| 791216 | 2009-07-13 02:45:00 | From what I understand , graphics card use 'graphics aperture size' if the card doesn't have enough memory on-board and that graphics aperture uses main memory . Thing is , my laptop has an 'on-board graphics system' that uses main memory . I've set it to 16 Mb (lowest setting) and the 'Graphics aperture size' to 16 Mb (also lowest setting) . Does this mean the 'on-board graphics system' uses a total 32 Mb of main memory ? |

The graphics memory - fully-accessible only to the GPU - can be larger than the aperture - the CPU then has to tell the graphics controller to bank-switch the chunk of desired memory into the aperture so it can write to it. That should mean that your available memory should only be lower than actual by 16Mb - it should show up that way in the BIOS memory screen. |
