Just like system memory, memory on a graphics card dictates how efficiently it can handle larger workloads.
Video of the Day
Typically, the memory on a graphics card cannot be changed; it's permanently fixed to the card. However, some graphics cards are built into a computer's motherboard, allowing a portion of system memory to be dedicated to only the graphics card.
Changing the amount of dedicated video memory can only be done by accessing the BIOS (Basic Input/Output System), which is the system used for configuring motherboards.
Step
Restart your computer.
Step
Open the BIOS by pressing the appropriate keyboard key when the system is starting up. This varies with every motherboard; refer to the manual or the manufacturer's website.
Step
Look for a menu item that references hardware or video memory. Use the keyboard to navigate. There is a navigation legend located in every section of the BIOS to assist you. Reference the motherboard manual or the manufacturer's website if you can't find the appropriate setting.
Step
Adjust the amount of video memory. You will be limited by the motherboard; it has a number of preset memory amounts to choose from. These cannot be altered.
Step
Save settings and exit the BIOS.
