gpu idle clock stuck at 'low performance 3d' clock

guys! why my 9500m gs clock is stuck at 'low performance 3d clock' according to riva tuner? is it because of installing rivatuner? or 180.70 driver makes it like this? or maybe it's Nvidia physX? becoz i update it from 8.09 to 8.10

the default clock should be like this:
core clock : 169 mhz
memory clock : 100 mhz

now:
core clock : 275 mhz
memory clock : 200 mhz

i got 7-10 Celsius increase of gpu temp becoz of this. I tried uninstalling riva n then restart, but nothing. Tried to wait for 6 hours doing nothing, n still got my current clock.
why..?

 

If you have Vista, try putting your computer in power saver mode and see if it remains at those clocks.

 

Did you make any changes in the registry tab in Rivatuner? Is "Force constant performance level" enabled?

 

funny that u say that.. why i can't enable force constant performance feature? and i don't make any change with registry tab.

 

my current temp is not high actually, just around 57-60. But it used to be 49-52 C. I often leave my lappie on for more than 24 hours. So even the temp is still low, 8-10 C hotter must make a difference in my gpu aging...

 

Force constant performance = force higher clocks.
