Eight green DDR5 RDIMM modules in anti-static tray

NEMIX RAM

NEMIX RAM RS700-E11-RS4U 256GB (8x32GB) DDR5 4800 ECC RDIMM memory upgrade

SKU CH-AMZR-C5ZJJ MPN RS700-E11-RS4U

Adds 256GB of DDR5 4800 ECC registered memory in eight 32GB modules for the ASUS RS700-E11-RS4U server

  • Total capacity256 GB (8 × 32 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 256 GB total capacity across eight 32 GB modules
  • DDR5 4800 speed for high-throughput server workloads
  • ECC registered design protects data integrity under load
  • 1 V operation reduces power draw per module
  • Validated for ASUS RS700-E11-RS4U 1U dual-socket servers

Compatibility and intended use

This 256GB DDR5 kit is built for the ASUS RS700-E11-RS4U 1U dual-socket server. Registered ECC modules and 1Rx4 organisation match the platform’s memory controller requirements. IT teams upgrading that specific chassis can install the eight 32GB sticks without configuration changes. Builders targeting any other server, workstation or desktop platform should look elsewhere because the pin-out, registration and timing are tuned for this single model.

Deciding specification

Registered ECC DDR5 at 4800 MT/s with CL40 latency and 1.10 V operation is the defining attribute. The 288-pin RDIMM form factor, 1Rx4 rank structure and Samsung, Micron or Hynix DRAM ensure the electrical and timing profile the ASUS RS700-E11-RS4U expects. If your system demands a different speed, voltage, rank layout or unbuffered modules, this kit will not function correctly.

Questions about this item

Will the 288-pin DDR5 RDIMM modules require any periodic cleaning or component replacement after installation?

The modules have no moving parts or heat spreaders, so no scheduled cleaning or component replacement is needed once they are seated in the server.

What electrical or thermal limit is reached first when the 8x32GB kit runs continuously at 4800 MT/s in the ASUS RS700-E11-RS4U?

The registered ECC design and 1.10 V operating voltage keep power draw within the DDR5 RDIMM specification, so the platform memory-controller thermal envelope is typically the first limit encountered.

How much heat and fan noise does the 256 GB kit add when the server runs all day at full load?

Each 32 GB 1Rx4 module operates at 1.1 V without a heat spreader, adding minimal thermal load; the server's existing airflow and fan curves handle the extra heat without audible change.
