Server-specific 128GB DDR3L kit

This OWC kit provides 128GB of DDR3L ECC registered memory across eight 16GB modules. It runs at 1333MHz with CL9 latency and operates at 1.35V. The modules are built for Cisco UCS B230 M2 and C260 M2 servers and use the 240-pin RDIMM form factor with 2Rx4 organisation.

Replaces Cisco A02M316GB1L and UCSMR part numbers

The kit directly replaces Cisco part numbers A02M316GB1L, UCSMR1X162RXA, UCSMR2X162RX and UCSMR2x162RXC. It is designed for workstations, servers, NAS systems and routers that require registered ECC DDR3L memory. The upgrade is not compatible with standard desktop computers or systems that use unbuffered or load-reduced DIMMs.

Verify registered ECC support and DDR3L voltage

Check that your server platform accepts registered ECC RDIMMs and supports the 1.35V DDR3L standard before ordering. Mixing these modules with unbuffered or load-reduced memory will prevent operation. The kit contains eight modules, so confirm the target system has enough available 240-pin slots to accommodate the full 128GB configuration.

Questions about this item

Does the 240-pin DDR3L form factor fit the DIMM slots on my Cisco UCS B230 M2 or C260 M2?

Yes, these 240-pin DDR3L RDIMMs are built to the JEDEC DDR3L specification and match the slot layout used in the Cisco UCS B230 M2 and C260 M2 servers.

What is the correct way to install the eight 16 GB modules, and what step do people often miss?

Populate all eight slots in matched pairs per channel, ensure each module clicks fully into the 240-pin socket, and enable ECC registered mode in the BIOS — skipping the BIOS setting is the common error.

When will the 1.35 V ECC registered RDIMMs need replacement or maintenance?

The modules have no moving parts and require no scheduled maintenance; replace only if a memory test reports correctable errors that exceed the ECC threshold or a module fails completely.
