128 GB DDR4 ECC UDIMM kit for servers

This eight-module kit delivers 128 GB of DDR4 2133 memory in a 288-pin unbuffered DIMM form factor. Each 16 GB module operates at 1.2 V with CL15 latency and dual-rank x8 organisation. Error-correcting code protects data integrity in server and workstation workloads.

Unbuffered dual-rank design for compatible platforms

The UDIMM layout plugs directly into standard DDR4 server slots without registered buffering. Dual-rank x8 chips populate each module, so the memory controller sees two ranks per DIMM for improved interleaving. No heat spreader is fitted, keeping the modules low-profile for dense chassis.

Replaces non-ECC or lower-capacity DDR4 UDIMMs

Upgrading from non-ECC memory adds single-bit error correction and multi-bit detection for critical workloads. Moving from smaller 8 GB or 16 GB kits to this 128 GB set expands the addressable workspace for virtualisation and database tasks. The jump is worthwhile when the platform supports 2133 MHz unbuffered ECC and requires maximum DIMM population.

Perguntas sobre este artigo

What DDR4 speed and PC4 rating does this 128 GB kit run at?

The modules operate at DDR4 2133 MHz with a PC4-17000 transfer rate and CL15 latency.

What motherboard slot and pin count do these 16 GB modules need?

Each module is a 288-pin DDR4 UDIMM designed for unbuffered ECC DIMM slots on compatible servers or workstations.

How should the eight dual-rank sticks be seated for correct channel population?

Follow the system manual’s channel guidelines; populate matching slots per channel and press each 2Rx8 module until the retention clips lock.
