VPC-Z112 Nvidia Graphics 2D Clock Speed

Hi all. Have a Vaio Z112 with the Nvidia 330M. I know this gpu should slow down to ~150mhz when only running 2D apps. Looking at nvidia system tools and nvidia precision tool mine always seems to run at the full 475mhz regardless of what I'm using.

Anyone else experience this? Did Sony write out the slow speeds in their drivers due to the assumption we would switch to intel graphics when needed?

In nvidia system tools there is an area that shows 2d/3d clock speed. normally you would expect to see ~150/475 there...I only see 475. Basically it looks like there is no 2d-only clock speed.

Thoughts?

 

the slowing down works, but it will take a while. I think somekind of timer. So like ''if not 3d for xx minutes then 2dspeeds''

 

I have never seen mine at the lower speed. And I haven't played games in a week. Does Aero force the higher speed? Or running dual monitors?

 

No i use aero all the time and i checkusing evga precision tool

 

hmm maybe that's just the tool? I'm also using EVGA Precision and it's showing that my core clock is at 135 mhz.

 

Well it shows me pegged at 475 with never a slowdown...I wonder if I hosed something up in my install or bios. UGH Are you guys ever using two screens?

 

FYI guys after much troubleshooting it's tied to my second display. I normally have an HDMI 1920x1080 lcd monitor plugged in. the minute I plug that in the clocks are fixed at the higher speed. As soon as I unplug....speeds vary as they should. FYI....
