64GB DDR4 3200 ECC RDIMM Server Memory

This single 64GB module delivers DDR4 3200 speed with ECC and registered buffering for server and workstation platforms. It uses a 2Rx4 organisation and runs at the standard 1.2V. The 288-pin DIMM fits DDR4 slots that support registered memory. It is built for administrators who need high-capacity error-correcting memory in validated configurations.

Upgrade from lower-capacity or non-ECC DDR4 modules

Replacing smaller RDIMMs with this 64GB stick increases total memory without adding slots, useful when the system has a limited number of DIMM sockets. The jump is worth it when workloads exceed the capacity of existing modules or when unbuffered memory causes stability issues under sustained load. Systems that already run registered ECC at 3200MHz gain capacity without changing speed or voltage.

DDR4 registered DIMM constraints

Registered DIMMs require a memory controller that supports buffering; they will not work in platforms limited to unbuffered UDIMMs. The 2Rx4 density may exceed the rank-per-channel limit on some older DDR4 server boards, preventing the module from being recognised. Mixing registered and unbuffered memory is not supported. Verify the motherboard or system manual for maximum rank count and registered DIMM support before installation.

Questions about this item

Does the 288-pin DDR4 DIMM fit a standard server RDIMM slot?

Yes, the module uses the 288-pin DDR4 DIMM form factor required by registered server memory slots.

What BIOS setting should be checked after installing this 2Rx4 registered ECC module?

Verify that the memory channel runs at 1.20 V and that ECC is enabled so the 2Rx4 organisation is recognised.

When should this 64 GB DDR4 3200 module be replaced?

Replace it if system logs report uncorrectable ECC errors or if memory diagnostics show persistent failures.
