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

If you’re like us, you 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. Just watch one of our three-minute install videos, and we’ll walk you step-by-step through the process. Don’t pay a computer shop to do something you can do in minutes!

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 laptop by giving it the resources it needs to perform.
