Axiom 8GB DDR4-2666 ECC UDIMM for Synology

SKU CH-8GP2-FAF8G

ECC UDIMM adds 8 GB of DDR4-2666 memory with error correction for Synology systems

  • ECC protection guards data integrity in Synology systems
  • DDR4-2666 speed boosts responsive application loads on data-intensive programs
  • Up to 30 % single-DIMM performance gain over DDR3
  • 20 % lower power consumption reduces cooling demands
  • 100 % speed increase and 300 % density gains enable next-generation performance

Axiom 8GB DDR4-2666 ECC UDIMM

This ECC UDIMM is built for Synology systems that require DDR4-2666 memory with error correction. It targets administrators and home-lab users who need reliable capacity expansion for NAS workloads. The module uses top-grade components validated to meet or exceed OEM specifications.

Upgrade from DDR3 platforms

Moving from DDR3 to this DDR4 module can deliver up to 30 percent better performance in single-DIMM configurations and up to 65 percent faster throughput in three-DIMM-per-channel layouts. The jump is worth it when your NAS runs memory-intensive services such as virtualization, container clusters or large-scale file indexing that stress older memory subsystems.

Capacity headroom for NAS workloads

The 8 GB stick handles typical multi-user file sharing, backup tasks and lightweight virtual machines with comfortable headroom. It runs out when heavy database caching, multiple concurrent VMs or large-scale media transcoding push sustained memory pressure beyond a single module's capacity.

Questions about this item

Does this DDR4-2666 ECC UDIMM fit a standard 288-pin DIMM slot?

Yes, it uses the standard DDR4 UDIMM form factor with 288 pins, matching the slot used by compatible Synology systems.

What is the correct way to seat the module so the ECC function initialises?

Align the notch with the slot key, press firmly until both side latches click shut, then power on and verify ECC status in the DSM memory health page.

When should this 8 GB DDR4-2666 ECC UDIMM be replaced?

Replace it if DSM reports correctable ECC errors that increase over time, or if the system fails memory diagnostics during boot.
