NEMIX RAM RS720-E11-RS12U 96GB (6x16GB) DDR5 4800 ECC RDIMM memory upgrade

SKU CH-SHKZ-FXEJS MPN RS720-E11-RS12U

A 96 GB registered DDR5 ECC kit of six 16 GB modules at 4800 MHz CL40 for the ASUS RS720-E11-RS12U server

  • Total capacity96 GB (6 × 16 GB)
  • Rated speedDDR5 4800 (PC5 38400)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL40
  • Buffer typeRegistered
  • Rated voltage1.1 V
  • 96 GB total capacity from six 16 GB modules
  • DDR5 4800 speed for high-throughput server workloads
  • ECC registered design protects data integrity under load
  • 10 V operation reduces power draw per module
  • Validated for ASUS RS720-E11-RS12U 2U dual-socket server

Target system and workload fit

This 96GB kit is built for the ASUS RS720-E11-RS12U 2U dual-socket server and suits administrators who need registered ECC memory for virtualisation, databases or high-throughput compute. The six 16GB modules fill the board in a balanced 1Rx8 layout at DDR5 4800. Buyers with single-socket platforms, consumer motherboards or workloads that demand higher frequencies should look elsewhere.

Deciding specification

Registered ECC RDIMM operation at DDR5 4800 with a CL40 latency and 1.10V voltage is the single spec that determines compatibility; the memory controller must support registered modules and the DDR5 4800 JEDEC profile for the kit to function.

Questions about this item

Does the CL40 latency become a bottleneck during sustained server workloads?

CL40 is the rated CAS latency for these DDR5 4800 modules; latency remains constant under load.

How much heat do the six 16 GB modules generate when running continuously at 1.10 V?

The kit operates at 1.10 V without heat spreaders; registered DDR5 RDIMMs typically run cooler than unbuffered equivalents.

Which ASUS 2U dual-socket server motherboard is required for this 288-pin RDIMM kit?

This memory kit is validated for the ASUS RS720-E11-RS12U server platform.
