Resizable BAR BIOS upgrade

[winabbey]

I have an EliteDesk 800 G8 SFF PC with HP 889C motherboard and Intel UHD Graphics 750 display board, all as delivered from HP, now running Windows 11.

Intel support assistant has alerted me to a possible update to the graphics driver and says resizable BAR is required for optimal performance and a BIOS update may be needed (see screenshot below).

How do I check if a BIOS update is needed and where do I get this update?

Hi

The latest BIOS update for your PC https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-elitedesk-800-g8-small-form-factor-pc/... does not list a Resizable Bar option in the fixes section.

Eleventh gen Intel CPUs support Resizable Bar when paired with a Resizable Bar/ Above 4G decoding option in the BIOS and recent Nvidia, AMD, and the latest  Intel Arc Desktop and Mobil GPUs https://www.intel.com/content/www/us/en/products/details/discrete-gpus/arc.html .

I don't believe the integrated Intel UHD Graphics 750 support Resizable Bar.

Many thanks Bill_To - I will ignore the update offered.
