16 GB DDR4-3200 ECC registered server memory

This 16 GB DDR4-3200 module provides ECC registered memory for servers and workstations. It runs at PC4-25600 speed with CL22 latency and a 1.2 V operating voltage. The dual-rank design helps increase density per channel. It is built for systems that require registered DIMMs.

Check 288-pin DDR4 registered DIMM support

Verify that your motherboard accepts 288-pin DDR4 registered DIMMs and supports ECC functionality. The platform must be able to run memory at 3200 MT/s with CL22 timing. Confirm the CPU and chipset allow registered modules and the required voltage. Systems limited to unbuffered memory cannot use this module.

Fits registered DDR4 server and workstation builds

This module plugs into standard 288-pin DDR4 slots that are wired for registered operation. It frees a slot by delivering 16 GB in a single dual-rank stick. The registered buffer reduces electrical load on the memory controller. ECC protects data integrity in multi-socket or high-uptime environments.

Questions about this item

Does the HMA82GR7CJR8N-XN arrive as a single 16 GB DIMM or as a kit, and are any extra parts required for installation?

The module is supplied as one 16 GB 288-pin DDR4 registered DIMM; no additional components are needed beyond a compatible server or workstation slot.

When should I choose this 16 GB dual-rank CL22 registered module instead of a single-rank or non-ECC alternative?

Choose this 16 GB dual-rank CL22 registered DIMM when your server requires ECC registered memory and can benefit from the density of a dual-rank 16 GB stick.

What does the 3200 MT/s rating mean for actual throughput once the DIMM is installed in a server?

At 3200 MT/s the module transfers data at its rated DDR4-3200 speed, providing the bandwidth expected from a PC4-25600 registered DIMM in a compatible system.
