ASICMiner BE300S Samples Arrived, <0.2W/G Achieved at Board Level

[xhomerx10]

so? no news good news?
FC late login today.

It would be nice to hear some word from FC, atleast we would know that he didn't died at "drawing board"
We know that sample chips works better than expected, string design also works, so propably next news will be announcment of new product. Prisma 3.0?

The expected date of first batch is April 10 to April 30. Potential delay will be notified three months ahead.
Hashrate per device and power consumption:
  Normal mode - 1.0TH/s guaranteed. 1.6TH/s maximum. 0.25-0.27W/G.
  Turbo mode - 1.2TH/s guaranteed. 2.0TH/s maximum. 0.30-0.33W/G.

this is a update

 This is very good news but is it an official update?  Cand ai inceput sa lucrezi pentru Asicminer?

Many things don't add up, so I think this is speculative update. Having chips in February and miners in April? When everything is prepared upront? Chinese fabs can produce hundreds miners per day, next day after FC say GO there will be thousand miners ready on shelfs.

im not so sure about that.
from previous experiences, it seems their assembly chain is not that effective.
remember when they used to just send hundreds of screws to assemble the miners they could not handle by themselves?

"Burn in" ...

Lets hope they stick to self mining/cloud/bulk chip offerings. They obviously can not handle customer service when selling to individual miners. Let companies like SP-Tech and Bitmain sell to the general masses.

Ohh, right. Forgot that magic word... But history of AM doesn't show evidence of such a practice... As hdbuck said they even hadn't time to screw screws..

Where is the 24 chip board?

on the tank track road towards tibet

24 chip (6 chip chain x 4) test result posted.
The mosfets and big capacitors are safely removed due to the constant workload of BE300.



Results:

273.60GH/s | 0.38W/G
176.64GH/s | 0.31W/G
155.04GH/s | 0.27W/G
118.56GH/s | 0.26W/G

With more accurate control on the variance between chips we could in principle gain less power consumption in advance.

It's right ^there^.  Duh!

Any more questions ChoadStress?

It's seem that the color on some area of the board become darker. Maybe due to high temperature.

Shadows? It's such a crappy picture, it's pointless guessing at that...

There is only a fan above cooling that board, and they tested it at 273 GH/s - 11 GH/s per chip.
Single chip board test report was up to 7.2 GH/s per chip.
They must have stressed this 24 chip board up to the limits.

Im gonna guess its solder flux.

ROADSTRESS..... where are you?

I am right here don't worry. Only took FC one full month to publish the results. If you 2 are happy that AM has a 0.3W/GH chip for at least 8 months from now then I'm glad for you   Time to buy some AM shares!

Looks authentic - photo taken 2015:01:12 15:28:21 in Binhai Ave, Shenzhen according to the EXIF information.

I wonder how well the mass-production chips will handle dissipating 4W each, being a different (smaller?) package and all.

great work friedcat! my prismas are working very whell and whainting for your new release!

[Dexter770221]

This chip looks very promising for AM. It's good at both ends. Efficiency and performance if needed...
