@Kernel32 who are you? You have few posts and you only joined in April this year. Why should anyone trust you?

I don't see the problem with this group buy...best case scenario we get miners that are superior to avalons 100 days from now, worst case scenario we get our money back
Worst case you've locked up your money for 3+ months and have to pay John's escrow fees.

I have to say that I am almost blown away by the amount of butthurt! Yes, we get it. You haven't gotten your BFL miners yet, cry cry. The chips are a PROVEN design, delivered by GLOBAL FOUNDRIES! BFL and their development delays have nothing to do with it. Jeez, you cry all over the forum, how about sticking to one of the other 1000 threads about BFL orders?
Global foundries can reliably make chips.
If you could order the chip direct from GF without going through BFL, then you would have no worries (other than the chip being sensitive to heat damage due to poor design, or something weird like that). Since BFL is involved, delays and broken promises are to be expected given BFL's track record. The exact form those delays will manifest as cannot be predicted.
It would be a delight for once to listen to BFL say "Two more weeks! (TM)" and have it arrive in less than 14 days.

This^^ bfl may be incompetent, but the combination of global foundries, burning and bkkcoins is not 
bfl is just going to be the middlemen between global foundries and the persons making the boards

First they should ship all the other units !!!
Unbelievable how they treat the whole bitcoin community !!!!!
I m surprised that they are not scared of their own customers

are you going to sent half of the sample chips to burnin and the other half to bkkcoins?
June 11, 2013, 07:30:09 PM
i have a slight interest for about 500 chips. Still thinking about it though.

We received BFL reaction regarding sample chips request and hash test of produced chips before escrow release possibilities.
I'm glad BFL agreed on shipping 65 nm chip samples to community mining board devs.
If developers get chips and quality documentation (*might* be even this week), they would be able to estimate board design/prototyping period(/feasibility). That is crucial info to have before actually opening the group buy.
Sample chips distribution is my top priority right now.
BFL also agrees on HASH test prior to escrow release. I would like them to make few Short Boards (Jalapenos) available for testing. (If there is no 65 nm community mining board at hand already.)
Mixed lot structure:
- 60% Grade A (16 engines - equals to 4.00 GH/s)
- 20% Grade B (15 engines - equals to 3.75 GH/s)
- 15% Grade C (14 engines - equals to 3.50 GH/s)
- 5% Grade D (no less than 12 engines - equals to no less than 3.00 GH/s)
Clock rate (speed) of engines is between 250 and 294 mhz. That means about +/- 7,5% individual hash rate fluctuations. Price for 60/20/15/5 quality lot is $75/chip.
I have yet to find out whether Grade of the chip is known prior to usage (Group Buyers would be compensated for buying lower quality chips) or not (lottery style).
I get quite a lot of PM's of people asking how to join the Group Buy. Please notice, we are still in preparation phase. Making sure our deal with BFL is safe and sweet.
Some also asked about shipping/VAT, whether this is a US/EU/Asia based group. Well, this is international group. All of the chips will be sent from warehouse in California directly to costumers/chosen board manufacturers with possibility of merged shipment to EU.
Thank you so far. I'll keep you posted.

I can provide you with sample chips prior to the chip purchase, yes. It would obviously be a limited number of chips, but we can certainly spare a few of course.
How are you proposing to do the random chip selection hash test prior to release? In principal I don't have a problem with this, however there are some practical pitfalls here, chiefly what if you don't have boards or a test rig ready to do a proper test of the chips, do we then wait until you are ready?
I hope to have the reference documentation done this week. We are pretty time crunched getting the singles and MR ready to ship, which should also start this week. Once that starts rolling we can focus more on the technical documents.
By now, I'm sure you've seen the new pricing and the fact that the chips will be shipped as a mixed lot, so it probably renders your final question invalid. If not, let me know.

Interested. I can even help you with EU build boards... Probably also some R&D making batter boards. Plans just need CE markings... But I'm limited in a amount of money for this.
June 11, 2013, 12:26:12 PM
So... The chips will be shipped and hashing before any non-Jalapeño customer receives their unit, right?
Cool.
Cool.

Encased in a mineral oil bath?
To move the heat away from the chip,:
One should use copper. Copper has far higher thermal conductivity than mineral oil (like 50x). So, more chips will need more copper sinks in contact with them.
To move the heat away from the copper:
If you go with water blocks (or mineral oil blocks), then you can use less copper and move the heat away from the copper faster with water (or oil). I don't think you will save money or power consumption that way since the plumbing adds cost and complexity. A bit more copper with some fans for each cluster of 2 chips should be sufficient.
I would simply buy a Corsair H60 or H110 and use thermal adhesive to mount the block once I was satisfied it could do the job. I mounted a H55 to my 7870 using zip ties and it never went above 57C at 1225mhz core (tahiti chipped version) so I already have experience with conditions that aren't exactly ideal and it worked out just like my custom water loops have and honestly took far less time but once the adhesive is used and sets there is no going back.
An H110 would almost certainly do the job, but that is an extra $130 per chip cluster. That cooling expense drops BFL's price/performance below Avalon's.
Plus, scaling chip clusters would be hard with all the extra plumbing required.
True but if you can get away with an H50-60 sized cooler they can be had at $40-50 for restocked/refurbished units as well as the Antec 620s. Consider that with possibility of overclocking and you may have potential worth looking at which IMO gives reason for second thought as far as Avalon vs BFL processors once widely available. But for now I would stick with a company that delivers more consistently.

I'd be interested in around 1,000 chips towards the group buy.
https://products.butterflylabs.com/65nm-asic-bitcoin-mining-chip.html
It looks like they are for sale now. $75/each (Much better price) What is the status of this thread?
I did hear that prior to the price change they would be giving discounts based on quantity, hopefully this translates into even better prices for the group buy.
LoL!https://products.butterflylabs.com/65nm-asic-bitcoin-mining-chip.html

They aren't selling at all compared to the Avalon chips which have a known working implementation.
Seems they slashed the price by [very roughly] ~25% to try to lull people into buying chips without the board....Yikes...
Reeks of desperation.
The old offer:

Butterfly Labs will begin selling bulk chips to individuals and companies starting in June, 2013. Chip delivery schedule is approximately 100 days through end packaging once your order is placed. We will be providing reference documentation, reference design/schematics, and foundry receipt/documentation.
Grade A chips have 16 engines and will do 250 MHz comfortably, equating to 4 GH/s per chip.
Chips will be graded and priced as follows:
Grade A: 16 Engines - $97/chip
Grade B: 15 Engines - $93/chip
Grade C: 14 Engines - $89/chip
Grade D: 13 Engines or less - $83/chip
Our chips will be provided in minimum lots of 100 with the following price structure:
100 - 999 chips - Regular Price
1000 - 9999 chips - 5% discount
10,000 - 99,999 chips - 10% discount
100,000 or more - 20% discount
Chip orders will require 50% down and 50% upon order delivery. Payment can be made via BTC (preferred) or bank wire.
Advantages of BFL chips:
1/2 the power usage per GH as the closest competitor
1/10th the silicon area per GH as the closest competitor (Very high performance density)
You can use off the shelf heat sinks depending on your chip layout due to FCBGA package vs custom underside heat sinks as required on some QFN packages. You don't have to design and manufacture heat sinks!
Proven design currently operating in the field and ready to go.

I noticed on their site it now reads that they are selling mixed lots...?
Does this mean they are no longer sorting out the Grade A's from the D's or what?
Is this going to be like an easter egg hunt where one has to figure out what chips are grade A's? Also read yesterday that they want the buyers to create their own firmware. Kind of a tall task! (Can't they just give the board makers their own reference firmware(s)?)
If they keep making it harder and harder to turn those chips into actual mining rigs they might as well keep slashing the damn prices! Gonna need to pay a whole development team just to figure it all out.
June 11, 2013, 04:46:51 AM
Who would buid a miner out of that chips? So for 40gh it would be 1000 $ plus 1000-2000 $ or even more?
June 11, 2013, 04:39:34 AM
Oh, I remember a story about a 1000 BTC charity bet and BFL founding their own "charity". Guys, buy those chips from BFL and we will see in 100 days if BFL found a way to weasel out of the deal and keep your money.

I think he passed his limit about a week ago. He's on an epic bender at this point.
June 11, 2013, 02:15:41 AM
BFL has shipped 3 months worth of Jalapeno orders in about a week's time. This is why Bicknellski and his fellow BFL trolls are getting desperate, leading him to search for all terms BFL, and post nonsense in every thread he can find, including posts that have been dead for months. Also why he's clearly over his limit on the 'rageahol'...

Where are the fucking the miners?
Where are the fucking chips?
Where are the fucking design specs to make a PCB work with the chips?
Which kind of fucking chips will they ship grade D?

Gee, wipe that foam man...just a little more...there.
I can understand complaining, but you just went berserk there, red eyes and all.
I thought you were a teacher or something
