64GB DDR4-2400 Registered ECC Module

This 64GB DDR4-2400 LP ECC TSV RDIMM provides high-density registered memory for server platforms. It operates at 2400 MT/s with a 1.20V voltage and uses a 288-pin form factor. The module is Supermicro certified and built with 4Rx4 rank organisation.

Suited for multi-socket servers needing maximum

The 4Rx4 configuration delivers 64GB in a single low-profile module, ideal for dense memory populations. Systems that require unbuffered UDIMMs or non-ECC memory cannot use this registered ECC RDIMM. Buyers needing lower capacities or different rank structures should consider alternative modules.

TSV stacking enables the 64GB density

Through-silicon via technology allows the high capacity without increasing module thickness, preserving airflow in tight chassis. RoHS compliance confirms restricted substance adherence. No additional accessories, cables or software licences are included with the memory module.

Questions about this item

Does my motherboard need 288-pin DDR4 slots that support registered ECC memory to use this 64GB 4Rx4 module?

Yes, this is a 288-pin DDR4 RDIMM with ECC and registered buffering, so the board must provide DDR4 slots that accept registered ECC DIMMs.

Will the memory controller run at 2400 MT/s if I install this module alongside slower DDR4 DIMMs?

The module is rated for DDR4-2400 (PC4-19200); when mixed with slower DDR4 DIMMs the controller will drop all modules to the lowest common speed.

How can I confirm the system sees the full 64GB capacity and ECC function after installation?

Check the BIOS memory summary or OS tools such as dmidecode — both should report 64GB at 2400 MT/s with ECC enabled.
