64GB DDR5 5600 ECC RDIMM Server Memory

This 64GB DDR5 5600 ECC RDIMM module is built for servers and workstations that require registered, error-correcting memory. It operates at 1.1V with a CAS latency of 40 and uses a 2Rx4 rank configuration.

DDR5 5600 Registered DIMM Interface Constraints

The DDR5 5600 standard delivers a PC5-44800 data rate on a 288-pin registered DIMM form factor. Systems must support DDR5 RDIMM architecture and the registered buffer; unbuffered or UDIMM slots cannot accept this module.

2Rx4 Rank and ECC Registration Decide Compatibility

The single specification that determines fit is the 2Rx4 registered ECC organisation. Platforms limited to single-rank or non-ECC memory will not post with this module installed.

Questions about this item

Should I pick this single 64GB module or combine multiple sticks for my server?

This is a single 64GB DDR5 5600 ECC RDIMM module; add identical modules to fill your motherboard's channels and reach the total capacity your platform supports.

What does the 5600 MT/s rating deliver in a live server?

The module runs at 5600 MT/s (PC5-44800) with CL40 latency at 1.10V, giving registered ECC bandwidth for multi-threaded workloads and virtualization.

How does the 288-pin DDR5 RDIMM interface limit speed or capacity?

The 288-pin registered DDR5 interface operates at 5600 MT/s with on-module register buffering, allowing the 2Rx4 64GB density per DIMM slot.
