Server ECC RDIMM for workstations

This A-Tech 16GB DDR5 6400 ECC RDIMM is a registered server memory module designed for compatible workstation and server platforms. It uses a 1Rx8 organisation with major-brand DRAM ICs and operates at the standard DDR5 voltage of 1.10V. The module serves as a direct replacement for Hynix HMCG78AHBRA and HMCG78AHBRA477N part numbers.

Simple DIMM installation with manual guidance

Installation follows the standard 288-pin DDR5 DIMM procedure: align the notch, press firmly until the retention clips engage, and ensure the module seats evenly. The supplier advises consulting your system manual for proper memory seating and channel population rules, as incorrect slot order is the most common cause of boot failure or reduced performance.

Verify platform support for registered ECC DDR5

Before ordering, confirm that your motherboard and CPU support DDR5 RDIMM modules with ECC and registered buffering, as standard consumer desktop platforms typically do not accept this memory type. Check the qualified vendor list or system documentation for 1Rx8 16GB module compatibility and maximum supported speed to match the 6400 MT/s rating.

Questions about this item

How can I verify the A-Tech 16GB DDR5 6400 ECC RDIMM is running at the correct 6400 speed and CL32 latency after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 6400 MT/s with CAS latency 32; the module operates at the standard 1.10 V, so no manual voltage adjustment is needed.

What is included with the A-Tech 16GB DDR5 6400 ECC RDIMM and do I need any extra parts such as a heat spreader?

The box contains a single 16 GB 288-pin DDR5 RDIMM built with major-brand DRAM ICs; no heat spreader is fitted or required, and no additional cables or brackets are necessary for installation.

Which capacity and rank option should I choose if my server manual specifies 1Rx8 registered ECC modules at 6400 MT/s?

This module provides exactly 16 GB in a 1Rx8 organisation with ECC RDIMM registration, matching the 6400 MT/s PC5-51200 specification your manual calls for.
