16GB DDR3L ECC Registered Kit

This kit provides 16GB of DDR3L 1600 ECC registered memory in a matched pair of 8GB modules. It uses the 240-pin RDIMM form factor and operates at 1.35V with CL11 latency. The modules are built for Lenovo Flex System x280 X6, x480 X6 and x880 X6 servers.

Suits Lenovo Flex System servers

It is designed for administrators upgrading or repairing those specific Lenovo Flex System x6 nodes. It will not work in standard desktop computers or consumer laptops. Buyers needing unbuffered UDIMM memory or a different DDR generation should look elsewhere.

Registered ECC with 1Rx4 organisation

The memory is registered and includes ECC with a single-rank 1Rx4 layout. This combination determines compatibility with the target server memory controllers. Mixing these modules with unbuffered DIMMs is not supported.

Questions about this item

Does the 240-pin DDR3L RDIMM fit the Lenovo Flex System x280 X6, x480 X6 and x880 X6 memory slots?

Yes, the kit is built to the 240-pin DDR3L ECC registered form factor specified for those three Flex System models.

What is the correct installation sequence for the two 8GB 1Rx4 modules in a Flex System x480 X6?

Populate the lowest-numbered DIMM slots for each CPU first, following the server’s slot population guide; the registered design requires matched pairs per channel.

When should the 1.35V ECC registered modules be replaced in a production x880 X6?

Replace them if the system logs uncorrectable ECC errors, if memory diagnostics report persistent failures, or when a planned capacity upgrade requires different rank configuration.
