How to Use an SD Card to Improve Video Card Memory


Video cards, also known as graphics cards, are expansion cards that send graphical information from your computer to the monitor. You may be unable to perform certain tasks if your video card doesn't have enough memory. For instance, when trying to play a high-resolution game that demands too much from your system, you might see a message that you do not have enough video memory, and you won't be able to play the game. However, you can improve your video memory by connecting an SD Card to your computer and using ReadyBoost. This feature uses memory from the SD Card to supplement your computer's RAM when your video card needs it.

  • Insert the SD card in your computer's SD card slot. On a laptop, this slot is usually on one of the sides. On a desktop, it is usually on the front of the main unit. The "Autoplay" dialog box will then be displayed on your computer's screen.

  • Click the "Speed up my system" option displayed beneath the "General options" section. The "Properties" dialog box will then be displayed.

  • Click the "ReadyBoost" tab displayed on the upper region of the "Properties" dialog box.

  • Select the "Dedicate this device to ReadyBoost" option by clicking the check-mark displayed beside it. This will use the maximum available space in your SD card. The minimum amount required for ReadyBoost is 1 GB; however, an 8 GB SD Card will really improve your system.

  • Click the "Apply" tab and then click "OK." ReadyBoost will begin to speed up your computer, including providing extra memory to your video card when needed.

Tips & Warnings

  • Computers that have a solid-state drive (SSD) might not see the ReadyBoost option when an SD card is plugged in. This is because SSD drives are so fast that using an SD card with ReadyBoost offers no benefit. In this case, you may see a message saying: "ReadyBoost is not enabled on this computer because the system disk is fast enough that ReadyBoost is unlikely to provide any additional benefit."
