Compatible DDR5 ECC RDIMM kit

This 64 GB kit contains two 32 GB DDR5 4800 CL40 registered DIMMs built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. Each module runs at 1.1 V and uses 1Rx4 organisation with on-die ECC for data integrity. The 288-pin RDIMM form factor fits the server-grade memory slots on that platform.

Capacity and headroom

Two 32 GB modules give 64 GB total, enough for large dataset processing, virtualisation hosts and multi-threaded rendering workloads. The registered buffer reduces electrical load on the memory controller, allowing the platform to populate all slots without signal degradation. Workloads that exceed 64 GB will require additional kits or higher-density modules.

Registered ECC requirement

This kit is registered ECC DDR5 RDIMM; it will not function in consumer motherboards that accept only unbuffered non-ECC UDIMMs. Buyers whose systems require unbuffered memory must choose a different module type.

Questions about this item

Can I add these 4800 CL40 DDR5 ECC RDIMM modules to a system that already has DDR5 ECC RDIMM memory installed?

Yes, you can add them alongside existing DDR5 ECC RDIMM memory as long as your motherboard supports the same speed, voltage and registered configuration.

How can I verify the kit is running at 4800 MT/s with CL40 timings after installation?

Check the memory speed and latency in your BIOS/UEFI or use a system information tool such as CPU-Z to confirm DDR5-4800 and CL40 operation.

What comes in the box and do I need any extra brackets or cables?

The package contains the two 32 GB 288-pin DDR5 RDIMM modules only; no brackets, cables or additional hardware are included.
