Hi everybody,
I'm using the CPU A12 9800 on AB350 asrock fatality itx/ac. I want to share more ram to my iGPU (512MB as default) up to 2 or 3GB (I'm using 16GB ram) but I cannot find the Graphic configuration or something like that in the BIOS... Could somebody please help me with the BIOS or I can use any software to do so? Tks in advance

Oh, 2GB is the Max you can select. There is no app that can change that Max either, FYI.

Have you checked in GPUz to see how much RAM is being shared in OS? It could be set dynamically like it has been in the past on some platforms. If it is dynamic the amount of vRAM should be listed in GPUz as the maximum supported by the platform (2gb?) if not, try running the GPUz fur test and see if it increases.
If not, I will look into it with ASRock
