Changed that dammed chip and:

SUCCESS!







But 5GH, must have been a full board then or?

Now this is fantastic news, can't wait to oc these puppies, congratulations on all your work!  Love that hw number.

You should be re-posted on any lists as hashing as well.....

Wow, didnt know that its so featurerich... and all 4! power connectors are for cables that goes horizontal right? The left 3 for sure but im not sure with the right one. But i guess the second right one would be the one to use with a ATX-PSU.

Do you mean the green power connector goes with ATX? I wonder how to split power from ATX to multiple boards, like 14? What additional cables/connectors do we need?
No, the connector on the left side of the green connector. Im not sure what the green connectors cable would look like.
You would most probably split the power from a psu via y-cables.

Putting a heat sink on top will restrict the airflow over the pcb. The pcb has internal copper layers ('ground' is usually designed as a plane) which act as heat spreaders as well.

Do you say the other side of the pcb needs airflow too? I intended to force the airflow from the fans through the heatsinks only to maximize cooling. Do i have to rethink this?



The chips are designed to release heat out of the bottom, and putting a heatsink on the top of the chips can restrict convection and cause the chips to overheat.  The top of the board doesn't need additional air flow AFAIK.  The fan on the heatsink should create enough airflow around the board that all you need on top is convection for the other parts.  That is, don't cover it up, but no need for anything else.

So it doesnt need airflow but then you say the fan will make enough air. But what will happen when i force the airflow ONLY through the heatsink. You know like creating a tunnel. I would like to take 2 miners with heatsink and put them together tight with the heatsinks. Then put a fan on the side and somehow build a tunnel that only allows the air flowing between the ribs of the heatsinks. Im not sure yet what material would be best for this but i think it would greatly effect the cooling because i think otherwise most of the air is going useless the easier way.
So would that be possible or is it needed to put a little bit of the airflow to flow above the other sides of the boards.

I believe convection is enough for the top of the board.  Just don't plaster over it or cover it with a blanket.

I, for example, bought an airline ticket to Germany to pick the modules by myself from Burnin.
So you already know the date? Wink


mid july if avalon delivers on time. if not, well, I guess I will stay in Germany for 2 weeks.

i just imagine the same story with BFL Cheesy
With a guy on front of the door for the last 9 month hahaha

Correct me if I'm wrong but Burnin hasn't taken orders yet right?

And you've locked in to ship to Burnin? Arn't you getting ahead of your self? Burnin hasn't officially listed the prices for board yet right?

Or have I missed some critical BitBurner information?

Cheers,

What you say is true, but irrelevant to some.
I based my decision on quality of workmanship mixed with gut feeligs.



indeed.

Nearest us - USB, Power, Power & Power.  3 connection options depending on how you intend to power it.
Left side - CAN Bus header connector, and what looks like a cooling fan power connector.

The big white connector in the middle is 6-pin PCI-E connector, which is the easiest connection option with ATX-PSU.

Green chimney seems to me like simple screw terminal.

The CAN-Bus is the one that connect the miners together and is connected to a raspi or a notebook at the end to run the miner software?

So, reading that I get that the group buy is over.  No further orders being taken.  If you ordered chips, then you can get burnin boards, otherwise not.  Correct? 

As I understand it, only SebastianJu's groupbuy is open on batch 6 currently. But Avalon's chips are "Out of Stock", and since SebastianJu doesn't purchase the chips before hand, batch 6 is at a stand still.

The european groupbuys will, together with zefir, order one or 2 batches once the avalon shop opens again. 24 hours or so after its back. So at the moment one could say that all orders that come in will be ordered at avalon shop at the end.

Putting a heat sink on top will restrict the airflow over the pcb. The pcb has internal copper layers ('ground' is usually designed as a plane) which act as heat spreaders as well.

What are these 4 slots? The middle at the end is for power? What about the other 2 at the end and the 2 at the left side?

Offtopic: Its funny how much such pcb's remind me of cities. Streets, flat buildings, oil containers, foundries with chimneys... Smiley

I hope that no magic smoke comes up from the "chimneys"  Grin

steamboat has a batch six groupbuy that's still open.
