DDR5 4800MHz ECC RDIMM for servers

This module is a 16GB DDR5 4800MHz registered DIMM with ECC and a 1Rx8 organisation. It operates at 1.1V and uses a 288-pin interface. The memory is built for server platforms that require registered, error-correcting DDR5 modules.

Suited for DDR5 registered server slots.

The kit fits servers that accept DDR5 4800MHz PC5-38400 registered ECC RDIMMs. It will not work in consumer desktop motherboards or laptops that use unbuffered memory. Builders needing non-ECC or unregistered modules should look elsewhere.

16GB capacity with single-rank headroom

The single 16GB rank leaves additional DIMM slots free for further expansion on compatible motherboards. At 4800MHz with CL40 latency it handles typical server workloads, though very large datasets or heavy virtualisation may exceed the single-module capacity.

Questions about this item

What type of motherboard slot is required for this 288-pin DDR5 RDIMM?

This module requires a 288-pin DDR5 DIMM socket that supports registered ECC memory; the board must list DDR5 RDIMM compatibility.

Will this single-rank 1Rx8 module run with dual-rank RDIMMs already installed?

Mixing ranks is often supported but depends on the server platform; consult the motherboard manual for approved population rules with 1Rx8 modules.

How can I verify the 4800MHz speed and CL40 latency are active after installation?

Enter the BIOS or use a tool like CPU-Z to confirm the memory reports DDR5-4800 with CAS latency 40 and ECC registered operation.
