System Specific DDR4 Upgrade

This Axiom 32GB module targets Lenovo systems requiring DDR4 2133 memory with error correction. It operates at 1.20V with a CAS latency of CL15 and uses the standard 288-pin DDR4 SDRAM form factor.

Suited for ECC Lenovo Platforms

Administrators maintaining compatible Lenovo servers or workstations that mandate ECC registered memory will find this module appropriate. Builders assembling custom PCs, upgrading consumer laptops, or populating non-ECC platforms should look elsewhere because the error correction and system-specific validation target a different hardware class.

Lifetime Warranty and OEM Validation

The supplier bundles a lifetime warranty and guarantees compatibility through its OEM Alternative programme. This assurance replaces the need for separate qualification testing and provides a direct replacement path if a module fails verification in the approved Lenovo system.

Questions about this item

What motherboard slot and voltage does this 288-pin DDR4 module need?

It installs in a standard 288-pin DDR4 DIMM slot and runs at 1.20 V.

Will this ECC DDR4 2133 module run in a Lenovo system that currently uses DDR3?

No. DDR4 and DDR3 use different keyed slots and signalling, so the module cannot be used in a DDR3 platform.

How can I confirm the 32 GB stick is running at CL15 and 2133 MT/s after installation?

Check the memory tab in CPU-Z or the BIOS SPD readout; they will show DDR4-2133, PC4-17000 and CAS latency 15.
