16GB DDR5 4800 ECC RDIMM

This 16GB registered DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It targets server and workstation administrators who need error-correcting memory for data-integrity workloads. The single-rank 1Rx8 organisation keeps electrical loading low on populated channels. Buyers who need non-ECC or unbuffered DIMMs for consumer platforms should look elsewhere.

Sustained-load behaviour

Registered buffering and on-die ECC maintain signal integrity during continuous read-write cycles typical of database or virtualisation tasks. The 4800MHz data rate delivers consistent throughput without the voltage headroom required for overclocked operation. Systems that demand higher frequencies or lower latencies than CL40 will not be satisfied by this specification.

Build and connectors

The 288-pin DIMM fits standard DDR5 server slots and uses a major-brand chipset for reliable yields. Registered signalling reduces the electrical load on the memory controller, allowing larger populations per channel. Installers must confirm the platform supports DDR5 RDIMM topology; the module will not function in systems limited to UDIMM or earlier DDR generations.

Questions sur cet article

How much heat does the 1.10 V DDR5 4800 RDIMM produce when the server runs continuously?

Operating at the standard DDR5 voltage of 1.10 V, the module draws less power than earlier generations, so sustained loads generate modest heat that typical server airflow handles without extra cooling.

What motherboard slot and CPU memory controller are required for this 288-pin RDIMM to function?

You need a DDR5-capable server or workstation board with a 288-pin RDIMM slot and a processor that supports registered ECC memory at 4800 MT/s; consumer desktop platforms will not accept this module.

Can this CL40 1Rx8 registered ECC module share a channel with other registered ECC DIMMs of different capacity or rank?

Yes, registered ECC DIMMs can be mixed on the same channel if the platform supports mixed-capacity populations, though the memory controller will run all modules at the lowest common speed and timing.
