32 GB DDR4 ECC SO-DIMM for servers

This 32 GB DDR4 2666 MT/s module uses a 260-pin SO-DIMM form factor with ECC and a 2Rx8 organisation. It runs at 1.20 V with CL19 19-19-19 timings and is suited to server platforms that accept unbuffered ECC memory.

Before ordering check your platform

Verify that the system supports DDR4 SO-DIMM slots, 2666 MT/s speed, unbuffered ECC operation and 2Rx8 rank configuration. The motherboard or server documentation must confirm compatibility with these exact specifications before installation.

No bundled accessories or software

The module ships as a standalone memory component without additional cables, adapters or software utilities. Installation relies solely on the host system's memory slots and BIOS or UEFI configuration.

Questions about this item

Does the 32 GB DDR4 2666 SO-DIMM arrive as a single stick or a kit, and are any brackets or cables needed?

The module is supplied as one 32 GB stick; no brackets, cables or extra parts are included.

How do I choose between the 2666 MT/s CL19 2Rx8 version and other speeds or ranks for my server?

Select this 2666 MT/s CL19 2Rx8 module when your platform specifies DDR4 2666 unbuffered ECC SO-DIMM; other speeds or ranks may not be supported.

What does the 2666 MT/s rating mean once the ECC SO-DIMM is installed in a live system?

The memory runs at 2666 MT/s with CL19 timing at 1.20 V, providing error-correcting code protection on each 2Rx8 bank.
