Server Memory for Enterprise Workloads

This 32GB DDR5 RDIMM delivers ECC Registered operation at 6400 MT/s with CL52 latency. It targets servers and workstations that require error correction and registered signalling for multi-module stability. The module operates at 1.10V and includes on-die ECC plus side-band ECC for data integrity. A dedicated temperature sensor supports platform thermal management.

DDR5 RDIMM Platform Constraints

Multi-channel performance depends on the specific motherboard and CPU combination installed. The module follows the 288-pin DDR5 RDIMM standard and requires a platform that supports registered memory with ECC. Plug-and-Play support allows basic operation at rated speed without manual tuning. Systems without registered memory support cannot use this module.

32GB Capacity Determines Fit

The single-module 32GB capacity suits configurations needing high density per slot. Builders who need more storage per channel must populate additional slots with identical modules. Buyers who want non-ECC or unbuffered memory for consumer platforms cannot use this part. The lack of a heat spreader means airflow must be managed by the chassis design.

Questions about this item

Should I pick this 32GB DDR5 6400 CL52 module or a different capacity from the same series?

This is a single 32GB RDIMM; add multiple modules to reach the total capacity your motherboard and CPU support.

What does DDR5 6400 (PC5 51200) mean for actual throughput in a server build?

The module runs at 6400 MT/s with CL52 timing, delivering high bandwidth for multi-threaded workloads when paired with a compatible platform.

How does the 288-pin DDR5 RDIMM interface and ECC registration affect compatibility and error handling?

It uses the standard 288-pin DDR5 RDIMM form factor with on-die and side-band ECC plus a dedicated temperature sensor, requiring a motherboard that supports registered ECC memory.
