Sixteen green DDR5 RDIMM modules in a row

NEMIX RAM

NEMIX RAM RS520A-E12-RS12U 512GB (16x32GB) DDR5 4800 ECC RDIMM memory upgrade

SKU CH-0PQ1-Q5FM0 MPN RS520A-E12-RS12U

512 GB DDR5 server kit with 16 registered ECC modules at 4800 MHz CL40 1.1 V for the ASUS RS520A-E12-RS12U

  • Capacity512GB (16 x 32GB)
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 512 GB total capacity from 16 modules of 32 GB each
  • DDR5 4800 speed rated at PC5-38400 for server workloads
  • ECC registered RDIMM design protects data integrity in critical systems
  • 10 V operating voltage with CL40 latency for efficient performance
  • 288-pin 1Rx4 configuration validated for ASUS RS520A-E12-RS12U server

Suited workloads

This kit targets the ASUS RS520A-E12-RS12U single-socket 2U server with sixteen DDR5 slots. IT teams running virtualisation, database or high-throughput compute workloads that require registered ECC memory at 4800 MT/s will find the 512GB capacity a direct fit. Builders using consumer motherboards, workstations without registered DIMM support, or any platform that accepts only unbuffered modules should look elsewhere. Systems limited to lower maximum capacities or different pin layouts cannot use this kit.

Deciding specification

The module is a 288-pin DDR5 RDIMM with ECC and registered signalling at 1.10V. Only motherboards designed for registered DDR5 DIMMs and wired for the 288-pin DDR5 interface will POST with these modules; any board expecting unbuffered, SODIMM or earlier DDR generations will be physically and electrically incompatible.

Perguntas sobre este artigo

Does the 512 GB kit need any periodic maintenance or component replacement?

The DDR5 ECC RDIMM modules are solid-state with no moving parts and no heat spreaders, so no routine maintenance or replacement is required under normal server operation.

What limit appears first when the 16 modules run at DDR5 4800 continuously?

The registered 1Rx4 organisation and CL40 latency define the throughput ceiling; sustained load will hit the memory controller's bandwidth limit before any thermal throttle on the bare modules.

How much noise and heat do the bare 288-pin RDIMMs generate in a 2U chassis all day?

Without heat spreaders the modules rely on chassis airflow; they add no fan noise and their 1.10 V operating voltage keeps incremental heat low in a properly cooled ASUS RS520A-E12-RS12U.
