16GB DDR5-4800 ECC module for workstations

This 16GB DDR5-4800 CL40 DIMM is built for workstations that require error-correcting code memory without registered buffering. It operates at 1.10V and uses a 288-pin form factor. The single-rank 1Rx8 organisation suits systems that populate each channel with one module per slot.

Simple DIMM installation with ECC verification

The unbuffered 288-pin design fits standard DDR5 slots directly, so no extra cables or brackets are needed. After seating the module, enable ECC in the system firmware; some platforms disable it by default. If the BIOS does not recognise the CL40 timing, a manual timing entry may be required for stable operation.

DDR5-4800 bandwidth ceiling and voltage constraint

At 4800 MT/s the module delivers PC5-38400 throughput, which caps memory bandwidth for workloads that scale beyond this data rate. The fixed 1.10V operating voltage prevents overclocking headroom, so the rated speed is the practical maximum. Systems needing higher frequencies or lower latencies must use modules specified for those parameters.

Questions about this item

How can I verify the module is running at the rated DDR5-4800 speed and CL40 timings after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 4800 MT/s with CAS latency 40; CPU-Z or similar tools will also report the 1.10 V operating voltage and single-rank 1Rx8 organisation.

What comes in the box and are any extra components required for installation?

The package contains one 16 GB DDR5 288-pin DIMM; no additional cables, brackets or cooling parts are needed — just an available DDR5 slot on a compatible workstation motherboard.

When should I choose this 16 GB DDR5-4800 CL40 ECC unbuffered module over other capacities or speeds?

Select this 16 GB stick when your workload needs ECC data integrity and the platform supports DDR5-4800 unbuffered memory; add multiple modules to reach the total capacity your workstation requires.
