Server-grade DDR5 capacity

This 48GB DDR5 6400 module delivers PC5-51200 bandwidth with CL52 latency at 1.1V. It uses a 1Rx4 registered ECC design on a 288-pin RDIMM form factor for error-correcting stability in multi-DIMM server channels.

Suited for registered-ECC platforms only

It fits servers and workstations that require registered DDR5 with on-die ECC. Builders of standard desktop PCs or consumer laptops cannot use this memory because those platforms lack the registered buffer and ECC support this module depends on.

Build integration notes

The module occupies a single 288-pin DDR5 slot and draws 1.1V, leaving adjacent slots free for additional registered DIMMs. Its registered architecture reduces electrical load on the memory controller, allowing larger total capacities per channel without extra buffering hardware.

Questions about this item

What motherboard slot and voltage does this 48 GB DDR5 6400 module require?

It installs in a 288-pin DDR5 RDIMM socket and runs at 1.1 V, so the platform must support registered DDR5 at that voltage.

Can I mix this 1Rx4 registered ECC module with older registered ECC DIMMs of different rank or speed?

Mixing ranks or speeds is not recommended; the memory controller will default to the lowest common speed and may disable multi-rank optimisations.

How can I verify the module is running at 6400 MT/s with CL52 after installation?

Check the BIOS memory information or a tool such as dmidecode; it should report 6400 MT/s, CAS latency 52, 1.1 V and registered ECC operation.
