Micron MT18JSF51272PKZ-1G4 4GB DDR3-1333MHz Mini-RDIMM 2Rx8 CL9 Memory

Product Description

The Micron MT18JSF51272PKZ-1G4 is a high-quality 4GB DDR3 Synchronous Dynamic Random-Access Memory (SDRAM) module designed for demanding server and workstation environments. Operating at a speed of 1333MHz, which corresponds to a PC3-10600R designation, this module provides efficient data transfer rates crucial for multitasking and intensive applications. The 'R' in PC3-10600R signifies that it is a Registered DIMM (RDIMM), which includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in systems with many memory modules. This specific module is configured as 2Rx8, meaning it is dual-rank with an eight-bit data width per rank. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to access different ranks of memory more efficiently. The CAS Latency (CL) is rated at 9, indicating the number of clock cycles required to access data after a command is issued. This CL9 timing, combined with the 1333MHz speed, provides a balanced performance profile suitable for a wide range of server workloads. The module operates at a standard voltage of 1.5V. Furthermore, the MT18JSF51272PKZ-1G4 supports Error-Correcting Code (ECC) functionality. ECC memory is essential in server environments as it can detect and correct common types of internal data corruption, thereby enhancing data integrity and system reliability. This makes the module an ideal choice for mission-critical applications where data accuracy and uptime are paramount. Its Mini-RDIMM form factor is a smaller variant of standard RDIMMs, often used in specific server or embedded system designs where space is a constraint.
