32GB DDR4 ECC Registered Module

This 32GB DDR4 SDRAM module delivers 2133MHz speed with CL15 latency and ECC error correction. The registered quad-rank design targets servers and workstations that require maximum capacity per slot and data integrity for continuous operation.

288-pin DDR4 registered DIMM

The module plugs into a standard DDR4 288-pin slot and operates at 1.2V. Registered signalling reduces electrical load on the memory controller, allowing higher-density configurations. Quad-rank organisation means each DIMM presents four logical ranks, so the platform must support that rank count per channel.

Upgrade from lower-capacity or non-ECC DDR4

Replacing smaller unbuffered modules with this 32GB registered part increases total memory without adding slots, but only where the motherboard and CPU support registered quad-rank DIMMs. Systems limited to unbuffered or dual-rank memory cannot use this module.

Soalan tentang produk ini

How does the quad-rank layout limit the number of DIMMs a single memory channel can accept?

Each module presents four ranks, so most server chipsets allow only one quad-rank DIMM per channel before hitting the rank-per-channel ceiling.

What is the power draw per module when the kit runs continuously at its rated 2133 MT/s speed?

The module operates at 1.2 V, matching the standard DDR4 voltage for registered ECC DIMMs at this frequency.

Which motherboard feature must already be present for the ECC and registered functions to operate?

The platform must provide a DDR4 RDIMM slot with ECC support in the chipset and BIOS.
