SAMSUNG

SAMSUNG 64GB DDR5 4800MHz PC5-38400 ECC RDIMM 2Rx4 EC8 10x4 1.1V 288-Pin Server RAM M321R8GA0BB0-CQK

SKU CH-4E6C-XVEWH

Adds 64 GB of DDR5 ECC registered memory at 4800 MHz for compatible servers and workstations

  • 64 GB capacity expands server memory headroom for larger workloads
  • DDR5 4800 MHz speed delivers high bandwidth for data-intensive tasks
  • ECC registered RDIMM protects data integrity in mission-critical environments
  • 2Rx4 dual-rank organisation increases memory density per channel
  • 1 V JEDEC standard voltage reduces power draw per module

Server memory for DDR5 platforms

This Samsung module delivers 64 GB of DDR5 ECC registered memory for compatible servers and workstations. The dual-rank 2Rx4 organisation with EC8 10x4 configuration supports data integrity in mission-critical environments. It operates at the JEDEC-standard 1.1 V and fits 288-pin DDR5 DIMM slots.

DDR5-4800 speed ceiling and mixing limits

The module runs at up to 4800 MHz, PC5-38400, which is the baseline DDR5 data rate. Registered DIMMs with EC8 10x4 layout cannot be mixed with EC4 9x4 registered modules or with unbuffered, load-reduced or non-ECC memory types. System manuals dictate the required slot population and channel rules.

Registered DIMM build and 288-pin fit

The registered design places a buffer on the command bus to reduce electrical load on the memory controller. Gold-edge contacts on the 288-pin connector ensure reliable seating in server boards that support DDR5 RDIMMs. This module is not compatible with desktop or laptop computers that use unbuffered memory.

Questions about this item

Should I pick the single 64 GB module or combine it with other capacities?

This listing is for one 64 GB DDR5 module. Add matching modules to reach your server's required total capacity.

What does the 4800 MHz rating deliver in a live server?

The module runs at up to 4800 MHz, giving PC5-38400 bandwidth for high-throughput workloads.

Will the 288-pin DDR5 RDIMM fit my system's memory slots?

It uses the standard 288-pin DDR5 RDIMM form factor with ECC and registered signalling for compatible server platforms.
