Laptop GPU downclocking from OC

[JumBie]

I am currently using a laptop that has a 9600m GT 512mb DDR2, I realized through research that it was easily overclockable. I downloaded Nvidia tools and overclocked my gpu.

Stock
Core: 500mhz
Shaders: 1250mhz
Memory: 400mhz

to

Core: 640mhz
Shaders:1650
Memory:570

It was working perfectly fine, the new numbers were showing up in CPU-Z under GPU. Then all of a sudden today, it downclocked to 400/800/400....which isn't even the stock speeds. When I tried to overclock it again the new numbers will not show up in CPU-Z, it just remains at 400/800/400. I have no idea what caused this to happen, anyone have any clues or ideas?

Have you restarted the computer? Sometimes Nvidia's drivers do this. It has happened to me.

Try reinstalling the drivers

I tried uninstalling, and reinstalling. Then restarting, etc....no budge. Its now stuck at 400/800/400.

What are your GPU temps?

I think your research may have given you some questionable information.

What are you using to overclock?

 

[JumBie]

Nvidia System Tools to overclock. There are tons of forums on people overclocking the 9600m gt, so I know for a fact that overclocks close to and higher than mine were achieved on this chip.

What are your GPU temps?

56 @ Idle and 74 during gaming. This is on the 400/800/400 profile.

On my old overclocked profile it hit upwards or 86.

Take a look at these screens that add to the confusion.

When playing a game the only thing that change is the memory usage and the temperature. Other than that the speeds never change.

Essentially GPUZ reads the new modified clock speeds, but the sensors are still showing this weird 400/800/400 profile clocks as the ones in use. To make matters worse, the clocks shown under default clock don't match that of the ones under sensors.

I have uninstalled all drivers and anything remotely related to nvidia on the laptop. Upon restart I noticed that the GPU was pushing normal 2d desktop clocks, and then it would randomly switch between:

Core 500mhz
Shaders 1250mhz
Memory 400mhz

which is its stock normal clock, to:

Core 400mhz
Shaders 800mhz
Memory 400mhz

and it just keeps switching between the two profiles at random times...the laptop is not overheating so I have no idea what the deal is. Anyway I can force clocks to the card? Apparently Rivatuner, Ntune, and Precision arent doing the job.

EDIT:

In CPU-Z I have two 2D performance profiles for some reason. One is set at 275/550/250 and the other one is set at 400/800/400. The 3d profile holds my overclocked numbers however it appears that even while gaming it only uses the second 2D desktop clocks (400/800/400) how can I get the GPU to use the 3D application performance profile when playing games?

UPDATE

Uninstalled everything again, used stock windows 8 drivers and used nvidia system tools to overclock. Worked fine, played a game of dod source with OC clocks and everything went fine. GPU-Z, CPU-Z were both showing the new clocks, after exiting the game the new clocks will no longer kick it. It keeps using the 400/800/400 2d profile.

In SHORT GPU is stuck in 2d clocks profile when running 3d applications.
