Capacity and purpose

This kit provides 48 GB of DDR5 server memory in two 24 GB registered DIMMs. It is built for systems that require ECC error correction and registered signalling at 6400 MHz.

Registered design and daily use

Each module uses a 2Rx8 organisation and runs at 1.1 V through the standard 288-pin RDIMM connector. The registered buffer reduces electrical load on the memory controller, which helps stability in multi-DIMM server configurations.

Upgrade path and fit

The kit replaces slower DDR5 RDIMM sets or smaller-capacity registered modules in compatible platforms. The jump is worthwhile when workloads need both higher bandwidth and ECC protection without exceeding the voltage envelope.

Questions about this item

What speed does the DDR5 6400MHz PC5-51200 interface run at in this kit?

The kit operates at 6400MHz with a PC5-51200 rating and CAS latency 52.

What physical slot and pin count do these modules require?

They use a 288-pin RDIMM form factor for registered DDR5 server slots.

How do I install the two 24GB sticks and what step is often missed?

Insert each module into matching DDR5 RDIMM slots until the ejectors click, then verify ECC registered mode is enabled in BIOS.
