Sony PCG-F690K Ram
Some RAM is mandatory in order for the Sony PCG-F690K to run at all. The RAM speed is dictated by the specs of the motherboard, while the size is dictated by the software. RAM is a type of volatile memory as all the information held gets deleted when you shut down your system. 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 more to do with the overall speed and quickness of your Sony. RAM stores random bits of information that the computer uses for programs. If there is ever a doubt, just know that it is impossible to have too much RAM!
What symptoms are present when the stick of RAM is dying?
- The screen does not display anything when you start your laptop
- The OS does not display the correct memory size
- You may get quite a few invalid access errors on your laptop throughout the day
- Nothing happens as you try to initiate your system
