16 GB DDR4 ECC Registered Module

This 16 GB DDR4 module runs at 2133 MT/s with a CAS latency of CL15. It is built as a 2Rx4 registered DIMM with ECC for error correction. The stick operates at 1.20 V and fits the standard 288-pin DDR4 slot.

Registered Design for Server Boards

The registered buffer reduces electrical load on the memory controller, allowing stable operation in multi-DIMM server configurations. ECC circuitry detects and corrects single-bit errors to protect data integrity. This module targets Dell systems that require registered memory.

Low-Voltage Operation and Thermals

Running at 1.20 V keeps power draw modest for dense memory populations. The registered design and ECC logic add minimal latency overhead in normal workloads. No active cooling is required on the module itself.

Questions about this item

What DDR4 speed does this PC4 17000 module run at and what bandwidth does that standard cap?

The module runs at DDR4 2133, which corresponds to the PC4 17000 standard and caps theoretical bandwidth at 17000 MB/s.

What physical slot and pin count does this 288-pin registered DIMM require?

It requires a standard 288-pin DDR4 DIMM slot; the registered design adds a buffer so the motherboard must support registered memory.

How is this 2Rx4 ECC registered kit installed and what common step is missed?

Install in matched pairs per the server's population rules, seat firmly until the retention clips click, and enable ECC in the BIOS — the step often missed.
