A-Tech 8GB DDR4 2666MHz ECC RDIMM 1Rx4 Server Memory

SKU CH-2329-KKG51

8 GB DDR4 2666 MHz ECC registered DIMM with CL19 latency and 1.2 V operation for server workloads

  • Capacity8GB
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 8GB capacity expands server multitasking headroom
  • DDR4 2666MHz PC4-21300 speed accelerates data throughput
  • ECC RDIMM registered design protects data integrity
  • 1Rx4 single-rank layout optimises memory-channel efficiency
  • 20V standard voltage reduces platform power draw

Server Memory Upgrade

This A-Tech module adds 8 GB of DDR4 2666 MHz registered ECC memory to compatible servers and workstations. It uses a single 288-pin DIMM operating at the standard 1.2 V. The registered design helps maintain signal integrity in multi-DIMM configurations.

Sustained Workload Behaviour

The CL19 latency and 1Rx4 organisation deliver consistent throughput for long-running server tasks such as virtualisation hosting or database caching. ECC error correction protects data integrity during continuous operation without the variability seen in unbuffered consumer modules.

Compatibility Deciding Factor

This part is a registered ECC RDIMM and will not function in platforms that require unbuffered non-ECC UDIMMs. Verify that your motherboard and processor explicitly support registered ECC DDR4 before ordering.

Questions about this item

How much power does the 1.20V DDR4 2666 module draw when running continuously?

It operates at the standard DDR4 voltage of 1.20V, keeping power draw and heat low during sustained server workloads.

What motherboard slot is required for this 288-pin RDIMM?

A DDR4 RDIMM slot supporting ECC registered memory; the module will not work in desktop UDIMM slots.

Can I add this CL19 1Rx4 stick alongside existing DDR4 2666 ECC RDIMMs?

Yes, if your platform supports mixed ranks and the same voltage, it will run at the common 2666MHz speed.
