Axiom SmartMemory 16GB DDR4 2666MHz CL19 ECC Registered DIMM 815098B21AX

SKU CH-2R0X-A4AP5

A 16 GB DDR4 ECC registered DIMM running at 2666 MHz with CL19 latency for server workloads

  • BIOS/Performance ProfileIntel XMP 2.0
  • ECC protects data integrity on servers
  • Registered signal processing improves stability under load
  • 2666 MHz speed with CL19 latency
  • 20 V operation reduces power draw
  • 288-pin DIMM fits standard server slots

Server-Grade 16GB DDR4 Registered DIMM

This Axiom SmartMemory module delivers 16GB of DDR4 memory at 2666MHz with ECC error checking and registered signal processing. It operates at a standard 1.20V and uses a 288-pin DIMM form factor designed for server environments. The single-module configuration simplifies capacity upgrades.

Suited for servers needing ECC reliability.

The registered design and ECC support make this module appropriate for server platforms that require data integrity and signal buffering. Systems without registered memory support cannot use this DIMM. Builders needing non-ECC unbuffered memory for consumer motherboards should look elsewhere.

CL19 CAS latency at 2666MHz determines

The module runs at CL19 latency timings under the DDR4-2666/PC4-21300 standard. This timing figure directly affects memory access speed in latency-sensitive workloads. Verify that your server platform supports this speed and latency combination before installation.

Questions about this item

Should I pick the 16 GB module or add another capacity?

This part is sold as a single 16 GB DIMM; choose it when you need exactly 16 GB or plan to populate matching slots with identical modules.

What does the 2666 MHz rating deliver in a server?

The module runs at 2666 MHz with CL19 timing at 1.20 V, providing DDR4-2666 bandwidth for registered ECC workloads.

How does the 288-pin DDR4 interface limit performance?

The 288-pin DDR4 connection operates at the DDR4-2666 standard, so throughput is bounded by that specification.
