Sony VGN-Z720Y Ram
RAM is actually volatile memory as the data it holds is erased when you shut down your system. The clock speed of the RAM is governed by the specifications from the motherboard, while the size is governed by the OS. Your laptop RAM stores random bits of data that the CPU is currently using for applications. Having the RAM installed is mandatory in order for the Sony VGN-Z720Y to run correctly. Due to the fact that RAM is temporary storage for the processor, it does not hold files like programs or emails. But, it does have a correlation to the speed of your Sony VGN-Z720Y. If you are unsure about the size of the RAM to buy, just know that more RAM is a lot better than less RAM!
Hints of a bad RAM board
- Silence when trying to boot up your laptop
- You get a lot of random errors on your laptop as you use it
- The OS cannot report the right amount of RAM as it should
- The laptop screen will not turn on when starting up
