Crucial 2GB 240-Pin UDIMM DDR3 (PC3-12800) Server Memory Module, CL=11, Unbuffered, 1600 MT/S Speed, Non-ECC, 1.5V, 256Meg x 64

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 them 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 Crucial Technology three-minute install videos and they will 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, Crucial Technology have 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.

Memory spec terms
If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.

NON-ECC/Non-parity
Most desktop and laptop computers take NON-ECC or Non-parity memory.

ECC/Parity
ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.

Unbuffered
Most PCs and workstations use unbuffered memory which is faster than registered memory.

Registered/Buffered
Registered or buffered modules delay all information transferred to the module by one clock cycle. This type of memory is primarily used in servers.

Fully buffered
Designed for next-generation servers, features an advanced memory buffer.

CL
CAS (column address strobe) latency, which is the number of clock cycles it takes before data starts to flow after a command is received. Lower CL is faster. Modules with different CL can be mixed on a system, but the system will only run at the highest (slowest) CL.

Component configuration
(For example: 64Meg x 64) Indicates the size of the memory chip components on the module.

Voltage
For example 2.6V. Indicates the power used by the module. The lower the better.
