Memory on a graphics card

Just like system memory, memory on a graphics card dictates how efficiently it can handle larger workloads.


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 1

Restart your computer.


Step 2

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 3

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 4

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 5

Save settings and exit the BIOS.


Dedicating more memory to the video card comes at the expense of system memory; make sure you have enough system memory to run properly. If you find your system is running too slowly, repeat the above steps and reduce the amount of video memory.
