16GB DDR3L ECC RDIMM for Lenovo Flex System

This 16GB DDR3L 1600 registered DIMM is built for Lenovo Flex System x280 X6, x480 X6 and x880 X6 servers. It delivers ECC error correction and registered buffering for stable operation in multi-socket workloads. The module runs at 1.35V with CL11 latency and a 2Rx4 organisation.

Replaces Lenovo 0C19535 46W0671 46W0672

Use this module to replace the listed Lenovo part numbers when expanding or refreshing memory in the compatible Flex System nodes. The upgrade is worthwhile when your workloads need ECC integrity and registered signalling beyond what unbuffered DIMMs provide. It will not work in standard desktop platforms.

Verify DDR3L registered ECC support before ordering

Confirm the target system accepts 240-pin DDR3L registered ECC modules at 1.35V and that you are not mixing with unbuffered memory. Check available DIMM slots and maximum per-channel population rules in the server documentation. This module is not compatible with consumer desktop motherboards.

Questions about this item

Will this 240-pin DDR3L RDIMM fit the DIMM slots in a Lenovo Flex System x280 X6?

Yes, the 240-pin form factor matches the DDR3L slots in the Flex System x280 X6, x480 X6 and x880 X6.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the system recognises the full 16 GB at 1600 MHz.

When should this 1.35 V ECC RDIMM be replaced in a server running 24/7?

Replace it if memory diagnostics report correctable errors that become uncorrectable, or after a firmware update that requires matched 2Rx4 modules.
