I recently bought a AMD A10-5800k APU with Raedon HD 7660D Integrated Graphics and I can't seem to find out how to get the dedicated memory over 256 MB. That's paltry memory and I know I can make it higher but can't figure how. Does it do it automatically or something?
If you're referring to the amount of on-board memory being 256MB, then you cannot increase that amount. Since Windows Vista, the operating system automatically allocates additional memory to the graphics card.
