Topic: [Work in progess] Burnins Avalon Chip to mining board service - page 139. (Read 624197 times)
Hopefully the assembly and payment gateway are good to go soon. steamboat's USA group buy opened their payment gateway today. Chips may be shipped very soon since samples were projected by Avalon to ship 3 weeks prior to the order. Time crunch time!
Burnin must have the hands of a surgeon, soldering that. 
Took him like... the whole afternoon

Burnin states that the chip runs to hot to have proper tests at 256mhz, so thinking that it will be possible to run these things without appropriate cooling is a bit of a pipe dream in my opinion, especially for anyone looking for that magical 450mhz I've seen posted in another thread.
Yeah, but what cooling was he using at the time? It was a test - he may not have had a full size heatsink attached.It was a test with chip in 'deadbug' mode:

burnin already addressed power on the previous page. Upped it to 3A per chip.
and even more important than the cooling, will the power design of the board,(regulator, caps, resistors, ect....) be able to keep up with the increased power demand per chip as they are over clocked? Looking at Bkkcoins project he mentions that he believes it would be possible but by reducing the number of chips on the board from 16 to 14, or spend additional money on different parts on the board to supply the power.

was wondering how long it'd take people to notice ( and more importantly share the constant that we've released on github.)
the number you are all aiming for is 450
of course, that's not really possible on just air cooling.

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.

Exactly, I wanted to point this up as well. I'm sure there is a significant part of customers who would like to see some detailed information about additional equipment necessary to run Bitburners, like proper power supply, connectors, cables, usb-stuff etc. I know there is still time but it is crucial to have everything ready when the shipment will start. I think burnin should post a detailed guide covering this kind of stuff because some things may be confusing for less experienced miners.
Guys, I think you need to wait until burnin launch website. All the necessary parts including cables and power supplies (most likely) will be available. Or at least will be available images with instructions.
Looking at the PCB, there are lots of power options. An ATX psu being the obvious one.
I would guess when the web site is up to place orders, it will become clear what you need.

It would be very important to know what is exactly needed. What kind of connectors, Power supplies
USB cables and so on. Does burnin also sell these things? F.e. What is needed for 4 20chips Boards?
Excuse me if those questions were already answered.

Looks like the first batch of chips from Avalon will be shipped in a week or two. :-)
Thank you mikep2012 and cimpex
Well i thought that i would share the info from here: https://bitcointalksearch.org/topic/m.2572272
450Mhz? really? 2.5Amps can't be enough for that, In sight of that I've bumped up the specs for the regulator to 60Amps total. (3Amps per chip)
With different inductors i could push it to 80Amps total. (That would be scary 100Watts per module
)for 450Mhz you will need water cooling, but the change is very nice!
Is this for sure? I mean i even read someone took the heatsink away form an original avalon and the heatsink didnt even has contact with most of the vias there. So is it for sure that the heat is so bad that air isnt enough? I mean thats not a gpu that is very hot from the start, its a complete new tech that isnt even fully explored. So i can imagine that the designs that burnin and bkkcoins create will give some surprises maybe.

I`m wondering where can one buy those metal (polls) between the boards + fan holding parts.
this polls are called "brass hex standoffs".
