I have a HP Pavilion dv6-7000-sy laptop. It's about 5-6 years old now. It has a nvidia geforce 630m 2GB grpahics card. Laptop itself has 6GB ram installed, but with some investication it seems that 2gb of ram is reserved for the graphics card. It has a 4gb and 2gb ram installed. It has gotten very slow on booting and overall usage, it seems that its running out of ram, as in even when idel its using ~50% of the ram it has. I want to upgrade to larger rams, as it might help the situaton, but after seeing the setup, can i even upgrade both of the rams, or can i upgrade only 1 of the rams.
