Question How to release reserved RAM from 2400g integrated Vega GPU?

[ketrab]

I've got a unit (HP Pavilion Gaming) that came with dedicated GPU. Upon checking resource I see that 2GB is "reserved" for the Vega which will never be used.
I'm not familiar with HP BIOS so I thought I'll ask in the AMD community on proper disabling the Vega to have RAM released.
Only option in bios under PCI Graphic Configuration gives two options that are NOT clear to me. See below. Any advise would be greatly appreciated.

Check Device Options.

That is laptop. Right?
On laptop you will not be able to disable integrated graphics. But you may be able to reduce amount of ram reserved for integrated graphics.

Your assumption that it will never be used is false: anytime your PC is displaying something on the screen, memory is being used by your GPU (whether integrated or discrete) to display that information. There is no option to disable this as it would prevent your PC from functioning properly.

If having less RAM than you anticipated for the rest of your PC is causing you issues, you can always buy more RAM for your system.

if i'm using dedicated there is no point of integrated to be used and reserving ram. Throwing hardware at the problem is not the solution but last resort.

It was not made clear in your original post that you are using a dedicated GPU. If I had known, my advice would have been different.

Oops, I missed that somehow. My bad.

If you leave VGA to auto, the IGP and its memory reservation should be automatically disabled when a dGPU is present and no monitor is connected to the IGP. At least that's how most motherboards seem to be handling it.

Only option in the bios is the one attached. Not much of help from HP :/
