Last edit: January 18, 2015, 06:12:24 AM by friedcat #1

of our verification sample, BE300S, the silicon results matches the simulation results faithfully,

and even outperforms our simulation in some cases. BE300S achieved the lowest energy

consumption per gigahash in existing market, getting the joule/gh ratio down below 0.2.



Furthermore, our string-based power solution eliminates almost all power losses and almost

all electric components on the board. Therefore on-wall power consumption would be very close

to (on-chip power/PSU efficiency), and the overall system cost is squeezed to its minimum.



Name: BE300S (Sample)



Technology: TSMC 28nm HPC



Package: FCLGA 5mm x 5mm



On chip efficiency (first board):

3.0GH/s | 0.1872W/G

4.8GH/s | 0.2275W/G

5.2GH/s | 0.2469W/G



On board efficiency (average of 4 boards):

2.8GH/s | 0.1961W/G

3.2GH/s | 0.2026W/G

3.6GH/s | 0.2095W/G

4.0GH/s | 0.2145W/G

4.8GH/s | 0.2204W/G

5.2GH/s | 0.2257W/G

5.6GH/s | 0.2314W/G

6.4GH/s | 0.2363W/G

6.8GH/s | 0.2439W/G

7.2GH/s | 0.2495W/G



24 chip board efficiency:

118.56GH/s | 0.26W/G

155.04GH/s | 0.27W/G

176.64GH/s | 0.31W/G

273.60GH/s | 0.38W/G



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



We are still testing more voltage-frequency combinations, as well as more chips.

But the test results are stable and solid so far.



After the thorough testing of single chip boards, we are going to test boards with chained chips.

More data and pictures are to be updated. We are glad to announce ASICMiner's 4th generation chip.

if i'm adding up right - that chained board (filled with chips) should be ~135GH/s @ ~32w?

Network is going to go mental. I can't wait to see what the competition brings to the fore. tips 1APp826DqjJBdsAeqpEstx6Q8hD4urac8a

LegendaryActivity: 2786Merit: 2636 Re: ASICMiner Announces BE300 Bitcoin Mining Chips December 10, 2014, 08:08:08 AM #5 so asic miner is promising a .3 watt miner at the wall socket.



if you could build one that works and does not burn up caps . I will buy it. but after my tube and then my prisma troubles I will wait for others to buy them first.



would be nice to have a .3 watt miner. an evga 1300 g2 could power a 3000gh unit easy.





Right now I can run 2444gh on an evga 1600g2 .. I can do this by under volt of the sp20. 2 units will go to about 625 watts plus 625 watts = 1350 watts at the kwatt meter plug



So this is about the best a home miner can do today on 1x 120 volt 15 amp circuit. need a 1500 watt psu to do it.





If you can do .3 watts a gh it may be possible to do a 4th machine for 1200 watts . that would be a nice improvement.. it would allow the evga 1300 to be used as that psu can do 1200 watts non-stop.



lets see if you do it.



I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

There are two reasons contributing to the current RMA problem of BE200-based chain design. The first is firmware problem, which we solved for Prisma 2.0 and are solving for Prisma 1.0 and 1.1. The second is that BE200's load constantly changes when switching task, introducing some big ripples in the whole chain and making the board unstable. It is also largely solved for Prisma 2.0, and is going to be totally eliminated by BE300 since its load never changes.



Also for chained design the output voltage of PSU, instead of software controlled DC/DC, determines your frequency and efficiency. For example, using a 12V-output PSU results in a higher frequency but higher W/G compared to a 11.5V-output PSU.
