9300m G overclock lock

[ivan86]

Hell all im new here !!

I bought some day ago a notebook with a Nvidia 9300m G installed (Acer 5720ZG) i want try overclock a bit my graphic card but i dont know why every software that i used didnt work :)

I tried with Riva Tuner 2.11 and EVGA Precision but nothing... I have also tried change driver 177.92 178.13 and now i use 178.15 but anyway i couldnt overclock...

When in rivatuner/EVGA i try move clock speed and then click "apply" it reset to default value :S same for 2d and 3d

anyway can help me? thank you

Here some SS about core/shader/memory check how in 2d mode my memory speed is 799 Mhz and the go down to 400 in 3d mode :S... Core clock from 182 Mhz in 2d mode go to 297 Mhz in low 3d mode and then go to 432 Mhz in high 3d mode....

2d mode : http://img521.imageshack.us/my.php?image=lowsetzc5.jpg

low 3d mode: http://img407.imageshack.us/my.php?image=middlesetyg7.jpg

high 3d mode: http://img440.imageshack.us/my.php?image=3dsetjy6.jpg

Why my memory speed in 2d mode is 799 Mhz and then go down to 400 in full 3d mode ? shouldnt be viceversa?

I want try get 450 core / 900 shader / 850 memory but till now could not, i read in other topic that not all driver support overclock and sometimes you need also change some value in registry.. Can someonewith knowledge help me pls ?

Here my 9300m G in default http://www.notebookcheck.net/NVIDIA-GeForc...-G.11359.0.html

speeds are 400 for core, 800 for shader and 600 for memory... =>my value are different :S

And 1 more thing, the memory speed that show EVGA and riva tuner is the real one or i need 2x it ? i mean in full 3d mode i see 400 Mhz in rivatuner but the real speed is 800 Mhz or not ?
