Protip if you want to squeeze most out of your VRAM if you have a CPU with iGPU

If you want to reclaim couple hundred MB of VRAM, enable iGPU in bios and plug in the display cable to motherboard, that way iGPU handles the system and frees up the memory of dedicated GPU entirely.
This is especially useful for those of you who run Windows or non-server Linux with GUI.

Hope that helps!
