Target Server Upgrade

This 32GB kit contains four 8GB DDR3L ECC Registered RDIMMs built for the Cisco UCS B440 M2 blade server. It is intended for administrators who need to expand memory capacity in that specific platform. The modules will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced memory types.

Capacity and Headroom

The kit delivers 32GB total across four slots, running at DDR3L 1333 (PC3L-10600) with CL9 latency and a 2Rx4 organisation. It provides headroom for virtualisation workloads and larger datasets within the supported server. Capacity is limited to the 32GB supplied; larger configurations would require additional compatible modules and available DIMM slots.

Thermals and Power

Operating at 1.35V, the low-voltage DDR3L modules draw less power than standard DDR3 equivalents. No heat spreaders are fitted, so airflow through the server chassis manages thermals. The registered buffer adds minimal overhead, keeping power draw and acoustic impact low during normal operation.

Questions about this item

Will these 1.35V DDR3L RDIMMs run alongside existing 1.5V DDR3 modules already installed in my B440 M2?

Mixing 1.35V DDR3L with 1.5V DDR3 is not recommended; the server will default to the higher voltage and may cause instability. For reliable operation, replace all modules with matching DDR3L 1333 CL9 2Rx4 registered DIMMs.

How can I verify the kit is running at PC3L-10600 CL9 with ECC active after installation?

Enter the Cisco UCS BIOS or CIMC interface and confirm memory speed shows 1333 MHz, voltage reads 1.35V, CAS latency is CL9, and ECC status reports enabled across all four slots.

Does the 32GB kit include only the four 8GB RDIMMs, or are heat spreaders and a configuration guide also supplied?

The package contains four 8GB 240-pin DDR3L ECC registered RDIMMs (part 1R3T32R4032S) with no heat spreaders; no printed guide or additional accessories are included.
