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.
