Server memory upgrade

This 16 GB DDR4 module runs at 2133 MHz with a CAS latency of 15 and operates at 1.2 V. It uses a 288-pin RDIMM form factor with ECC and registered buffering for error correction in multi-socket environments.

Suited for DDR4 servers and workstations

The dual-rank x8 organisation requires platforms that support registered ECC memory; it will not function in standard desktop or laptop systems that accept only unbuffered non-ECC modules.

Simple slot insertion

Align the notch with the motherboard key and press until the latches click. Common issues include mixing registered and unbuffered DIMMs, populating slots in the wrong channel order, or installing in consumer boards that lack ECC support.

Questions about this item

Does this 288-pin DDR4 ECC RDIMM require a server or workstation motherboard that supports registered memory?

Yes, this module is an ECC RDIMM designed for DDR4 servers and workstations only; it will not work in desktop or laptop systems that accept unbuffered memory.

If I add this 2Rx8 dual-rank module to a system that already has single-rank DDR4 2133 RDIMMs, will it run at the same speed?

The module runs at DDR4 2133 with CL15 latency at 1.20 V; the memory controller will typically clock all installed DIMMs to the lowest common speed and timing.

How can I confirm the module is operating as ECC registered memory after installation?

Check the system BIOS or a hardware utility such as dmidecode; it should report the DIMM as 16 GB DDR4 2133 registered ECC with a 2Rx8 organisation.
