32 GB DDR5 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR5 5200 registered DIMMs built for servers and workstations that require ECC registered memory. It is not compatible with standard desktop platforms or with unbuffered and load-reduced modules.

32 GB capacity at CL42 latency

The dual-rank 1Rx4 modules deliver 32 GB total capacity with a CAS latency of 42 at 5200 MT/s. Workloads that exceed this capacity will require additional DIMM slots or higher-density modules not included in this kit.

Registered ECC at 1.1 V operation

The defining specification is the registered ECC design operating at 1.1 V under the JEDEC DDR5 standard. Systems that do not support registered ECC DDR5 cannot use this memory.

Highlights

  • ECC registered design protects data integrity in servers
  • 5200 MT/s DDR5 speed enables high-throughput workloads
  • Dual-channel 2×16 GB kit delivers 32 GB total capacity
  • 1 V operation reduces power draw per module

Questions about this item

Can I mix the 2x16GB 1Rx4 DDR5 5200 CL42 ECC Registered RDIMMs with my existing DDR5 Load-Reduced DIMMs?

No. The module is Registered ECC and must not be mixed with Load-Reduced or Unbuffered ECC memory.

How can I verify the dual-channel kit is running at the rated 5200 MT/s and CL42 timings after installation?

Check the memory speed and CAS latency in the server BIOS or with a system-information tool such as CPU-Z; they should show 5200 MT/s and CL42.

Does the 32GB kit include only the two 288-pin RDIMMs, or are heat spreaders and cables also supplied?

The box contains the two 16GB DDR5 5200 ECC Registered RDIMMs only; no heat spreaders or extra cables are included.
