16 GB DDR5 ECC unbuffered DIMM running at 4800 MHz with CL40 latency for workstation stability
This 16 GB DDR5-4800 module targets workstations and entry-level servers that require error-correcting code memory without registered buffering. It suits administrators who need single-rank density for straightforward population rules and 1.10 V operation for standard platform compatibility.
The CL40 latency and 4800 MT/s data rate deliver predictable bandwidth for long-running workloads such as rendering, compilation or virtualisation hosting. Single-rank organisation avoids the command-scheduling overhead of dual-rank modules, so throughput remains steady during extended memory-bound tasks.
The 288-pin DIMM fits any DDR5 UDIMM slot keyed for unbuffered ECC; no heat spreader means clearance is minimal but verify motherboard support for unbuffered ECC before purchase. Builders who need registered RDIMM or higher capacities per slot should look elsewhere.

The module operates at the standard DDR5 voltage of 1.10 V. Actual power draw depends on workload and the platform's memory controller; the kit itself has no separate power rating.
You need a workstation or server board with a 288-pin DDR5 DIMM slot and a CPU memory controller that supports DDR5-4800 unbuffered ECC memory.
Yes, provided the platform supports mixed-capacity DDR5 populations and all modules run at a common speed and voltage; the memory controller will negotiate the lowest common timing.
