Speed DDR4 2666 (PC4 21300)

  • Dual-channel kit doubles bandwidth with two 8 GB modules
  • 2666 MHz DDR4 speed rated at PC4-21300 for faster data rates
  • CL19 CAS latency keeps timing tight at standard voltage
  • 2 V DDR4 power draw reduces heat and energy use
  • 288-pin UDIMM form factor fits standard desktop memory slots

Kit contents and target system

This 16GB kit contains two 8GB DDR4 UDIMM modules rated at 2666MHz with CL19 latency. It is built for desktop PCs that accept 288-pin DIMMs and run at the standard 1.2V DDR4 voltage. The dual-channel layout suits mainstream workstations and home computers needing a straightforward capacity increase.

Suitability check

The kit fits non-ECC, unbuffered DDR4 slots on AMD and Intel platforms. Systems that require registered or ECC memory cannot use these modules. Builders who need higher frequencies, lower latencies or larger single-module densities should consider other options.

Deciding specification

The tested speed is 2666MHz (PC4-21300) at 1.20V with CL19 timing. If the motherboard or CPU officially supports DDR4-2666, the memory will run at its rated frequency; otherwise it will downclock to the highest speed the platform allows.

Questions about this item

Will this kit fit my motherboard's memory slots?

The kit uses standard 288-pin DDR4 DIMM modules, which fit any desktop board with DDR4 slots.

Can I run these modules at their rated speed without changing BIOS settings?

They operate at 1.2 V and 2666 MHz, the standard DDR4 speed and voltage most boards enable automatically.

Does the dual-channel kit require matched slots for best performance?

Yes, install one 8 GB module in each channel pair — usually slots of the same colour — to activate dual-channel mode.
