Sorry if I confused anyone, I'll try again.
I've been using the following script for several weeks now with one to four (4) newpacs mining successfully.
"cgminer -o stratum+tcp://stratum.(my mining pool address):3333 -(user name) (password) -p x --suggest diff 1 --gekko-newpac-freq 100"
Today I changed "gekko-newpac-freq 100" to "gekko-newpac-freq 150" in the above script.
And I saw no change in frequency..... It stayed at 100.00 MHZ and I waited for it to change for 20 minutes.
Currently I have four (4) successfully mining with the script changed to "gekko-newpac-freq 150" all Four (4) show a frequency of 100 MHZ with 22 plus change Gh/s.
Did you ever create a config file in cgminer? If so it could be overriding your scripts command to up the freq.
Be careful with cooling them I'm here because I ran my brand new stick at 125 and I'm afraid I may have cooked it. It ran great for hours then the hash rate went down and now it's hashing at 4.669 GH/s according to slush pool. I thought I wouldn't need a fan because my tower has a top and rear intake fan and it seems like the air was moving a lot back there by the usb port but I think I was wrong.
