  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Product colorGreen
  • 8 GB capacity fits everyday workloads with a single module
  • 2666 MHz DDR4 speed delivers responsive data throughput
  • CL19 latency keeps timing tight for stable operation
  • 2 V JEDEC voltage reduces power draw and heat
  • 288-pin DIMM form factor installs directly in standard desktop slots

Capacity and role

This ADATA Premier module delivers 8 GB of DDR4 desktop memory in a single 288-pin DIMM. It targets mainstream PC and server builds that need a straightforward capacity increase without overclocking headroom. The green PCB and standard height suit typical chassis layouts.

Upgrade path

The stick replaces an empty slot or a lower-capacity DDR4 module running at 2666 MHz with CL19 timings. The jump is worth it when the platform already supports DDR4 2666 and the workload benefits from the extra 8 GB rather than tighter latencies or higher frequencies.

Installation notes

Installation follows the usual DIMM alignment: open the latches, match the notch, press until the clips click. The 1.2 V JEDEC voltage means no manual BIOS tuning is required. The main risk is mixing this CL19 module with faster or lower-latency kits, which forces the system to run at the slowest common settings.

Questions about this item

Will the 3.12 cm module height clear my CPU cooler?

The module is 3.12 cm tall, which matches standard JEDEC DIMM height, so it fits under most tower coolers without interference.

Which slot do I use first on a four-slot motherboard?

Install the single 288-pin DIMM in the slot your motherboard manual labels as the primary channel, usually slot 2 or 4, to avoid single-channel operation.

Does the green PCB need cleaning or thermal pads later?

No maintenance is required; the unbuffered DDR4 module runs at 1.2 V within 0–85 °C and has no moving parts or user-serviceable components.
