Adjusting these allocations can make a noticeable difference, especially if you’re running memory-intensive applications or games.

In the following sections, we’ll explore the essential steps and considerations for optimizing RAM allocation to your AMD APU. Whether you’re a casual user or a tech enthusiast, gaining control over this setting can unlock better efficiency and responsiveness from your computer.

Accessing and Adjusting BIOS Settings to Increase RAM Allocation

Allocating more RAM to an AMD APU primarily involves modifying settings within the system BIOS or UEFI firmware. This is because integrated graphics in APUs use a portion of the system’s RAM as video memory, which is configurable through BIOS parameters. To begin, restart your computer and enter the BIOS setup by pressing a specific key during the boot process, often displayed on the screen (e.g., Del, F2, F10, or Esc).

Once inside the BIOS, navigate to the advanced or chipset settings menu. The exact menu names vary by manufacturer but generally contain options related to integrated graphics or video memory. Look for entries such as:

  • UMA Frame Buffer Size
  • Integrated Graphics Share Memory
  • DVMT Pre-Allocated
  • Graphics Aperture Size

These settings determine how much system RAM is reserved for the APU’s integrated graphics. By increasing these values, you allocate more memory to graphics tasks, which can improve performance in games and graphical applications, especially those reliant on GPU resources.

Step-by-Step Process to Allocate More RAM to an AMD APU

  • Enter BIOS/UEFI: Reboot your PC and press the key to enter BIOS setup.
  • Locate Integrated Graphics Settings: Navigate to advanced settings, chipset configuration, or similar sections.
  • Adjust Shared Memory: Find the setting that controls the amount of RAM shared with the APU. It might be labeled as UMA Frame Buffer Size or similar.
  • Increase the Allocation: Change the value to a higher size. Common increments range from 128MB to 2GB, depending on your system’s RAM capacity.
  • Save and Exit: Save the changes and reboot your system for the new settings to take effect.

It is important to balance the allocation: allocating too much RAM to the APU can reduce available memory for other system processes, potentially slowing overall performance.

Recommended Memory Allocation Values Based on System RAM

When deciding how much RAM to allocate to your AMD APU, consider your total system memory and usage patterns. The following table provides recommended shared memory sizes for common total RAM amounts:
