How to change DVMT Pre-allocated outside the BIOS?

Question asked by kevin59 on Jul 20, 2019

My laptop is configured by default with 2.1 Gb of RAM dedicated to the integrated GPU.

This is too much because the CPU can use only 5.9 Gb despite 8 Mb of installed RAM.

I understand that the corresponding setting is normally in the BIOS (DVMT Pre-allocated in Graphics Configuration in the Advanced tab).

Unfortunately, there is no such option in my BIOS.

Anybody knows how to change this setting outside of the BIOS ?

 

Configuration: Asus X512DA, CPU Ryzen 5 3500U with Radeon Vega Graphics 8 (integrated GPU), RAM: 8 Gb, no graphic board, windows 10 version 1903, BIOS : American Megatrends 302 (see DxDiag report attached)

 

I have seen this problem (too much memory dedicated to the GPU) on several ASUS laptops all with an AMD APU, none with an Intel APU.
