32GB Registered DDR4 Module

This 32GB Samsung DDR4 2400 module uses a 288-pin registered design for server platforms. The 2Rx4 rank configuration and PC4-19200 rating suit multi-socket systems that require registered memory. It is built for environments where data integrity and high capacity per slot are priorities.

Replaces Unregistered Lower-Capacity DIMMs

The jump is worth it when a server board requires registered modules and the current DIMMs limit total memory per channel. Swapping unbuffered sticks for this registered 32GB part enables the larger memory footprints needed for virtualization or database workloads.

Fits 288-Pin DDR4 Registered Slots

Installation requires a motherboard that supports registered DDR4 and accepts 2Rx4 modules. The registered buffer reduces electrical load on the memory controller, freeing headroom for populating additional slots. Systems that only accept unbuffered memory cannot use this module.

Questions about this item

Does this 288-Pin DDR4 module fit a standard 288-pin server DIMM slot?

Yes, the 288-Pin DDR4 form factor matches the standard registered DIMM slot used in compatible servers.

How do I seat the 32GB Registered DDR4 2400 stick so it locks correctly?

Align the notch with the slot key, press down firmly until both side clips snap shut, and verify the module sits evenly.

When should I replace this 2Rx4 Registered DDR4 kit in a production server?

Replace it if ECC logs show rising correctable errors, the system fails memory diagnostics, or a capacity upgrade is required.
