DDR5 4800 ECC RDIMM for servers

This 16GB registered DIMM uses DDR5 technology at 4800 MT/s with a CAS latency of 40 and operates at the standard 1.10V. It is built with Samsung chipset components in a 1Rx8 configuration and fits 288-pin DDR5 slots.

Suited for registered-ECC platforms

The module targets servers and workstations that require registered ECC memory and will not function in systems that only accept unbuffered non-ECC DIMMs. Buyers needing higher-density modules or different rank configurations should verify their platform's qualified-vendor list before ordering.

1Rx8 registered ECC decides fit

The single-rank 1Rx8 registered ECC organisation is the specification that determines whether this DIMM matches the memory controller and channel population rules of the target server or workstation.

Questions about this item

How do I install this 288-pin DDR5 RDIMM and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify the server BIOS recognises the full 16GB at 4800MHz.

What maintenance or replacement will this ECC RDIMM need over time?

No routine maintenance is required; the module either passes POST or it fails, so replacement only happens if errors appear or capacity must grow.

What limit appears first when this 1Rx8 module runs sustained workloads?

The single-rank layout caps maximum bandwidth per channel, so throughput plateaus before thermal or voltage limits are reached.
