Can not enable Resizeable Bar (A750)

[Bobuka]

HI! I'm from Vietnam. Please help!

I enabled Resizeable Bar in BIos but It is still disabled when I enter GPU Z or intel Arc control.

I am using 11400f
 Asus Ex B560M V5
Arc A750

Hello Bobuka,

Thank you for posting on the Intel communities. Given that you are experiencing difficulties enabling the Resizable Bar for the Intel® Arc™ A750 Graphics, kindly respond to the following inquiries so that we can better understand the circumstances:

• Is the graphics card an Intel Branded Card or is it of another brand?
• Take a screenshot of the BIOS settings showing if Resizable Bar is enabled.
• To know your system environment, run, save, and attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.

Hello Bobuka,

Thank you for your response and clarification.

I checked the Intel® SSU and I see your system is up to date, please answer the following question to know if the graphics driver was properly installed, and also to improve the compatibility and stability:

• Did you run the Display Driver Uninstaller (DDU) before installing the driver 31.0.101.5084? Otherwise, follow the article How to Use the Display Driver Uninstaller (DDU) to Uninstall an Intel® Graphics Driver and then install the driver 31.0.101.5084.

Keep me informed of the results.

Hi Andres! 

Thank you for your reply. I have tried and it still hasn't fixed the issue.

Is it possible that because I couldn't turn off CSM as I mentioned above?

Hello Bobuka,

Thank you for completing the steps.

Since you are not able to disable it could be the reason, but just to verify that, I will start with an investigation to provide you with more details as soon as possible.

Hello Bobuka,

Thank you for your time.

I have been working on the investigation and now I have the following questions:

• Was this working properly before? If so, what changed?
• Were there any updates to the BIOS, did this happen after the update?
• Did you notice any changes in performance issues when Resizable Bar is reported as not being enabled?

Hello!

• I haven't been able to enable Rebar since I got this GPU.
• Yes, I've updated the BIOS, but even before the BIOS update, I couldn't enable Rebar. However, I was able to turn off CSM before updating the BIOS.
• The gaming performance is quite poor. That's why I want to be able to enable it.

Hello Bobuka,

I will continue with the investigation to provide you with the next steps as soon as possible.

Hello Bobuka,

Thank you for your time.

I have been working on the investigation and I want to let you know that most platforms (motherboards) require CSM to be disabled in order to enable Resizable BAR. This should not be dependent on the graphics card installed so we suggest reporting this to the motherboard manufacturer.

For now, we will close this thread. If you need any additional information, please submit a new question as this thread will no longer be monitored.
