Cisco UCS server upgrade kit

This 64 GB kit contains eight 8 GB DDR3L 1333 ECC registered RDIMM modules built for Cisco UCS B230 M2 and C260 M2 servers. It targets administrators who need to maximise memory capacity in those specific platforms without mixing buffered and unbuffered DIMMs.

Capacity and headroom

Eight dual-rank 2Rx4 modules deliver 64 GB total at PC3L-10600 CL9 1.35 V, filling the supported slots on the listed UCS models. The registered design and ECC correction keep data integrity intact under sustained workloads, while the DDR3L voltage reduces power draw compared to standard DDR3.

Build integration

Modules use the 240-pin DDR3L form factor and require a motherboard that accepts ECC registered memory; they will not work in standard desktop boards or alongside unbuffered or load-reduced DIMMs. The kit replaces Cisco part numbers N01M308GB2, UCSMR1X082RXA, UCSMR2X082RXB and UCSMR2X082RXC, freeing procurement from sourcing individual OEM sticks.

Questions about this item

Will the 1.35 V DDR3L 1333 RDIMMs run reliably alongside existing 1.5 V DDR3 modules already in my Cisco UCS B230 M2?

No. The kit is 1.35 V DDR3L registered ECC; mixing it with 1.5 V DDR3 unbuffered or registered DIMMs violates the voltage and buffer rules and will prevent the server from posting.

How can I confirm the 64 GB (8 × 8 GB) kit is recognised at 1333 MHz CL9 after installation?

Enter the Cisco UCS BIOS or UEFI, open the memory information screen and verify that all 8 slots show 8 GB each, running at 1333 MT/s with CL9 timings and ECC enabled.

Does the box contain only the eight 240-pin RDIMMs, or are any tools or cables included?

The package supplies the eight 8 GB DDR3L 1333 CL9 2Rx4 1.35 V registered DIMMs only; no installation tools, cables or additional hardware are bundled.
