Capacity 64GB (2 x 32GB)

  • 64 GB dual-channel kit expands server capacity
  • DDR5 4800 MT/s with CL40 latency accelerates data throughput
  • ECC registered RDIMM corrects errors for data integrity
  • Dual-rank 2Rx8 organisation increases memory density per channel
  • 10 V standard voltage maintains DDR5 efficiency

Server ECC Registered Memory Kit

This 64GB kit contains two 32GB DDR5 RDIMM modules built for servers and workstations that require ECC registered memory. The dual-rank x8 organisation and 1.10V operation match DDR5 server platform specifications. It is not compatible with desktop or laptop computers that use unbuffered memory.

Straightforward DIMM Installation

The 288-pin modules seat in standard DDR5 RDIMM slots following the motherboard channel guide. A common mistake is mixing registered DIMMs with unbuffered memory or populating slots in the wrong order, which prevents the system from posting. Verify the platform supports DDR5 ECC registered memory before fitting.

Steady Throughput Under Load

Rated at 4800 MHz with CL40 latency, the kit delivers consistent bandwidth during sustained workloads such as virtualisation, database caching or large-scale compute. ECC error correction and registered buffering maintain data integrity across long runs without the throttling sometimes seen in consumer modules.

Questions about this item

How can I verify the 4800 MHz speed and CL40 latency are active after installing these modules?

Enter the system BIOS or use a tool such as CPU-Z to confirm the memory reports DDR5 4800 and CAS latency 40; the registered ECC design will also appear in the hardware inventory.

What is included in the box and what must be sourced separately?

The package contains two 32 GB DDR5 RDIMM modules (288-pin, 1.10 V, 2Rx8); no cables, brackets or additional hardware are supplied.

Which version should I choose for a dual-channel server board?

This 64 GB kit (2 x 32 GB) is built as a matched dual-channel set for DDR5 ECC registered platforms; select it when your board requires 2Rx8 EC8 RDIMMs at 4800 MHz.
