Crucial 128GB (4x 32GB) 288-Pin LRDIMM DDR4 (PC4-17000) Server Memory Module Kit, CL=15, QR x4, Load Reduced, 2133 MT/S Speed, ECC, 1.2V, 4096 Megx72

Maximize memory performance and get more out of your servers
Memory-dependant 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 higher frequency, enabling up to 50 percent more memory bandwidth.

Increase energy efficiency and lower your TCO
Not only do Crucial LRDIMMs use less voltage and standby current, but they 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.

Increase the performance of demanding server applications
For memory-dependant server applications such as virtualization, cloud computing, in-memory databases, Big Data, HPC 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, while also reducing power expenses.

Compatible with OEM systems and warranties
Crucial LRDIMMs are Intel validated, compatible with OEM servers and warranties and backed by a limited lifetime warranty.2 Now available for cutting-edge DDR4 server platforms, Crucial DDR4 LRDIMMs are optimized for future Intel Xeon processor E5-2600/1600 v3 product families, allowing you to maximize next-generation deployments.

Features
• 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.
