  • 288-pin UDIMM fits standard server slots

16GB DDR4 ECC UDIMM for servers

This module delivers 16GB of DDR4 memory rated at 2666MHz with ECC error correction. It uses an unbuffered 288-pin UDIMM form factor running at 1.2V. The kit contains a single stick built with major OEM chips.

DDR4 2666 speed and CAS 19 latency

The PC4-21300 standard sets the practical bandwidth ceiling for this module. CAS latency of 19 defines the timing window for read operations at the rated frequency. Unbuffered ECC design means the memory controller handles all signalling directly without a register buffer.

16GB capacity with dual-rank 2Rx8 organisation

The 2Rx8 layout provides two ranks per module, allowing the controller to interleave accesses for better utilisation. Sixteen gigabytes suits typical entry-level server workloads such as virtualisation hosts or database nodes. Systems needing more than 16GB per slot or registered DIMM support cannot use this kit.
