Targeted Server Upgrade

This 16 GB DDR3L module is built for Cisco UCS-MKIT-164RX-D and 15-13255-01 systems needing registered ECC memory. It suits administrators expanding capacity in compatible rack or blade servers running virtualization or database workloads.

Registered DIMM Design

The 240-pin RDIMM operates at 1.35 V with a 4Rx4 organisation and CL9 latency at 1333 MHz. Registered buffering reduces electrical load on the memory controller, supporting stable operation in multi-module configurations.

Replaces Original Cisco Kit

This A-Tech part directly substitutes the factory Cisco UCS-MKIT-164RX-D kit when a single 16 GB module is required. The jump is worthwhile when a slot is free and the platform qualifies the 4Rx4 rank structure.

Questions about this item

What does the DDR3L 1333 PC3L 10600 rating cap in practice?

It caps the module at 1333 MT/s with CL9 timing at 1.35 V, so the server memory bus cannot run faster than DDR3 1333.

What physical slot and pin count does this 16 GB ECC RDIMM need?

It fits a standard 240 pin DDR3 DIMM slot; the 4Rx4 registered design also requires a server motherboard that supports quad rank modules.

How is the module installed and which step is often missed?

Align the notch with the key, press firmly until both retention clips click, then verify in BIOS that the system sees 16 GB at 1333 MHz with ECC active.
