Sony VPCSB490X Ram
Having the RAM installed is mandatory even for your laptop to run at all. Your laptop RAM stores pieces of information that the CPU is currently using for programs. The RAM speed is governed by the specifications from the motherboard, and the minimum storage size is governed by the OS. Because RAM is only temporary storage for the CPU, it does not hold files like text documents or movies. But, it does have a correlation to the speed of the computer. RAM is actually temporary storage as all the data it holds gets deleted when you shut down your system. If you are ever in doubt, just know that it is impossible to have too much RAM!
Key indicators that my stick of RAM has to be replaced?
- The laptop screen will not light up when booting up
- You tend to have random errors on your laptop throughout the day
- The main operating system fails to come up with the correct amount of RAM
- Silence as you power on your system
