I couldn't get chainminer to work at all, all it does is freeze at

"M-Board version 2 detected
INIT: 256 chips detected"

At least bfgminer mines for a while.

   you sure not use BGFMINER and not working well with Hboards.

Does anyone know what this means? I'm having to restart bfgminer around every 5-10 minutes.

You'll have no margins for profit if chips are $25 ea.  That's $400 for the ASICs alone.

And I think it's generally expected when MGP and BFSB started selling H boards again they're going to have to price them at less than $300 per board or they'll generate very little interest.

Okay I want to brainstorm my ideas a little bit.
Here's what I am going to do. I am thinking of decoupling the voltage regulator from the PCB since it causes so much overheating issues. It will reduce board BOM and hopefully faster turnaround by PCB manufacturer.

I am planning to use multiples of this regulator since the output can be paralleled (~$55 e.a.)

http://www.intersil.com/en/tools/reference-designs/isl8225meval3z.html


a) Order chips ($25 ea on megabigpower.com)
b) Order decoupling capacitors for ASICs
c) Get PCB made and assembled by the PCB company (only solder ASIC + decoupling caps. No need to solder voltage regulator section)
d) Order Voltage regulators
e) Test assembled cards
f) Mine
g) If successful, sell to interested parties

The PCB layout is simple enough, someone here made an 8-chip h-board and shared the design. They had it manufactured by oshpark.com Easy enough to hand solder.

  Your errors overkill more than 50% and if you are not going to run 850W with 2 full kits.

+1

And being that the new H cards wont fit the older M boards totally sucks buttcheeks...

 If it's running, then;

cat /run/shm/.stat.log

 Looks like my second M-board no workie. Fuck. Troubleshooting continues...

Guys how much would it cost per board to manufacture and assemble the H-boards in quantity of 100? I am thinking of getting it done in the USA, since H-boards are not available and only chips are available

How I can take output log like this one ?

Not only did mine need that heat sink on the regulator on both sides but I found that if I covered the entire exposed part on the back they worked even better. I bought small heatsinks so they dont touch the traces.

I got my unit running with bfgminer, the only thing I could get chainminer to do was output

"M-Board version 2 detected
INIT: 256 chips detected"

Now I'm having issues with bfgminer outputting this, and the hashrate dropping.

We seem to be suffering from the same problem. I think it's an issue with the firmware not being installed correctly. However, I'm not sure how to fix it yet.

RE: heatsinks.. I'm positive its not the temperatures. I have a large box fan on them and the temp in the room is about 73 degrees... I have a 20k BTU A/C to help keep things cool.

guys please heatsink regulator, and at least the last 2 rows of chips.

I have a full rig populated and am trying to figure out how to get this thing mining. I can log into the ip address using my laptop via the bitfury admin page and set the pools address along with my username and password. However when I hit start mining, nothing happens. If I look at my screen hooked up to the raspberry pi, it asks for a login and password. I think the raspberry pi doesn't like my sidewinder x4 Microsoft keyboard has it constantly looks to have a stuck key. Not to mention when I try to type a password, nothing shows. It makes typing on this keyboard quite difficult. I'm thinking I might need to pick up a basic keyboard.

Anyone have a good how to setup link

 Thanks. Turns out I had a few problems;

 1) miner was not built.
 2) so far 1 bad hboard out of 32. Will get the second rig up-and-running later this evening.
 3) Here's the results of getting a rig to work :| Big-ass fan blowing on it... 850W power supply.

Got a long night of troubleshooting ahead

As suggested, I'm going to replace the H boards that aren't working on the rig that is half working to try to get it to the advertised 550+ Gh.

The one that's at 0 I'm still at a loss. I think it's a firmware issue. Are there any instructions on how to flash the SD cards with the images in the OP?

.stat.log doesn't exist because chainminer isn't working right, not the other way around. Try running chainminer directly like this, to see if it gives any explanation for not working:
