Hi. Last week I inserted a stick of 2GB RAM in my computer, now I have 2x2GB DDR3. In Control Panel > System it says 4GB installed, but only 2,25GB can be used, and in Task Manager it says 1,8GB hardware reserved.

My motherboard is a Gigabyte GA-EP35C-DS3R. I checked BIOS but I didn't saw an option to allocate more memory (check manual). This motherboard full supports 4GB DDR3.

I have a GeForce GT 1030, so isn't a integrated graphic card. 2GB dedicated memory and 1GB shared memory. Drivers are up to date and I deleted old GPU drivers.

System is Windows 8.1 x64. I already tried to disable the maximum memory in msconfig but the problem persist.
