32GB DDR4 ECC UDIMM Server Memory

This 32GB DDR4 2666MHz ECC UDIMM module provides error-correcting memory for server and workstation systems. It operates at 1.2V with CL19 latency and uses a 2Rx8 rank configuration on a 288-pin DIMM form factor.

Suits ECC unbuffered DDR4 platforms only

This module fits systems that require DDR4 ECC UDIMM memory at 2666MHz. It is not for platforms that need registered DIMMs, non-ECC memory, or a different DDR generation or speed.

32GB capacity in a single 2Rx8 module

The 32GB density in one 2Rx8 DIMM determines whether your system's memory slots and chipset support this configuration. Verify the maximum capacity per slot and rank limits before purchase.

Questions about this item

Will this 32GB DDR4 2666MHz ECC UDIMM run reliably alongside existing 1.2V DDR4 modules in my server?

Yes, it operates at the standard 1.2V DDR4 voltage and matches the 2666MHz speed, so it can work with other DDR4 2666 1.2V UDIMMs if your platform supports mixed capacities and ranks.

How can I verify the ECC function is active after installing this 2Rx8 CL19 module?

Check the BIOS or UEFI memory information screen for ECC enabled status, and confirm the operating system reports the full 32GB capacity with error-correction active.

Does the single 288-pin DIMM ship with any brackets or cables, or is it just the memory module?

Only the 32GB DDR4 2666MHz ECC UDIMM module is included; no brackets, cables or additional hardware are supplied.
