This is hilarious... I actually have some BFL hardware and even I think this means they are finished..  They are obviously trying to move payments to a medium that cant be refunded (bitcoin or wire xfer).  They are using a design which alot of us *know* cannot dissipate that much heat, and they are moving at a snail's pace with current orders.

Guys... Ive never said this before, but i believe they are on the virge of folding and taking anyone who preorders money with them..

Regarding power consumption, Radeon 6990 both consume more power than our card does, the very reason we took this design approach.

Nasser

EDIT: Corrected '5970' and '5870' to 6990

Really?  Why would it be PCIex16.  I get the idea of making it PCIe so using standard motherboards to densely rackmount.  By why PCIex16?  Using a x1 slot would allow more cards per mother board.
People still have those riser cable from GPU mining rigs Grin

PCIE x1 would work fine with riser cables.  BTW it appears it is PCIe x1 their photoshop artist just doesn't know what that looks like.

3 of these cards will make it 1.8T,  almost 1000x faster than a 2.1GH 3x5970 rig, is it really possible? Both 28nm tech, why kncminer consumes 1KW for 400GH while they can make it 4x more efficient???

BFL has been pretty consistently wrong about power consumption.  Every estimate of every product has been low and later revised to more realistic power consumption numbers.  Of course this has also resulted in numerous delays, incorrect parts, and redesigns too.

KNC simply says less than 1KW.   

Regarding power consumption, the actual 65nm consumes 3.1W/GH when operating at 950mV Core voltage (which also reduces speed). In the new chip, we've optimized and improved the design on one hand, on the other hand we're jumping down two nodes. The result of each node jump alone reduces power consumption between 40% to 60%, depending on the application and architecture.

The estimated power consumption report here has a significant error margin included.

I don't suppose anyone has details about how to compile the firmware on linux? Smiley

Atmel Studio exists on Linux as well.

The GetFrequency and SetFrequency never became operational. The reason is that we realized it's best to determine the frequency on startup. So I'm not sure if the command works at all or not.

Probably.

In my limited understanding of it so far, the firmware sets a target hashrate and then manages all cores wrt to error rate to maintain that. Sooooo... probably don't want to meddle too much for now and just try upping the target hashrate, and keep the cores cool so error rate minimised.

Yes the firmware performs diagnostics on start-up, determining chip frequency based on invalid/valid nonces generated by that chip.

Anyone can tell me:
1 why only 15 nonce like response is returned?
2 what was he tested? single chip? hash core?
3 why it take ~20s to have the power to return idle?


1) 15 nonce are returned because we run each engine the full range of 0 to 0xFFFFFFFF. They all find the same result, and we read all the engines when they're done.
2) 6 chips on board were tested with the same data. What was shown was the dump of 15 engines on one of the chips.
3) Because the processing range is not distributed among engines, so all the engines go from 0 to 0xFFFFFFFF.

Yes as they are both inductors.

Hi Everyone,

We've been very busy recently, unfortunately I couldn't catch up with the forums. There is a correction to be made: Chips are not and were not flawed. We decided to add certain clock buffers to improve noise-resistance and possibly increase frequency even further. The improve in noise resistance was our real goal (average frequency increase across a full wafer can be a bi-product). The decision was made to increase the near 100% chance of success even more. We'll keep you posted. If you had any questions, please let us know.

Regarding the chip being hardcopy or easypath or any other structured ASIC, please be advised that none of those chips come in small packages. They are all 480pin or above (BGA chips), not QFN. The reason behind it is that most industries going after hardcopy or easypth are the ones using the high IO count FPGA version of those chips (which are very expensive for a mass-produced product).

I hope this clarifies the situation.

Until then, you're publicly masturbating.
If they're seriously going to build high-dollar, high-mix, high-complexity (high-mix and high-complexity being the real difficulty) hardware on a MY-9, a semi-automatic (read: manual) solder paste printer and a 6 foot long reflow oven and then not even inspect the solder paste or placements and not x-ray the hidden joints, then I won't be masturbating for long...  I actually hope they prove me wrong and build great hardware, but it would be nearly impossible.

A 6 foot long oven can't (literally, impossible) have enough zones to form a proper reflow profile for a mixed technology/mixed thermal mass PCBA.  We use 14 zone reflow ovens that are over 30 feet long, and there are times we wish we had bigger ones.  Longer ovens with more zones allow for better profiles on boards that have mixed thermal-mass areas.  Run an Oven Mole though a 6 foot oven with the thermocouples attached to different parts of the circuit board and you'll see how incredibly uneven the heating will be in a short oven.

Do you know why contract electronic manufacturers exist?  Because most companies (yes, even ones that design really cool stuff) don't have the equipment or expertise to manufacture electronics.  Dealing with ESDs, MSDs, Reflow Profiles, Solder Paste Issues, Inspection, Re-work, etc, etc, etc, etc are not trivial....  Are they building with lead-free solder (for RoHS compliance)?  Do they have knowledge of how to reduce the risks of tin-whiskers if they are?  Are they building with water-soluble fluxed paste or no-clean?  Do they have the equipment to properly wash the boards if water-soluble is the answer?  Do they have an ionograph to spot test for ionic contamination?

Unless they can answer all of these questions, then bringing manufacturing in-house was a bad idea.

Enigma

I could be completely wrong here... but the above sounds similar to an auto mechanic insisting that his customer *needs* various things to make his car run property at 100%.  The mechanic is 100% correct, but a perfectly running car isn't what the customer is interested in.  Similarly, perfectly running products from BFL aren't really what I'm interested in.  If they have some downtime... OK.  If I have to finagle them around... fine.  In fact, I'd be happy if they ditched their cases and shipped their stuff open, like other people have shipped their FPGA's.

The fact of the matter is, the initial ASIC race will be won almost entirely by whomever is able to ship first, whether or not the products are 100% free of defects.

Of course I must add that this would be the case if you wish to keep your devices and not switch to other mining hardware. Otherwise, you may earn your hardwares
cost in a short time, but will be spending it to buy some other hardware, thus reducing your end profit.

This is getting complicated. So if you order a Mini Single you get put on the end of the Singles's queue?  Huh

Why not simplify and ship them all at once?  Tongue

Actually it is the idea for us. The community has put a great value on queue numbers. Our intention is to ship great number
of units all at once, and I believe we'll succeed in doing so after all the experience have we gained in previous generation of single
and MiniRig production.

They could kill tons of rumors just with that alone. (Please include any Exif Data and original file names!)

You must be new here, so let me answer this for you:  No it wouldn't.

Yes, I am new to this community.

Have you tried to actually do this before? From the way your talking to me, either you have done it and it failed (for some reason?) or you haven't and aren't willing to try.

Do you have a PR person? [a Professional]

I only know that one of your former products allegedly under performed and didn't live up to expectations. So I understand that angst in "these people". Beyond that, considering you have actually delivered products before to a market....why do you guys have such an incredibly bad reputation? Your company suffers from a very bad image seemingly beyond that bad product launch.

People are doubting that you guys are even a legitimate company. Why don't you hire someone to do the PR work to turn it around? Or at least provide the contradictory evidence that forces naysayers to back down?

I am going to be asking the exact same question of Avalon. I expect they will be forthcoming about their operation.

--------------------------

The people behind Avalon seem to have also delivered products to market as you have. They don't face anywhere near the same scrutiny and PR problems that your company does. Why is that? You might have a ton of orders but anytime anything [even tiny things] goes wrong it will just add to the bad PR.

Don't get mad, hire some professional, figure out what you can do to clean up that pervasive image of your company and solicit the help of forums Admins to intervene if someone says something which is verifiably false.

---------------------------

Full Disclosure: I am buying one of the Avalon Units. Originally, before I surfed this forum, I considered BFL the best option. Yet after reading through the forum I have decided to go with a company who users are less wary of. (A positive reputation)

Your company [BFL] looks like it has a lot more business and orders in its pipeline than any other. But after reading through the community your bad PR has "scared me away" from placing an order. If too many people are saying there is something wrong, then there is probably something to it. <---That is the pervasive impression I got.

Imagine that, I am going to buy from some company in CHINA...than feel confident in a company closer to home. That is the state of things from my corner.

If something [further] goes wrong in one of BFLs products what does that solidify in my mind?

To someone whom is seeing and reading that inundation of bad PR [whether it be true or actually very false and baseless], what does a lifetime of warranty and higher performance rating actually mean if most everyone is constantly hammering on about how many bad points BFL has? You would have to either own BFL hardware and by virtue of experience know of the reliability OR trust in what others have said.

It makes it feel more like "a gamble" with 1.3k (or equivalent bitcoins) than it really should be. I want to buy from your company what I need for mining. But damn, considering what has been the focus of things, it makes it feel much more risky than it actually probably is.

I am going to the company in China simply because they have a better reputation (or lack thereof). (even if it is baseless)

That is a very messed up situation!

Hello PuertoLibre,

I usually don't respond to unfriendly posts, but I need to address it every once in a while. As much as we respect BitcoinTalk fourm, for unknown reasons, there is a rumor-generator
about us in this forum. This machine is fully plugged and does not seem to stop. Every time we address an issue ( accusation, rumor etc ), it takes maybe 15 minutes until the next
rumor/conspiracy theory shows up. As a result we've given up paying attention to them. If this was to end at some point, we would've done our best to get to that point.

I personally believe that it's because we came up with a revolutionary product. It forced many GPU miners to convert, also created a risk for their business. Not all GPU miners were happy
about it and a number of them started to hate us. The other portion of the rumors appear to be arranged in some way, intended to attack Butterfly Labs. Speculation is also not uncommon,
as it's the nature of human and society to enjoy evaluating and examining both real and imaginary situations.

Nasser

Does the Single SC come with different firmware related with the room temperature and speed?

Actually I'm running a Single with a room temperature of 30C with Firmware - 832 MH/s never throttling.

I'm living in a very hot country and I wonder how the Single Sc I ordered will work with 30C and if there will be firmwares to adapt the SC to different temperatures.

Best,

ChiangYay


Hello Chiang,


The SC will not be sensitive to temperature. Of course, it is recommended to run electronic devices in cool area, as statistically
it prolongs their life-span.

The time I dedicate to our corporation has dramatically increased during the last 4 months, to about 7 hours during work days and a minimum of 25 hours during the weekend.


You seem to be saying that your position as CEO (or was it CTO?) of Butterfly Labs does not meet the US government's definition of employment.  Is this correct?

In France, it's best to be a French corporation employee. Anything other than that requires a lot of explanation and complicates your profile, especially as a foreign resident.

Not meaning to be difficult but do you mean 2.5mm/5.5mm plugs or have you changed the plug type to 5.0mm OD?  Thanks
