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.

Maximize memory performance and get more out of your servers
Memory-dependent server applications are often inhibited by RDIMM channel ranking limitations. Crucial LRDIMMs solve this problem by utilizing a memory buffer chip that reduces electrical loads presented to the memory bus, allowing more DIMMs to be populated per channel. The result? Increased memory bandwidth, improved energy efficiency, and greater memory density compared to standard RDIMMs.
Increase memory bandwidth and performance
Since Crucial LRDIMMs are engineered to reduce electrical loads presented to the CPU, they enable more installed DIMMs per channel for greater memory density. With more memory density and reduced electrical loads, servers are able to run Crucial LRDIMMs at a greater frequency for more memory bandwidth.
Increase energy efficiency and lower your TCO
Crucial LRDIMMs transmit power in a more efficient manner to the CPU – via the data path buffer – allowing for additional power savings and a lower total cost of ownership. Plus, Crucial LRDIMMs are backed by the Reliance Program* and a limited lifetime warranty to further minimize your TCO.
Increase the performance of demanding server applications
For memory-dependent server applications such as hyperscale computing, virtualization, cloud computing, Big Data, and more, you’ll be hard-pressed to find a more cost-effective performance solution. Because Crucial LRDIMMs enable dramatic performance gains, they’re the smart way to increase memory bandwidth and capacity.
Available in the latest technology
Built with new technology tailored for the latest Intel platforms, Crucial DDR4 LRDIMMs allow you to increase system performance with memory speeds up to 2666 MT/s and densities up to 64GB. Increasing the installed memory capacity of each server with modules equipped with 8Gb-based components enables your systems to reach their full performance potential.
Backed by the Reliance Program*
When you make an enterprise-level investment in Crucial products, we believe you deserve a higher level of support. The Reliance Program offers qualified customers up to four additional benefits that affirm our commitment to your servers through service call reimbursements, on-site spares, 24/7 technical support through our direct hotline, and special bulk shipping options.
