Sony VPCZ21TGX Ram
The RAM in your computer stores pieces of data that the central processing unit uses for programs. Because RAM is only temporary storage for the CPU, it does not hold files like documents or pictures. But, it will impact the speed of your Sony VPCZ21TGX. The RAM speed is prescribed within the specifications from the motherboard, while the actual storage size is determined by the software. RAM is necessary for a computer to boot up. RAM is actually volatile memory as its storage is deleted when the system shuts down. If there is ever a doubt, just know that more RAM is a lot better than less RAM!
Some clues that your RAM board is going out
- You may get quite a few weird errors showing up on your laptop throughout the day
- The OS does not display the correct amount of memory installed
- The screen does not turn on when booting up
- Silence when you boot up your system
