[ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***

[xstr8guy]

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.

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.

That's happened to me with chainminer before. I just rebooted the rPi or restarted chainminer until it worked. Also, be patient, sometimes it takes a minute or two to get past that point.

[chamber32]

OK, I can manually run chainminer with this:

Code:

sudo killall -q miner ; cd /run/shm ; sudo /opt/bitfury/chainminer/miner

But all I get is "INIT: 64 chips detected" (after I compiled)

What's next?

EDIT:  I got it to work by deleting existing chainminer & cloning & making a new copy

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

 Swapped out the PSU for a Corsair AX1200.

 Chainminer runs fine for a little bit, then a few boards start dropping down to 0GH/s.

 BFGMiner is a fail spamming all sorts of nastiness.

 *sigh* Very frustrating

 These guys are finicky Have some big-ass fans keeping them cool, so I can't imagine they are overheating Room is 76C.

 Below you can see the few boards that are starting to reach 0GH after starting strong.

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

[mb300sd]

BFGMiner has been running for 35 minutes now, might have been a heat issue. Its cold outside now and I leave the window in the server room open.

The 1 dead H-board is still dead tho. I might try immersion cooling after it gets RMA'd

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.

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.

[Xian01]

 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...
