BFL SC Singles running smoothly. ~59 GH/s each at 278 watts each

[twmz]

Although it took 1 year to get them, I am happy to have them in my hands and mining...



The "fast" worker includes a 5.5 GH/s jalapeno as well:


Power usage: 440 watts on that circuit before plugging in the two singles, 996 watts after = 556 watts for the pair = 278 watts each on average:

Great!

coool

Nice to start seeing more of these in the wild.

I see you had some first day orders. They need to get through 11 more order days til they get to mine. I'm a little jelly

[cdog]

Cool. Congrats. I wonder how many total Singles have shipped, and what BFL's per day output is at this point?

[davecoin]

What a happy little mining family you have there 

[erk]

278watts per unit is good for that hash rate, considering that some of it will be the PSU and several fans.

Great efficiency!!

4.71w/G. So the chips are made of 110nm?

4.71W/GH/s is not what the chips consume. Think about the error in your calculation.


For starters a 110nm Avalon at 66GH/s consumes over 600watts, the BFL is less than half that.

My power numbers are taken from the wall and so do include the inefficiencies/overhead of the ATX power supply.  I also think I added one additional table fan when I hooked these up, to the power draw from that fan may also be included in these numbers.  When I get back home this weekend, I'll take some more careful measurements to isolate the power usage of just the SC Singles + power supply (which includes their chips, their mainboard, their fans, the ATX power supply, and the power supply's fan).

Did you get power brick or just use ATX PCI-E power connector?

ATX power connectors are the only option at this point.  BFL does not have the power bricks yet, and so if you want a power brick, you have to volunteer to have your shipment delayed (which would be stupid).  I happened to have a good ATX power supply left over from my GPU mining rig (which has now been retired), so it wasn't a problem for me.  My guess is that my ATX power supply is more efficient than the power brick that they will eventually have anyway (and it is UL tested and certified).

From what mining platform or monitoring tool are you pulling these images?
I assume the top one is a pool? But the bottom one? TIA

The top one is btcguild.  The bottom one is not a mining thing.  I have do-it-your-self internet-enabled power/energy monitoring in my home and this is one of the dashboards for that data.

Major thumbs up!!

thank you for this TWMZ. I have been searching for some real power numbers for the singles.

now to extrapolate to a little single (if these ever get shipped) I would assume little more than half, probably 150W each is a generous estimate.

I'm guessing you run each single from a dedicated PCIe cable. What are the connectors like on the ASIC end? is it 2*6 pin connectors? or 1*8 and 1*6 -- or 2*8?

Do you expect one would be able to run 2 little singles from one PCIe cable?

Each single has a two 6 pin PCIe sockets.  So I have 4 cables coming out of my PSU.  Two cables go to each single.  The particular PSU I have is modular, so I get to choose exactly what cables I want coming out of it.  In other words, I don't have a mess of HDD cables or other unused power cables, etc.

I have no information at all on the little singles.  They are half as fast roughly, so you'd think they would use half the power requirements and therefore might have half the connectors, but again, that is entirely conjecture.

You better mine the s**t out of them. Look what's coming: http://scienceblog.com/64278/large-scale-quantum-chip-validated/
