128 GB DDR4-2666 server module

This Axiom module provides 128 GB of DDR4 server memory rated at 2666 MHz. It uses a Load-Reduced DIMM form factor with ECC and Registered signal processing. The part is validated for Lenovo systems carrying the 7X77A01307-AX part number.

For single-socket density upgrades

This part suits administrators who need maximum capacity per slot in a compatible Lenovo platform. It is not for desktop or laptop boards that accept only unbuffered UDIMMs. It is also not for servers that require standard RDIMMs instead of the LRDIMM electrical profile.

DDR4-2666 LRDIMM with ECC

The registered LRDIMM architecture at 2666 MHz is the specification that determines whether this module will function in your system. Verify that your server's memory controller and BIOS support DDR4 LRDIMMs at this speed before purchase.

Questions about this item

Does this 128 GB DDR4-2666 module fit a standard 288-pin LRDIMM slot?

Yes, the module uses the standard LRDIMM form factor with 288 pins, matching the DDR4 server memory slot on compatible Lenovo systems.

What is the correct seating procedure for this registered LRDIMM?

Align the notch with the slot key, press down firmly until both ejector clips click into the side notches; the step often missed is verifying both clips are fully latched.

When should this 2666 MHz ECC LRDIMM be replaced?

Replace the module if the system logs uncorrectable ECC errors, fails memory diagnostics, or no longer passes POST during boot.
