64 GB DDR5-5600 Registered DIMM

This Kingston KSM56R46BD4PMI-64MDI module delivers 64 GB of DDR5 server memory at 5600 MHz with CL46 latency. Registered signal processing and on-die ECC provide the data integrity required for multi-socket platforms. The 288-pin RDIMM form factor fits standard DDR5 server slots.

For registered-ECC server builds.

Workstations and servers that require registered DDR5 with ECC will use this module directly. Desktop boards and consumer laptops that accept only unbuffered non-ECC memory cannot support the registered signalling. Buyers needing lower-capacity registered sticks or modules with a heat spreader should consider other SKUs.

Registered DDR5 with on-die ECC at 1.10 V

The combination of registered buffering and on-die ECC at 1.10 V is the single specification that determines compatibility. Only platforms designed for DDR5 RDIMMs with on-die error correction can initialise this module. Systems lacking registered-DDR5 support will not POST with it installed.

Questions about this item

What motherboard slot is required for this 288-pin DDR5 RDIMM?

It needs a server motherboard with a 288-pin DDR5 RDIMM slot; the module will only fit that connector type.

Will this registered DDR5-5600 CL46 module run at its rated speed in a system that only supports DDR5-4800?

The module will operate at the lower speed the platform allows; it is compatible with DDR5 systems that run at reduced data rates.

How can I confirm the module is running at DDR5-5600 with CL46 timing after installation?

Check the memory speed and timings in the system BIOS or a hardware-monitoring utility to verify 5600 MHz and 46-45-45 values.
