I suspect however the onboard video chip itself is limited to that as a max. Run a search for the video chip used and see if it ever ran more than 128MB.
I recently found out how to open my BIOS and change the dedicated video memory. I need a good amount of memory for all the games I'm used to playing. But the thing is, in the BIOS, the maximum memory is 128 mb. Is there a way I can increase this to 256 mb or higher, without changing any hardware components?
Thanks!
