Introduction

Hey everyone, it's Panjino here, and in this article, we're going to talk about an important setting that many gamers overlook on their PCs – the resizable bar. Did you know that by enabling this feature, you can unlock up to 10% extra performance on your gaming PC? It's true, but unfortunately, many people haven't taken the time to enable it. In this article, we'll guide you through the process of enabling resizable bar on both AMD Radeon and Nvidia GPUs, and we'll also cover additional settings, troubleshooting tips, and benchmarking. So, let's dive in and maximize the performance of your gaming PC!

What is Resizable Bar?

Before we get started, let's quickly clarify what resizable bar actually is. You may also know it as rebar or AMD Sam, depending on your graphics card. Resizable bar is a feature that allows your CPU to access the entire VRAM of your GPU in one go, rather than in small 256MB chunks. By doing so, it reduces latency and improves performance, especially in CPU-bound scenarios. This feature is available on both AMD Radeon and Nvidia GPUs, and we'll show you how to enable it on both.

Compatibility Check

The first step is to check if your system supports resizable bar. Although it's available on relatively modern PCs, it doesn't necessarily require the latest components. To easily check compatibility, press the Windows key + X on your keyboard and select "Disk Management" from the menu that pops up. In the Disk Management window, find the disk that has your C drive (usually disk 0). Right-click on it, go to Properties, and then navigate to the Volumes tab. Look for the partition style – it should be GPT for resizable bar support. If it's MBR, resizable bar won't be supported, and enabling it could cause issues.

Enabling Resizable Bar on AMD Radeon GPUs

If your system meets the compatibility criteria, we can move on to enabling resizable bar. For AMD Radeon users, open the AMD Radeon software by right-clicking on the desktop and selecting it from the menu. Go to the Performance tab, then head over to Tuning. Scroll down and find the AMD Smart Access Memory (SAM) setting. If it's labeled as "Not Supported," we'll need to enable it in the BIOS. If it's already enabled, great! You can skip ahead to the next section.

To enable SAM in the BIOS, restart your PC and enter the BIOS settings by pressing the designated key (usually Del or F2) during the boot process. The BIOS layout may vary depending on your motherboard, but the options we're looking for should be relatively easy to find. Look for options related to resizable bar or above 4G decoding. Enable those options, save and exit the BIOS, and your PC should reboot with resizable bar support.

Enabling Resizable Bar on Nvidia GPUs

For Nvidia GPU users, we'll need to use a third-party application called Nvidia Profile Inspector to manually enable resizable bar. Start by downloading the latest version of Nvidia Profile Inspector from the GitHub page. Extract the files and run the Nvidia Profile Inspector.exe. Scroll down to find the RBar features section, and enable all three options: RBar Feature, RBar Options, and RBar Size Limit. The values should be set to "Enabled," "0x001," and "0x004," respectively. If you can't find the resizable bar features, scroll further down to the "Unknown" section and match the values accordingly.

After applying the changes in Nvidia Profile Inspector, restart your PC to ensure they are properly applied. Once your system is up and running again, resizable bar should be enabled on your Nvidia GPU.

Additional Settings for Nvidia GPUs

If the resizable bar option shows "Yes" in the Nvidia Control Panel but isn't functioning properly, we'll need to enable additional settings. Open the Nvidia Control Panel by right-clicking on the desktop and selecting it. In the top left corner, go to the dropdown menu under "Global Driver Settings" and find the Game you want to disable resizable bar for. Once you've selected the game, go to the options and set resizable bar to "Disabled." This will ensure that resizable bar is only enabled for the games you want.

If you want to reset all your Nvidia Profile Inspector settings back to default, open the profile inspector and click on the green "Reset Profile Inspector" button. This will revert all settings to their stock configurations.

Disabling Resizable Bar on Individual Games

In some cases, you might want to disable resizable bar for specific games. To do this on Nvidia GPUs, open the Nvidia Control Panel, select "Manage 3D Settings" from the left menu, and go to the "Program Settings" tab. In the dropdown, choose the game you want to modify and scroll down to find the "Resizable BAR" option. Set it to "Disabled" and click "Apply" to save the changes. This will prevent resizable bar from being used in that particular game.

Troubleshooting Tips

If you accidentally enabled resizable bar on a system that doesn't support it or are experiencing issues after enabling it, don't worry. We've got a few troubleshooting tips for you. If you're unable to boot into Windows because of an incompatible partition style (MBR), you can reset your BIOS settings by removing the motherboard's battery for 20-30 seconds. Alternatively, some systems have a CMOS reset button on the back, near the USB slots and audio ports. Use this button to reset the BIOS without having to open the case.

If you can access the BIOS but can't boot into Windows, look for an option to restore the system defaults or default settings profile in the "Save and Exit" section. This will revert all BIOS settings to their original state and should allow you to boot back into Windows successfully.

Benchmarking and Performance Improvements

Now that you've enabled resizable bar, it's time to put it to the test. Run some benchmarks and play your favorite games to see the performance improvements. Keep an eye out for reduced latency and smoother gameplay, especially in CPU-bound scenarios. Share your system specs and performance improvements in the comments below - we'd love to hear about your experiences!

Conclusion

In conclusion, enabling resizable bar on your gaming PC can unlock additional performance that is often overlooked by many gamers. By following the steps outlined in this article, you can enable resizable bar on both AMD Radeon and Nvidia GPUs and optimize your gaming experience. Remember to check for compatibility, enable resizable bar in the BIOS or Nvidia Profile Inspector, and fine-tune additional settings as needed.
