Dell-Compatible 64 GB DDR4 RDIMM

This NEMIX RAM module delivers 64 GB of DDR4 3200 memory in a single registered DIMM. It is built for Dell servers and workstations that require ECC error correction and registered signalling. The 2Rx4 organisation and 1.20 V operation match the platform's native specifications.

Registered ECC limits and DDR4 3200 ceiling

Registered ECC RDIMMs add a clock cycle of buffering, so they only function in motherboards wired for registered memory. The DDR4 3200 (PC4-25600) interface caps bandwidth at the JEDEC standard rate; faster DDR4 or DDR5 modules will not train at higher speeds on this platform.

64 GB single-module capacity headroom

One 64 GB stick fills a single slot, leaving remaining DIMM sockets free for further expansion up to the system's maximum supported memory. Workloads that exceed 64 GB per channel or need higher frequencies will hit the module's density and speed limits.

Questions about this item

Should I pick this single 64GB stick or combine smaller modules?

This module delivers the full 64GB in one 288-pin DDR4 RDIMM, so you occupy only one slot and leave others free for future expansion.

What does the 3200MHz rating actually give me in a Dell server?

At 3200MHz with CL22 latency the module runs at the standard PC4-25600 data rate, providing the bandwidth the platform expects for registered ECC workloads.

Does the RDIMM ECC interface limit speed or capacity on my Dell system?

The registered ECC design adds a clock cycle for signal integrity, letting the memory controller manage the 2Rx4 organization reliably at the rated 1.2V.
