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

[ericdc30]

  Hi guys I have this card that keeps going to 0GH/s. I already used the last slot for a card with high miso error count. Any idea what procedure I should be following to get my rig working at 100% reliably?

[Doff]

Got my rigs in, and can't get chainminer connected to ghash.io at all Trying to build BFGMiner...

Poop.

EDIT: Fuck my ass. BFGMiner only picks up 4 of 16 boards on the first rig I'm trying to bring up... it's going to be a long night...

Odd I am using ghash.io with no issues. Make sure to cool it enough, but don't over-cool it! Haha.  The heatsinks on the back of the regulator help I have found as well.

[Doff]

I've written a cgminer driver (it's in the current cgminer 3.8.0/3.8.1) for the BlackArrow Bitfury V1 boards.
I've no idea if that is the same as a standard Bitfury board - I never had one and the twits would never sell me one either.
... maybe I should have put in the copyright header that Punin and Buzzdave aren't allowed to use the driver

Anyway, as I posted about it the other day:

For anyone who has a V1 BlackArrow Bitfury board - the latest cgminer 3.8.1 (3.8.0 also) has the RPi source for a driver now - consider it an early release since there are certain improvements I'll make to it that I've already sorted out what to do - in future versions - but it already runs with great performance.

The configure option is --enable-bab

It runs at 39.9GH/s valid shares with a bit under 10% HW errors above the 39.9GH/s on a standard board
i.e. if you were to also count bad nonces returned (which I prefer not to but I will mention in case anyone wishes to compare that number) it's returning 44GH/s of good+bad nonces.

I've run it with a single board on Raspbian to write and test it - it's based on the V1 initialisation of a single board.
I based the I/O code on the chainminer GPIO/SPI code as should be obvious for anyone who looks at my driver-bab.c and chainminer (as I also mention that at the top of driver-bab.c)

It's a bit CPU hungry so soon I'll be spending more effort on reducing that - 20% CPU with a single board - I've only tested with a single board.

It also doesn't tune the chip at all - so there is also assured performance improvement there - it runs at default settings at the moment.
That's the next effort I'll expend on the driver.

If anyone has a standard V1 BitFury board I'd also be curious to know if it works with them.

Id love to see this running on a V3 rig, I miss having fail-over. Its Cainsmore all over again for me.

 Did you have to preface the ghash.io url with "stratum+tcp://nl1.ghash.io" in Chainminer ?

 Guess the .stat.log not being where it is might explain something wrong with why Chainminer isn't starting up....

No, and make sure you use a password it doesn't like the blank one.

I just have nl1.ghash.io in all 3 boxes.

You need to turn the voltage down, scroll back a few pages to see how to adjust the trimpots

If its one of the new m-boards, the cards are divided into groups of 4.

[mb300sd]

I have 1 bad H-card what will not hash at all... Waiting on RMA, how long does it usually take?

[Xian01]

If its one of the new m-boards, the cards are divided into groups of 4.

 Oh, I see, so 16 boards should appear as 4 miners to BFGMiner ?

[CoinHoarder]

Hrm. This is not exactly how I envisioned this going. This is very frustrating.. my Avalons and KNCminers I was able to setup and get hashing within minutes. Add the assembly time of a full rig, plus the fact they're both not working....

I got two full rigs today. One is running at 225 Gh and the other is running at 0 Gh.

Code:

Rig 1:
Bank 1
1: 33.415GH/s
2: 33.443GH/s
3: 20.702GH/s
4: 21.79GH/s
Bank 2

6: 0GH/s
7: 0GH/s
8: 0GH/s
Bank 3
9: 15.677GH/s
10: 10.107GH/s
11: 11.167GH/s
12: 13.758GH/s
Bank 4
13: 9.621GH/s
14: 9.893GH/s
15: 10.165GH/s
16: 20.916GH/s

Rig 2:
Bank 1
1: 0GH/s
2: 0GH/s
3: 0GH/s

14: 0GH/s
15: 0GH/s
16: 0GH/s

I'm certain everything is hooked up correctly. I have checked several times. I tried replacing the PSU and that didn't do anything. I am using a 1200w to run both full rigs. I'm sorry if this is covered... (I'm going to go back and read through this thread now.) Any quick suggestions though? This thread is so long..

I'm not sure if this matters, but it seems the two rigs might have different firmware versions. One says this on the main admin screen the other does not: "Attention! Please set pool difficulty on your pool to 32-512 depending on your hashrate. Low difficulty setting will result in work queue overload, and drop your hashrate substantially. If running a full unit, please make sure all cards are installed in slots written on the back side of the card. Due to SPI bugs, the miner may need to be stopped and restarted using the buttons above."

  here good section to read https://bitcointalk.org/index.php?topic=287590.0


   I got 2 Hboards stop working yesterday.


ps: did anyone return bad hboards to Dave for replacement and I got 2 Hboards for replacement and need to return bad Hboards to Dave.  I am waiting for information to return bad hboard for long time now.

  You need to start  one at time to check for bad Hboard.

.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:

Code:

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

[CoinHoarder]

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?

 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

[AMD FTW]

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

[goxed]

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

[goxed]

If you donot add heatsinks to the regulator area, cards will cycle. The real point of adding heatsinks to the ASIC is to keep the regulator cool. Add sinks to the regulator and atleast the bottom 2 rows of ASICS and reduce STRESS in your life .
BTW, I also did another mod, but I will not advise anyone to do that unless they know what they are doing. It's obvious to the astute user if you look at my H-card very carefully.
