Sony VPCZ21AGX Ram
The RAM speed is imposed within the specifications from the motherboard, and the minimum storage size is dictated by the OS. Due to the fact that RAM is temporary storage for the CPU, it does not have the ability to store files such as text documents or movies. But, it has more to do with the speed of your Sony VPCZ21AGX. RAM is considered volatile memory as its storage is erased when you shut down your system. Some RAM is mandatory for your laptop to run correctly. Your laptop RAM stores random bits of data that the processor uses for executing commands. If you are ever in doubt, just know that more RAM is a lot better than less RAM!
Simple indications of a declining RAM board
- The OS does not report the correct RAM amount
- Nothing happens when you initiate your laptop
- You may get quite a few random reboots on your laptop throughout the day
- The screen does not light up when you turn your system on
