dynamically allocate system memory as graphics memory, according to system and graphics
requirements. When set to “BOTH,” the graphics driver will allocate a fixed amount of memory as
dedicated graphics memory, as well as allow more system memory to be dynamically allocated
between the graphics processor and the operating system.

the BIOS assigns them automatically.
