128GB DDR5 ECC RDIMM kit for ASUS WRX90E SAGE SE

This 128GB kit contains four 32GB DDR5 4800 registered ECC modules built for the ASUS Pro WS WRX90E SAGE SE workstation motherboard. It targets IT professionals and system integrators who need validated, high-capacity memory for mission-critical server and workstation workloads.

Registered ECC modules with 1.1V operation

The kit delivers registered DDR5 ECC RDIMMs rated at CL40 latency and 1.10V, using major OEM Samsung, Micron or Hynix components. Each 1Rx4 module installs directly into the 288-pin slots without additional configuration, providing error correction and signal integrity required for sustained heavy compute tasks.

128GB capacity across four 32GB modules

The total 128GB capacity is achieved with four 32GB RDIMMs, matching the motherboard's supported population rules. Buyers who need a different total capacity or a non-ECC unbuffered layout should select another kit, as this package is specific to registered ECC DDR5 requirements.

Questions about this item

Will the 1Rx4 registered DIMMs need any firmware or chip-level maintenance over their service life?

No firmware or chip-level maintenance is required; the registered DDR5 modules run at 1.10 V and are validated for continuous operation in the ASUS Pro WS WRX90E SAGE SE platform.

What limit appears first when the 128 GB kit runs at DDR5 4800 CL40 under sustained load?

The CL40 latency at 4800 MT/s sets the throughput ceiling; bandwidth and latency remain fixed at the rated PC5-38400 specification during extended workloads.

How much heat and power do the four 32 GB modules produce when the workstation runs all day?

Each module operates at 1.10 V without a heat spreader; total power draw stays within the standard DDR5 4800 registered DIMM envelope for 128 GB configurations.
