SKU CH-K4HK-PWZ2E

16 GB DDR4 ECC registered DIMM running at 2666 MT/s for server workloads

  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity for dense server configurations
  • DDR4-2666 speed delivers 2666 MT/s bandwidth for responsive performance
  • 16 GB capacity supports larger virtual-machine densities per host
  • CAS latency 19 optimises timing for consistent throughput

Axiom 16GB DDR4-2666 ECC RDIMM

This Axiom module is a 16GB DDR4-2666 ECC registered DIMM designed for server platforms that require error-correcting memory. It suits administrators upgrading or populating compatible enterprise systems.

Verify DDR4 RDIMM slot support

Confirm your motherboard accepts DDR4 registered ECC DIMMs and operates at 2666 MT/s before ordering. Mixing registered and unbuffered modules is not supported on most platforms.

Standard JEDEC voltage and thermals

The module runs at standard DDR4 voltage with passive cooling under normal server workloads. It produces no audible noise and draws power within the DDR4 specification for registered DIMMs.

Questions about this item

Does the AX42666R19C/16G include any cables or brackets, or is it just the memory module?

The AX42666R19C/16G is supplied as a single DDR4-2666 ECC RDIMM module; no cables, brackets or additional accessories are included.

What do the numbers 16, 2666 and 19 in the model name tell me about capacity, speed and latency?

The module provides 16 GB capacity, operates at 2666 MT/s and has a CAS latency of 19 cycles.

Will I see the full 2666 MT/s speed once this RDIMM is installed in a compatible server?

The module runs at its rated 2666 MT/s when the server platform supports DDR4-2666; otherwise it will downclock to the highest speed the platform allows.
