Sixteen green DDR5 RDIMM modules in a tray

NEMIX RAM

NEMIX RAM RS520A-E12-RS24U 512GB (16x32GB) DDR5 4800 ECC RDIMM memory upgrade

SKU CH-DF78-7DD2T MPN RS520A-E12-RS24U

512GB kit of 16 registered DDR5 ECC RDIMMs running at 4800MHz with CL40 latency for ASUS RS520A-E12-RS24U servers

  • Capacity512GB (16 x 32GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 512 GB total capacity for demanding server workloads
  • 16 modules of 32 GB each enable full population
  • DDR5 4800 speed with CL40 latency for high throughput
  • ECC registered design protects data integrity
  • 10 V operation reduces power draw per module

Compatibility & Use

This 512GB DDR5 ECC RDIMM kit is built for the ASUS RS520A-E12-RS24U single-socket 2U server. Sixteen 32GB modules run at 4800MHz with CL40 latency and 1.1V operation. Registered buffering and on-die ECC protect data integrity in virtualised and database workloads.

Who Should Look Elsewhere

Systems that accept only unbuffered UDIMM memory cannot use these registered modules. Builds limited to lower capacities or fewer than sixteen slots will not accommodate the full kit. Workstations requiring consumer DDR5 without ECC should choose a different product.

Deciding Specification

Registered ECC DDR5 at 4800MHz with 1Rx4 organisation is the single spec that determines fit. The motherboard must support 288-pin RDIMM slots, 1.1V voltage and the 512GB total capacity across sixteen sockets.

Perguntas sobre este artigo

Does the ASUS RS520A-E12-RS24U server require all 16 DDR5 RDIMM slots to be populated for this 512GB kit to operate correctly?

The kit provides 16 modules of 32GB each, matching the 16 DIMM slots in the compatible ASUS RS520A-E12-RS24U server for full population.

Can these registered ECC DDR5 modules be mixed with unbuffered non-ECC DDR5 DIMMs already present in the system?

No, registered ECC RDIMMs and unbuffered non-ECC UDIMMs use different signalling and cannot be installed together in the same server.

After installation, how can I confirm the modules are running at the rated DDR5 4800 speed with CL40 latency?

Check the BIOS memory information or use a system utility such as dmidecode to verify the reported speed shows 4800 MT/s and CAS latency reads CL40.
