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.

Good luck! And again, re: self modding - you toast it, you eat it!
