Request to Enable Resizable BAR (ReBAR) Support for HP Laptop AI 15-fd2116TU (D4QU6PA)

[irfan55]

Hello HP Support,

I am using an HP Laptop AI 15-fd2116TU (D4QU6PA). Intel Graphics Software reports "ReBAR Support Available", but there is no Resizable BAR option in the BIOS.

I would like to enable Resizable BAR because it can improve compatibility and graphics performance in supported games, including EA SPORTS FC 25. Could you please confirm whether this model supports Resizable BAR, and whether there is a BIOS update or official method to enable it?

Thank you.

Even if it support. It can be disabled. It’s the same on many laptops. These kinds of options are usually configurable on PCs, but for compatibility reasons, manufacturers especially on laptops may leave them off by default in hidden firmware settings. In most games, enabling it only provides around 0–5% improvement, or sometimes a barely noticeable change. There might also unofficial tricks online that may give access to more BIOS settings, but they are not safe and there is no guarantee they will work. They can make the system unstable or worse. So it’s better to accept the fact that you are on a laptop and that the option is not available. This ReBAR feature also has some downsides, and the performance gain is usually small. A few games may benefit a little more, but it’s not something to worry about too much. It’s not a big deal. 

If you want to improve gaming performance and smoothness then many good windows optimization and GPU software settings available configuring them correctly and setting game graphics settings is best you can do. Just make sure to choose good and safe optimization guide, as some can be too intensive and break some features. 

By the way, there is utility called "GPU-Z", you can download and install it from browser and it can show rebar status. But remember what said above, you can do anything if it's disabled and it doesn't make big difference.
