OWC 32GB DDR3L 1333 ECC Registered Kit

This OWC kit provides 32GB of DDR3L memory as four 8GB registered DIMMs. Each module runs at 1333MHz with CL9 latency and operates at 1.35V. The 240-pin RDIMMs include ECC and registered buffering for data integrity. They are validated for the Cisco UCS B230 M1 server platform.

Suited for Cisco UCS B230 M1 upgrades

This memory suits administrators upgrading or repairing a Cisco UCS B230 M1 server. It will not work in standard desktop PCs or consumer laptops. Builders needing unbuffered DIMMs or load-reduced modules should look elsewhere. Mixing with non-registered memory is not supported by the platform.

Registered ECC DDR3L 1.35V specification

The registered ECC design with 1.35V DDR3L signalling is the single specification that decides compatibility. The Cisco UCS B230 M1 requires this exact combination of buffering, error correction and low voltage. Modules lacking registration or ECC will not function in this system.

Questions about this item

Is the 32GB kit the only capacity offered for this DDR3L 1333 ECC Registered RDIMM?

The listing shows a single 32GB kit built from four 8GB modules. No other capacities are mentioned for this part number.

What does the PC3L-10600 1333MHz CL9 rating deliver in a Cisco UCS B230 M1 server?

It runs at 1333 MT/s with CL9 latency at 1.35V, providing ECC error correction and registered buffering for stable server workloads.

Does the 240-pin DDR3L interface limit the maximum speed or voltage compared with standard DDR3?

The modules operate at 1.35V and 1333 MT/s, which is the rated speed for PC3L-10600; the 240-pin form factor fits the B230 M1 memory slots.
