Overclocking problem with Go 7900 GS

post #1 of 5
Thread Starter 
Hey, in general I could't change any clock or memory setting on thos card. Nor with riva tuner, neither with Ati tool. There is even such a option in Nvidia control panel, but after you hit apply it is reset to its default options.
Any help?
Windows Vista 32-bit
Nvidia GeForce Go 7900 GS

Does it immediately transfer back after using nTune, or after a restart, if the latter then use Rivatuner again and change the setting where it erases overclocks after restarts off.

It's a mobile card. Some laptops will prohibit overclocking (on a BIOS level).

Basically if you can't do it with those applications, it's not possible (ok, if you are an electrical engineer, sure).

I had this same problem with my x1400, didn't budge.

Actually my idea is to underclock this card. You are right that they tend to go too hot.
It is pity that BIOS prevent to change any of this options (other way it goes automativally in three modes - 2D (100/100) 3D low power (200/300) and 3D performance (375/500).
The problem is that even when I simply watch movie it goes to third mode and heat up to 78-80 degree. (It is not very cool in normal mode - 60, but anyway it is better than 80).
