32GB DDR4 2666MHz ECC RDIMM Server Module

This A-Tech module provides 32GB of DDR4 2666MHz registered ECC memory in a single 288-pin DIMM. It runs at 1.20V with CL19 latency and uses a 2Rx4 organisation. The stick is built as a direct replacement for the Crucial CT32G4RFD4266 part number.

Suits servers and workstations needing registered

This module fits systems that require registered DDR4 ECC DIMMs at the 2666MHz speed grade. It is not suitable for desktop boards that accept only unbuffered non-ECC memory, nor for platforms limited to lower speeds or different voltages.

Verify your platform supports DDR4 2666MHz

Check the motherboard or system manual for the maximum supported capacity per slot and the qualified voltage of 1.20V. Confirm the memory controller accepts 2Rx4 registered modules before ordering.

Questions sur cet article

What motherboard slot and chipset are required for this DDR4 2666 ECC RDIMM?

The module uses a 288-pin DDR4 DIMM interface and requires a server or workstation motherboard that supports registered ECC memory at 1.20V.

Can I mix this 32GB 2Rx4 module with existing 1Rx4 or 2Rx8 sticks in the same server?

Mixing ranks is possible only if the platform's memory controller and BIOS allow it; populate identical modules per channel for best stability.

How do I confirm the module is running at 2666MHz with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory speed shows 2666 MT/s and ECC status reports enabled for the new DIMM.
