Closed Not all RAM usable Tags: Memory Laptops Acer RAM Windows 8 Last response: January 25, 2013 5:08 AM in Memory Share mathiascali January 25, 2013 4:56:33 AM Just bought a new Acer laptop running windows 8 64 bit with 6 GB of RAM installed. Windows is saying only 5.82 GB is usable. How can I fix this? I checked the BIOS and found nothing related to RAM. Thanks.

If so the system is using RAM from your "6GB" to serve as video memory. This is perfectly normal and can be set to smaller or greater values in your BIOS with most laptops. | Report abuse mathiascali January 25, 2013 5:06:37 AM Yes, it has Intel HD 4000 graphics. I suppose this must be it.
