Axiom 8GB DDR4-2666 ECC UDIMM for Lenovo

SKU CH-3V5Y-TFRJT

An 8 GB DDR4-2666 ECC UDIMM that adds error-correcting memory capacity to compatible Lenovo systems

  • ECC protection maintains data integrity for critical workloads
  • DDR4 architecture delivers 30% faster single-DIMM performance over DDR3
  • 2666 MHz speed enables responsive application loads
  • 8 GB capacity allows more programs to run simultaneously
  • 20% lower power consumption reduces cooling demands

8GB DDR4-2666 ECC UDIMM

This 8GB DDR4-2666 ECC UDIMM is built for Lenovo systems requiring error-correcting memory. It suits workstations and servers where data integrity is essential. The unbuffered design fits standard desktop and entry-level server boards. Buyers needing registered DIMMs or higher densities should look elsewhere.

Capacity and headroom

The 8GB module allows more programs to run simultaneously in single-DIMM configurations. DDR4 delivers up to 30% better performance over DDR3 in this setup. In 3-DIMM-per-channel arrangements the gain scales to 65%. Component densities are 300% higher than the previous generation. Speed doubles with a 100% increase in data rate.

Build fit and freedoms

Lower voltage cuts power draw by 20%, reducing cooling load and freeing thermal headroom. Improved signal integrity and RAS features support longer uptime in enterprise workloads. The UDIMM form factor drops into compatible Lenovo slots without extra hardware. Systems limited to registered memory cannot use this module.

Questions about this item

Will this 2666 MHz DDR4 ECC UDIMM run reliably alongside older DDR3 modules I still have installed?

No, DDR4 and DDR3 use different key notches and voltages, so they cannot share the same motherboard slots.

How can I confirm the module is operating at 2666 MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as CPU-Z; both will report the running frequency and ECC status.

Does the 8 GB stick ship with any extra parts or do I need to buy a heatsink separately?

Only the UDIMM itself is included; no heatsink, tools or additional cables are supplied.
