Sony VGN-TZ191N Ram
Because RAM is only temporary storage for the CPU, it does not hold files like programs or emails. But, it does have a correlation to the speed of the computer. The speed of the RAM is predetermined through the specifications from the motherboard, while the size is determined by the operating system. Some RAM is mandatory even for your laptop to run at all. RAM is actually volatile memory as its storage is deleted when the system shuts down. The RAM in your computer stores random bits of information that the central processing unit uses for applications. If there is ever a doubt, remember that bigger is always better!
How do you know when your RAM stick is about to fail?
- Silence as you try to start your system
- The OS produces invalid access errors on your laptop throughout the day
- The system does not show the correct memory size
- The main screen does not display correctly when you start your laptop
