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.



So the actual max is not 1Ghz but closer to 1.1Ghz.

With a max draw per chip of about 16 watts.

[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.)

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 ...

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.

Next couple weeks huh?  I hope you're right, but I fear you're way off, especially with the new announcement of shipping dates being November/December.

I wonder what the ARM place holder is for ? how could an ARM chip benefit the board ?

Add a network jack and some ram and you'd be able to have a low power standalone miner --- maybe?

That would work if the board had place holders for those additional things, but it does not so it would need a board re-design, which makes it pointless placing an ARM holder on the current board.

Maybe one board, the one with ARM MCU soldered, will act as main controller or super controller in mining rig with all the other boards daisy chained.

Quote from: BFL_Josh
Henrietta the flying pig makes a cameo along with a Jalapeno, a Minirig SC card and a bare board (waiting on chips!).
Quote from: bobitza
The jala will be the board with no capacitors and just 1 chip; the little will be the board with 4 chips and the single will be the board with 8 chips?
Quote from: BFL_Josh
Yep, pretty much.

So do you suppose they intend to use that reflow oven to add the needed chips to those boards?
