16GB DDR4 2666 ECC UDIMM

This 16GB DDR4 2666 ECC UDIMM module is built for servers and workstations that require error-correcting memory. It runs at 1.20V with a 2Rx8 rank configuration on a 288-pin interface. The part is validated as a direct replacement for Lenovo part number 4X70S69156.

Upgrading from non-ECC or lower capacity

Replaces standard unbuffered memory without error correction or smaller 8GB modules when data integrity is required. The jump is worth it when workloads demand ECC protection and the platform supports DDR4 2666 speeds at PC4 21300 bandwidth.

Installing in matched pairs or sets

Installation follows standard UDIMM procedure: align the notch, press until the clips lock, and verify detection in BIOS. Common issues arise when mixing ranks or speeds across channels, so use identically specified modules to avoid training failures.

Questions sur cet article

Will the 288-pin DDR4 module fit my Lenovo server DIMM slots?

Yes, the 288-pin DDR4 UDIMM matches the standard DDR4 slot layout used in compatible Lenovo systems.

What is the correct way to seat the 1.2V ECC UDIMM so the system recognises the full 16GB?

Align the notch with the slot key, press straight down until both retention clips click, and verify the module sits flush with no gap.

When should I expect to replace the 2Rx8 DDR4-2666 memory under normal server workloads?

DDR4 ECC UDIMMs typically run for the life of the platform; replace only if diagnostics report correctable errors rising or a module fails POST.
