8GB DDR4 2666 ECC Registered DIMM

This A-Tech module is an 8 GB DDR4 2666 ECC RDIMM built for servers and workstations that require registered memory with error correction. It uses a 288-pin form factor, operates at 1.2 V with CL19 latency, and is organised as 2Rx8 dual-rank chips. The module is designed to boost loading speeds and system responsiveness in compatible enterprise platforms.

Suited for DDR4 registered ECC systems only

It suits administrators upgrading or repairing DDR4 servers and workstations that explicitly support ECC RDIMM modules. It will not work in desktop PCs, laptops, or any system that requires unbuffered non-ECC memory, so buyers with consumer hardware should look elsewhere.

Registered ECC RDIMM with 2Rx8 organisation

The single specification that decides fitment is the registered ECC RDIMM design with 2Rx8 organisation; only systems qualified for DDR4 2666 registered ECC DIMMs can accept this module.

Questions about this item

Does the 288-pin DDR4 RDIMM fit my server's registered DIMM slots?

This module uses the standard 288-pin DDR4 RDIMM form factor, so it fits any server or workstation slot designed for registered DDR4 memory.

What is the correct way to seat the 2Rx8 registered module in a multi-channel server?

Align the notch with the slot key, press firmly until both retention clips click, and follow your system manual for the proper channel population order.

When should I consider replacing this 1.2V ECC RDIMM?

Replace the module if your server logs corrected ECC errors that become uncorrectable, or if memory diagnostics report persistent faults after reseating.
