Cisco B200 M2 server upgrade

This kit provides 128GB of DDR3L ECC registered memory in eight 16GB modules built for the Cisco UCS B200 M2 blade server. It is designed for administrators who need to maximise the memory capacity of that specific platform. The modules will not work in standard desktop PCs or in systems that require unbuffered or load-reduced DIMMs. Buyers who need memory for a different server model or a consumer motherboard cannot use this product.

Low-voltage registered operation

Each module runs at 1.35V and 1333MHz with CL9 timings, matching the PC3L-10600 JEDEC standard for reduced power draw in dense blade environments. Registered buffering adds a clock cycle of latency but improves signal integrity when all DIMM slots are populated. The kit has no heat spreaders, relying on the chassis airflow of the B200 M2 for cooling under normal workloads.

Direct Cisco part replacement

The kit replaces Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC, simplifying procurement for existing fleets. OWC includes an advanced replacement programme and lifetime warranty with free technical support for the memory itself. No additional software, cables or mounting hardware are bundled with the modules.

Questions about this item

How do I install the 240-pin DDR3L RDIMMs in the Cisco UCS B200 M2, and what step is often missed?

Power down the blade, open the chassis, align each 240-pin module with the slot key, press firmly until both latches click, then verify all eight 16GB modules are recognised in the BIOS before closing the chassis.

What maintenance or replacement will the 1.35V ECC registered kit need over time?

The modules have no moving parts and no heat spreaders; under normal server airflow they require no scheduled maintenance, and replacement is only needed if a DIMM fails ECC scrubbing or the system reports a correctable-error threshold.

What limit appears first when the 128GB kit runs sustained workloads at 1333MHz CL9?

The registered buffer and 1.35V DDR3L voltage ceiling cap sustained throughput at the rated PC3L-10600 speed; thermal throttling in a fully populated B200 M2 chassis typically becomes the first bottleneck before the memory controller saturates.
