I have a Toshiba Satelite C650 (PSC12C-00M00S) with Core i3. Previously it came with 4 GB RAM. It had previously 2GB + 2GB. What I did, I bought two 4GB RAM modules and replaced them with these two. I have Windows 7 Professional 64 Bit; But the problem is it is still showing 4GB in the System Properties. I did check the RAM slots, but they seem to be fine. What may be the problem? Any Solution? Here is the of screenshot of my System Information.
