Capacity 16GB (2 x 8GB)

  • ECC protects data integrity in server workloads
  • Unbuffered design lowers latency for responsive performance
  • 16 GB kit (2 × 8 GB) expands capacity efficiently
  • DDR4 2133 speed delivers reliable throughput
  • 288-pin DDR4 form factor fits standard server slots

Server DDR4 2133 ECC kit

This 16GB kit contains two 8GB DDR4 2133 modules built for servers and workstations that require error-correcting memory. The unbuffered design fits platforms that accept UDIMMs rather than registered DIMMs. Each stick uses a 2Rx8 organisation and standard 288-pin layout.

ECC unbuffered specification

The defining specification is ECC unbuffered DDR4 2133, which delivers single-bit error correction without the latency penalty of registered modules. Systems that require registered or load-reduced DIMMs cannot use this kit, and platforms limited to non-ECC memory will not activate the correction feature.

16GB dual-channel capacity

The 16GB total capacity split across two modules enables dual-channel operation on compatible server boards. It comfortably handles typical virtualisation hosts, database buffers and file-serving workloads. Memory-intensive applications such as large in-memory analytics or high-density container clusters will exhaust this capacity quickly.

Questions about this item

What real-world bandwidth does the PC4 17000 rating deliver in a dual-channel server?

Each module is rated for 17 GB/s peak transfer; a dual-channel system can utilise both modules simultaneously to double that throughput.

Does the 288-pin DDR4 interface impose any speed ceiling beyond the 2133 MT/s rating?

The 288-pin DDR4 slot accepts this module at its native 2133 MT/s; the platform's memory controller determines whether higher speeds are possible.

What physical space and slot type are required to install the 2Rx8 modules?

Two adjacent 288-pin DDR4 DIMM slots are needed; each stick is a standard-height unbuffered module with a 2Rx8 organisation.
