SAMSUNG M321R4GA3EB2-CCP 32 GB DDR5-6400 ECC Registered 288-pin DIMM server RAM

SKU CH-B2QS-S98VT MPN M321R4GA3EB2-CCP

32 GB DDR5 ECC registered DIMM running at 6400 MHz with 1.10 V operation

  • 32 GB capacity supports dense server workloads
  • DDR5-6400 speed delivers 51200 MT/s data rates
  • ECC protection detects and corrects memory errors
  • Registered signal processing improves bus stability
  • 10 V operation reduces power draw per module

Server Memory Capacity

This Samsung DDR5 module delivers 32 GB of registered ECC memory for server workloads. The dual-rank design supports data integrity in multi-socket platforms. It targets administrators expanding memory in compatible enterprise systems.

DDR5-6400 Performance

Operating at 6400 MHz with a PC5-51200 rating, the module runs at 1.10 V. The registered buffer and ECC provide stability for sustained throughput. Headroom depends on the platform memory controller and populated slot count.

288-Pin DIMM Interface

The 288-pin DDR5 DIMM form factor fits standard server memory slots. Compatibility requires a platform qualified for DDR5-6400 registered ECC DIMMs. Systems limited to lower speeds or unbuffered memory cannot use this module.

Questions about this item

Can the 32 GB DDR5-6400 ECC registered DIMM be mixed with slower DDR5 modules in the same server?

The module runs at 6400 MHz and 1.10 V; the memory controller will down-clock all installed DIMMs to the speed of the slowest one, so mixing is possible but total bandwidth drops to the lowest common rate.

How can I verify the 32 GB DDR5-6400 module is operating at its rated 6400 MT/s after installation?

Check the BIOS memory information or a tool such as dmidecode; both should report the configured speed as 6400 MT/s and the voltage as 1.10 V for this DIMM.

Does the 288-pin DDR5-6400 ECC registered DIMM ship with a heatsink or any cables that must be purchased separately?

The unit is a bare 288-pin DIMM; no heatsink, cables or additional accessories are included in the box.
