Key Features and Benefits:

• Make everything on your computer faster
  Memory is a component in your computer that allows for short-term data access. Since your system's moment-to-moment operations rely on short-term data access - loading applications, browsing the Web or editing a spreadsheet - the speed and amount of memory in your system plays a critical role. Load apps in seconds by increasing the speed of your memory and installing more of it.
• Multitask with ease
  Use your computer to do a lot of things at once. You might be editing a document, while also looking at pictures and browsing the Internet. This naturally leads to a performance problem: every app you're running requires memory and competes for a limited pool of resources. Overcome this by installing high-density modules in each memory slot for seamless multitasking.
• Install with ease - no computer skills required
  With just a screwdriver, your owner's manual, and a few minutes of time, you can install memory - no computer skills necessary.
• Maximize the value of your system
  At a fraction of the cost of a new system, a memory upgrade is one of the most affordable ways to increase performance. Get more out of your desktop by giving it the resources it needs to perform.
