  • Dual-rank x4 configuration maximises density per slot

Server-grade DDR4 module

This 32GB Crucial RDIMM operates at DDR4 2400 with CL17 latency and 1.20V. It uses Micron chips on a 288-pin dual-ranked registered design that includes ECC parity for error correction. The module delivers up to 25.6 GB/s bandwidth and is sold new for enterprise server installations.

Suited for registered ECC platforms

The module fits servers and workstations that require registered DDR4 memory with ECC support. It will not work in consumer desktop boards that accept only unbuffered non-ECC DIMMs, nor in systems limited to lower capacities per slot. Buyers needing unregistered memory or higher single-module densities should look elsewhere.

Capacity headroom at 32GB

A single DIMM provides 32GB, and the platform can scale up to 64GB where the memory controller and slot count allow. Dual-ranked organisation helps populate high-capacity configurations efficiently. Workloads exceeding the per-slot or per-channel limits of the host system will require additional modules or a different platform.

Points forts

  • Registered ECC design prevents data errors for reliability
  • DDR4 2400 speed delivers up to 25.6 GB/s bandwidth
  • 20V operation reduces power consumption per module

Questions sur cet article

What server motherboard slot and chipset are required for this 288-pin DDR4 2400 registered ECC module?

The module fits a 288-pin DDR4 DIMM slot on a server motherboard that supports registered ECC memory and a 1.20 V operating voltage.

Can this CL17 dual-ranked 32 GB stick run with older DDR4 2133 registered modules already in the system?

Yes, the memory controller will down-clock all modules to the lowest common speed, so the 2400 MT/s stick will operate at 2133 MT/s alongside existing registered ECC DIMMs.

How do I confirm the module is running at 2400 MT/s with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode; it should report 2400 MT/s, CL17 timings, 1.20 V, registered type and ECC enabled.
