Memory Modules

The Random Access Memory (RAM) is an important part of computers, servers and other electronic devices. Generally it is much faster than the permanent storage memory of your device and all information stored in it will be lost when you switch off your device. Extra RAM is often an affordable and efficient way to upgrade your slightly outdated device, so you can use it another year.
