  • ECC registered design corrects errors for mission-critical reliability
  • Dual-rank 2Rx8 organisation maximises bandwidth per channel
  • 10 V standard voltage reduces power draw per module

Server DDR5 capacity

This 64GB kit delivers two 32GB registered ECC modules built for DDR5 servers and workstations. Each module runs at 5600 MT/s with CL46 latency at the standard 1.10V. The dual-rank x8 organisation and 288-pin RDIMM form factor suit multi-channel platforms that require error correction.

Sustained throughput

Registered buffering and on-die ECC keep data integrity intact during continuous workloads such as virtualization, database transactions or compile farms. Dual-rank density lets the memory controller interleave accesses across both modules, maintaining bandwidth when all channels are populated. The 1.10V operating point remains stable without voltage scaling.

Thermals and power

Bare modules without heat spreaders rely on chassis airflow, so fan speed and inlet temperature determine module temperature. At 1.10V the kit draws minimal power per DIMM, reducing the thermal load on dense server configurations. Acoustic output is governed entirely by the system fans, not the memory itself.

Questions about this item

Will the 1.10 V DDR5 5600 RDIMMs run cool and quiet under continuous server loads?

The modules operate at the standard 1.10 V DDR5 voltage with no heat spreader, so they rely on the server's chassis airflow; power draw is typical for 2Rx8 registered DIMMs at this speed.

Does my system need a DDR5 RDIMM-capable motherboard and CPU to use this 64 GB kit?

Yes — the kit requires a server or workstation platform that supports 288-pin DDR5 ECC registered memory; desktop and laptop systems cannot accept these modules.

Can I add this 2Rx8 EC8 RDIMM kit alongside existing DDR5 RDIMMs of different capacities?

The 2Rx8 dual-rank organisation follows the DDR5 RDIMM standard, but population rules depend on your platform's memory controller; consult the system manual for supported rank mixes and channel placement.
