Axiom 32GB DDR4 ECC DIMM for workstations

This 32 GB DDR4 module runs at 2933 MHz with CL21 latency and ECC error checking. It is built for desktop PCs and workstations that require registered data integrity. The 1.20 V operating voltage matches the DDR4-2933/PC4-23466 standard. Unbuffered signal processing keeps the electrical load light for compatible motherboards.

Straightforward 288-pin installation

The 288-pin DIMM seats in any standard DDR4 desktop slot without tools. Alignment notches prevent backwards insertion, but the motherboard must explicitly support unbuffered ECC memory or the module will not post. Mixing non-ECC sticks disables error correction across all channels. Verify the platform's qualified-vendor list before purchase.

DDR4-2933 bandwidth ceiling and platform limits

The PC4-23466 rating caps throughput at the rated 2933 MT/s; faster DDR4 modules will downclock to this speed. Capacity is fixed at 32 GB per module, so total memory depends on available slots. The stick is validated for the Lenovo P340 Tower ThinkStation Workstation; other systems may need a BIOS update to enable ECC at full frequency.

Questions about this item

How can I confirm the module is running at 2933 MHz with CL21 after installation?

Open the BIOS or a tool such as CPU-Z and verify the reported speed shows 2933 MHz and the CAS latency reads CL21; the SPD table will also list PC4-23466.

What comes in the box and is anything else required to use this memory?

The package contains the 32 GB DDR4 ECC DIMM only; no cables, brackets or additional parts are included and nothing else is needed for installation.

Which capacity and speed version should I choose for a Lenovo P340 Tower ThinkStation Workstation?

This 32 GB DDR4-2933 ECC CL21 288-pin DIMM is the specific part (4X71B32813-AX) validated for that workstation.
