A-Tech 32GB DDR5 6400 ECC RDIMM

This A-Tech module is a 32GB DDR5-6400 registered DIMM with ECC and a 2Rx8 organisation. It runs at the standard 1.10V and carries a CAS latency of 32. The 288-pin form factor is built for server and workstation platforms that require registered memory.

Suited for registered DDR5 servers only

The stick targets administrators upgrading or repairing systems that specifically call for a registered ECC DIMM at this speed and density. It will not work in platforms that accept only unbuffered UDIMMs or SODIMM form factors, and it cannot be mixed with non-ECC modules in the same channel.

2Rx8 registered ECC at DDR5-6400

The 2Rx8 registered ECC configuration at 6400 MT/s is the single specification that determines whether this module matches the motherboard’s qualified vendor list. Verify that your system supports registered DDR5 with this rank structure and data rate before ordering.

Questions about this item

Will this 32GB DDR5 6400 ECC RDIMM run alongside my existing DDR5 server memory?

This module uses DDR5 6400 (PC5-51200) at 1.10V with CL32 latency and a 2Rx8 registered layout. For stable operation, match those specifications and follow your system manual for channel population rules.

How can I confirm the A-Tech 32GB DDR5 6400 ECC RDIMM is working as intended after setup?

The BIOS should report a single 32GB DDR5-6400 registered ECC module at 1.1V with CL32 timing. Run a memory diagnostic such as MemTest86 to verify error-free operation under load.

What is included with the A-Tech 32GB DDR5 6400 ECC RDIMM and what must be bought separately?

The box contains one 32GB 288-pin DDR5 RDIMM module. No heat spreader, cables, or additional hardware are included; compatible DDR5 server slots are required.
