32GB DDR5 ECC RDIMM for server upgrades

This module delivers 32GB of DDR5 6400 registered ECC memory in a single 288-pin DIMM. It targets administrators expanding capacity in compatible Micron-referenced platforms. The 2Rx8 organisation and 1.10V operation match the original specifications. Systems needing non-ECC or unbuffered DIMMs should look elsewhere.

Registered ECC with Micron chipset

The decisive attribute is the registered ECC design built on Micron DRAM ICs, which provides error correction and signal buffering required by qualified server boards. Standard desktop motherboards cannot use this module because they lack registered-memory support. Buyers must verify their platform accepts DDR5 RDIMM before purchasing.

Steady throughput at 1.10V

Under sustained workloads the module runs at the standard DDR5 voltage of 1.10V, maintaining the rated 6400 MT/s data rate without elevated power draw. The absence of a heat spreader means airflow across the PCB is necessary for thermal stability during prolonged operation. Environments with restricted cooling should plan accordingly.

Questions about this item

How does the 6400 MT/s speed translate once the module is installed in a server?

The module runs at DDR5 6400 (PC5-51200) with CAS latency 32, delivering that data rate when the platform memory controller is configured for 6400 MT/s operation.

What does the RDIMM registered interface mean for memory capacity limits?

As a registered DIMM it places a register on the command bus, letting the memory controller drive more ranks per channel than unbuffered modules allow.

Will the 288-pin DDR5 form factor fit my server's DIMM slots?

Yes, it uses the standard 288-pin DDR5 RDIMM layout; verify your system manual for supported DDR5 RDIMM population rules.
