Certified 32GB DDR4 Server Memory

This 32GB DDR4 2666MHz ECC RDIMM is built for servers and workstations that require registered, error-correcting memory. It carries Supermicro certification and uses Micron chipset components. The module suits administrators who need validated compatibility for 288-pin DDR4 platforms.

Sustained Load Behaviour

Registered buffering and ECC protect data integrity during continuous, multi-threaded workloads. The 1.20V standard voltage and CL19 timing maintain stable operation without exceeding DDR4 baseline power. Dual-rank 2Rx4 organisation allows the memory controller to interleave accesses across ranks for consistent throughput.

Deciding Specification

The 2Rx4 dual-rank registered ECC configuration determines whether this module matches your system's qualified vendor list. Single-rank or unbuffered DIMMs will not substitute for this layout. Verify that your platform explicitly supports 32GB 2Rx4 RDIMMs before purchasing.

Questions about this item

How much power does the 1.20 V DDR4 2666 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20 V. Actual power draw depends on the server workload and the platform's memory controller; the module itself has no separate power rating.

What motherboard slot and memory controller features are required for this 288-pin RDIMM to function?

You need a DDR4 RDIMM slot that supports 288-pin registered ECC modules at 2666 MHz with 2Rx4 organisation and CL19 timing.

Will this 32 GB 2Rx4 registered stick work in a system that currently uses 1Rx4 or 1Rx8 DDR4 ECC modules?

Mixing ranks is platform-dependent; the server's memory controller and BIOS must support mixed-rank populations. Verify the system's qualified vendor list before combining different rank configurations.
