Cant lock CPU to max settings

Hi I have a SONY FE590 with a Intel 1.83ghz Core duo, For some reason I cant seem to set the CPU to maximum power, Ive tried in both NHC and RMclock and in both when i set it to maximum power it still dynamically shifts between 997mhz and 1833 mhz but wont seem to lock to its max, Any Idea how I can acheive this?

 

Remove all of your other power management programs and set windows power management to "always on".

Use CPU-Z and mobilemeter to read to clock speed.

 

Tried that, IT increased the voltage but not the multiplier.

 

I believe there is no way to set it to always max, but someone correct me if I'm wrong. I have called asus because when I open cpuz it shows 2.0ghz, then 1 sec. later it goes down to 997. a rep at asus told me that its a smart feature built into the core duos in that if you're not doing too much or just light work, its only using half the speed, but if you're doing something more intensive, it kicks it up to the max, its an auto feature that you don't have to worry about. next time, open cpuz and try do a cal for pi to whatever digit, and you'll see that it goes to the max in cpuz automatically and comes down to 997 when its done calculating. pretty ingenious feature imo.
