I heard the OS is what is causing this, not sure though. That's a Jaguar (Kabini) APU with an integrated GPU on-die, you have some RAM dedicated to the GPU which leaves 3.43GB is usable by the system. Same happens on Intels and AMDs with iGPUs, a certain amount of system memory has to be dedicated to the GPU for it to work since those have no VRAM like a dedicated graphics card. To simplify - there's nothing to fix or worry about, it's normal. :smile: Alright, thanks.
