16GB DDR4 ECC RDIMM for Cisco Servers

This 16GB registered DIMM runs at 2133MHz with CL15 latency and 1.20V operation. It uses a 2Rx4 organisation and major-brand chips to deliver error-correcting memory for compatible Cisco UCS platforms. The module is a direct replacement for part numbers UCS-MR-1X162RU-A and 15-102216-01.

Verify DDR4 RDIMM Support and Slot Population

Confirm that your server accepts DDR4 registered ECC DIMMs at 2133MHz before ordering. Check the system documentation for maximum capacity per slot and the supported rank configuration. Ensure the memory controller can address 2Rx4 modules and that the available 288-pin slots match the required form factor.

Registered Design with 288-Pin DIMM Interface

The registered buffer reduces electrical load on the memory controller for stable operation in multi-module configurations. A 288-pin DDR4 DIMM keying prevents insertion into incompatible slots. ECC circuitry corrects single-bit errors to protect data integrity in continuous server workloads. Modules are tested for dependable performance in qualified systems.

Questions about this item

Does the 16GB DDR4 2133MHz ECC RDIMM ship as a single 288-pin module or must I buy additional sticks?

The item is a single 16GB module (1 x 16GB) with a 288-pin DDR4 DIMM form factor; no extra sticks are included.

Should I choose the 2Rx4 registered version or a different rank for my Cisco UCS-MR-1X162RU-A replacement?

This module matches the Cisco part numbers UCS-MR-1X162RU-A and 15-102216-01 with 2Rx4 organisation, registered ECC, CL15 latency and 1.20V operation.

What does the PC4-17000 rating mean for real-world throughput in a server?

PC4-17000 indicates a peak transfer rate of 17000 MB/s at 2133 MT/s; actual bandwidth depends on the platform's memory controller and channel population.
