16 GB DDR4 ECC kit for workstations and servers

This kit provides 16 GB of DDR4 memory in a matched pair of 8 GB unbuffered UDIMMs rated at 2666 MHz with CL19 latency. ECC support helps maintain data integrity in workstations, servers and NAS systems that require error correction.

Verify motherboard ECC support

Ensure the board accepts unbuffered ECC UDIMMs and has two free 288-pin DDR4 slots for dual-channel operation. The modules run at 1.2 V and are backward compatible with 2133 MHz and 2400 MHz speeds if the platform cannot run at the rated frequency.

Black PCB modules without heat spreaders for dense

The low-profile design fits tight DIMM spacing in rackmount or small-form-factor chassis. Gold-edge 288-pin connectors meet JEDEC and RoHS standards, and the kit is tested for warranty-safe upgrades in OEM workstations and servers.

Questions about this item

What comes in the OWC 16GB DDR4 2666MHz ECC kit and is anything else required?

The package contains two 8GB 288-pin UDIMM modules for a total of 16GB. No extra parts are needed if your motherboard has two free DDR4 slots.

Should I pick the 16GB dual-channel kit or a different capacity for my workstation?

This 16GB (2x8GB) kit runs at 2666MHz CL19 and is designed for workstations, servers and NAS units that support ECC unbuffered memory.

What does the 2666MHz rating mean once the RAM is installed in my system?

The modules operate at 2666MHz with CL19 latency at 1.2V and will also run at 2133MHz or 2400MHz if the platform requires a lower speed.
