I appreciate the offer wolfey but I am not comfortable doing that myself yet and can't afford to have you do it right now. Maybe when I get some more coins in the wallet...

Thanks to the help of everyone on this board I've been able to get my GSDs up and running for the past few days. I am using the stock cgminer 3.7.2 from the unicorn hasher guide and have noticed that at 850 mHz I am getting very few rejects and just a few HW errors even after 24 hours. I'd like to change the version of cgminer to the dbartle build so that I can increase the frequency in smaller increments, but can't find anything online to help with that. What is the process for updating the cgminer build? TIA

Try over-volting so you can have stable over-clocking with ZERO HW errors and probably even less if not ZERO rejects.
Just completed modding several for a customer and they are all now hashing away as mentioned.
Easily running over 500KH/s to over 650KH/s as expected. I've even seen peaks of over 750KH/s!
ZERO HW errors on all of them.
After tuning them all up, I'm seeing 1150MHz to 1250MHz as the most stable and profitable general operating range.
If you'd like me to mod your pods, feel free to PM me.
Here's a shot of my handy work, if you want to see how to do the mod yourself.
Like I've been saying, a 1/4W resistor will work just fine. Try to use 1% tolerance.
49.9K seems to be a pretty good general setting for overclocking up to 1250 stable.
Any higher than 1175MHz seems to be a waste at the pool i.e. wasted power, lower profits.
Just my .00002btc

A simple method to overclock Gridseeds upto 1050 MHz: Thermal Paste!

you should really make some pictures.
Also you should mentions to keep or not keep the "blue" stock thermal pad or not etc..
Most people here want to see "pictures or it did not happen" hehe
thanks anyway
No pictures needed. It's been proven long ago that these chips are not thermally challenged at all. I had one running without heatsink at 850 and then overvolted at 950. But you can't push past 850-900 just by smearing some paste on it, it needs the voltage mod.
DITTO!

i have updated to hashra v1.3 yet the old pool settings remain. tried reboot and restart but unable to update from the old pool address?

Thanks WTParker2 and Maxzilla, reformatted the SD card, put the new IMG on it and it worked like a hot cake!

The new LightningAsic controller firmware is released, please see: https://bitcointalksearch.org/topic/lightningasic-gridseed-controller-firmware-v3-554542

My first order of Gridseeds a while back from ZoomHash came with a Pi controller box. I never used it because I have set all my miners on an older Windows netbook. Anyways, I wanted to fool around with the Pi (ha!) and I can't get ANY video display. HDMI, DVI to HDMI, composite....nothing. Pi turns on (single red light).....but absolutely zero display. 
Any ideas?
Any ideas?
Zoomhash as already addressed this in their threads and on their website.
Contact them for the new SD image and there is an instruction sheet on how to fix it.
You will need a Windows computer with an SD card reader.
Sweet, I'll do that right now. I have a few spare 16GB SD cards so I'll just start with a brand new one. :-)

Never use psu (adapter) from China .. blown a few already.. use PC's psu.
Not sure what's the startup amp .. but your psu is 12v 10a? it can only support max 2 GS in dual mine mode.
Anyone know of a source for the ATX PCIe (and molex) to barrel plug adapters?
Seems CabelZ is no longer making them...

The option of ssh to check on miners? a link at least i had no luck.
This was posted by someone else...edited for clarity:

How to use screen:
screen -S ScreenName #starts a new screen session
"ScreenName" can be anything, it's just a name that you can use later to get back to it. This will give you a new shell. Start cgminer there.
Ctrl-A, then Ctrl-D will exit the new shell and will keep cgminer running.
You can now disconnect/exit SSH etc.
To get back to your cgminer:
screen -r ScreenName
To verify that it's indeed running in the background use this:
ps auxwww | grep cgminer
screen -S ScreenName #starts a new screen session

I have noticed that after you exit cgminer the screen session occasionally does not display new commands. I usually just exit and start a new screen session.

A link on how to use
""Useful options
Code:
sudo apt-get install openssh-server #if not installed during setup
sudo apt-get install screen #to run cgminer in the background
""
The option of ssh to check on miners? a link at least i had no luck.
It tried to do it via remote desktop with a vnc viewer and it would load the desktop but when i click on any thing it woudl not show the windows that were open on the remote machine. and i tried x11vnc instead and that would only show a gray window.

Ya i also tried to get ubunto 13.1 running but i get compiling errors and then the system don't fully work. i be trying it again today. i would even pay .1 btc for a good guide for a fresh install. the one i found in the other main gridseed discussion thread worked ok until i had compiling errors and did not know what to do.
Install Ubuntu Server 12.04.4 LTS: ubuntu-12.04.4-server-amd64.iso
Update Ubuntu and install git
Code:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git
Install dependencies, compile then run dtbartle cgminer
Code:
cd ~
sudo apt-get install build-essential autoconf automake pkg-config libtool libcurl4-openssl-dev libncurses5-dev libudev-dev
sudo git clone git://github.com/dtbartle/cgminer-gc3355.git
cd cgminer-gc3355
sudo CFLAGS="-O2 -Wall" ./configure --enable-scrypt --enable-gridseed
sudo make
sudo ./cgminer --scrypt -o stratum+tcp://xpool.net:8820 -u x -p x --gridseed-options=baud=115200,freq=850,chips=5 --hotplug 0
That is all! Seems so simple but it took a lot of effort to get here.
Useful options
Code:
sudo apt-get install openssh-server #if not installed during setup
sudo apt-get install screen #to run cgminer in the background
That made it nice and easy to get running thanks. on ubunto 13.1.0 it worked.
BTC sent.

Just an FYI for those of you using a Rasp Pi...I've had 6 running on a Pi using HASHRA for over a week now with 0 restarts and 0 down time. Use HASHRA.
Yea, my HASHRA image works great, but does restart periodically. I just look at the web page and it shows how long it's been running, and I see the number reset periodically.Running 10 GSDs each on 2 PIs.
Even with the restart, I don't see any gaps in the charts at the pool, so the restart is very quick.
I should have a couple Green Pi's coming soon. I gonna learn this shit....easy!
