An 8 GB DDR4 desktop module running at 2666 MHz with CL19 latency and 1.2 V operation

  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • Rated voltage1.2 V
  • Product colorBlack PCB
  • 8GB capacity supports smoother multitasking on DDR4 desktops
  • 2666MHz speed with CL19 latency delivers responsive performance
  • 2V operation reduces power draw versus DDR3 modules
  • 288-pin UDIMM form factor fits standard desktop DIMM slots
  • Non-ECC unbuffered design suits consumer PC and workstation builds

8GB DDR4 2666MHz UDIMM for desktop upgrades

This single 8 GB module runs at 2666 MHz with CL19 latency and 1.20 V operation. It fits standard 288-pin DDR4 UDIMM slots on compatible desktops and workstations. The non-ECC unbuffered design suits mainstream consumer platforms.

Thermals noise and power draw

Operating at 1.20 V keeps power consumption low compared with older DDR3 modules. The low voltage also reduces heat output, helping system fans run quieter during typical workloads. No active cooling is required for normal operation.

2666MHz CL19 speed rating

The module is rated for 2666 MHz at CL19, matching the PC4-21300 specification. Systems that support 2666 MHz will run at that speed; boards limited to 2133 MHz or 2400 MHz will downclock automatically. It is not compatible with laptop SODIMM slots.

Questions about this item

How do I install the 288-pin UDIMM and what step do people often miss?

Align the notch with the slot key, press firmly until the retention clips click, and verify the motherboard recognises the full 8GB at 2666MHz in BIOS.

What maintenance or replacement will the 1.2V DDR4 module need later?

No scheduled maintenance is required; replace only if memory errors appear or a capacity upgrade is desired.

What limit appears first under sustained load with CL19 timing?

The CAS latency of 19 cycles at 2666MHz sets the response-time floor during continuous memory-intensive work.
