  • Capacity16GB
  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 16 GB capacity expands server memory headroom
  • DDR5 4800 speed delivers high data throughput
  • ECC registered design protects data integrity
  • 1 V operation reduces power draw
  • Validated for ASUS RS520A-E12-RS24U 2U server

Compatibility & use case

This module is built for the ASUS RS520A-E12-RS24U 2U server and similar single-socket platforms that require DDR5 4800 ECC registered memory. It suits administrators expanding capacity in validated server configurations. Builders assembling custom workstations, desktop PCs or non-registered systems should look elsewhere.

Deciding specification

The registered ECC RDIMM design with 1Rx8 organisation is the single factor that determines fit. Only motherboards that explicitly support registered DDR5 ECC modules at 4800 MT/s can use this part.

Questions about this item

Does this DDR5 RDIMM require an ASUS RS520A-E12-RS24U server motherboard with registered-memory support to operate?

Yes, the module is a 288-pin DDR5 4800 ECC registered DIMM built for the ASUS RS520A-E12-RS24U single-socket 2U server platform.

Can I mix this 1Rx8 CL40 1.10 V module with existing DDR5 RDIMMs of different rank or latency in the same server?

Mixing ranks or CAS latencies is not recommended; the server memory controller will run all channels at the slowest common timing and may disable ECC features.

After installation, how can I verify the module is running at 4800 MT/s with ECC active?

Check the BIOS memory information screen or the OS hardware report — both should show 4800 MT/s, CL40, 1.10 V and ECC enabled for the 16 GB DIMM.
