I have a toshiba satellite L455D-S5976 and it is 2 gb ddr2. Ok, I have installed it a 4 gb ddr2 ram but, when I check the system info it says: Memory: 2.8 GiB. I don't know if that number is refering to the RAM quantity, but I want to know if I have done rigth the process? I can use my computer normally, but I don't know either if it have to make something different or be more fast, dunno.
Any answers are welcome.
