System-specific DDR5 kit

This 32 GB kit contains two 16 GB DDR5-4800 ECC registered DIMMs built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. It targets IT professionals and system integrators who need validated, error-correcting memory for mission-critical workloads.

Registered ECC with major OEM chips

The modules use Samsung, Micron or Hynix components in a 1Rx8 layout at 1.1 V with CL40 latency. Registration and on-die ECC improve signal integrity and data accuracy under sustained server loads, while the 288-pin RDIMM form factor matches the platform's memory slots exactly.

Straightforward DIMM installation

Populating the correct channels takes minutes when the motherboard manual is followed; the kit ships as a matched pair so no mixing occurs. Builders who need more than 32 GB or non-registered UDIMMs must select a different product, as this kit is fixed at two registered ECC modules.

Questions about this item

Will the 288-pin DDR5 RDIMM modules need replacement after a certain period?

These modules are built with major OEM chips and carry a lifetime replacement warranty, so no scheduled replacement is required.

What is the first limit reached during sustained workloads on this CL40 1Rx8 kit?

The CAS latency of CL40 at DDR5 4800 sets the timing boundary before bandwidth or capacity becomes the bottleneck.

How much heat and power will the 1.1 V registered DIMMs produce running all day?

Operating at 1.1 V without a heat spreader keeps power draw and thermals low for continuous server operation.
