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

[bitcoinlord]

With 1TH/s miners from big bitcoin miner mfgrs coming out in 2 months, I'm hoping to see this Bitfury 400GH/s system selling price to be reduce to $4,000 or less next month to justify the ROI. (approximately 80+ days to break even)

Does this seem reasonable instead?  I'm NOT trying to buy 400 dollars worth of heatsinks.

Also forgive my ignorance but do I remove these white peices of paper or are they used to give a good contact for thermal paste?

You just peel them off.

If you buy 300 of these you can chip a full kit for about $75

And I've had no component go over 60 C with these on

Wow thanks I wasn't totally sure and didnt want to ruin them.  Looks like they tack to the boards too!  Come off with force but leave no residue.

these are tiny and require a lot of peeling and sticking (they work well though - i have them on the fronts of each chip, but for the backsides i started using 35x35x6mm heatsinks that look great and provide a bit more coverage. (however, when placing them i had the distinct impression thay will not be easily removed (not that they need to be)

I plugged in my unit this morning

Noncerate: 579.391GH/s !!!!! Great job guys it's a very nice product!

Awesome hash rate! What are you cooling it with?

Just a fan I use to keep my apartment cool in summer and 4 case fans （I don't think the case fans do much).

I bought some heat sinks but I probably won't have them for another 2 weeks. http://www.volumerate.com/product/aluminum-cooler-heat-sink-chipset-for-ram-memory-w-type-8-piece-set-35816

   Grats and I think you may get it Friday if your miners are shippping out today.

Got mine up and running, but while the web interface indicates 70 GH/s (with two H-boards), BTC Guild is only seeing about 24 GH/s.  Last night, I noticed that the locally-indicated hashrate was jumping all around.  I have a high-flow 120mm fan blowing across the boards, but don't yet have heatsinks installed.  Am I seeing thermal throttling as a result?  I have a bunch of heatsinks on order, but it'll be a while before they arrive. Since previous versions were designed to run at a slower rate with just air movement and no heatsinks, is there a temporary adjustment I can make to at least get 40-50 GH/s out of my rig while I'm waiting?

I managed to get my Unit working Stable, it seems these guys want to be cooled in a specific way. I added 3 120MM fans to the top with 1 Box fan pushing air across it from the side. The real trick is it did not like the air on the same side as the regulator, no clue why but once I moved it to the other side it has hashed at 575-580 for about 11 hours now.

Now I need to move it off my workbench to where its going stay for good, lets hope my results do not vary. At least I have an idea what to do I suppose.

I asked Mega to stop my RMA for now since all the Units appear to work fantastic with Proper cooling.

This is what goxed wrote up for me to update chainminer on a V1 M-board and it worked.

cd ~/

a) mkdir chainminer-temp
b) cd  chainminer-temp
c) wget https://github.com/bfsb/chainminer/archive/master.zip
d) unzip master.zip
e) cd chainminer-master
f) change line 6 in miner.h
  f.1) vim miner.h  (do you use vim?)
  f.2) i
  f.3) change the line
  f.4) Esc
  f.5) wq enter
  f.6) you can try nano otherwise (nano miner.h)
g) make
h) cd ..
i) mv /opt/bitfury/chainminer /opt/bitfury/chainminer_v1_original
j) cp -r chainminer-master /opt/bitfury/chainminer

Note: Some of the new changes I made might cause problems with our rigs with those steps.  They also will need to do this after building:

Code:

cp /opt/bitfury/chainminer/miner /opt/bitfury/chainminer/miner_customer
crontab -l | grep -v "auto-miner-config" | crontab -

The first line updates a file I was referencing to determine which miner to use.  The second line turns off my automatic configuration so that it won't run at all regardless.

I accidentally cleared my crontab earlier, while trying to add my own logging script. Can someone show me their crontab for a v3 rig?

Question - I am suppose to receive a second EOL board tomorrow.  How do order them on the M-board.
The higher hashing one second to the end and then the lower one at the end of the line?  Does it matter?
I don't want any screw ups as I'm adding two more regular h-boards on top of this.

EOL cards must be at the end of a bank, because no cards after them (even other EOL cards) will be seen. Do you have a single-bank v1 M-board, or a 4-bank v2/v3?

EOL must be in the 4th slot of a bank. You can use up to 4 EOL cards per hboard

I have one of the first ones shipped...order #12.  It's V1 m-board but I thought it had four banks.  Maybe not.  Right now I have 4 cards and the EOL.  EOL last.

Pretty sure you can only use one EOL card then. Want to sell one to me?

# Edit this file to introduce tasks to be run by cron.
# 
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
# 
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').# 
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.

# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
