Micron MT18JSF51272AKZ-1G4D1 4GB DDR3-1333MHz Mini-UDIMM 2Rx8 Memory

Product Description

This 4GB DDR3 Mini-UDIMM from Micron, identified by SKU MT18JSF51272AKZ-1G4D1, is a compact memory module designed for systems where space is a constraint, such as small form factor PCs, some workstations, or specialized embedded systems. It utilizes the Unbuffered DIMM (UDIMM) architecture, which means it does not have a register chip, placing a direct load on the memory controller. This is typically suitable for systems with fewer memory modules per channel. The module operates at a frequency of 1333MHz, providing adequate performance for general computing tasks and moderate workloads. The 2Rx8 rank configuration indicates two ranks of memory chips, each with an 8-bit data width, contributing to the module's 4GB capacity. The CAS Latency (CL) of 9 is a standard timing parameter for DDR3 memory at this speed. The primary advantage of this module is its Mini-UDIMM form factor, which allows it to fit into systems with limited internal space. Unlike RDIMMs, UDIMMs do not have the register chip, making them simpler and often less expensive, but also limiting the total memory capacity achievable in a system. This module is suitable for applications that do not require ECC error correction and are designed for smaller chassis. The MT18JSF51272AKZ-1G4D1 is a practical choice for upgrading or populating memory in compact systems where standard DIMMs might not fit.
