Software bug: changing cgminer configuration claims to work at runtime, but does not. Thus, changing pool settings requires a reboot.
Chip's power consumption is <6.6W/Ghs
ATX power loses(82%), DC/DC power loses(87%), Fan(5~20w), etc…
So…
ATX power loses(82%), DC/DC power loses(87%), Fan(5~20w), etc…
So…
650W * 0.82 * 0.87 - 20W = 443W, About right.
so an equivalent bfl number would be something like:
60w / .87 / .82 + 2W (fan) + 5W (host) = 91 W (host can be discounted for many since it can run several units)
or "bfl's worst case" 60W * 1.2 = 72W ===> 72w / .87 / .82 + 2W (fan) + 5W (host) = ~108W

Disgusting coming from a guy claiming to be CEO of a company holding millions of community coin and dollars.
I don't think he's the CEO, nor has he ever claimed to be. Are you surprised?
Paging Jgarzik. Party of one. Jgarzik, party of 1! Your seat at the ASIC table is ready. JGarzik, party of 1!
I think this is one dinner you'll be happy to eat alone.

I'm sure the fair and balanced mods will be all over this one and warn him for trolling. Disgusting coming from a guy claiming to be CEO of a company holding millions of community coin and dollars. And also more importantly taking away from the real discussion that is the dawn of the ASIC age of bitcoin mining, something Jeff Garzik is sure to be instrumental in the ushering in process, which he has done like a boss:
Trolling? I don't see his comment that way at all. It sounded like a light hearted jab at the "users" part of the thread title

Here is a general thread for owners of Avalon ASICs.
This is the review I posted: http://garzikrants.blogspot.com/2013/01/avalon-asic-miner-review.html
The restart issues mentioned appear to be have subsided (knock on wood) since I laid the unit down, and adjusted some air flow issues in my office.

Damn fine work Jeff. [and separately, bitcoin foundation] This important technology is best put first in the hands of the good guys.
Do not let any drama derail your important work as the Avalon ASICs come online all over the world, further securing the network as long as too many of them don't work band together with a pool of FPGAs and work for evil.
The host in this case is a OpenWRT board pulling what 10W? Ok so 620W vs 610. Claiming 400W on your site is disingenous. Sure you have DC to DC losses so does anyone but that is part of the power load. AMD doesn't quote the power consumption of the raw chip when selling an entire graphics cards. They quote the card power usage which includes GPU, RAM, VRMS, fans, and any associated control circuitry.
Your system doesn't use 400W. Don't advertise that it uses 400W. It uses ~600W. Claiming anything less and then saying "oh it needs a host" when you know the host board is pulling a tiny fraction of that is just plain dishonest. Period. 620W vs 400W is a 55% increase. That is significant. Rise above your competitors and start acting like a real company. You know a real one which wouldn't pull a stunt like this because they would be facing a class action lawsuit for blatant misreprenstation of a material fact.

However, it is fair to provide the base power consumption, because that potentially provides a better apples-to-apples comparison with other competitors.
IMO module and whole-unit power consumption figures would be the ones to publish.
Any system needs to pay these extra power, including BFL.
Can we have honestly from one builder ONCE? You guys were doing so good up to this point.
That is pure and utter crap and you know it to.

I'd like to point out that the power usage for this unit is economically irrelevant, and not really necessary for discussion.
The statistic that matters most is time -- Avalon released first, so they win. That's really all there is to it.

Maybe for batch #1 which can take advantage of a lack of competition, but batch #2, batch #3, upgrade modules? Power matters in the long run.
Purchase price: $1500
620W for 1 year @ $0.10 per kWh = $543
620W for 2 year @ $0.10 per kWh = $1357
620W for 1 year @ $0.10 per kWh = $1086
620W for 2 year @ $0.25 per kWh = $2715
So depending on the economical lifespan of the miner and the power costs we are talking from 26% to 65% of "total cost of ownership" being electrical costs. A 55% increase over quoted power consumption is significant.
PSU issues can be fixed if the end-user feels like paying for a better PSU
140usd. plug in a SeaSonic 750 forthe win
The miner is currently running on an already loaded residential house power circuit, while sharing a Back UPS ES 550 with another desktop machine.
If I were you, I would plug it right into the grid, or into a UPS that outputs true sine wave AC.
An APC Back UPS ES outputs nasty noisy square wave AC that isn't real good for things. I wouldn't run a computer on one myself, much less a rare and expensive ASIC miner.
I also would not trust the power measurement taken by a kill-a-watt with it plugged in through that UPS.
agreed.
also, i think its fair to see that the PSU efficiency isnt a necessary factor in the announced power use. When you say a 7970 draws 400w, do you account for the PSU efficiency? its a fairly uncommon testing value.
should be 3*[power per board]+[control board]+[fan power] to identify the system draw. PSU issues can be fixed if the end-user feels like paying for a better PSU
Somewhat OT but directed at comments above:
I will have an r-pi B very soon.
The person supplying it has been having USB testing done without the USB problems being reported - due to his work on it.
https://bitcointalksearch.org/topic/m.1489596
My current cgminer BFL USB code (the USB code is not in the Avalon) uses only a few CPU seconds per hour on my 3.6GHz desktop with 1 BFL FPGA, Stratum mining at 8 difficulty on OzCoin
This code isn't in the Avalon - so no idea how well they scale or how much CPU they a;ready use.
(as we all know - they didn't deal with ckolivas or myself doing the code and thus the Avalon code doesn't include the new upcoming features of cgminer that anyone can already get and use - it's open source and in my git)
5.5 hours runtime (top output) yeah it really isn't using much RAM there either:
4080 root 20 0 1498m 4220 2628 S 0.3 0.0 0:13.81 cgminer-2104n

thanks for clearing that up ngzhang.
Makes sense as it's a stand alone unit. When quoting BFL's numbers, no one includes the PC it's hooked up to either.

No, I think it's nothing to do with the host PC.
To power the chips, we must convert 220vAC to 1.2v DC. And we must shift all heat out. This process cause power loses.
Any system needs to pay these extra power, including BFL.
So please do not use an " announced " chip power consumption number to compare with a full system power consumption number, it's meaning less.
Do you know the power draw per unit @ 1.2v DC?
Thanks!
Did I tell you to shut up?
BFL can plug into a OpenWRT device LIKE one in AVALON. Even an Android phone would work.
Your question is does Raspberry Pi gonna have enough bandwidth as a host? Fck yes, it also shows you know crap about this.

Avalon engineered the OpenWRT solution to work effectively.
I don't know what they had to do to make that happen, but I know that you can get away with using a low computer power single purpose device if well engineered to the application.
Everyone in this thread seems to be suggesting the end consumer should slap some 5W toy device called a "Raspberry Pi" into their BFL miner. My experience tells me this is not a real solution.
What operating system and mining software should they install on it? What optimizations should they perform on the OS build to ensure the bitcoin miner is not interrupted by other processes?
If BFL isn't going to provide a mining controller, then most users will end up using a real computer, not a "Raspberry Pi." You should be more realistic.
ngzhang, what power supply will all of the V2 units ship with, and will it be capable of actually running 6 modules?

BFL themselves have said they'll support Android as a host.Guess what processor is in your Android phone? An ARM. Guess what processor is in the Raspberry Pi? An ARM.

Perhaps you should read the BFL forums more. A lot of them are planning on using a Raspberry Pi - and why not, they only cost USD 25-35.
These toy devices are a PITA in my experience. I wish them good luck if they do not have experience with these products. Hopefully they are easier to use than a Beagleboard or similar.
And it is starting to 'warm up', it's going to need 3 fans in there.

1. What is your ambient room temp.
2. Temp on heat-sink (shielded from air flow)
