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

[AMD FTW]

Fans overkilled.

This setup is cheaper and can flow a hell of a lot more air and is more efficient and quieter than any 120 or 140 mm fan. For six fans I spent under $120

My current setup:


 stable at 205GH/s w/ 6 v1 H boards (1 August & 5 October). Pencil mod on the August board, no changes to October boards. I've removed all heat sinking and other physical modifications from the August board.

It took quite a bit of shuffling to find a board order which worked well.

The cardboard prevents board flutter/vibration in the high speed airflow; this cut down on SPI errors noticeably. It also directs more of the airflow toward the power supply section of the boards.

I bought a few of these guys: http://www.supermicro.com/products/chassis/4U/748/SC748TQ-R1200.cfm
lightly used from a local recycling place for $30/each, 1200W power supplies included, so the whole thing is now
rack mountable in 4U, little single included. With the case on it's quite clean.

The rPi controls the little single w/ cgminer; stratum proxy for chainminer runs on a remote host because it's much easier on the rPi that way.

what connector do the non pcie mboards use? trying to come up with an answer to MBP's flavor text:

16 chip Hashing Board to be used with the Master board (or separately if you’re a real hardware do-it-yourselfer!)

[Littleshop]

My current setup:

Those two should not have to live together.   The Bitfury's have to put up with all of the heat and noise from their loud neighbor who steals all of the electricity.

And contributes only 12% of the output of the whole box! I know, I totally agree... it's very unaesthetic ^_^

A great deal indeed, I would have gone that route too if you were able to score a few of them.

Guys, we made good progress today, shipping all of the product we had available.  Tomorrow I expect to receive a mountain of stuff that was shipped through the week.  I'm not sure why it piled up to the end of the week, but we are all planning to work.  The shipping crew just left after prepping boxes for tomorrow morning's ship out.
They will then use the rest of Saturday, and all of Sunday to prep orders for Monday shipping.  I think we may have everything out by Tuesday or Wednesday.

A few things to note about these rigs:

-out of the box, a full rig will do between 550 - 600GH/s.  These boards are factory volted to .865v
-if you don't put solid airflow on them with fans, the cards will cycle - the regulators will get too hot, shut down, cool off, restart, etc.
-use the three case fan connections for sure.  A box fan will also help!

I'm measuring 600w to the power supply with a rig running at this rate.  PLEASE use two seperate PCIe power cables to power your rig.  Check cables for warmth - lets be safe folks!  Be careful trying to plug too many rigs into a single power circuit - 15 amps on a 15 amp breaker is NOT ok

The cards are very strong and so far very consistent.  There are still some EOL's and a few noisy cards too.

I really hope you are all really happy with these hot rigs!

Cheers,
Dave

I have 200 aluminium heatsinks waiting to slap all over my boards :X

What are the specs for the heatsinks?

14x14x7mm aluminium with thermal tape on back

[Cablez]

Are there any pics of the boards with the trim pots yet?  I am ready to go beyond the pencil if I can get 550+.

Some power supplies have a heavier gauge wire for the pci-e cables. OCZ uses a heavy gauge. Silverstone, Evga and Enermax don't, at least on my power supplies. Given a choice I would go with a heavier gauge for doing something like this.

Good point. Max of 2x 600w rigs on a 15 amp circuit, 3x 600w rigs on a 20 amp circuit.

Jared has been working to improve the network configuration for these rigs.  Here's how it works now:

-on boot up, the card will get the dhcp range of your network
-it will then take the .249 of this range
-you'll find the updated web UI at this address
-there's a network config button at the bottom that will let you change the IP of the rig

Jared also added a shutdown button at the bottom of the web UI.  Use this before powering down - we find that SD cards survive a lot better this way.

More cards arrived today and more are going out

Cheers,
Dave

I have been using 'sync' command before turning off power. In my experience the file-system problems seem to arise because the ext4 partition on /dev/mmcblk0p2 gets corrupted time and again.

I work with embedded devices running Linux from SD cards. I recommend that you check if the partition is in ordered mode or write back mode (ext3 has it and I am guessing it is also a setting in ext4). It should be set to ordered more to prevent corruption (default is write back mode on ext3). Worth checking if you haven't.

By the way when is order #703 shipping out (my wife wants to know)?

I received notification that all of my October orders have been shipped!  Happy camper here.

 OOH ! What order numbers and what sorta gear you gettin' ? Woot !

 Getting excited !

Update for v1 M board owners. If you want to use the latest build of chainminer with your version 1 M-board please do the following

a) Download chainminer master on your raspberry PI from github and unzip it

Code:

https://github.com/bfsb/chainminer/archive/master.zip

https://github.com/bfsb/chainminer/archive/master.zip

b) change line 6 in miner.h

Code:

  1 #ifndef MINER_H
  2 #define MINER_H
  3 #include "handylib.h"
  4 
  5 #define NDEBUG
  6 #define VERSION 1

c) make

Code:

cd chainminer-master
make
cd ..

d) move /opt/bitfury/chainminer

Code:

mv /opt/bitfury/chainminer /opt/bitfury/chainminer_v1_original

e) copy chainminer-master directory to /opt/bitfury/chainminer

Code:

cp -r chainminer-master /opt/bitfury/chainminer
 

f) mine with latest chainminer goodness  

So I have updated the chainminer to the latest from github using these instructions and it seems to have gone well.  Boards started hashing again and it has been pretty stable for a week.  No hashrate increase to speak of and only a 2-3% decrease in HW errors.  Still that is better than nothing.  Thanks very much goxed.

Do the new M-boards have only two 6-pin power sockets and no other power input terminals? I'm uncomfortable having so much amperage flowing through these wires. My v1 rig with 12 H-boards is pulling only 400W from two PCIe cables and those connections are hot. I'm concerned about pulling up to 600W through the same kind of connection. Maybe I should desolder the 6-pin sockets and solder wires directly to the board?

I asked the same questions weeks ago on this thread...post 198
