Topic: ACTUAL Butterfly Labs PCB pics! - page 10. (Read 40283 times)
any live demonstrations of the chip working or mining at this time?
I am happy and alot more confident now that we are gonna start getting our orders in the next couple weeks and it hasn't all just been a massive scam.
It's interesting times ahead for sure, cannot wait any longer now. All this information makes me want to have my singles now

The theoretical max performance of a fully populated card is 128 GH/s. It's highly unlikely that we'll ever get close to that peak performance. Nevertheless, there's quite a bit of margin left above the 60 GH/s mark... some of which is being enjoyed in the Mini Rig configuration of the card.
Hmm - would be good to see a Clock command in the firmware spec.( Though last time I mentioned that quite a while ago, someone wasn't too happy about my wording ... )
I've just been playing with clock adjustments on the MMQ I got - was actually quite interesting in my opinion
Of course being able to adjust the Clock also requires some well defined specifications of the device limitations and performance and being able to accurately measure temperature
Though when devices hash 100x faster than they do now, it means dealing with the limitations properly is extremely important.
Anyway - we'll find out when the info comes out for each of the ASIC's what options there are with this sort of thing ...
[Speculation]
If we go by what we do know....then a mini-rig has 192 chips (24 fully populated boards).
Each Chip runs at 7.8125Gh/s.
Consuming just under 8 watts per chip.
7.8125 X 8 = 62.5 Gh/s per module.
Each boards draws about 62.5 watts X 24 boards = 1500 watts
Not including fans and a few other devices with marginal draw. (hence their power supply is 1650watt if I recall correctly.
Edit: Assuming a mini-rig board is about 100mm between boards and is distributed at even distances of 3 x 4 into 2 separate stacks. It should occupy somewhere around 1' depth x 2 feet height and about 8 inches width.
Or roughly the size of a full tower computer case. (well minus the radiator if they use the water cooling techniques.)

So the actual max is not 1Ghz but closer to 1.1Ghz.
With a max draw per chip of about 16 watts.

WOW So maybe faster firmware,like the FPGA single,later on
I would hope it's just something as simple as adjusting the clock rate, like configuring a GPU.

1 board per device, with the exception of the Minirig, which has 24.
24boards x 60GHs/board = 1440GH/s = 1.44TH/s. Maybe they OC them a little bit to get to 1.5TH/s, or maybe the Singles run slightly higher than 60GH/s? 62.5GH/s would give them 1.5TH/s with 24 boards.

.Do my eyes decieve me, but does ASIC chip 4 (1st on second row) look like its bulged out?
POP!
Could be camera angle.. Could be a Photoshop job to remove something.. most likely, it's damage from someone not following MSD procedures. Looks like typical popcorn damage.
Or it could be that it was an early sample where someone stuck an oscilloscope probe where they shouldn't have and shorted something out. Not that I have any experience with doing that...
BFL, I will say one thing, the layout is pretty elegant. Nice job.
Actually my mistake, the bulge pic was rotated.
1 board per device, with the exception of the Minirig, which has 24.
It looks like all of the ASIC products will be built around the same board, populated differently. This raises a question: since the ASIC in the Jalapeño is significantly underclocked to keep power consumption down, would it be feasible to add in some of the power-supply components of the other models and a heatsink to get the Jalapeño running at the full 7.5 GH/s that the chip can deliver?
If I had to take a stab at this configuration, I would say that a Single SC is actually comprised of 2 of those fully populated boards (each with 8 ASICs). Note the little off-white connectors on the board marked "Chain In" and Chain Out" which alludes to daisy chaining these little suckers (maybe just for the rig, but maybe not).
That would put a Little Single with 8 ASICs, which would be 3.75 GH/s per an ASIC. This is around what the Jalapeño is specced to run. They may be able to overclock it because they have less overall heat to dissipate with only 1 ASIC.
Bulged? Looks like they've been 'shopped to remove any manufacturer markings.
There is another photo with the device pictured on another angle. It is the same chip with the same bulge.
We should call it....BulgeGate!
A revolutionary 3D processor from BFL. [/joke/]
---------------------
Hopefully it is a manufacturing defect they actually noticed. Ever seen what happens when a heat-sink doesn't make good contact with the chips...totally fried. I hope they do visual inspections before final assembly.

Thats what I was thinking when I first say the pics, the smudged out the markings on the chips.

Nice screenshots, now we need a working prototype

Hardware hacks are bound to show up soon after devices are delivered 
It will just depends on the network difficulty if it will be worth the time and effort to try to OC the coffee warmer.
