my toshiba satellite notebook can accept up to 4gb ram. So i bought 2x2gb. When i install both ram cards the windows doesnt starts. when i install only one ram card then it works fine. When i install both in bios setup display me that there are only 3gb ram and not 4. The cards and slots are ok., i m sure about that. Any help?

Jump to PostUnfortunately, 32 bit machines can only handle up to 3 gigs of mem. <approximately> Oh, well.
Jump to PostThe range of integer values that can be stored in 32 bits is 0 through 4,294,967,295 or −2,147,483,648 through 2,147,483,647 using two's complement encoding. Hence, a processor with 32-bit memory addresses can directly access 4 GB of byte-addressable memory. Some of the 4 gigs is reserved.
