That looks like great!!! No fan thats a first at those speeds. Does it have ethernet connector built in?

yes. ethernet interface is built in the controller board.

[CroverNo01]

Looking good will be watching this one 

[dan99]

Ya, can't  ask for more, let see if they have good payment options and good price per gh/s. We need to see videos of your running unit and more photo please.

[innovation]

waiting for the good news.

... it looks he is welding their chip to testing board...

LOL

This micro or nano china chipization procedures

i Rusia but this very funy

Double lol 

[bclcjunkie]

great work guys... price them below btcgarden, asicminer and i'm sure you'll have plenty of buyers lining up. Based on your test the chip seems pretty good at overclocking..

An quick update

In the afternoon of 12nd Nov, After testing the single chip for over 24 hours and the speed in pool are all right, we decided that the chip can work stably alone. We tried lots of voltage-frequency-efficiency combination. Here are some of them:

	Vlotage(V)		Hash Rate(GH/s)		Total power(W)		J/GH
	0.75		1.60		1.07		0.68
	0.85		2.00		1.69		0.85
	1.00		2.50		2.82		1.13
	1.10		2.80		3.70		1.32

From the afternoon of 12nd Nov, we started to test the multiple chain mode of the chip. We worked on it through the night. We slept only 3 hours in the early morning, and got up work again. In this afternoon, we decide that the multiple chain mode works all right.

Below is the photo of the testing board we soldered and assembled. It runs at 1.6GH/s per chip (50GH/s per board), and it does not need fans to be cool ( 60℃ without fans) . However, we will still prefer fans added when it is mining, as the low temperature will help the DC/DC efficiency a lot. We will test the 2.8GH/s per chip(90GH/s per board) tomorrow. A young hardworking engineer is soldering it right now when I post When the chip is running at this speed, efficiency will be 1.32J/GH, but I guess the heat sank we ordered will handle the heat, with very low speed wind. The ambient is 27℃.

Congrats, looks very interesting. Out of curiosity, how big is your first batch, and what kind of production volume do you hope to achieve?

would be nice if first batch was 2500 or more.   no delays no bs.  if they ramped up to 5000 a batch and a batch every week they could sell them all. fast at the right price.

Looking very good

I'm very curious about the evolving tech specs you gave us.

Several questions:

1) How many board per system you plan to sell?
2) The voltage levels can be configured via cgminer settings, or need to be done manually (using potentiometer or dip switch)?
3) The highest voltage (1.10V) to product around 3.7GH/s per chip. Assuming each board has 32 chips, it will be around 118GH/s per board?

Hope you will have a good price per board/system. We want the "kit" or complete system.

Hope you will have a good price per board/system. We want the "kit" or complete system.

1) 2 blades combined into a independent mining "kit".

2) The voltage level will be fixed when we shipped out and cannot be adjusted without you manually change a resister on the board, which may need EE expertise.

3) At 1.10V voltage the chip runs at 2.8GH/s, it will be 90GH/s per board. After testing at 325MHz*8core this afternoon, we are now sure the chain of chips are working at this level, but the software on the control board cannot communicate with the chip properly. We are fixing it now.

Looking good, i will be watching this

I hate to keep asking, but any chance you're planning on doing bulk chip sales?

[BITMAIN]

Hi MrTeal, excuse us to keep you keep asking  

Will you sell your chips? document, testing chip etc.

Yes, we sell BM1380 chips. Documents, software are being prepared while we are still testing the chip.

Our github:
https://github.com/AntMiner/AntGen1

Please fill the form to help us centralize the testing chip request information, thank you.
https://docs.google.com/forms/d/1nh1mF2bAKjHnwx9o4wt_X3q_epPWndLxj-qGwgqxNlA/viewform

The earliest time we can deliver the bulk sold chip will be in around 50 days. The chip order we sell will definitely have a commit day from foundry, which means we will sell the chip only after the wafer starts fabrication.

Good to know...

[rob143]

This sounds great. I would be a buyer at the right price point.

[gwoplock]

i will buy if it's profitable.

[bitcoinlord]

It's cool that you replied with tech details. I'm an engineer, as I have my lab here at my office, which means that I can solder resistors easily.

1) 2 blades combined into a independent mining "kit".
2) The voltage level will be fixed when we shipped out and cannot be adjusted without you manually change a resister on the board, which may need EE expertise.
3) At 1.10V voltage the chip runs at 2.8GH/s, it will be 90GH/s per board. After testing at 325MHz*8core this afternoon, we are now sure the chain of chips are working at this level, but the software on the control board cannot communicate with the chip properly. We are fixing it now.

From your BM1380 spec sheet, especially the GH/s, A and W parts (table) as shown here:


Several more questions, to help us understand better:

1) 180GH/s system kit, based on 2 blades (2 x 90GH/s).
   Power: 3.7W x 32chips x 2 boards = 237W. With the controller (around 10W)  plus 5% extra for power losses, the total power requirement for 180GH/s system (kit) is around 280W. Am I correct?

2) In your specs (page 7), I see the absolute max rating for core voltage is 1.2V. It made me wonder if it's safe to push to 1.2V for higher GH/s rating with proper cooling in place?

3) Will your controller be able to allow for additional blades, such as 8 blades chained together to one controller? (8 blades x 90GH/s would give us 720GH/s hashing output.)

When will you post some prices?
