hey one of my miners is defective. It doesn't get an IP address. I just plugged the second one it, and it came right up.

1.2Th is impossible and the reason why you got no instructions on how to overclock the Dragon units is because it will go up in smoke if you push it (Cheap-ass components)

This is on your own risk: (aka hardcore miner mode)

How to overclock a Dragon 1Th unit:

Turn it off, then on again.
SSH into the pi
Locate the CGminer folder
Create a .sh , name it to whatever you want (nano Overclock.sh  <-- just a example)
Add:


1: Keep the ", add pool adress
2: Wallet or Username, depends on which pool you use
800: Default clocksetting, you can push it to 850Mhz but no more.

Save the file
Now you need to install screen for the pi, to keep the resource running even when you logout of the pi.


Now you´re in screen
Locate the CGminer folder
Now you need to run the .sh


Press CTRL + A + D to close screen
You´re still connected to the pi via SSH.


Now you´re not connected to the pi anymore and your Dragon is running the chips in overclocked mode.
Don´t connect to the web frontend! (If you do, you need to start over from step 1 again)
Check your hash status via the pool.

IMPORTANT:

If you got the 32 chip version it´s already clocked to 900Mhz (Instead of more chips they used a little more expensive components to handle the over clock, but saved a bunch of money since the A1 is more expensive). DO NOT EVEN TRY TO OVERCLOCK. Add blades instead.

If you got the 40 chip version you can push it to 850Mhz as long as the unit is in a cold room. The 850Mhz setting makes the Dragon pull 1000-1100 watt, so don´t expect the stock PSU to survive to long (unless you got the 2x650w psu version) but should give you 50-100Ghz more to play with.

If you turn off the unit or experience power outtake, just start screen on the pi and run the .sh again and you´re back on over clocked chips again.

Say thank you and send me a beer here: 1Nm46UJo57NAuwA9XdAoaYQpUk4Phg2Ueu  

EDIT: Thanks for the beer anon! (I like beer, so keep it coming if you feel that this guide helped you to earn some more coins   )

Edit 2: Cleaned the how to up a little. Added some text so now anyone with a little knowledge should be able to over clock.  You can create multiple .sh for different Mhz settings and pools ex Eligius.sh, Bitminter.sh, Ghash.sh and so on.

While you can change a single PHP file to make the interface in english there were a lot more problems than that present. For one there is not autostart/autorestart and the cgminer process was started directly from the php button(BAD). I ended up completely overhauling the interface based off of some other cgminer php UI files floating around https://github.com/jameshilliard/28nm-www . Whoever made the stock GUI and pi image did not really know what they were doing IMO.

Prochedure:
ssh into raspberry pi using the IP on the screen or an ip scanner, its IP should be between 192.168.1.1 and 192.168.1.254
default username is "pi" and default password is "raspberry"
you can either use sudo to make these changes or just make a root account
To make a root account:
then enter your password
you can then use a GUI tool such as winscp to move files around
copy or clone my git repo to /var/www
you will then need to place the startup scripts and other files in the right places
simply follow the matching paths for my var opt and etc folders from the root directory and place those files in their respective folders
you will need to chmod all of those files in var opt and etc to 755
you will probably need to chmod /var/www recursively to 777
you will then need to run:
you will probably get an error but it will still work after this command
From there you will see the new webui with minersource in the top left hand corner.
Please submit a pull request if you come up with any improvements, I hacked this together in about 12 hours so I'm sure I missed some stuff. Currently it will not set a webui password properly, although you couldn't do that to begin with, that should be an easy fix but I just haven't had the time to go through it. I haven't figured out how to get the IP to update on the screen either with the UI I made.

All you need to do to change to english is change a single PHP file on the pi

All 5 of my antminers are running and I'm getting 1.51 to 1.6 ghash/s out of them however the site only shows a little over 2ghash/s.  Is it issues with the site?

I guess you mean next 24 hours.
 
Pool luck 166%, 84%, 90%, one 10+h block and one ~6h, pool ~777Th, network ~27Ph

The pool should find ~4 blocks daily, we have 11 ... if we find the next block before 2014-02-14 17:00 we are fine ... or our next round should be less than 20h to keep 100% daily luck.
To recover our weekly luck we need to have (approximately) round 21672 out of the stats page by the end of 15-th or otherwise twice the normal rounds per day ... on average 3h rounds, so yes we should have few more 'less than 3h' rounds in the next 72h and probably at least one in the next 24h

Don't ever go to Las Vegas.
