That is a good looking board, nice that you made it open source.
|
Message me if you have any problems

Wherever BkkCoins is now, i wish him all the best, and may he come back soon. Agreed. ------- Not sure how much support there is for chips from Avalon given what they have done to everyone. Plus the fact the chips "underperform" and are not as "cost effective" as Bitfury chips which are available right now. Personally I'd really want to support efforts like this if there are future plans to utilize other chips other than Avalon.

Nice! Is that a 4 layer PCB? What's the part number of that .9 volt power supply? Did you use the same PIC16LF1459 chip ?

Yes, for better power-distribution i choosed a 4-layer pcb. What's the part number of that .9 volt power supply?
PTH12040W => http://www.ti.com/product/pth12040wDid you use the same PIC16LF1459 chip ?
Yes, only small modifications to the "Clock Configuration Segment" (Chapter 4.1 of the datasheet) were necessary.

Do you have the ASIC's chips in 2 banks? Also what hash rate are you getting with this board ?

How did you get early access to the chips? When did you get them?

That's cool, but, uh...do you think you could get the Cointamination boards working before you dive into this project? A lot of us are really hoping for some success there.
With respect.

It is not like he is not doing this. He had this board about finished for some time now... If he wouldn't work on Cointamination it would be publish at the start of the week...

Yes, 2 banks with 5 chips each. I didn't had much time, but today i managed to get them hashing. The parameters and clocking are far from optimum, and as you see, it is not 100% compatible to the Klondike-driver yet. http://my.root4u.de/avalon2-firsthash.pngI will do further investigation tomorrow, and come back here with more results. How did you get early access to the chips? When did you get them?
I got them ~2 weeks ago for this contest: http://avalon-asics.com/avalon-gen2-55nm-open-source-design-contest/

design boards that fit in standard avalon casing! so we can scrap the old cards and get 4x80x1.5GH per unit.

+1 there are around 1500 Avalon units from batch #1,#2 and #3 Create a blade which can be used to replace a current one in an avalon and sell it at a price which leaves a 20-30% earning margin to the buyer and you can probably sell six thousands of such blades in a few hours... spiccioli

make same size as gen1 unit so we can reuse the heatsinks and contact ckolivas for firmware support.

I'd certainly be very interested in some of these boards if the price is right

can the 2nd level pcb be mered into a single PCB? having the extra steps of assembly will make costs significantly higher for this design. KISS method

The entire "second level pcb" is a standalone part.
