I have the latest version of chainminer. How could not detecting all the chips not be a main board issues? It happens no matter what cards I use in bank 4, but is fine if i just populate banks 1-3.

I already examined the boards and a friend of mine examined them under a microscope. No visible issues.

Ive tried everything basically, its fucked. Its unstable as hell, I can leave it come back an hour later and the entire 2nd bank will have crashed...

Card regularly dip from 30gh down to 2-3 then back up again, is that normal? (Running on manual)

I had the same issue, for me it was the psu.
Measure the 12V at the end of the M-board (near D2, D3, D4), for me it was only 4V... Exchanged psu and it works.

Help!

I have received a kit with 4 cards, but the unit shuts down as soon as it detects a card.

[2013-10-22 07:37:03] BITFURY slot 0: 16 chips detected

I have tried default chainminer and bfgminer. All 4 cards do the same, ie plug in any slot a1 b1 c1 d1 then miner starts and the power supply stops and i have to take out the paper clip to turn the power back on.

I have bought a nexus nxstek NX-5000 550W. Very quite supply, but is there a chance it is just shutting down? Or does the raspberry pi shut the power supply down? One thing i noticed is the 2 6 pin connectors are directly connected. So one extends the other. Should they be discreet cables to the power supply?

I'll get a new power supply today, but if anyone has any ideas, please let me know!!

sounds like there's something drawing too much power so the psu protects itself by shutting down. Are you connecting the hashcards the right way? Try different combonations of psu cables, multi-rail PSU's can be problematic.

punin, first, thank you for your hard work.

second, when will the shop reopen with H boards? I am very interested in buying more, if the price is right.

NOTE

Due to my personal epic screw-up the SD image does not contain a working binary. And on top of this some orders were shipped without instructions also Tongue

We have whipped ourselves vigorously here over the weekend and will try to improve our process so these bloopers don't happen in the future.

Here's how to get your miner working:
1. Check your router for bitfury IP
2. SSH into the raspberry pi (username pi password raspberry)
3. Run following commands:

Code:

cd /opt/bitfury/chainminer
sudo make clean
sudo make
sudo killall screen
sudo /etc/rc.local

You should now be mining. You can check the web interface of the miner with a normal browser and setup your pools there (use the IP that you used for SSH).

Dig your freedom

I receive my order #97x on Friday afternoon. Thx Punin !

After dealing with the problems associated with the work of four modules at the same time, now hashing ~ 30 Gh / s per module.
Today I'll start manual tunig chips. Over the weekend, I gathered some logs for this purpose.
For all who wait for H-Modules. Please check it for shorts before insert and power up.

So your time needed to keep the miner running (maintenance) is free/worthless?
The wear and tear of components involved (e.g. PSU) has no monetary value?

A decent PC PSU is < 1BTC these days, so you should consider writing it off as part of your H/W cost to reach breakeven, and so far (1 year+) all my PSU's are still soldiering on - I do run them at about 1/2 rated load, and I did buy good quality ones though.

My FPGAs which are still making BTC profitably (if painfully slowly) take < 5mins/month of my time. If your setup is stable, it shouldn't keep you busy IMHO!

Has anyone discovered how to put the additional pools on failover?

Does one have to upgrade the software in order to be able to do that?

over at KNCMiner someone seems to have found a way to do it with cgminer. Maybe it works in a similar way with chainminer.

http://forum.kncminer.com/forum/main-category/hardware/6990-how-do-you-switch-pools-any-feedback-would-be-great

I found KNC web interface for pool management consistently inconsistent. I would make change that cgminer picks up per SSH, but web interface still shows old version.

I ended up using cgminer pool management interface more often than web interface, and now I have 3 pools coded in with a failover, and I'm so far super happy with this setup. The downside is that KNC web interface no longer shows pool management page (I guess KNC code has trouble reading cgminer.conf file with more than couple of lines ;/)

If mining is your hobby, then maybe your time is "free".

hopefully you would include the psu in your cost analysis. Additionally to your mining income, you have a physical piece of hardware with some resale or collectible value.

as for time/maintenance - its free if you enjoy tinkering, and these systems are quite stable once configured correctly.

so you can keep mining with it long after the others cost more to run in electricity than they deliver in BTC.

Well, if you call everything above 0$ profitable, then yes.

Well, yes, I would!

If I put $1000 in the stockmarket and it was worth $1050 - i.e. 5% more at the end of a year, I would have ROI - why do people in the mining community think that a miner is a magic machine that turns 1BTC into 100BTC in one month?

IMHO some people on here really do seem to be smoking some infinite difficulty crack! Money (hashrate) will not keep flowing into the system if nobody is making any money from mining!

The chips are currently 19Euro (+VAT) or ~0.15 BTC, and will pay for themselves in ~40 days. This chip is more efficient than some of the 28nm ones, so you can keep mining with it long after the others cost more to run in electricity than they deliver in BTC.

Once they've cleared the October backlog (and I did get my early oct chips in early oct as promised) I hope we'll be able to just order off the shelf like from Farnell
