8GB DDR4 2666MHz ECC UDIMM Server Module

This A-Tech 8GB DDR4 2666MHz ECC UDIMM is a 288-pin server memory module designed to replace Hynix HMA81GU7AFR8N-VK, HMA81GU7CJR8N-VK and HMA81GU7DJR8N-VK parts. It operates at 1.20V with CL19 latency and uses a 1Rx8 unbuffered configuration with major brand chips. The module provides error-correcting code reliability for compatible server and workstation platforms.

Suits ECC UDIMM Slots Only Not Registered Systems

This module suits servers and workstations that require DDR4 2666MHz ECC unbuffered DIMMs in a 1Rx8 layout. It will not work in systems that demand registered or load-reduced memory, nor in platforms limited to non-ECC consumer modules. Buyers needing higher capacities per slot or registered ECC RDIMM support should verify their motherboard specifications before ordering.

1Rx8 ECC Unbuffered Organisation Decides Fit

The single-rank 1Rx8 ECC unbuffered organisation is the specification that determines whether this module installs correctly. Many server boards accept only registered DIMMs or specific rank configurations, so confirming 1Rx8 UDIMM support in the system manual is essential. Without that match the module will not post or will run in a reduced mode.

Questions sur cet article

How can I confirm the module is running at 2666 MHz with CL19 after installation?

Check the memory speed and CAS latency in your system BIOS or a tool like CPU-Z; they should show DDR4-2666 and CL19 when the module is seated correctly.

What comes in the package and do I need any extra parts to install it?

The box contains one 8 GB DDR4 288-pin UDIMM; no cables, brackets or additional hardware are required for a standard DIMM slot.

Which version should I choose if my server requires a 1Rx8 ECC unbuffered DIMM at 1.2 V?

This single 8 GB 1Rx8 ECC UDIMM matches that exact specification, so select this module for a direct replacement.
