48 GB DDR5 6400 registered ECC module

This single 48 GB DDR5 6400 RDIMM delivers registered ECC memory for server platforms that require error correction and signal buffering. It operates at 1.1 V with a CAS latency of 52 and uses a 1Rx4 organisation on a 288-pin form factor. The module is built for enterprise workloads and is not intended for desktop PCs.

Thermals power and noise in normal use

Registered DDR5 modules run at 1.1 V, which keeps power draw low compared to higher-voltage server memory. The RDIMM register reduces electrical loading on the memory bus, helping maintain stable temperatures under sustained throughput. No active cooling is required on the module itself; airflow from standard server chassis fans is sufficient.

Build integration and system impact

The 288-pin RDIMM fits DDR5 server slots that support registered ECC memory and 1Rx4 density. Each module provides 48 GB in a single slot, leaving additional DIMM positions free for further capacity expansion. Systems must support DDR5 6400 registered ECC operation; desktop consumer platforms cannot use this memory.

Questions about this item

How do I install the 288-PIN DDR5 ECC Registered RDIMM and what step is often missed?

Align the notch on the 288-PIN module with the DDR5 slot key, press firmly until both retention clips click, then verify the server BIOS recognises the 48GB 1Rx4 6400MHz module at 1.1V.

What maintenance or replacement will this 48GB DDR5 6400 ECC RDIMM need over its service life?

The module has no user-serviceable parts; if a correctable ECC error count rises or the server reports a persistent memory fault, replace the RDIMM under the lifetime replacement warranty.

What limit appears first when this 1.1V DDR5 6400 1Rx4 RDIMM runs sustained workloads?

The CAS latency of 52 cycles at 6400MHz sets the timing floor; under continuous load the memory controller will hit this latency boundary before thermal or voltage limits are reached.
