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

[cypherdoc]

Sorry to post technical on the sales thread but does anyone have or know where I can get an image for the V3 M board.  Nothing on the OP and not getting answers from the other threads.
Thanks!!

This is what I'm running.  It's set up to use bfgminer, not chainminer.

https://dl.dropboxusercontent.com/u/57535575/bitfury-sd-card-customized-2.img.xz

Once you have it installed, you might want to update bfgminer:

Code:

cd bfgminer && git pull && make && sudo make install && sudo shutdown -r now

the *.img.xz won't open up on my raspi.

You don't open the image on the raspi.
First the image is compressed with .xz so first extract it to get the actual .img file
Then use whatever disk util you prefer to clone the image to the SD card.

ah, can that extraction be done on a Windows machine or does it have to be linux?

I do believe they have binaries for win32/64.

Where is your HF order & endorsement?

This one is working because my boards are hot.  But how do I get into it to change the pools.

[bobcaticus]

The official V3 build and a How-To guide are located on the product pages:

https://megabigpower.com/shop/index.php?route=product/product&product_id=50

I highly advise that novices use this method.

You can change pools via the http page, but if you need to tweak it - then SSH into the rig and use these commands (also in the How-To)

sudo nano /run/shm/.stat.log - checks chips
sudo nano /opt/bitfury/proxy_pools.conf - pools
sudo nano /etc/network/interfaces - IP setup

Is it just me, or is this latest batch of rigs tuned lower than the previous v3's by default ?

Feel silly for sounding like I'm complaining, but my prior two rigs easily run north of 525GHs, and this latest one seems tuned for a steady 500GHs. Have not taken a multimeter to the latest cards to measure voltage yet. Probably will this weekend.

I just asked Dave that this morning:

"Our older cards ran at a higher chip speed (55,56) and they worked fine.  Newer cards (voltage adjustable) need to run at a lower speed.  I think some customers are getting the wrong speeds, which will cause newer cards to overheat"

Use voltmeter to check board voltage (recommended .8v). 
- Grab ground from any GND on the M-board
- Touch the red probe to the top of the Pulse inductor on the board
- You can even turn the screw while its plugged in and powered up

 Thanks. Have plenty of cooling on these guys, and have them situated in a Spotswood case. Will aim to do some tuning this weekend. Love the addition of the metallic areas on the back of the cards to help dissipate heat.

One thing that does suck about these rigs is that they do not run very stable when fully populated (ie all 16 cards installed).

This is very dependent upon power supplies.  You need a beefy PSU with stable 12V rails in order to keep the amperage even to all 16 cards.

i keep getting ip conflicts with my multiple rigs.

anyone have a good strategy for avoiding this?

Hmm, do you have any recommendations. Believe it or not I'm running one full rig with a seasonic 550 watt 80 plus gold psu but I'm thinking of buying something more beefy. I have in mind the AX860 series.

Is there any way to reliably do fail-over with the mining app Bob?

The Seasonic 850w X Gold works really well.  We can't really recommend a certain brand, but I can highly say this works well

I'm assuming with power?  You could in essence plug one unit into the pci-e and run another thru the wires at the other end.  I've been told you don't need to worry about over-juicing the M-board.

  maybe he/she meant mining s/w auto to backup pool.

You would have to use your own stratum proxy/gateway or use bfgminer. Chainminer by default does not offer failover support. On the miner's web page if you set multiple pools it just splits the workload.

as yes, as BTCGuild took a dive tonight.   I read something in the other 230 pages that went over the process.  I'm going to say that the other 2 fields in the proxy pool don't switch over when the main one goes down?

Personally, I went over to p2pool so I don't have to worry about anything... unless the cat unplugs my computer again.

 I suspect this is the cause of all your problems right here That's BARELY enough to power a full rig.

 I <3 anything Corsair in the 850W range for these guys.
