Server memory kit

This 32 GB kit contains four 8 GB DDR3L 1333 ECC registered RDIMMs built for Cisco UCS B440 M1 and C460 M2 systems. It runs at 1.35 V with CL9 latency and a 2Rx4 organisation. The modules are designed for workstation and server platforms that require registered error-correcting memory.

Registered ECC difference

Registered buffering and ECC let the memory controller manage larger capacities and detect single-bit errors without involving the CPU. The kit replaces Cisco part numbers N01M308GB2, UCSMR1X082RXA, UCSMR2X082RXB and UCSMR2X082RXC. It cannot be mixed with unbuffered or load-reduced DIMMs.

Compatibility check

Verify that your system board accepts 240-pin DDR3L registered ECC modules at 1.35 V and that the BIOS supports 8 GB dual-rank DIMMs. Standard desktop boards and consumer laptops will not post with this memory. Buyers who need unbuffered or non-ECC modules should look elsewhere.

Questions about this item

Will the registered DIMMs need any firmware updates or periodic reseating in a Cisco UCS B440 M1?

No firmware updates or scheduled reseating are required; the modules are validated for the B440 M1 and C460 M2 and run at the JEDEC-standard 1.35 V.

What thermal or power limit appears first when all four 8 GB modules run continuously at 1333 MHz?

Each module draws 1.35 V at DDR3L 1333 speeds with no heat spreader, so the platform’s DIMM-slot airflow limit is reached before any module-level throttle point.

How much fan noise and heat should I expect from the 32 GB kit under 24/7 server load?

The kit operates at the standard 1.35 V DDR3L voltage without heat spreaders, so thermal output and acoustic impact match the baseline for registered DDR3L 1333 modules in the supported Cisco chassis.
