Okay, so I own a Asus K55N that has 6GB of ram that is shared. When I first bought this laptop I changed the shared ram to give the CPU 5.5GB and the other 0.5GB to the GPU. I want to change this back to factory which I believe was 4GB to CPU and 2GB to the GPU. Unfortantly I forgot how to do this exactly, I still know how to enter the bios which is F2 during boot, but after that I am lost and I wasn't able to figure anything out on how to change the ram usage. I tried resetting the bios back to default but when i got back into Windows the ram was still 5.5 at the CPU.
