Hello,
I cannot find where to change the size of allocated memory to my Ryzen 2400G.
The default is 512 MB, I would like to increase to 2 GB.
Thanks for helping me.

Regarding your question about allocated memory, please follow below path to modify:

Step 1: Please press hotkey [Delete] during POST to get into BIOS
Step 2: Advanced\AMD CBS\NBIO Common Options\GFX Configuration\Integrated Graphic Controller\Forces
