GPU memory allocation must be configured manually in EFI
Reboot the EVO-X2 and press Esc to enter BIOS. Go to Advanced → GFX Configuration. Set iGPU Configuration → UMA_SPECIFIED. Set UMA Frame Buffer Size to the desired value, e.g. 96G on the 128GB model. Press F10 → Save & Exit. With 128GB RAM, a 96GB UMA allocation provides approximately 96GB of GPU VRAM and leaves approximately 32GB for system RAM.
