Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM RS720Q-E11-RS8U 256GB (16x16GB) DDR5 4800 CL40 ECC RDIMM memory upgrade

SKU CH-MXV9-V7AAM MPN RS720Q-E11-RS8U

Adds 256GB of DDR5 4800 CL40 ECC registered memory in sixteen 16GB modules for ASUS RS720Q-E11-RS8U servers

  • Total capacity256 GB (16 × 16 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 256GB total capacity across 16 modules for high-density server workloads
  • DDR5 4800 speed with PC5-38400 bandwidth for data-intensive applications
  • ECC registered RDIMM design ensures data integrity and signal stability
  • 1V operating voltage reduces power draw in 2U4N configurations
  • CL40 latency with 1Rx8 rank optimises throughput for ASUS RS720Q-E11-RS8U

System-Specific DDR5 Server Memory

This 256GB kit contains sixteen 16GB DDR5 4800 registered ECC RDIMMs built for the ASUS RS720Q-E11-RS8U high-density server. IT teams choose it when capacity and error correction matter more than low latency.

Upgrading from Lower-Capacity DDR5 RDIMMs

The jump is worth it when workloads exceed the headroom of smaller kits and the platform supports 16 populated slots at 4800 MT/s with CL40 timing. It does not suit systems limited to fewer channels or slower memory controllers.

Build Integration for 2U4N Density

Each 1Rx8 module runs at 1.1V without a heat spreader, fitting tightly spaced DIMM slots in the target chassis. The registered buffer eases electrical load on the memory controller, freeing signal margin for full population across all nodes.

Questions about this item

Will the 288-pin DDR5 RDIMM modules fit the memory slots on the ASUS RS720Q-E11-RS8U server?

Yes, the 288-pin DDR5 RDIMM form factor matches the registered DIMM slots on the ASUS RS720Q-E11-RS8U, and the kit is built for that platform.

What is the correct order for populating the 16 modules across the server's memory channels?

Follow the ASUS RS720Q-E11-RS8U manual for the exact channel population sequence; install the 1Rx8 registered modules in the prescribed slot order to enable all 16 modules.

When should the 16 registered DDR5 modules be reseated or replaced in the ASUS RS720Q-E11-RS8U?

Reseat modules if the server reports correctable ECC errors or fails to recognise the full 256 GB; replace any module that shows persistent uncorrectable errors after testing.
