Hey guys

I just upgraded my Toshiba Satellite A100-906 from 1GB to 4GB(2GB x 2GB).

And the official Toshiba webpage it says 4GB maximum.

So I formated my Toshiba from Windows XP 32 bit to Windows 7 64 bit.

But when I checked the properties on my Toshiba it says 4GB (usable 3GB)

And my GPU is NVIDIA 7600 GO

How can i full use my 4GB memory?



If you guys can help me i would be very thankful

it is saying 3gb usable because its likely you are running a 32bit os... go to start right click on my computer and then properties and check the system type

most likely being used by the gpahics card etc, you wont be able to utilize all of that most will share it for video memory but not a full GB.

But it appears to have a dedicated graphics card with its own video ram and is not using shared system RAM, I think.
