    Crucial Desktop Memory

    The fastest, easiest way to improve your desktop’s performance

    There’s an easy cure for a slow computer: more memory. Designed to help your system run faster and smoother, Crucial Desktop Memory is one of the easiest and most affordable ways to improve your system’s performance. Load programs faster. Increase responsiveness. Run data-intensive applications with ease, and increase your desktop’s multitasking capabilities.

    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 lots 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 desktopby giving it the resources it needs to perform.

    Micron® quality — a higher level of reliability.
    As a brand of Micron, one of the largest memory manufacturers in the world, Crucial memory represents the future of workstation and server capability. From the original DDR technology to DDR4, we've engineered the memory technologies that have powered the world's systems for 35 years and counting. Designed for leading platforms, compatible with OEM systems and warranties, and backed by a limited lifetime warranty, Crucial memory pushes the limits on performance.

      Plugged in the new chips, was alerted by my system about the ram changes, click ok, and I was up and running without incident. This is how it is supposed to be. Crucial delivered the product as advertised.

          We urgently needed memory for one of our servers. We initially wanted to purchase the memory from Crucial but figured a local distributor here in Australia could get it to us sooner. The local distributor we selected informed us they could get the memory to us in two to three days. After just over three weeks we still did not have our memory. In the end we cancelled our order with the local supplier and placed the order with Crucial on Friday afternoon. By the following Monday morning, the memory was on my desk! Two days to ship memory from continental USA to Melbourne, Australia! Plus it cost less than the local distributor! Well done Crucial!

                Ordered this kit for a Dell Precision 390 that was recently upgraded with an SSD and Windows 7 64-bit. The existing 3 gb was filling up quickly and creating performance issues. Ordered these sticks to replace two 512mb sticks and increase the memory to 6 gb. It's what this computer needed. Things are running much smoother when I have multiple programs running. Installation was simple. Remove the old sticks and install the new ones. Haven't ever had issues ordering from Crucial.

                    Added a pair of memory modules to an existing pair for a total of 8GB ECC memory so that I can have multiple memory-intensive application windows open at the same time without using the swap space. My machine is a Dell Precision T3400 with Intel Core2 Duo CPU E6550 @ 2.33GHz running Red Hat Enterprise Linux.
