Sony VPCSA390X Ram
Your laptop RAM stores random bits of data that the CPU is currently using for applications. RAM is actually volatile memory as all the information held gets deleted when the system shuts down. RAM is necessary even for your laptop to even boot. Due to the fact that RAM is temporary storage for the CPU, it does not have the ability to store files such as documents or pictures. But, it has a positive impact on the speed of your laptop. The clock speed of the RAM is imposed within the specs of the motherboard, while the actual storage size is dictated by the operating system. If you are unsure about the size of the RAM to buy, just know that it is impossible to have too much RAM!
Symptoms your RAM memory will need replacing
- The screen will not turn on when booting up
- You get a lot of access errors on your laptop intermittently
- The main operating system does not display the right RAM amount
- Emptiness fills the air as you try to boot up your system
