16GB DDR4 ECC Registered DIMM

This 16GB DDR4 module uses a 288-pin DIMM form factor with ECC and registered signal buffering. It is built for servers and workstations that require error correction and signal integrity across high-density memory configurations.

2Rx8 organisation with 288-pin interface

The dual-rank 2Rx8 layout allows higher density per channel while the 288-pin edge connector fits standard DDR4 DIMM sockets. Registered buffering reduces electrical load on the memory controller, supporting stable operation in multi-module populations.

PC4-3200 speed rating

Rated at PC4-3200, this module delivers a 3200 MT/s data rate. Buyers needing a different speed grade or non-ECC unbuffered memory for consumer platforms should select an alternative part.

Questions about this item

Does the PC4-3200 DDR4 interface limit the maximum transfer rate of this registered DIMM?

The PC4-3200 rating indicates the module is validated for 3200 MT/s data transfers, which sets the practical speed ceiling for this 288-pin DDR4 RDIMM.

What physical clearance does the 288-pin DDR4 DIMM need to seat in a server or workstation board?

The module follows the standard 288-pin DDR4 DIMM form factor, so it requires a full-height RDIMM slot with the matching key notch and enough vertical space for the registered buffer components.

How is this Hynix RDIMM installed, and which step is most often missed?

Align the notch on the 288-pin edge connector with the slot key, press down firmly until both side latches click shut, then verify the system recognises the full 16 GB capacity and ECC function in BIOS or OS.
