Server memory upgrade

This 4GB DDR3 1333MHz ECC registered DIMM is built for server and workstation platforms that require error-correcting registered memory. It operates at 1.5V standard voltage with CL9 latency and uses a 2Rx8 rank configuration on Micron chipset. The module is a compatible replacement for Micron MT18JSF51272PDZ-1G4D1DD and MT18JDF51272PDZ-1G4D1AD part numbers.

Replaces specific Micron modules

It directly substitutes the listed Micron 4GB DDR3 1333MHz ECC RDIMM parts when a matching capacity, speed, voltage and registered ECC specification are required. The upgrade is worthwhile when your system documentation confirms support for 2Rx8 registered DIMMs at PC3-10600 speed and you need to replace a failed module or add capacity within the same memory channel configuration.

Verify platform requirements first

Before ordering, confirm that your server or workstation motherboard accepts DDR3 240-pin registered ECC DIMMs at 1333MHz with 1.5V operation and 2Rx8 organisation. Check the system manual or vendor memory-qualified list for maximum module capacity per slot, total supported memory and whether mixed-rank populations are allowed. This module is not suitable for platforms that require unbuffered non-ECC memory or a different DDR generation.

Questions about this item

Will the 240-pin DDR3 DIMM fit my server's memory slots?

Yes, this module uses the standard 240-pin DDR3 DIMM form factor required by compatible server and workstation motherboards.

What is the correct way to seat this registered ECC module so the system recognises it?

Align the notch with the slot key, press firmly until both side clips click shut, and ensure all modules match in speed and rank for the memory controller to initialise correctly.

When should I expect to replace this 4GB DDR3 RDIMM?

DDR3 server memory has no scheduled replacement interval; swap it only if diagnostics report correctable ECC errors rising or the module fails memory testing.
