A-Tech 4GB DDR3 1866 ECC RDIMM 1Rx8 server RAM

Server Memory Upgrade

This 4GB DDR3 ECC RDIMM replaces Micron MT9JSF51272PZ modules in compatible server and workstation platforms. The registered design adds a buffer between the memory controller and DRAM for signal integrity in multi-module configurations. CL13 latency at 1866MHz provides standard DDR3 throughput for supported systems. All modules undergo quality assurance testing before shipment.

Registered ECC Functionality

Error-correcting code detects and corrects single-bit data errors that can corrupt critical workloads. The registered buffer reduces electrical load on the memory bus, allowing larger memory populations than unbuffered alternatives. Operation at 1.5V matches standard DDR3 voltage requirements for supported platforms. Compatibility must be verified against the system's qualified vendor list before installation.

4GB Capacity Boundaries

A single 4GB module suits light virtualization, legacy database instances, or file-serving roles with modest working sets. The 1Rx8 organisation fits one rank per channel, leaving additional DIMM slots available for expansion where the platform permits. Workloads requiring large in-memory datasets or dense virtual machine consolidation will exceed this capacity quickly. DDR3 architecture limits further upgrades to the same generation.
