKE SKYPE ID ALERT!!!

My Skype ID is "qiangminer" = "QIANGMINER" the one and only.
The Skype ID "qianqminer" = "QIANQMINER" is not mine. It's fake and scam!!!

Pls, be careful.

 What is specifically not good ? My Qiangminer is working quite well so far. Look forward to purchasing another in the near future.

Mine is running right now actually.  Chris is my first name and you can guess what my last is LOL!

I'll post screen shots later and a pic of the unit hashing with my Dragon Miners (have 12 A1 clones right now).  But I booted it up, the the IP was justed as Xer0 had posted (192.168.1. the digits on front of the case), setup the network and added my pool information.  It's currently hashing at 1-1.02 TH/s for last 2 days.   

We both know what to look for, as we both been bitcointalked rip-off, by looks like "AvalonShenzhen" same page layout..Newbie
here some info and not good:

Buyers' status update

Hello Sir,

Are you working on a 3TH/s clone right now?

Thank you for your kindness

use this image for the miner
https://dl.dropboxusercontent.com/u/92967009/dragon_image.7z
use this program to insert image in sd
http://sourceforge.net/projects/win32diskimager/

Yeah do *ANY* of these manufacturers provide a firmware image?  My SD card went toast (tried several machines) and I have no image to go from.

Would it be possible to provide us a download link to a RasPi image we can use to restore our units in the event of an SD corruption ?

Thank you very much all you guys for sharing

https://www.dropbox.com/sc/d3d5ge332khfwx0/OUzzxha09j

Today, I received it too.

Thank you, Nattapon.

Miner arrived yesterday. Shipping was kinda late but hash speed at 1TH so far.

For changing a pool address,  stop mining first via Webgui, then change a pool address and save. After that, start mining again.

Some updates after 5 hours of uptime, mining difficulty 1024 shares.



I should note that I had difficulty getting changes to the pool settings to stick via the webgui, so I had to ssh in and configure the pool information with nano /var/www/accout.txt then shutdown -r now to reboot

User/pass is root/admin for ssh on these guys. You should have a number written on your unit and on the SD card. That is the last quad of the 192.168.1.xxx address of the system.

wink wink nudge nudge ... feel free to PM me 

Hopefully BTC goes up! I have 4.6 coins and would love one of these.

Thank you

Sorry for any inconvenience caused to you.
Right now, I've seen that your miner is at your country customs.
Hope to see a miner in your hand soon.

 

Thank you for sharing. I get it.
I will try to negotiate to the factory owner again.

You have to be the only person on earth that possesses all the versions of the A1 clone 1Terra miners!!!

 



ps. I am trying to catch up with you but I am still waiting for my tracking number .   

Nice man!  Thanks for sharing!

Keep us posting, this is interesting!

Package arrived ! Will see how she performs later today when I get a chance to set it up. No documentation. This is going to be fun !




EDIT: It's alive !

Well your boss sounds like a thieving asshole.

Here is a sample of how other companies (your companies competitors) distribute source code:
https://github.com/bitsyncom
https://github.com/KnCMiner/cgminer
https://github.com/AntMiner/AntGen1
https://github.com/luke-jr/BitForce_SC (note that even BFL has released source)
https://github.com/gridseed

I could go on, but hopefully you get the point.

I sent BTC to Qiangminer and got a DHL tacking number last Saturday.

He is very kind and sent my miner quickly.

But, my miner doesn't have pick-up message.

It just [Shipment information received] state.

It mean, he reserved DHL delivery and DHL didn't got package.

Qiangminer didn't reply to my mail from yesterday.

So, I can't get any update from Qiangminer and DHL.


If you consider this Group Buy, be careful.


I can see picked-up message in my tacking information. :-)

Sorry that I don't have enough power to push the factory sharing the source code.
I'm only a sales agent not the factory owner and the owner he doesn't care about share this modification
and spread them online. and I think another provider do same things like me.
Could anyone show up about dragon miner or other asic factories who share?

But what is the reason for having it locked?

Doesn't it make it suspicious?

 I can't say that I support this stance. IMO, if you can't publish your changes to cgminer, then you should not be using cgminer to begin with. It's against the agreement included with the CGMiner source code.

 It's poor form and disrespectful to the hard work done by the authors of the software.

We really can't sell at $2,500, we apologize about that. However, we can ship out on the next day after we confirm payment as well.
If we reach the gathering order of 51+ miners after group buy closing date. we will refund $50 back.


To.. Xian01

I think DHL should update your miner movement today too,
because I send it by the fastest express service of DHL (with high charge to me so).
From my export experience, sometimes DHL HK warehouse was overloaded with parcel posts so it maybe lil late.
I will pursue your express situation from my logistics service this morning and update you soon.

Thanks for the link, hadn't seen that.

A few questions about the miner that I answer the customer:

- source code for cgminer modifications is available where?

We can’t provide you source code for cgminer modifications. For my opnion, others factories are the same.

- circuit schematics will be provided to customers? His is required for maintenance and/or repair

We can’t provide circuit schematics as a secret of our factory. In case, it’s need to repair, pls send its back to us.

- what is required to 'unlock' a miner to allow overclocking?

For A1 chip, it is locked from the factory and highly recommended to do not unlock.
We had pretested and tried out in every ways and found out this miner is very stable
at 1TH with our spec of material. If you want to unlock for overclock, we recommend
to use AVALON GEN3 chip which is designed for overclock miner.
However, our factory still do not release the AVALON GEN3 miner, sorry about that.

- with several manufacturers producing these clones why should I choose qiang?
Web GUI is in Chinese, unproven, no LCD screen, 1kw PSU only (lketc dragons are now shipped with 1.2kw PSU)
and price is essentially the same.

We are 100% brand new and first hand product. We don’t mine with them waiting for customers come to pick them up.
We can provide a translation of Web GUI for our customers.
No LCD to reduce a cost because LCD don’t help to mine BTC ,just show stat.

For PSU, the factory has changed them to 1300kw PSU within box of 1100kw PSU,
because these PSU spec we special order from a PSU factory,
but they don’t have 1,300 kw box for a while. However you can prove by open the box or use meter.


For the price, we try to lower its as much as we can. We guarantee our good quality, good after sale service,
good material with reasonable price. We extremely cannot reduce price anymore.
It’s up to the customers to choose what product and service are suitable for them.
The only thing we can say is we really try our best.


Best regards
Qiangminer

i see an advantage here: Paypal - lets you use your credit card

https://bitcointalksearch.org/topic/worldwidebitmine-950-ghs-1500-usd-next-day-delivery-409701

Can you please specify " Considering 1tH/s rigs just became available for $2500 from competitors,"  ??

Who are they?

 Considering 1tH/s rigs just became available for $2500 from competitors, shipping out tomorrow, I can see your point. However, lacking a LCD is not a deal-breaker as I'm mostly monitoring these via web interface anyway.

 Still waiting on some movement of my DHL tracking number, and can only hope the lack of movement is due to it being Sunday.

Yes, and I ask you again, what is your advantage compared to LKETC?

You dont have a better price, neither an LCD display, nor reputation, nor a website.

Question again, why should I buy from you?

Dear, our customers

I'm going to answer every questions which are in this post, PM or Email.
Please kindly wait and be patience. Thank you very much.

Best regards
Nattapon

No, I mean $2,950 for 1 unit
but when I gather orders from every customers reaching 51+ units
the price will reduce to $2,900

Sorry for my poor English to make you confuse.

It says $2,950 for group buy of 6 miners minimum?

I can buy a single directly from LKETC for the same price.

You mean you you bought it for $2600?

Dragon is $3000.

Sent you a PM!

 How do you figure ? I've seen hosting deals for $2600, but could you direct me to a cheaper source for physical 1tH/s rigs ?

Hey this is not cheaper than dragon, and has no LCD.

Im happy with LKETC , why should I choose you?

Tracking number received And now we wait...

Right now I'm trying to follow your track at the logistics office.
I will update to you so so soon when I get it.

I apologize for your inconvenience

Should be able to use Google translate on the web UI

Hi, I sent BTC to you. 

I have received your both paypal payments already
and will update your miner status via this thread.

Thank you very much

Sent payment by paypal. Will update the progress on my sample order for everyone.

Hello,

I will provide an English manual for you and our clients since the WebGUI is in Chinese.
Don't worry about the language, I have many connection with English translators
My teams and I will give you a technical support enthusiastically.

Hope to deal with you too
Regards,

ํYes sir

 Have a thread going with Qiangminer via email, inquiring about purchasing a first run of these.

 I'm wondering if the WebGUI is in Chinese or English; I don't understand Chinese

 Hoping to do a deal via Paypal/USD.

paypal to [email protected] ?

Thank you and please kindly check your email.
Right now I have replied back to all emails and PM already.

Thank you for your offer.
I am replying your request via PM

Of course, we can meet at North Huoqiang, Saige Plaza.
What's the time and date that your friend available?
I will contact you via PM for more details.

Thanks
 

Please be patient. Give me a chance and a little time to prove myself.
Besides, if customers want to visit our manufactory , I appreciate and very welcome.

Dear, gallery2000

Sorry for my poor English that made you feel confused.
I've edited this issue already "The First 5 units for sample and review : $2,800 usd each"

Thanks miter_myles for your kindly comment.

Thank you for your consideration and good questions.
As I answer you in QQ, I do answer again here for others.

All the modules is 6 pin connections, the one u see as 8 pin,
actually another 2 pin are not connected. Connectors from PSU to power are about 25 pin.

In addition, our item is not overclock from the factory. One a1 chip's speed is 20-35 GH.
We set its speed at 32GH. So it made 1024 GH/machine. We don’t neither overclock nor underclock our item.
And definitely, we do not recommend you to overclock or underclock device.

If you want to overclock, we can make unit unlocks from the manufacturer for you in special case,
but the warranty would be canceled. By the way, the PSU may not enough to support the overclock,
so you have to change the PSU by yourself. The miner's power consumption is now 950watt
and the factory plans that the PSU may be changed from 1k Watt to 1100-1200W.

Finally, we do not sell products without PSU for lower price
because we have to test all miners for setting and running them before shipment.

You are in SZ

Can I send my friend in SZ to collect the goods and pay on collection?

I sent email to you.

I'll take one escrowed for $2800, or I'll offer to pay you BTC upon delivery of product, shipping to the USA, if you are looking for members to verify this product.

pretty sure that is the way around to gain trust... sell the first 5 to people cheaper so they can report back when they get it and everything is groovy

Another scam....there will never be any deliveries of any working miners from this.

Why does it cost more to buy more than 5 units?

In the pictures, it appears that each hashing module has a ribbon connection and 1x 8pin power input. I was wondering if all the modules require 8 pin connections, or will 6pin work?

I am curious since the picture appears to use 8pin on one or two modules and 6pin (without the 2 extra pins available) connectors for the other modules. The description also says "3 +12V DC input" for power; is this accurate?

Further, the PSU supplied is 1k W and the A1 is clocked for 1TH. Does this imply that the efficiency is better than 1G/W, as there is usually some extra power being used (to run control board for example)?

Finally, if one puts a more powerful PSU in, what are the options for overclocking/underclocking? Does the manufacturer put in a kill switch when one tries to OC/UC, or is it an easy task of changing clock settings and cooling the device properly? If you can OC or UC it, do you know to what value and what the power consumption is?

Sorry, I have no service on Escrow, paypal pls 

Can you take Escrow like Ognasty

My Skype ID is "qiangminer" = "QIANGMINER" the one and only.
