Quit? Let the riot begin:

The Firmware is not yet production ready cgminer throws a shitton of errors on starting.
AND the chip currently runs at 128Mhz because its not properly cooled, i have tested it at 256mhz too and it works but its too hot for long tests.

Now the bad news:
I will very likely not get the boards tomorow so we have to wait until Monday.

What kind of hashrates do you see at 256mhz?

Should be 256MH/s

One (double) sha256 per tick...

correct, for my long term tests i am running 128Mhash(Mhz).

Lovely job burnin. Really appreciate it. Thanks.

Also I have got some inquiries.

This is a quote from OP:

# CAN-Bus inter-module communication (Only one USB connection for up to 32 Modules)

and then in the very same post 7 lines and 2 pics down:

Stacking will be similar to the cairnsmore boards from Enterpoint.
The CAN-Bus module connection will allow modules to form a big cluster like the Avalon machines.
That way you need only one USB-Connection for up to 16 Modules, maximum bus-length >10 Mtr.

So the question is: how many modules you can connect over one USB?

Is it 16 or 32 modules?

And does it make any difference when the module is 10 or 20 chips?

Also as you said earlier...

I think i'll go for a ~850W, gold rated, single rail PSU perfect for one tower of 16 modules.

...I take it you meant 16 modules with 20 chips per module correct me if I'm wrong.

Also in that case (16 modules with 20 chips per module) what other cables (and how many) you need ?

Oh i really need to update that post!
Let me illustrate:
The 32 (10 Chip boards) / 16 (20 Chip boards) Limits comes from the maximum chip count in the Original Avalon units.
Because I use the same interface i currently stick to those numbers.
The protocol could support more, and i'll try to add support for even more then 32/16 but I can not guarantee it.
(CAN bus could be up to 30Meters long)
And the USB cable can be plugged in at any point on the bus. (Start, end, middle, somewhere)

I am currently working on the CAN protocol actually.
Thinking about posting a picture of the test rig, but it is a truly horrible mess of wires.
I don't want any of you to think the end-product could look even remotely similar to that thing.
