64GB DDR5 ECC RDIMM kit

This 64GB kit contains two 32GB DDR5 5600 CL46 registered DIMMs built for workstations and servers. Each module runs at 1.1V with a 2Rx4 layout and 288-pin form factor. ECC registered operation detects and corrects data errors in mission-critical workloads.

For ECC registered platforms only

These modules suit administrators upgrading compatible workstations, NAS units, servers or network switches that require registered ECC memory. They will not work in standard desktop computers or consumer motherboards that accept only unbuffered non-ECC RAM. Builders needing load-reduced or unbuffered DIMMs must choose a different product.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC circuitry combine with a dual-rank 2Rx4 architecture to deliver data-integrity protection for multi-socket server boards. This specification decides whether the kit matches your platform's qualified memory list. Verify that your system documentation calls for DDR5 5600 registered ECC RDIMMs before purchasing.

Questions about this item

How do I confirm the kit runs at 5600 MT/s with CL46 after installation?

Check the BIOS or UEFI memory information screen — it should report DDR5 5600 and CAS latency 46 for each 32 GB module.

What comes in the box and what must be purchased separately?

The box contains two 32 GB DDR5 5600 CL46 2Rx4 288-pin 1.1 V ECC Registered RDIMMs; no extra cables, brackets or software are included.

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

This 64 GB kit (2 × 32 GB) is built as a matched dual-channel pair for servers and workstations that require registered ECC memory.
