Also is this in its on .sh file? or are you typing it in to a terminal everytime?
I am just typing it into the terminal every time.
First, can you confirm you have some active cooling? above 100Mhz, newpacs get very hot and will jump into thermal runaway and shutdown/burn out very fast.
What exactly is happening when you try to overclock? Is it throwing an error or just not allowing you to set it above 100Mhz?
Yes, I have 2 120mm fans cooling them atm. When I try to overclock them for a split second they show 200 Mhz, then they all reset back down to 100 Mhz. No errors or anything is getting thrown.
Also make sure there's not a config file overriding your command line settings.
Currently, I don't see a config file titled cgminer.conf. Is this what you are referring to?
I got them to work. I ended up scrapping my ubuntu install and just downloaded raspbarian. They ended up going to 200 Mhz. Thanks everyone!
