Server Memory Kit

This OWC kit delivers 64GB of DDR3L ECC Registered memory across eight 8GB modules. It is built for Cisco UCS B200 M1 and C200 M1 servers that require registered DIMMs with error correction. Standard desktop motherboards cannot use this memory type.

Sustained Operation

Registered buffering and ECC functionality maintain data integrity during continuous server workloads. The 1.35V DDR3L voltage reduces power draw compared to standard DDR3 while running at 1333MHz with CL9 latency. Modules operate without heat spreaders in managed airflow environments.

Compatibility Check

Verify your system is a Cisco UCS B200 M1 or C200 M1 before ordering. This memory cannot be mixed with unbuffered or load-reduced DIMMs. Confirm the platform requires 240-pin DDR3L Registered modules and supports 2Rx4 rank configuration.

Questions about this item

How much power does the 1.35 V DDR3L kit draw when the server runs all day?

Each module operates at 1.35 V, lower than standard DDR3, reducing overall power draw and heat output in the Cisco UCS chassis.

What must the buyer already own for this 8 x 8 GB registered ECC kit to work?

A Cisco UCS B200 M1 or C200 M1 server with free 240-pin DIMM slots that support registered ECC DDR3L memory.

Can these 2Rx4 CL9 modules run alongside older unbuffered DIMMs still installed in the system?

No, registered ECC memory cannot be mixed with unbuffered or load-reduced modules; all slots must use matching registered ECC DIMMs.
