interesting project ...
did you have a working prototype ... ? to test heat, power drain and hashrate ...
I'm unsure but from my experience, already getting 2 GH from one chip drains a lot more power and generates a lot more heat, then what they are supposed to use in there normal 1.5 GH running mod.
Did you calculated with that? ... Just looking at my own boards ... 1.6 more power drain .... fully cooled the pcb temp. went from 41° to 49° ... having front and back fans with 1200 rpm .... and most of the chips are still running under 2 GH ...

Woohoo - got my starter kit out of billing-address limbo! Aaand... Hashrate 1hr 34665 Mh/s
At the pool!! 38W at the wall on 120V, which seems pretty good given how lightly I'm loading the PS (Corsair TX750). I have some tips to improve performance on the software side that I'm collecting as I roll them out here; I've got my pi's load average down to 0.10 and total CPU utilization at ~5% with only two shares rejected in the last hour. What's your noncerate at web-gui? |

we need to get some more data stuff into chainminer ...
.. but we will have to wait until bfsb commits there new chainminer version to github ...
.. one thing that is really important is the "putstat log" which shows the communication with the pools, we need it to be displayed in the web gui ... and also some long time data collection ...

Anybody knows what "speed->0" at the end of the .stat.log line actually mean?
2 AIfDSo 55 0.243 2.019 17 126 0 0 191 [0:1] 726 0 1 2 2 1 0 0 0 2 0 3 0 4 1 1 0 9 8 7 7 8 9 9 9 7 9 6 8 5 8 8 9 speed->0
10 AIfDSo 55 0.272 1.924 19 110 0 0 182 [0:9] 722 0 2 1 2 2 2 0 2 0 1 1 1 2 1 1 1 8 6 7 6 6 6 8 7 8 7 7 7 6 7 7 7 speed->0
#2 and #10 chips are not doing what they suppose to. I'm not sure if it is assembly or my configuration.
EDIT:
After a while the rates drop completely:
2 AiFDso 55 0.014 0.550 1 35 0 0 52 [0:1] 723 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 2 2 2 2 3 3 3 3 2 2 1 2 2 2 2 2
10 AiFDso 55 0.072 0.528 5 34 0 0 50 [0:9] 715 1 1 0 0 0 1 0 1 0 1 0 0 0 0 0 0 2 2 3 2 2 1 2 1 2 1 2 2 3 3 3 3
thats the tuning mod that was used for this cycle ... each cycle it will use a autotuning mod depending on the errors u got .... as long you got no errors it will speed up the clock +1 ... 13. Autoclock
- shut down = Chip will be shutdown and unavailable (Aifdso)
- speed->0 = If still more errors than correct nonces -> shut down
- speed up = If you have 0 errors
- speed down = If you have >5 errors clock down |

That would help, wouldn't it :-) My public address is 16JZWC433XRxjWwR7X65uxRVFdLTmoPr4t (same one I sent payment from) (Will you be sending info to Shareholders regularly via BitMessage, Google Docs or email ?) Until now i informed with PM ... as we are now in the mining process ... I will schedule more often notifications ... also for payouts ... like tomorrov.... Probably I gona try gather the eMail adresse ... |

i got those pictures sent from a user ... to guide through the process of the pencil mod .... ***be aware that you loose warranty of the h-board in doing this ... and you can brick your board!!!***details:- temp +10-15° - 1.6 times higher electricity needed - up to 50% increased hashrate Step 1: unplug your h-board ... and locate the R02F Resistor  Step 2: use ur multimeter on the resistor and verify that it shows 1.3k Ohm  Step 3: use a HB (medium grade) pencil ( http://en.wikipedia.org/wiki/Pencil) and rub 2-3 times  Step 4: use ur multimeter on the resistor and check how much it was lowered in resistance ...as long as your higher then 1.2k restart step 3 & step 4 ... goal resistance is 1.1k - 1.2k, if you get under 1.1k just swip a little away with your finger ... Step 5: plug in again and start  have fun ... |

Wie kann der Miner mit 16 Karte 400Ghs schaffen wenn jetzt 2 Karten 40Ghs machen, nur so aus Interesse, ist das Feintunning ?
die 400 GH Kits wurden mit einem zusätzlichen M-Board und 4-5 H-Boards versendet .... um die 400 GH zu erreichen ... |

a damn i have now a pencil in hand ...
... isn't the freestyle way just to .. rub 2 times over the R02F
... and go?

I was just about to order, but yesterday Punin answered in BFSB thread.
We are going to offer new C-scape Shash board.
I've got some sample chips from Punin and I'll have working prototype next week.
All the pricing is ready expect the chip price.
Thank you for the efforts Zefir
can you link the post from punin ... in BFSB thread ... |
