My design is spare-no-expense, build for resiliency and reliability.

This is awesome.  Thanks.  I appreciate the forthought you have made into the resiliency.  Really looking forward to getting my boards.

Overall Project status:
Done some more work on the Firmware, it now works flawlessly with cgminer.[/b]
The Prototype will not arrive until mid week due to problems with my manufacturing partner for the protype.

From a guy like you are I didn't think is possible to give any less then excellent performance.
Just wanted to say we all appreciate your effort. Thank you for what you are doing burnin.

Small donation coming your way.
Sorry it's not more, it is what I can mine in one day and still have to gather and buy one chip more.

@SebastianJu
What was the cooling system of that overclocked AVALON?

Sorry, i dont remember. Someone posted 2 links for threads here in forum where 2 guys showed their overclocking tests or so.

[SebastianJu]

@burnin... I now read that avalon miner were successfully overclocked to 395, stable at 375MH/s or so. From 282MH normal. Now BKKCoins thinks about how to change the layout of the board to meet the higher power supply needed.
Are the bitburner already ready for those high overclocking or would there a change needed because its otherwise not possible. I know overclocking is planned but i believe bkkcoins already had planned it too even though now he needs to revise his board.

My design is able to provide more current to the chips then bkkcoins (2.5A vs 2A per chip).
Therefore i don't see reasons to increase that even more.

Sounds good. 25% more current. Of course bkkcoins has 4 chips less but its still better.
Im interested to see and compare overclockingtests of both designs.

[makngeerwork]

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.

Looks like good news!  Lots of oc'ing headroom, let us worry about cooling these things.

What a tease BitSyncom is, lol.  I would love love love a unit at that kind of hash, but would the unit need to be submerged in oil perhaps?  Can't imagine even water cooling would be of much use at that output.

On the side, I wonder how long they had that chip stable at 450 for before it went supernova

Hey just a little question.

I have 2x 10 chips from differerent groupbuys and I want to order a 20module, there should be only a few days difference between.
Can you just store the first 10 chips to the time the other 10 arrive?

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 )

I wait until all chips needed for an order are present.
If you want per batch shipping do separate orders for each batch.

[Kiders]

I`m wondering where can one buy those metal (polls) between the boards + fan holding parts.

My current order status from sebastjan is 20 chips in batch 3 and 20 in batch 5 . You will send the batch 3 board with 20 chips asap. and when i get the second board from batch 5 i`ll be able to put them together like on this picture right?

this polls are called "brass hex standoffs".

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.

[RoadStress]

Well i thought that i would share the info from here: https://bitcointalk.org/index.php?topic=242423.msg2572272#msg2572272

[Kiders]

Thank you mikep2012 and cimpex

[FlappySocks]

Looks like the first batch of chips from Avalon will be shipped in a week or two. :-)

[biddicoin]

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.
