GPU Overclocking Oddity

Ok maybe someone can help me out on this.

Last night I decided I would try overclocking the memory on the 8400M GS in my 1420.

I tried to use ATITool, RivaTuner, and nTune. None of them would overclock. What would happen is, I would set the slider and then as soon as I let go or clicked apply or ok or whatever, the slider would reset to the stock 500 MHz speed. This wouldn't happen after an amount of time, it would literally be, try to set it higher, let go of the mouse, and boom, right back to stock without any change. I've never encountered this before.

I am running the 162.13 driver from Laptopvideo2go.

Does anyone have any insight into why this might be happening?

 

i think people had the same problem with the 8600gt. i'd like to know how to overclock as well bump

 

yep Laptopvideo2go newer drivers dont let you overclock.
i got the same prob, when using Laptopvideo2go's 162... and 165 XP and it always makes the clock bounce back to original when trying to overclock.


solution:
There is no risk at all, feel free to try
IF you could pick this modded inf up with 165.01 installer from Laptopvideo2go aswell ( http://download.laptopvideo2go.com/nvidia/165series/16501.exe)

OR you could replace the nv4_disp.inf to 162.18's, it might work!

for Vista:
get ngohq nvidia-optimized vista driver and find nv4_disp.inf, then paste on to another driver

 

Has anyone here figured out how to get the Vista 32 162.18 drivers to over-clock with rivatuner.

These are the best performing 8600m GT drivers to date.
