Server Memory Upgrade Kit

This 32 GB kit contains two 16 GB DDR3L ECC Registered RDIMMs built for the Cisco UCS B200 M2. It targets administrators who need to expand capacity in that specific server platform without mixing registered modules with unbuffered or load-reduced memory.

Build Integration

The modules use the 240-pin DDR3L form factor and operate at 1.35 V, so they require a motherboard that supports registered ECC DDR3L at PC3L-10600 speed. They free standard desktop memory slots for other workloads because they are not compatible with consumer boards.

Thermals And Power

Running at 1.35 V reduces power draw compared with standard DDR3 voltage, helping the server’s existing cooling cope with the added capacity. No heat spreaders are fitted, so airflow across the DIMM rows handles thermal management during normal operation.

Questions about this item

What is the maximum capacity this Cisco UCS B200 M2 kit can add to a server?

The kit provides 32 GB total, delivered as two 16 GB DDR3L 1333 registered ECC modules.

How much power do these 1.35 V DDR3L RDIMMs draw compared to standard 1.5 V DDR3?

At 1.35 V the DDR3L modules consume less power and generate less heat than 1.5 V DDR3, helping the server run cooler all day.

Does the B200 M2 need any specific BIOS setting or firmware version to recognise these 2Rx4 registered DIMMs?

The modules are built to JEDEC PC3L-10600 CL9 specs and replace Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC, so they work with the standard server firmware.
