something strange with nvidia tnt2

[Donald Duck]

I've got a tnt 2 with 32MB ram the strange thing is that when I checked it with winxp and sisoft sandra it says that it has only 16MB ram. The strange thing also is that when I boot I see on the screen the logo that I have the graphic card nvidia tnt2 with 32MB ram any ideas?? :?: :?: :?:

 

Thanks in advance
