Axiom 838081-B21-AX 16 GB DDR4 2666 MHz CL19 1.2 V Registered ECC 288-pin DIMM

SKU CH-1SWW-DYS5X

16 GB DDR4 registered ECC DIMM at 2666 MHz with CL19 timing and 1.2 V operation

  • 16 GB DDR4 memory expands server capacity
  • 2666 MHz speed supports demanding workloads
  • CL19 latency ensures responsive data access
  • ECC registered design protects data integrity

16 GB DDR4 2666 MHz Registered ECC DIMM

This Axiom memory module provides 16 GB of DDR4 capacity at 2666 MHz with CL19 latency. It operates at 1.2 V and uses a 288-pin registered DIMM form factor with ECC support. The single-rank x4 configuration is designed for compatible server and workstation platforms.

Suits servers needing registered ECC memory

Buyers who require unbuffered non-ECC DIMMs for consumer motherboards should look elsewhere. Systems that do not support registered modules or DDR4-2666 operation cannot use this kit. Those needing higher capacities per module or different latency timings must select alternative memory.

Highlights

  • 16 GB DDR4 memory expands server capacity
  • 2666 MHz speed supports demanding workloads
  • CL19 latency ensures responsive data access
  • ECC registered design protects data integrity

Questions about this item

Does this 288-pin DDR4 DIMM require a motherboard that supports registered ECC memory?

Yes, the module is registered and ECC, so the platform must explicitly support registered ECC DDR4 for it to function.

Can the 16 GB single-rank stick populate a slot in a server that already has dual-rank DDR4-2666 modules installed?

Mixing single-rank and dual-rank DDR4-2666 modules is generally possible if the server's memory controller and BIOS allow mixed-rank configurations.
