16GB DDR4 Registered ECC Module

This 16GB DDR4 2133MHz registered ECC memory module is built for select Dell workstations. It uses a 240-pin DIMM form factor and operates at PC4 17000 speed. The module adds error-correcting capacity to supported systems.

Suited for compatible Dell workstations

Builders upgrading a supported Dell desktop that requires registered ECC DDR4 will find this module a direct fit. Systems needing unbuffered non-ECC memory or a different pin count cannot use this part.

16GB capacity for registered ECC workloads

The single 16GB stick provides a solid base for memory-intensive tasks on compatible platforms. Workstations requiring higher total capacity will need additional modules of the same specification.

Questions about this item

Does my Dell desktop need a 240-pin DDR4 slot to accept this 16GB module?

Yes, the module is a 240-pin Registered ECC DDR4 DIMM and requires a compatible DDR4 slot on the motherboard.

Will this 2133MHz Registered ECC DDR4 module run at the correct speed if I keep slower DDR4 DIMMs installed?

The system will clock all installed DDR4 memory to the lowest common speed, so this 2133MHz module will downclock to match slower DIMMs.

How can I confirm the module is detected as 16GB of Registered ECC DDR4 after installation?

Check the BIOS memory information or the operating system task manager; both should report 16GB capacity, DDR4 type, 2133MHz speed and ECC status.
