Great job much cheaper than current alternatives.  What hash rate have you been able to push all 8 chips to?

What we need for make it hash?
Only fan cooler or thermal tape? Also

It says custom code. Does it still use the same protocol over a virtual serial port to be compatible with the same mining clients that support BFL's products?

What about Z-Link, how is that exposed over the protocol?
Hi DrHaribo, it currently uses the same protocol as BFL and uses the FTDI VCM drivers (or the WinUSB ones for cgminer). We're looking at ways to extend the protocol to allow the extra features / reporting available on the Chili to be exposed through the mining software.

Z-Link isn't yet. I'll let Chip Geek explain that better.

MrTeal, et al...

Great job!!

I have additional chips arriving in November.  Will you still be selling the boards then?  I would love to get more boards!

I am selling my 4chip slot for 1BTC right now, 1st and 2nd half of the payments paid.
This is hashing power equal to 4 x 4 GH/s = 16 GH/s

You can PM me if you are interested.

                                     
SOLD, THANKS

Anyone is interested in chips?  I still have 48.  16 chips for BTC5.5, or BTC16.5 for all 48

Fully paid. Shipping next week.

For those looking for coolers for these units, to save you all the research, this one is compatible, high performing, cheap and can be bought with BTC! Cheesy

So unless you're going for water-cooling this is probably the way to go:

Looking very good MrTeal!  You two did a very good job from the looks of it.

Got a question about shipping from those of us that were in the group buy and paid $56 a chip vs $50 Actual cost and that extra $6 per chip was to be for shipping our completed boards correct?  For Example my 32 chips X $6 (Extra per chip) = $192 Extra which is a pretty good chunk of change and would surely hope we don't have to pay anymore for a reasonable US shipping option.

Thanks again.

@Ridicuss, shapemaker and any others:

I have a lot of chips, fully paid for and being delivered with the group buy that I am open to offers for. They are already being delivered straight to MrTeal for assembly in the first batch, so no escrow/address changes would be necessary either, so it would be a very simple transaction.

They will be part of the first assembly batch that MrTeal is discussing, so this is a chance for a total queue jump, with chips delivered as he was saying in the next few days. As I said, I have a lot of chips, but not an infinite amount, and I don't necessarily want to sell them all, but PM me if this is of interest to anyone and we can discuss. Multiples of 8 only obviously!

One thing I will say though, is that any sale must not inconvenience MrTeal in any way, as selling these on was not part of my original deal with him. I don't want splitting orders to be of any inconvenience to him whatsoever, and the logistical stuff can be a real pain. This might mean having all my miners assembled and shipped somewhere (within the US) first and then the order split and shipped on to people so as not to cause any hassle. This would be done with a respected member of the community though, and I'm just saying it now, both to forewarn people, and to reassure MrTeal that this will not be an annoyance to him as he has been super helpful and super professional through everything (as I'm sure you can tell from the OP!)

Hashrate & powerdraw Huh

Probably depends on the number of chips. Looks like you could put up to 7 chips on there, but I imagine it would work with 2-6 also.

Nice work.

Working on getting some videos up of the production board. In the mean time, here are some of the test board.
Some videos. The first one is kind of a nominal load for the board. 107 hashing engines, setpoint of 283MHz per engine to give 30GH/s. Everything stays nice and cool, the board draws 130W at the wall. The cooler is a Hyper 212 Evo, and there's a couple little stick on GPU RAM heatsinks on the bottom under the mosfets, with a little quiet 80mm fan blowing towards them. The mosfets are 125F.
http://youtu.be/VOOGvlpNwws

This one is what I'd consider an overclock. 1.15V on the chips, with the same 283MHz nominal setpoint. 38GH/s and the mosfets got up to 175F. If you plan to do that constantly you'd probably want to invest in some proper cooling and airflow for them. Pulling 220W from the wall, so a big power penalty for those extra 8 GH/s
http://youtu.be/cCqiCodE12Y

I've found  1.1V on the ASIC to be a nice compromise for the future, with 35GH/s and 180W draw and things staying much cooler.

My test board has been burning in for almost a week now at 35GH/s and 180W.

Thanks for the info!!! Wink  Same draw & hashrate as my BFL 30GH'er  Sad 

The profit margin will be shortlived at about $800 for 30GH..I payed $650+$95 extra shipping for mine...but I got it on July 1st, .10BTC per 24hrs ATM  Sad

Looks great & cool idea using PCIE 1x to set in a PC slot  Wink

I got 16 chip credits for sale BTW....PM me if anyone's got an offer  Grin

Can't wait, this is such a cool project. Looking forward to seeing cooler and case recommendations.

I take it members of your chip group buy will get in the first batch.

I run Linux on my abacus.
I'm confused... do we need to supply our own chips, or are you providing them?

What is the full cost of a board, all included, if you supply the ASICS? Where are you located at?

EDIT: it's quite impossible to buy chips for this at such a short notice, so it would be good to have an all-in-one board choice to buy.
At this time we aren't offering any completed boards for sale, you have to provide the BFL ASICs. If you don't have chips but are interested in making a purchase, email me and we can discuss lead time and what is possible.

Thanks for the answer. I'll pass, getting the chips to EU and then back to US (where I am guessing you're located) would take prohibitively long, or be ridiculously expensive Sad

Had you had completed boards for sale, I'd have snatched a few. Good luck to your venture Smiley
