Cisco UCS Server Memory Kit

This kit supplies 16 GB of DDR3L ECC registered memory in two 8 GB modules for Cisco UCS B440 M1 and C460 M2 servers. The modules run at 1333 MHz with CL9 latency at 1.35 V. They are designed for workloads that require error correction and registered buffering.

240-Pin Registered DIMM Format

Each module uses the 240-pin RDIMM form factor with a 2Rx4 organisation and no heat spreader. The registered design reduces electrical load on the server memory controller, allowing stable operation in multi-DIMM configurations. Mixing with unbuffered or load-reduced ECC memory is not supported.

Replaces Cisco N01M308GB2 Series

This upgrade replaces Cisco part numbers N01M308GB2, UCSMR1X082RXA, UCSMR2X082RXB and UCSMR2X082RXC. It suits administrators extending the service life of existing B440 M1 or C460 M2 platforms. Buyers needing higher capacities per slot or different DDR generations should verify platform limits before ordering.

Questions about this item

Does this DDR3L 1333 kit run at the full PC3L-10600 data rate in a Cisco UCS server?

Yes, the modules are rated for DDR3L 1333 (PC3L-10600) CL9 at 1.35 V, so they operate at that speed when the platform supports it.

Will these 240-pin registered DIMMs fit the memory slots in a Cisco UCS B440 M1 or C460 M2?

They are built to the 240-pin DDR3L RDIMM form factor specified for the Cisco UCS B440 M1 and C460 M2, matching the physical slot and keying.

What is the correct way to install the two 8 GB modules, and what mistake should I avoid?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until the ejector tabs click, and do not mix these registered DIMMs with unbuffered or load-reduced memory.
