32GB RDIMM for Server Workloads

This 32GB DDR4 3200 RDIMM module provides registered memory with ECC parity for servers and workstations. The dual-rank 2Rx8 organisation and CL22 timing deliver 25600 MT/s bandwidth at 1.20V. A register chip controls data flow to support dense memory configurations in multi-socket systems.

Suited to Registered ECC Platforms Only

This module fits systems that require registered DDR4 DIMMs with parity ECC. It will not work in platforms that accept only unbuffered UDIMMs or that lack support for registered memory. Buyers needing non-ECC memory or consumer SO-DIMM form factors must choose a different product.

Registered RDIMM Architecture

The on-module register buffers address and command signals, reducing electrical load on the memory controller. This registered design is the single specification that determines compatibility with server chipsets that mandate registered DIMMs.

Questions about this item

What motherboard feature must my server have to use this 32GB RDIMM?

The motherboard must provide a DDR4 RDIMM slot that accepts registered modules with ECC parity support at 1.20V.

How will this CL22 3200 module behave if I keep slower DDR4 RDIMMs in other slots?

The memory controller will run all installed RDIMMs at the speed of the slowest module, so this stick will downclock to match the older ones.

How can I confirm the module is running as 2Rx8 registered ECC after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify 32GB capacity, 2Rx8 organization, registered type and ECC parity enabled.
