16GB DDR3L 1600 ECC RDIMM

This is a 16GB DDR3L 1600 ECC Registered DIMM built for Cisco UCS servers. It runs at 1.35V with CL11 latency and a 2Rx4 organisation. The module uses a 240-pin form factor and carries major-brand chips. It serves as a direct replacement for Cisco part numbers 15-13615-01, 15-13615-02, 15-101778-01, UCS-MR-1X162RY-A and UCS-MKIT-162RX-C.

Cisco UCS server upgrades

Administrators expanding memory in compatible Cisco UCS platforms will find this module matches the required voltage, rank and ECC configuration. Builders working on consumer desktops, laptops or non-Cisco workstations should look elsewhere because the registered buffer and pin count differ from standard unbuffered DIMMs. Systems requiring unbuffered memory or a different voltage cannot accept this part.

2Rx4 registered organisation

The dual-rank 2Rx4 layout with registered buffering determines whether the server's memory controller can address the module correctly. Verify that your Cisco UCS model supports 2Rx4 RDIMMs at 1600 MHz before ordering.

Questions about this item

Does this module use the standard 240-pin DDR3 DIMM slot or the 262-pin form factor?

The specifications list a 240-pin DDR3 DIMM form factor, which fits standard registered DDR3 server slots.

What is the correct seating procedure for this registered ECC module, and what step is commonly missed?

Align the notch with the slot key, press firmly until both ejector clips click shut, then verify the OS reports the full 16GB at 1600MHz.

When should this 1.35V DDR3L RDIMM be replaced in a 24/7 server environment?

Replace the module if the system logs uncorrectable ECC errors or if memory diagnostics report persistent failures on the 2Rx4 chipset.
