32GB DDR4 2666 ECC RDIMM for Servers

This module delivers 32GB of DDR4 2666 registered ECC memory in a single 288-pin DIMM. It is built for server and workstation platforms that require error correction and registered signalling. The CL19 timing and 1.20V operation match standard DDR4 specifications for this speed grade.

Registered ECC limits for DDR4 2666

Registered DIMMs add a clock cycle of buffering that stabilises heavy memory loads but prevents use in consumer desktop boards that expect unbuffered modules. ECC functionality only activates on platforms with a compatible memory controller; otherwise the module operates as non-ECC registered memory. Mixing registered and unbuffered DIMMs is not supported.

32GB single-module capacity and headroom

A single 32GB stick fills one slot and leaves remaining DIMM sockets open for further expansion up to the platform maximum. The 2Rx4 organisation suits high-density server configurations. Systems limited to 16GB per slot or to unbuffered memory cannot use this module.

Questions sur cet article

Should I choose the 32GB module or add multiple sticks for my server?

This listing is a single 32GB DDR4 2666 ECC RDIMM; add more identical modules to reach your platform’s maximum capacity and enable multi-channel bandwidth.

What does the 2666MHz speed deliver in a live server workload?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, providing the rated throughput and error-corrected stability your platform negotiates at boot.

How does the 288-pin RDIMM interface limit real-world performance?

The registered 288-pin DDR4 interface caps transfer rate at 2666 MT/s and requires a compatible server chipset; bandwidth scales with populated channels, not the connector itself.
