Capacity 16GB (2 x 8GB)

  • ECC registered design protects data integrity in servers
  • 16 GB kit (2 × 8 GB) expands Cisco UCS capacity
  • DDR3L 1333 MHz CL9 matches system specification
  • 35 V low voltage reduces power draw
  • Validated replacement for Cisco part numbers N01M308GB2, UCSMR1X082RXA, UCSMR2X082RXB, UCSMR2X082RXC

Targeted Server Upgrade

This OWC kit delivers 16 GB of DDR3L 1333 ECC registered memory in a matched pair of 8 GB modules. It is built for Cisco UCS B200 M1 and C200 M1 servers that require 240-pin RDIMMs with CL9 timing and 1.35 V operation. The registered design and 2Rx4 organisation ensure signal integrity in multi-DIMM configurations.

Replaces Cisco OEM Parts

The kit directly replaces Cisco part numbers N01M308GB2, UCSMR1X082RXA, UCSMR2X082RXB and UCSMR2X082RXC. It is the correct choice when a service tag or memory configurator calls for PC3L-10600 registered ECC modules. The jump is worth it when the existing slots are populated with smaller RDIMMs or when a failed OEM stick must be swapped for a validated equivalent.

Capacity and Headroom

Two 8 GB modules fill a dual-channel pair, giving 16 GB of error-correcting capacity for virtualisation hosts, database tiers or NAS workloads. The registered buffer allows further expansion up to the platform’s slot limit without electrical loading issues. It runs out when the application demands exceed the 1333 MT/s bus or when the server’s maximum supported density per socket is reached.

Questions about this item

Will the 240-pin DDR3L RDIMM modules fit the memory slots in my Cisco UCS B200 M1 or C200 M1 server?

Yes, the kit uses the 240-pin DDR3L RDIMM form factor specified for the Cisco UCS B200 M1 and C200 M1, so the modules seat directly in the server's DIMM slots.

What is the correct installation sequence for the two 8 GB registered DIMMs, and what step is commonly missed?

Install the modules in the slot order defined by the Cisco UCS B200 M1 or C200 M1 memory population guide, and ensure each registered DIMM clicks fully into place so the ECC registered buffer initialises correctly.

When should I expect to replace these DDR3L 1333 ECC registered modules in a Cisco UCS server?

Replace them only if a module fails or if you upgrade the Cisco UCS B200 M1 or C200 M1 to a platform that requires a different memory generation or capacity.
