Enabling Resizable Bar for Creative Professionals: Gpu and Motherboard Tips

by

In the world of creative professionals, such as 3D artists, video editors, and game developers, having optimal hardware performance is crucial. One of the recent advancements that can significantly boost productivity is enabling the Resizable BAR (Base Address Register) feature. This guide provides essential tips on how to enable Resizable BAR for your GPU and motherboard to maximize your system’s capabilities.

What is Resizable BAR?

Resizable BAR is a feature that allows the CPU to access the entire GPU memory buffer at once, rather than in smaller chunks. This can improve performance in demanding applications by reducing bottlenecks and increasing data transfer efficiency. Enabling this feature is especially beneficial for creative workloads that require large data sets, such as rendering or video editing.

Checking Compatibility

Before enabling Resizable BAR, ensure your hardware supports it. Check the specifications of your GPU and motherboard:

  • Supported GPUs include recent NVIDIA GeForce RTX 30 series and AMD Radeon RX 6000 series.
  • Motherboards should have a BIOS that supports Resizable BAR, often labeled as “Resizable BAR,” “Above 4G Decoding,” or “Resize BAR Support.”

Enabling Resizable BAR on Your Motherboard

Access your motherboard’s BIOS or UEFI firmware settings to enable Resizable BAR:

  • Restart your computer and press the BIOS access key (commonly Del, F2, or Esc) during startup.
  • Navigate to the Advanced or Peripherals tab.
  • Locate the setting for “Above 4G Decoding” or “Resize BAR Support.”
  • Enable the setting and save your changes before exiting BIOS.

Enabling Resizable BAR in Your GPU Drivers

After BIOS configuration, ensure your GPU drivers are up to date and support Resizable BAR:

  • Download the latest drivers from NVIDIA or AMD official websites.
  • Open your graphics driver control panel (NVIDIA Control Panel or AMD Radeon Software).
  • Navigate to the “System” or “Global Settings” section.
  • Look for an option related to Resizable BAR or Smart Access Memory (SAM) and enable it.

Verifying the Feature is Enabled

To confirm that Resizable BAR is active:

  • Use tools like GPU-Z or HWInfo to check GPU features.
  • In Windows, open Device Manager and verify that your GPU is correctly recognized with the feature enabled.
  • Some games and benchmarking tools also report if Resizable BAR is active during performance tests.

Tips for Optimal Performance

While enabling Resizable BAR can improve performance, consider these additional tips:

  • Keep your BIOS and drivers updated regularly.
  • Ensure your power supply can handle the increased performance demands.
  • Combine Resizable BAR with other optimizations like fast storage and ample RAM for best results.

Conclusion

Enabling Resizable BAR is a straightforward process that can yield noticeable improvements in creative workflows. By ensuring compatibility, updating firmware and drivers, and correctly configuring settings, creative professionals can unlock the full potential of their hardware and work more efficiently on demanding projects.
