Axiom 16GB DDR4-2666 ECC UDIMM

This Axiom server memory module delivers 16 GB of DDR4 capacity with ECC error correction for data integrity. It operates at 2666 MHz with a low 1.20 V requirement. The unbuffered 288-pin UDIMM form factor suits compatible Lenovo server platforms.

Sustained load behaviour

DDR4 architecture provides up to 30% performance improvement for single DIMM configurations and scales up to 65% faster in 3-DIMM per channel applications over DDR3. Lower voltage reduces power consumption by 20%, easing cooling demands during continuous operation.

Compatibility check

Verify your Lenovo server accepts 288-pin UDIMM modules at the PC4-21300 data rate with x72 width and ECC support. Systems requiring registered or load-reduced DIMMs cannot use this unbuffered module. Buyers needing higher densities or different form factors should confirm platform specifications first.

Questions about this item

How much heat and power draw does the 1.20 V DDR4-2666 ECC UDIMM add when the server runs continuously?

The module operates at 1.20 V, delivering a 20% decrease in power consumption compared with DDR3, which reduces the cooling load during all-day operation.

What motherboard slot and memory controller features are required to use this 288-pin PC4-21300 ECC UDIMM?

A DDR4-capable motherboard with a 288-pin UDIMM slot and an integrated memory controller that supports ECC unbuffered operation at 2666 MT/s is required.

Will this 16 GB x72 DDR4 ECC UDIMM work reliably alongside older DDR3 DIMMs still installed in the same server?

No, DDR4 and DDR3 use different pin counts, voltages and signalling; they cannot be mixed in the same system.
