128GB DDR5-5600 ECC Registered RDIMM

This 128GB DDR5 module runs at 5600 MT/s with CL46 latency and 1.1V operation. It uses a 288-pin 4Rx4 registered ECC design built for Supermicro X13SEI-TF, X13SEM-F, X13SEM-TF, X13SET-G and X13SET-GC motherboards. JEDEC-standard and ROHS-compliant, it targets servers, workstations and NAS systems needing maximum density per slot.

Suited for registered-ECC platforms only

This module fits systems that require registered ECC DDR5 memory and accept 4Rx4 density. It will not work in desktops, laptops or consumer motherboards that take only unbuffered non-ECC or unbuffered ECC DIMMs. Builders needing unbuffered memory or load-reduced DIMMs must choose a different module type.

4Rx4 registered ECC density decides fit

The single 128GB 4Rx4 registered ECC organisation is the specification that determines compatibility. Only motherboards qualified for this rank and register configuration can use the module, so verify the platform supports 4Rx4 registered DDR5 before purchase.

Questions about this item

What comes in the box and do I need any extra cables or brackets?

The box contains one 128GB DDR5 5600 CL46 4Rx4 288-pin 1.1V ECC Registered RDIMM module. No cables or brackets are required for installation.

How do I decide between the listed capacities or versions?

This listing is a single 128GB module (part number 5R6D54R4128G). If you need more capacity, add additional identical modules to the remaining slots on your Supermicro motherboard.

What does the 5600 CL46 rating actually deliver once the DIMM is installed in a server?

The module runs at JEDEC-standard DDR5-5600 with CAS latency 46 at 1.1V, providing ECC error correction and registered buffering for stable operation in compatible Supermicro X13SEI-TF, X13SEM-F, X13SEM-TF, X13SET-G and X13SET-GC systems.
