Need help selecting a memory upgrade?
The more RAM you have installed in your computer, the more applications you can run without slowing down the system. For example, if you are installing a 2GB upgrade, it will allow for a greater potential performance increase in comparison to installing a 1GB or 512MB upgrade. If you are running applications on your computer that like to take advantage of the RAM installed, such as photo or video editing applications, it is a case of the more RAM installed the better the application will perform.
The operating system (or OS) your computer has installed also has a maximum RAM limit. The most common OS, Microsoft Windows generally ships as a 32-bit version. The downfall of a 32-bit OS is when more than 4GB of RAM is installed; the OS will read between 3.0GB to 3.6GB depending on the hardware installed in your computer. If your system has a maximum memory limit of 4GB or higher, we recommend you use 64-bit OS on your system.
Installing memory in your computer is classified by most manufacturers as a Do It Yourself (DIY) upgrade. The Upgradeable Memory Installation Guide is included with every order which is to be used with your computers owner's manual. A PDF copy of the guide is available for download
here. We provide tech support over the phone in case you require any further assistance performing the memory upgrade procedure.
A majority of computers sold do not require pairs to be installed. Where computers have Dual or Triple channel technology, installing memory in pairs will see a slight improvement in performance. With some computers, pairs can be a requirement, check your system configuration details table for more information.
