Thanks for the heads up, I'll give it a try.
November 12, 2013, 01:35:39 AM
Spent about 12 hours tinkering with it, but I think I finally got mine working... no clue whats gonna happen tomorrow when it warms up tho.
You are luckier than I, enjoy it sir.
After spending several hours trying random things suggested all over, I've still had no luck. One rig starts off good at about 450 Gh, but slowly goes down to 250-350 Gh. I have to hit start/stop every 5 minutes to keep it above 400 Gh.
The other one can't even pull 0 Gh. I'm thinking it's possibly a bad M board, or something is wrong with the firmware. There are others with this problem.. so I'm glad knowing I'm not alone. It sucks having an $8,000 bitcoin mining rig and it can't even do 0.1 Gh. I'm gonna keep messing around with it, but at this point I'm at a loss as to what to do.
Mine did the exact same thing. Your chainminer is probably freezing on startup, i couldn't get it to do a single hash. SSH in and use bfgminer instead, you just won't be able to use the web interface.

I have to hit start/stop every 5 minutes to keep it above 400 Gh. I am now switching out H cards in different slots to try and see if I can come up with a card configuration that will run more stable. I read putting bad cards in the last slot of every bank helps.

I am finding this whole experience with bitfury very annoying.
Glad to see that I am not alone.
I have only seen the H-cards run for a few minutes before the overheating starts.
I don't want to waste time with adding heatsinks, or fine tuning voltage. I just want these to hash.
I really think that pushing the default config for the h-cards to the bleeding edge of performance was a bad idea.

reading the last few pages makes me feel not so bad.
I'm happy for you, HashFast shill.
no, more from the standpoint that i have been having alot of trouble with my BF's as well.

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.
No kidding
Having a helluva time with the smallest screwdriver I could find from Fry's...Not even sure if I'm getting any movement.
Get yourself a phone repair kit, the ones that came with my replacement screen fit perfectly.
Or an eyeglass repair kit.
I had an eyeglass repair kit and it was too big! Hence the trip to Frys.

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):

Keep in mind that this was manually tuned and I have access to unlimited amounts of very cold air.
That's beautiful, what type of tuning did you do to get the ones over 40 like that?
I went ahead and made myself a stablizer to attempt the same thing. I think because I had the 120mm fans on top sitting in a way to keep them from doing the shaking was why I was getting stable numbers.
Also, what is the measurement of the spacing you used on your board there? I think I will build the same thing. I used to foam which is working well but Id like to make it better.

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
Yeah, should be fine. Although you might want to get a stencil for at least a QFN if not the whole board. http://oshstencils.com are really cheap.

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?

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.
Looking for some guidance from Dave and crew, 'cause something isn't right with this batch

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.

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...

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...
