8 GB Registered DDR4 Module

This single 8 GB DDR4 module operates at 2400 MT/s with a CL17 latency and 1.20 V supply. It uses a 288-pin RDIMM form factor and a 1Rx8 organisation. The module is built for server platforms that require registered memory.

Suited for registered-DDR4 servers

The stick fits servers that accept registered DDR4 RDIMMs at 2400 MT/s. It is not for systems that need error-correcting code memory, nor for desktop or laptop boards that only support unbuffered DIMMs. Buyers who need ECC protection or higher capacities should look at other modules.

Registered RDIMM form factor

The registered buffer is the specification that decides compatibility. Only motherboards designed for registered DDR4 RDIMMs can use this module; unbuffered consumer boards cannot.

Questions about this item

Will the 288-pin DDR4 module fit my server's registered DIMM slots?

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

How do I install this 1Rx8 registered module correctly?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the motherboard supports registered memory.

Does this 8GB DDR4 2400 module require any firmware updates or battery replacements over time?

No, DDR4 memory modules have no firmware or batteries; they operate passively once installed in a compatible system.
