[Work in progess] Burnins Avalon Chip to mining board service

[sprint347]

Who wants to sell 10x chips?

[driksson]

this looks great. question, i have group buy from steamboat who i believe share the groupbuy with sebastianju, i can still ship the chips directly to you right?
Overclocking, is secondary right, you focus on making a stable 1.0 and then focus on maybe doing overclocking?

Burnin is doing his job sooo much better than BFL ever did !!!! THX 4 ALL THOSE FANTASTIC NEWS & PICS

Wrong yardstick.

He is doing a better job than Avalon.

great work burnin! I keep my fingers crossed for you!

No, you have to think about that NOW. You can't just create a new rev. That would be a completely new board if he didn't think about it now.

Crypto Porn, love it!

[Foofighter]

great news burnin!

[Schrankwand]

Crypto Porn, love it!

Crypto Porn is the order window together with "Hashrate 5.1gh/s, uptime: 72 hours, HW: 0"

Not so fancy, but decisive

[Knecke]

Burnin you are a great guy with great skills, i dont need your work but i followed your thread and you have achieved big milestones!

Proud of this german guy!

ANN: BitBurner water cooling solution coming soon!  

Made by german cooling experts:

http://www.anfi-tec.de

They look pretty expensive to me. Any price range?

Anfi-Tec does look expensive because the motherboard and CPU-coolers are produced only in small batches.

A watercooler for BitBurner will be produced in mass customization and will be low priced.

Just a quick status update:

Bringing a prototype like that takes its time, thank you all for your patience.
I verified most of the functions now, and there were some changes that will find their way into the next revision
Hit some problems with the quarz clocking the micro, it would not always start to resonate, so I changed it to an Oscillator.

Power supplies - all working as expected
ASIC Upstream - working, stable
ASIC downstream - unstable, investigating
USB Connection - working
core voltage adjustment - working
CAN-BUS - in development
Temperature/Voltage sensing - in development

I had it hashing for a bit but the return interface for the nonce  is not working stable at the moment. (about 10% HW errors)
I know whats causing the issues, have to change a part to get rid of them. (in the mail for Tuesday)
Power consumption at 5.1Ghash - ~36Watts

This is what we've been waiting !

do the chips really transfer more heat into the PCB than to the upper side?

Let's turn it upside down to be sure!

Yes, they are designed this way. And you shouldnt put a heatsink on top. Yifu said this will have a negative effect instead.

hope he is not. hope is thinking how to cool them properly and give us max OC chips

I agree. In this time-race there will be no time for a revised design later. If burnin is thinking on OC capability, we will all appreciate if he can add that to the boards in this time before Avalon starts shipping batches. New designs and boards then - for chips gen2

Thanks.

Theoretically it is sufficient, but its at the limit particularly regarding to the efficiency. I would suggest the next size that is >= 850 W. The 720 W also has no buffer for possible overclocking. But even without overclocking I would suggest a larger one.
