DDR4 2666 ECC RDIMM Kit

This 16GB kit contains two 8GB DDR4 2666 MHz ECC Registered DIMMs built for servers and workstations. Each module uses a single-rank x4 layout with CL19 latency and runs at the standard 1.20V DDR4 voltage. The registered design adds a buffer that helps maintain signal integrity on heavily populated memory channels. It is not compatible with desktop or laptop computers.

Platform Compatibility Check

Verify that your server or workstation motherboard supports DDR4 Registered ECC memory in a 288-pin DIMM form factor before ordering. The system must accept ECC RDIMM modules and be able to run at 2666 MHz with CL19 timing at 1.20V. Consult the vendor manual for approved memory configurations, maximum capacity per slot, and correct channel population rules.

Dual-Channel Kit Benefit

The matched pair enables dual-channel operation on platforms that support it, doubling the memory bus width compared with a single module. This increases available bandwidth for memory-intensive workloads such as virtualization, database caching, and large dataset processing. Both modules are tested together to ensure consistent timing and reliable operation across both channels.

Highlights

  • DDR4 2666 MHz rated speed accelerates data throughput
  • ECC registered design detects and corrects single-bit errors
  • Single-rank 1Rx4 organisation optimises signal integrity
  • 20 V standard voltage reduces power draw per module

Questions about this item

What comes in the box and do I need anything else to install this kit?

The kit includes two 8 GB DDR4 2666 MHz ECC RDIMM modules. No extra parts are required; install both modules into compatible registered DIMM slots on a supported server or workstation motherboard.

Should I choose the 16 GB dual-channel kit or a different capacity for my server?

This 16 GB kit provides two matched 8 GB single-rank x4 modules for dual-channel operation. Select it when your platform supports registered ECC DDR4 and you need 16 GB in a balanced two-module configuration.

What does the 2666 MHz rating mean once the memory is running in my system?

The modules operate at DDR4 2666 MHz (PC4-21300) with CL19 latency at 1.2 V, delivering the rated bandwidth and error-correction when the platform enables the supported memory speed.
