16 GB DDR4 ECC UDIMM kit

This kit provides 16 GB of DDR4 ECC unbuffered memory in two 8 GB modules. It targets servers, workstations and NAS devices that require error-correcting code for data integrity. IT professionals and enthusiast builders use it to expand compatible platforms.

DDR4 2666 CL19 1.2 V specification

The modules run at DDR4 2666 (PC4 21300) with a CAS latency of CL19 and operate at 1.20 V. Each stick is a single-rank 1Rx8 design using major OEM chips from Samsung, Micron or Hynix. This exact speed, latency and voltage combination determines whether the kit matches the motherboard requirements.

Thermals and power in normal use

Without heat spreaders the modules rely on case airflow for cooling and run at the standard 1.20 V DDR4 voltage. Power draw stays within the normal range for unbuffered DDR4 ECC UDIMMs under typical workloads. Acoustic output is silent because no active cooling is present.

Questions about this item

What does CL19 mean when the kit runs at DDR4 2666 in a real system?

CL19 sets the delay between a read command and data availability at 19 clock cycles; at DDR4 2666 speed this determines the latency before each access begins

What does the PC4 21300 rating cap in practice?

PC4 21300 specifies a peak transfer rate of 21 300 MB/s per module; the motherboard memory controller and BIOS settings determine the actual throughput achieved

What physical slot and clearance does this 288-pin UDIMM kit need?

Each module uses a standard 288-pin DDR4 UDIMM slot and has no heat spreader, so it fits in low-profile server and workstation boards with tight DIMM spacing
