Xian, turn down the voltage by turning the trimpots to the left on those cards

 I'll try that. Thanks !

I was seeming to get good hashrates relatively (like ~520 - 550 GH/s)   Just got home see that my rate was around 385 with two dead cards (currently I have my miner restarting once an hour in case that happens...look like it didnt seem to help this last go round   )

to restart my miner, in ssh  type

Code:

 crontab -e
*/60 * * * * sudo /opt/bitfury/start-miner.sh

No offense, but this kit is wierd, awkward, lacking, whatever you want to call it.  So far I've spent a lot of time:

Taking all cards out and slowly adding them and running it for 30 minutes to see how high they go and to attempt to set them to around 30 GH.  I tuned the majority of them to stay on, here is my up to the minutes stats from CAT:

Not terrible but by no means any good by what Dave quoted earlier.  (might have increased slightly because my main window shows 475 GH/s)

Good job to the dumbass misguided helper who chose the smaller than atomic particle Potentiometers (something just a little bit bigger that wouldve been easier to catch with a screwdriver would have made all the difference to me) that are too small for anything.  Smallest screwdriver I could find in frys barely seems to catch them most of the time.  Extremely frustrating when trying to undervolt the cards for the sake of keeping them on.  

I have a SHIT-TON  of heat sinks - The only thing I could think to do more now is to buy up another 32 tiny heat sinks to put onto the top and the back of the voltage regulator.

Get yourself a phone repair kit, the ones that came with my replacement screen fit perfectly.

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

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.

Lets say I do it without any profit margins, just for the community at first.

BTW can I use this to hand solder the ASICs without much problems? http://www.cmlsupply.com/model-850-esd-safe-hot-air-rework-station.html?gclid=COTelKSe3roCFa1AMgod8VMAaw

   by time you got pcb and chip price for Jan. 2014 like 5.00 per chip.

 Something definitely seems amiss with these kits.

 I received 32 H-Cards, and 2 M-Boards. 1 M-Board is DOA and have filled an RMA request with MBP.

 I've swapped out several H-Cards in slots that had their hash-rate go from full to zero, and even new sealed H-Cards start slowing down and approach 0 GHs in the same slots.
 
 Best I can tell, at least 2 H-Cards are completely DOA, and having sad-times getting a full M-Board hashing steady above 500.

 Fuck

 Will let it run for a few hours and see how things look a bit later...

EDIT: Well, that went to zero quickly... Fuck. Eg: Swapped slot 1 and 2 for new H-Cards...

Xian, it's very possible that your cards aren't overheating but are actually shaking side to side and losing connectivity.  That's what happened to me, anyways.  These new 1x PCI-E edge connectors are horrible.  I'll post a picture of what I ended up doing to fix it.

Looks pretty similar to the one I have, I use it regularly to solder 0402s

Ah ha!  Now I know why random cards have dropped out.  It's always happened when I've moved a fan or slightly adjusted the position of the M board, etc.

Yeah.  I couldn't figure out why my rig did worse in the garage with a loud box fan blasting on it with near-freezing air temperatures (as opposed to inside the house with a less obnoxious fan setting).  I finally narrowed it down to the boards wiggling around slightly.  Sometimes I could get them in the right position and they'd run for hours and then randomly crap out.  Here was my fix (just cut slits with a miter saw):

Ah ha!  Now I know why random cards have dropped out.  It's always happened when I've moved a fan or slightly adjusted the position of the M board, etc.

Sometimes I could get them in the right position and they'd run for hours and then randomly crap out.  Here was my fix (just cut slits with a miter saw):
https://i.imgur.com/SfpNAa2l.jpg

 That is madness.

 I've removed the fans that were blowing on them, causing any movement, and hooked up fans onto the headers, and have fans resting on top of the H-Cards, blowing down and giving them more support... in theory...

 Cards in the same few slots still creeping towards 0.

I laid mine on its side, with a tower fan on its side blowing from the "top"

[goxed]

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

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.

Lets say I do it without any profit margins, just for the community at first.

BTW can I use this to hand solder the ASICs without much problems? http://www.cmlsupply.com/model-850-esd-safe-hot-air-rework-station.html?gclid=COTelKSe3roCFa1AMgod8VMAaw

Looks pretty similar to the one I have, I use it regularly to solder 0402s

So do you think it will be fine for soldering the Bitfury chips? Thanks

They're either overheating or losing connectivity (or a combination of both).  It's possible that you got a bad h-card somewhere, but it's damn near impossible that you have SIX bad boards.  Keep in mind that if a board loses connectivity, it'll generally take out additional boards that are next in the chain.

If you want to help rule out the overheating, tune all of the chip clocks to 52 and see if they stay hashing (or stay hashing longer).  If you have a voltmeter, it's easy to see if they overheat.  The voltage will gradually creep up as the VRM heats up, and eventually it hits a point where the voltage moves up *quickly* and then nosedives when it shuts off.

What am I doing wrong here?

I downloaded putty.exe so I could ssh into my setup
Then on my laptop I entered login (pi) and the password (raspberry)

I typed (I have almost no idea what this does, found it on Bitfury Miner Support)
cd /opt/bitfury/chainminer
sudo make clean
sudo make
sudo killall screen
sudo /etc/rc.local

I typed the raspberry pi IP into my url and changed the default mining pool, along with my username and password. I hit start mining and the power goes up to 650 watts or so for a minute and then the system shuts down and it is not a cooling or power issue.

How do I get this to mine?
