Hey, that's the same as BFL's box. Now Cablesaurus really needs to create proper 6-pin molex to barrel plug adapters. He could make a mint.

Help us! It's the Flying Spaghetti Monster!
Flying Spaghetti Monster gets 30TH/s @ 5W though...

Sorry you're right, I did not double check before I spoke

You're right. I for one would buy some. For large fpga farms using a 80 Plus Gold power supply (or better Platinum rated - but more expensive) is the way to go.

I really like your work, ngzhang.
Now I have to wait for eldentyrell to make progress to decide where my money goes next....

Wow ngzhang, that's pure geek heaven there (Icarus towers)!!!
On a different note, is anyone selling premade ATX power supply leads to power these boards? (ie with the correct 2.1 x 5.5 mm barrel connector). I saw a guide on ztex's site but it would be more convenient to buy some instead of spending hours making them.

wow, 13 port hubs? where did you get those?
And it would be really awesome if you could test the new MPBM on such a huge cluster
My board didn't arrive yet, so I'm not sure if the ported module even works at all right now.
(Seems to be stuck at customs - grrr.)

i must say...
Germany's customs is ****.
but , your MBPM is solid stable. like all Made in Germany stuff .
about the HUB:
here:
http://www.360buy.com/product/511117.html
very stable. with a 4A 5V adapter. about 24$/ea
Heh, calling that crappy garbled up display stable? You really need to try the new one
And I bet that hub is two cascaded 7 port hubs internally.

Not sure if you meant this, but a Hardware Error is simple - it's when the value returned was no good
(and cgminer keeps track of that also)
So what I meant was each time a bad share was returned you simply step the clock down as small as possible.
As I've mentioned before - I've had zero HW errors since I started mining with my 2 Icarus.
That's true, but ztex does more in this area. They don't just check difficulty 1 nonces, but rather the current nonce the FPGA is working on every couple of milliseconds. That way they can judge a lot better whether an invalid was just bad luck (some single event glitch) or whether that chip is being constantly overloaded.(and cgminer keeps track of that also)
So what I meant was each time a bad share was returned you simply step the clock down as small as possible.
As I've mentioned before - I've had zero HW errors since I started mining with my 2 Icarus.
Still zero HW errors - 7 days
It certainly wouldn't bother me in the least if it was 1 or 2 MHz below the failure point since I would hazard a guess that the life of the FPGA would not be very good if it was constantly at borderline failure.
(from what Energizer posted the current setting is obviously further below the limit than 1 or 2)
ngzhang: is that a difficult thing to consider? (Being able to adjust the MHz clock speed with a command?)
in my plan, a similar feature maybe add to next version of bitsteam: adjust frequency full-automatic.

for those of your that have the boards, do they come with iron rods so you can stack them?
