4GB DDR3 1600MHz ECC RDIMM for Server Upgrades

This 4GB DDR3 1600MHz ECC registered DIMM uses a 2Rx8 organisation and runs at the standard 1.5V. It is built as a direct replacement for Micron part numbers MT18JDF51272PDZ-1G6 and MT18JSF51272PDZ-1G6. The module fits 240-pin DIMM slots in servers and workstations that require registered ECC memory.

Replaces Micron MT18JDF51272PDZ-1G6

The kit matches the original Micron specifications for speed, voltage, rank structure and ECC behaviour. Swapping in this module restores the rated PC3-12800 throughput and registered buffering without changing platform settings. The upgrade is worthwhile when a failed stick must be replaced or when empty registered DIMM slots are available for capacity expansion.

Suits Servers and Workstations Requiring

This module suits administrators maintaining systems that specifically call for DDR3 1600MHz registered ECC memory in a 2Rx8 4GB configuration. It is not suitable for platforms that accept only unbuffered UDIMMs, require a different voltage, or need higher-density modules than 4GB per slot.

Questions about this item

Does this 240-pin DDR3 DIMM fit a standard server memory slot?

Yes, the module uses the 240-pin DDR3 DIMM form factor that matches standard registered server slots.

What BIOS setting or step is often missed when installing this registered ECC module?

The system must support registered ECC memory; some platforms require enabling ECC in the BIOS before the module will be recognised.

Will the 1.5 V DDR3 chips need replacement under normal server workloads?

The module uses major-brand chips tested for reliability and is covered by a lifetime warranty, so no scheduled replacement is expected.
