how can i increase the video memory of my computer?

You buy a hot video card. I've not seen or even hear of a video card whose memory can be upgraded.
you can't increase it because its just set up that channel, you can either buy a spanking new graphics card or overclock it which is not a good theory because your graphics card my overheat or the power supply won't supply enough
