How to Enter the BIOS for Acer & Upgrade the Graphics Memory


The memory settings for the various components in your Acer computer, such as the on-board or after-market graphics card, are controlled in the system's BIOS menu. You can tweak the memory settings to get a better performance out of the device, which is a process known as "overclocking." Manually upgrading your Acer's graphics memory can lead to problems with the operating system, however, so it is a process that should be undertaken with care.

Things You'll Need

  • Storage device
  • Save any critical data you need to a storage device, such as a USB memory drive, in case there are any problems when you change the BIOS settings.

  • Power off the Acer computer and then power it back on.

  • Tap the key that your specific Acer model uses to access the BIOS menu when the Acer logo appears on the screen. Depending on the model it will either be the "Delete" or "F2" key.

  • Use the down arrow key to scroll to the BIOS entry labeled "Advanced Chipset Features." Press the "Enter" key to access the sub-menu.

  • Scroll down to the option labeled "AGP Aperture Size." Take note of the current setting, such as 16 or 32. Press "Enter."

  • Scroll over to the next higher option in the list of available AGP aperture sizes. For example, if the current setting is 32 scroll to 64. Press "Enter" to confirm the change.

  • Press the "F10" key to save the graphics memory upgrade and then press "Escape" twice to exit the BIOS and restart the operating system.

  • Open a graphics intensive program such as a computer game. Run the program for 30 minutes to see if the operating system crashes. Return to the "AGP Aperture Size" setting and upgrade it by another increment if you want to further increase the memory.

Tips & Warnings

  • The standard available settings for the AGP aperture size are 4, 8,16, 32, 64, 128, and 256.
  • If you need to change the aperture size back to its standard setting return to the "Advanced Chipset Features" menu and press the "F7" key. Press "F10" and then press "Escape" twice.
  • The exact names of the BIOS options can vary between different models of Acer computers, but the settings you change will remain the same.
  • Only upgrade the aperture setting by one increment at a time, as changing the video graphics memory settings can make the system unstable.
