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.

이 상품에 대한 질문
Will the 1Rx8 registered ECC DDR3 module need any firmware updates or battery replacements during its service life?
No firmware updates or battery replacements are required for this 1Rx8 registered ECC DDR3 module; it is a passive component that operates without firmware or onboard power storage.
What limit appears first when the 1866 MHz DDR3 RDIMM runs at full load for extended periods?
The primary limit under sustained full load is thermal — the DDR3 chips and register can reach their maximum safe operating temperature, which may trigger throttling or instability if chassis airflow is insufficient.
How much power does the 1.5 V DDR3 registered DIMM draw and how loud is it when the server runs all day?
The 1.5 V DDR3 registered DIMM draws only a few watts and produces no audible noise; any sound comes from system fans responding to the module's heat output.
