Micron MT18JSF51272PZ-1G9 4GB DDR3-1866MHz RDIMM 1Rx4 CL13 Memory

Product Description

The Micron MT18JSF51272PZ-1G9 is a 4GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module specifically designed for server applications. It operates at a frequency of 1866MHz, corresponding to a PC3-14900 designation, offering a good balance of speed and capacity for many enterprise workloads. The module utilizes a 1Rx4 rank configuration, meaning it has a single rank with four data bits per memory chip, which is common in server memory modules. As a Registered DIMM (RDIMM), this memory module incorporates an onboard register chip that buffers the command and address signals sent from the memory controller. This buffering reduces the electrical load on the controller, allowing for more memory modules to be installed in a system and enhancing overall stability, which is critical for server uptime. It also supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors and detects multi-bit errors, thereby improving data integrity and system reliability. With a CAS Latency (CL) of 13, the MT18JSF51272PZ-1G9 provides efficient timing for memory operations. This 4GB DDR3 RDIMM is a suitable choice for upgrading or populating memory in servers that require reliable and stable performance for tasks such as virtualization, database management, and application hosting.
