A-Tech 4GB DDR3 1866 ECC RDIMM 2Rx8 CL13 1.5V Server Memory

A-Tech 4GB DDR3 1866 ECC RDIMM

This registered DIMM delivers 4GB of DDR3 1866 memory with ECC error correction for server and workstation platforms. It operates at standard 1.5V voltage with CL13 latency and a 2Rx8 organisation. The module is built as a direct replacement for Micron MT18JSF51272PDZ-1G9 and MT18JSF51272PZ-1G9 parts. Each unit is tested before shipment to confirm reliable operation.

240-pin registered DDR3 build quality

The 240-pin DIMM form factor fits standard DDR3 server slots and the registered buffer reduces electrical load on the memory controller. Major-brand chips are used throughout and every module passes quality-assurance testing for dependable performance. ECC circuitry detects and corrects single-bit errors to protect data integrity in critical workloads. The 1.5V operating voltage matches the DDR3 standard for broad platform compatibility.

Upgrades Micron DDR3 1866 RDIMM modules

This module replaces Micron MT18JSF51272PDZ-1G9 and MT18JSF51272PZ-1G9 sticks when a compatible 4GB DDR3 1866 registered ECC DIMM is required. The jump is worthwhile when a system needs registered ECC memory at this speed and density to maintain stability under sustained load. Buyers who need unbuffered UDIMMs, higher capacities per module, or a different DDR generation should verify their platform requirements before ordering.
