SAMSUNG M321R4GA0EB2-CCP 32GB DDR5-6400 RDIMM 1RX4 1.1V server RAM

SKU CH-TN07-8XZBY MPN M321R4GA0EB2-CCP

32 GB DDR5-6400 RDIMM server memory module running at 1.1 V for high-density enterprise workloads

  • 32 GB capacity supports larger server workloads
  • DDR5 6400 MHz data rate accelerates memory throughput
  • RDIMM form factor adds register stability for servers
  • Single-rank 1Rx4 organisation balances density and speed
  • 1 V operating voltage reduces power draw

Server DDR5-6400 RDIMM

This 32 GB registered DDR5 module runs at 6400 MHz and operates at 1.1 V. It is built for multi-socket servers and workstations that require registered memory with single-rank x4 organisation.

Sustained throughput stability

Registered buffering and on-die ECC protect data integrity during continuous workloads. The low 1.1 V supply reduces thermal pressure when all channels are populated at rated speed.

DDR5 interface limits

The DDR5 standard tops out at the rated 6400 MHz transfer rate for this module. Higher frequencies would require platform support and memory controllers not guaranteed by the base specification.

  • DDR5 6400 MHz data rate accelerates memory throughput
  • RDIMM form factor adds register stability for servers
  • Single-rank 1Rx4 organisation balances density and speed

Questions about this item

How much power does the 1.1 V DDR5 RDIMM draw when the server runs continuously?

Operating at 1.1 V, this DDR5 RDIMM reduces voltage compared with earlier generations, so sustained all-day workloads draw less power and generate less heat inside the chassis.

What motherboard feature is required to install this 32 GB registered module?

The system must provide DDR5 RDIMM slots with registered-memory support; unbuffered consumer boards cannot accept this module.

Will this 6400 MHz DDR5 RDIMM downclock automatically in a platform that only supports lower DDR5 speeds?

Yes, the module follows JEDEC DDR5 standards and will negotiate the highest common speed with the memory controller, running reliably at the platform's maximum supported rate.
