There may be times when you notice that your computer is not performing as efficiently as it should. Programs seem to be opening more slowly than normal and sometimes your computer may lag when in use. When this happens, it may be time to add more memory or RAM to optimize performance.
RAM is not difficult to install. However, if you are not handy with upgrading memory by yourself, you may need to have a qualified computer technician do this for you. RAM is installed in a space specifically designed to accept RAM modules. This section is usually located close to the processor and can be replaced by removing lower capacity modules and replacing with higher capacity RAM. You could also just be adding additional modules to increase RAM capacity
Depending on the type of operating system you have installed on your computer, your choice of RAM may be limited. If your system is a 32-bit operating system with 4GB of RAM installed you'll only be able to access around 3.2GB. However, with a 64-bit operating system you'll typically have full access to the whole 4GB or more if you have more RAM installed. Be guided by the notion that all 32-bit versions of Windows 10 have a 4GB RAM limit. The 64-bit version accesses RAM above 4GB, usually up to 32GB.
If you want to use your computer for gaming, you will want to be using at least a 64-bit operating system. You will also want to get the most RAM you can, and this should typically be more than 4GB. At a minimum, 4GB will get your system going for gaming. However, to avoid performance of speed-related issues, it is recommented for modern gaming applications to have 8GB of RAM. In some instances 16GB of RAM may be necessary but 8GB may be enough RAM for your gaming application.
