Butterfly Labs just sent me an update e-mail!

This is what I see when log into the web site:

Important Order Information
Dear Butterfly Labs Customer,

Thank you for your patience. Production and shipping of Butterfly Labs Bitforce SC (ASIC) products has begun. Before we proceed with production on your order, there are specification changes and we need your acceptance of these changes before we proceed.

Power consumption on all SC products is higher than we expected which has resulted in changes to the product packaging.

    60 GH/s 'Single' units are being shipped in a rectangular case about double the size of the cube.

    All customers will be shipped the GH/s hashing power they originally ordered.

    By clicking the accept button below, you agree to accept product specification changes and pre-order terms as specified on product pages.

    If you do not agree to accept these terms, click the Refund to process your order refund now.

Have they even said where to mail the fpga's yet? I waited 3 weeks to get a reply about what the address is, all they gave me was a link to their forums. Worthless customer support.

What is now with the Delivery Estimate ? For JUNE and JULE last Year ? After Confirm the new Terms ?

Mother of god! How is this little thing supposed to dissipate 300 Watt of heat?

At least something interesting came from that email.  New pic of single--->>

You all know how big 7970 heatsinks are - and they are designed to handle "only" 250 Watt.

Mother of god! How is this little thing supposed to dissipate 300 Watt of heat?

From the pic, you extrapolated :
#1 It uses 300w
#2 Heat dissipation properties of the heatsinks

HOLY SHIT someone give sherlock here a fuckin job at the fbi. We shoulda deployed to you look for bin laden mr. Colombo.

It's not extrapolation, just simple facts and some math.
A 5GH/s Jala is ~30 watts (measured with a Kill-A-Watt).
The box contains 2x25GH/s little singles (obviously).
So 50GH/s = 300 watts

So 50GH/s = 300 watts

Look up extrapolation in the dictionary. You are estimating based one a jalapeno, which used to be the little single board. These are different boards going in. Could be more power, could be less. But to say 300 as a firm number is an extrapolation.

Please don't feed the trolls.

You don't know how many ASICs are on each board, or the clocks that they are running at, you are just assuming it's similar and extrapolating.

You say that likes its a bad thing...  This kind of extrapolation is done all the time.  Its a first order approximation.

Not to mention that a tripple-slot board is about half the height of a classic coffee-mug.

Why should that be mentioned? Missing your jist my man.

It means that the heatsinks at the singles are probably more or less twice as big as they might look like.

My guess is that they are both about the same size as the heatsink of my 9550's that draw 200W

[minternj]

And what are the implications of that? Or are you just making an observation?

[ModusPwnd]

The implication is obvious.  Those heat sinks may in fact be able to dissipate 300W.

It was a reference to the post from  Frizz23 "Mother of god! How is this little thing supposed to dissipate 300 Watt of heat?" - and your reply to that.

I was merely pointing out that his extrapolation about the heatsinks, who were probably based on direct comparison of the two pictures that are scaled differently, making the card look almost as big as the single.
IOW- There is really no reason to believe that the heatsinks are not up to the job.

Ahh.. The joy of using my second language.

you're assuming that there's a linear extrapolation here... interesting...

[Red_Evil]

Haha and now ?
Looks like ?

So both will be manufactured, equally, slowly.

The mining hardware doesn't directly connect to the electrical supply, the power pack does, so it is the item that has to be certified, and you could simple go to the shop an buy one locally that is certified if necessary for insurance or whatever.

My laptop (Toshiba, made in China) doesn't connect directly to the power supply, either, but it still has the relevant Australian certification mark (the power supply - which obviously ships to more countries - has about 15 certification marks on it for various countries).  

Even my solar powered Christmas lights and my aquarium pump which draws a whole 7 watts have the power specifications stamped on them.  My digital camera and it's charger and my mobile phone and its charger also have compliance marks on them.  In fact, I can't find a single thing in my house which connects to the electrical supply even indirectly which doesn't have the power specifications stamped on it - which makes me very inclined to believe that it's a requirement of the Australian standard.

Your laptop puts off intentional and unintentional radiation. It has a screen, and it has a wireless card. Both of which make it a COMPLETELY different animal from a mere peripheral, which the Jalapeno is...

The extrapolation is a valid approximation.

If they were using a significantly different board between the the microsingle 5Gh/s unit and the 25Gh/s unit, then all bets would be off...  But BFL themselves said that they are using the same single sc board for the 5, 25 and 50 models.

Soooo... ~300 watts is accurate for the 60, and I would surmise that BFL would do some kind of testing (once they get the 25 and 50 running) to ascertain if they need a new case and heatsink/fan arrangement is adequate.  If it isn't, they will redesign it until it is adequate.  One thing about BFL seems certain that they aren't going to ship a product that isn't perfect.

Unfortunately perfect takes time.... lots of time.
