Supermicro 32GB DDR5 4800 RDIMM

This Supermicro registered DIMM delivers 32GB of DDR5 memory at 4800 MT/s with ECC protection. The module operates at 1.10V and uses a CL40 latency profile. It is built with Hynix components in a 1Rx4 configuration for server platforms.

Suited for servers needing registered ECC memory

This module fits systems that require registered DDR5 RDIMMs with error correction. Workstations or consumer boards that accept only unbuffered non-ECC UDIMMs cannot use this memory. Buyers who need lower latency timings or higher clock speeds should evaluate other modules.

Registered ECC RDIMM with 1Rx4 organisation

The single-rank 1Rx4 layout and registered buffer define compatibility with qualified server motherboards. The DDR5 4800 rating and CL40 latency set the baseline performance envelope. Verify the platform supports registered ECC DDR5 before purchase.

Questions about this item

Does the DDR5 4800 interface cap at PC5 38400 bandwidth?

Yes, the module runs at DDR5 4800 which corresponds to PC5 38400 peak transfer rate.

What slot type and form factor does this 32GB RDIMM need to fit?

It requires a standard DDR5 RDIMM socket; the module is a 1Rx4 registered DIMM.

How is this memory installed and what step is often missed?

Insert the RDIMM into the DDR5 slot until the ejector clips click; the common mistake is not seating both ends fully so ECC registration fails.
