How to Allocate RAM to Video

By Charles Jackson

Integrated graphics cards share the system memory (RAM) to provide memory for graphics rendering. Allocating more RAM to the graphics card can provide a slight increase in the performance of some video games. It also means sacrificing more system RAM, which, in some applications, can cause a decrease in performance. Integrated video controllers are not suitable for playing most video games and they are mostly used in laptop computers to save costs and take up less space.

Step 1

Restart your computer and enter the BIOS on startup. On most laptops, press "F2" to access the BIOS; on most desktops,press "Del." If the key is something other than either of these, it may tell you on the post screen (the first text-filled screen when you turn on the computer). Alternatively, refer to your computer or motherboard manual.

Step 2

Navigate through the BIOS menus and settings by using the arrow keys on your keyboard and pressing "Enter" to select a menu or an option. Find the setting that allows you to change the amount of allocated video memory. In most configurations, it's in the "Advanced" BIOS Setup Utility menu.

Step 3

Locate "Video Memory," "Internal Graphics" or similar. Increase the amount of RAM as required. Most computers with integrated graphics will allow you to increase the shared system memory by as much as 512 or 1024 MB. If you have more available RAM, choose the highest value.

Step 4

Exit the BIOS with the "Save settings and exit setup" option. If you find that your computer runs more slowly, lower the amount of RAM allocated to the graphics card by repeating the previous steps and choosing a lower value.
