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.

Increase the performance of your servers
Buying new servers is expensive. Getting more out of your current infrastructure isn’t.
Maximizing a server’s installed memory capacity with Crucial RDIMMs is one of the easiest and most affordable ways to make your deployments faster and more efficient. Crucial RDIMMs contain a register chip, which directs data commands and helps control the flow of data within the server. By virtue of the register chip, Crucial RDIMMs have ECC parity, which helps prevent data errors and increases overall system reliability.
Speed up server applications
By installing Crucial RDIMMs, you’ll be able to maximize the performance capability of your CPUs and optimize your servers’ computing potential. Since memory typically functions as a fixed (non-shared) component, it’s often a bigger performance constraint than processors or storage drives, which can be shared. Maximize your investment in server infrastructure by maximizing memory capacity.
Get more out of your IT budget
At a fraction of the cost of new servers, Crucial RDIMMs allow you to extend the life and performance of your existing infrastructure and get more out of the rack space you already have. Even if you need to replace existing deployments, you can still save by buying servers with the least amount of preinstalled memory, then maximizing the installed memory capacity with Crucial RDIMMs.
Compatible with OEM servers and warranties
Similar to how you can upgrade a server’s preinstalled components and choose whichever brands you want, you can do the same with memory – without having to worry about voiding your manufacturer’s warranty. In terms of system compatibility, Crucial RDIMMs are optimized for the latest Intel® Xeon® processor product families and 100% component and module tested.
Run more virtual machines and increase the responsiveness of virtualized applications
Since most of today’s enterprise applications are stored on servers and distributed to a number of virtual machines, the amount of installed server memory plays a more critical role than ever before. Every virtual machine running on a server typically requires a dedicated amount of memory, meaning the more virtual machines you’re running, the more memory you’ll need.
Available in the latest technology
Built with new technology tailored for the latest Intel platforms, Crucial DDR4 RDIMMs allow you to increase system performance with memory speeds up to 2666 MT/s and densities up to 32GB. Increasing the installed memory capacity of each server with modules equipped with 8Gb-based components enables your systems to reach their full performance potential – especially without rank limitations.
