Arc B580 101.87xx unnecessary power saving behavior

YanWK — Tue, 05 May 2026 20:52:04 GMT

Hi,

I’m connecting my display to the motherboard’s DisplayPort to conserve VRAM and dedicate the Arc B580 to AI inferencing.

However, with the newly released 101.87xx driver, the GPU appears to enter a “power-saving” state in this setup. If I connect the DisplayPort directly to the B580, performance returns to normal.

After downgrading the GPU driver to 101.8626, the issue is resolved.

OS: Windows 11 24H2
Drivers tested:

32.0.101.8737
32.0.101.8724
32.0.101.8626

Thanks.

Hello YanWK,

Thank you for raising this concern via the Intel Community.

I understand that when using the motherboard DisplayPort while dedicating the Intel® Arc™ B580 for AI inferencing, the GPU appears to enter a reduced performance or power-saving state with driver versions 32.0.101.8737 and 32.0.101.8724, while version 32.0.101.8626 works normally.

To help isolate the cause, could you please confirm the following:

Have you performed a clean driver installation using DDU before installing driver version 32.0.101.8737?
Have you checked and applied the latest Windows updates on your system before testing the newer drivers?

Additionally, to better understand your system's configuration, I kindly request that you download the Intel® System Support Utility for Windows* software.

You can find the download link here:

Download and launch SSU.exe.
Check the box for “Everything,” then uncheck Networking for your privacy.
Click "Scan."

Thanks for your advice!

After performing a clean driver installation using DDU, version 101.8737 is now working as expected. A few minor issues have also been resolved.

Hello YanWK,

Thank you for the update.

I’m glad to hear that performing a clean driver installation using DDU resolved the issue and that version 101.8737 is now working properly on your system. It’s also good to know that some of the other minor issues have improved as well.
