Awesome, then you are not running a SENSE based ROM. Basically, when you open SetCPU, you have a few numbers on the screen like 245 MHz, as an example.
The bars in the middle.. The top represents the MAX speed. And the bottom the MINIMUM speed. Don't move the MAX bar completely to the left, even with the bottom bar. Can cause conflicts.
Anyway an example of a good setting would be.
MAX: 384 MIN: 240
This will give you a better deal battery savings. Including your personal setting on the device of course.
Under the Profiles Tab..
Make sure ENABLE is checked..
Click on ADD PROFILE..
CONDITION: Screen Off
MAX: 245
MIN: 245
Scaling: ondemand
Priority: 100 (HIGH)
SAVE..
This will make your device run as the lowest CPU setting possible while your screen is off. Saving loads of battery life.
Also, say you want to play a game and it runs sluggish.. Change your main settings to MAX and MIN: 11360. This will help use more power while you play the game. It will be SMOOTH AS BUTTA! Change the settings back to your preference when your done.
Hope this helps ya out.
