Microserver Gen10 Plus v2 Resizable BAR

[Vhaelan]

I'm planning to buy an Intel Arc Pro A40 GPU for my G10+v2 microserver. Can you advise where I can turn on the Resizeable BAR support, which is required for these Intel cards? https://www.intel.com/content/www/us/en/support/articles/000090831/graphics.html

On the ProLiant MicroServer Gen10 Plus v2, Resizable BAR support is controlled via BIOS settings. However, HPE servers often lack direct user-configurable options for ReBAR because they are primarily designed for enterprise workloads rather than gaming or workstation GPUs.

Does your response mean this function is not available? There are very limited options in terms of half height GPUs. Where do I find the list of supported GPUs if resizable BAR is not available?

@Vhaelan 

From what I know about the HPE ProLiant MicroServer Gen10 Plus v2, Resizable BAR  support is not explicitly listed in any official BIOS documentation. That said, HPE servers typically do not focus on gaming- or workstation-grade GPU features like ReBAR, which is required for optimal Intel Arc performance.

However, you can check with support team for the exact information

Any updates on this? New Intel cards for server and workstation need rebar.
