    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 desktop by 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.

    I wanted to upgrade my PC but not being a technician, was at a loss as to what memory would run with the current one. Having had a look at the usual websites I was presented with all sorts of technical terms like ECC and non buffered, DDR2, DDR, DDR3 etc, and I was reluctant to order something that might not work on my PC. So I was pleasantly surprised when I visited the Crucial.com website and downloaded a small program that checked my PC and not only identified the exact motherboard but even the fact that I had a spare slot to insert additional memory. It then identified the exact type of memory that would suit my PC. All this without even having to open my PC case!The ordering process on the Crucial website was a breeze and the whole process took me only 5 minutes. [...] I was able to insert it onto the motherboard within 10 minutes and everything is working fine and there are no compatibility issues. My PC is running a lot smoother and faster now with the additional ram and the best bit was that the memory I ordered was reasonably priced too. Full marks to Crucial for a fantastic service, I will not only order from them again but also recommend them to all of my friends and relatives.

    After installing the memory and switching the PC on, all we got was beeping sound from the PC. Tried different permutation of the memory but same result. Contacted Crucial technical support who suggested I try single memory module at a time. This identified one of the memory modules in the kit to be faulty.

          I searched the internet in order to upgrade my HP Compaq, I found many outlets but this company offered to check my system and recommend the best product for me. After doing a comparison on prices this site was the best by far. Having received the memory upgrade it took only five minutes to install and once this was done the change in the computer was amazing. I will be looking to purchase more from this site in the future. In summary excellent.
