NEMIX RAM RS700A-E12-RS12U 384GB (12x32GB) DDR5 4800 CL40 ECC RDIMM memory upgrade

SKU CH-12T1-SKHCC MPN RS700A-E12-RS12U

Adds 384 GB of DDR5 4800 ECC registered memory in a 12-module kit tuned for ASUS RS700A-E12-RS12U servers

  • Total capacity384 GB (12 × 32 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 384 GB total capacity from twelve 32 GB modules
  • DDR5 4800 speed with CL40 latency for server workloads
  • ECC registered RDIMM protects data integrity under load
  • 10 V operation reduces power draw in dense configurations
  • Validated for ASUS RS700A-E12-RS12U 1U dual-processor server

Compatibility and Use Cases

This 384GB kit is built for the ASUS RS700A-E12-RS12U 1U dual-processor server. It suits administrators upgrading memory capacity in that specific platform. Builders working with other server models, desktop motherboards, or workstations that require unbuffered memory should look elsewhere.

Deciding Specification

The registered ECC RDIMM design with 1Rx4 organisation and DDR5 4800 speed is the single specification that determines fit. Only systems that accept registered DDR5 ECC modules at this data rate and rank configuration will operate correctly with this kit.

Questions about this item

Does the 1Rx4 rank and CL40 latency limit throughput when all twelve slots are populated on the RS700A-E12-RS12U?

The kit runs at DDR5 4800 with CL40 timings across all twelve 32 GB modules; the 1Rx4 organisation is the native density for this platform and does not impose an extra bottleneck.

What is the power draw and thermal output of the 384 GB kit at 1.10 V during continuous operation?

Each module operates at 1.10 V with no heat spreader, so the kit relies on the server’s directed airflow; total power scales with the twelve registered DIMMs under sustained load.

Which motherboard and CPU combination must already be installed for this memory kit to function?

The memory is validated for the ASUS RS700A-E12-RS12U 1U dual-processor server; that exact system must be present for the registered ECC RDIMMs to initialise.
