Kingston Technology Corp. KCS-UC426/16G 16 GB DDR4-2666 server RAM

SKU CH-66N6-4VA1Z MPN KCS-UC426/16G

16 GB DDR4-2666 registered ECC DIMM with CL19 latency for compatible Cisco UCS B-Series and C-Series servers

  • ECC protection prevents data corruption in critical server workloads
  • Registered signal processing improves stability for high-density memory configurations
  • 2666 MHz DDR4 speed delivers responsive performance for virtualisation and databases
  • 16 GB single module allows flexible capacity scaling across 288-pin DIMM slots
  • Validated for Cisco UCS B-Series and C-Series servers including M5 blade and rack models

16 GB DDR4-2666 Registered ECC Module

This 16 GB DDR4-2666 registered ECC DIMM is built for Cisco UCS B-Series and C-Series servers including the B200 M5, B480 M5, C220 M5, C240 M5 and C480 M5. It targets administrators who need validated, single-module capacity upgrades for those specific platforms.

Thermals, Noise and Power Draw

As a passive memory module it produces no audible noise and adds negligible heat to the chassis airflow. Power consumption follows the standard DDR4-2666 registered ECC profile for 1.2 V operation.

288-Pin DDR4-2666 Registered ECC Interface

The module uses a 288-pin DIMM form factor with DDR4-2666/PC4-21300 signalling, CL19 latency, registered signal processing and on-die ECC. Compatibility is limited to the listed Cisco UCS servers; other platforms are not validated.

Questions sur cet article

How do I install the KCS-UC426/16G into a Cisco UCS B200 M5 blade server, and what step is commonly missed?

Power down the blade, open the chassis, align the 288-pin DIMM notch with the slot key, press firmly until both retention clips click, then verify the registered ECC module is recognised in BIOS before closing the chassis.

What maintenance or replacement will this 16 GB DDR4-2666 registered ECC module need over its service life?

No scheduled maintenance is required; the module carries a lifetime warranty, so replacement only occurs if a memory error is logged or a capacity upgrade is planned.

What limit appears first when the KCS-UC426/16G runs sustained workloads at CL19 2666 MHz?

The CAS latency of CL19 and the DDR4-2666 data rate set the bandwidth ceiling; sustained throughput cannot exceed the PC4-21300 rating regardless of load duration.
