## Long description

The ADATA DDR4 16 GB 2666 MHz memory module is a single 16 GB DIMM designed for use in desktop PCs and compatible servers. Operating at 2666 MHz with DDR4 architecture and a 288-pin form factor, the module delivers increased available RAM for applications and multitasking while maintaining standard DDR4 power requirements. With a CAS latency of 19 and 1.2 V operating voltage, this module provides predictable performance for everyday computing, office work, content creation and light server tasks.
Advantages
This 16 GB DDR4 module increases system memory capacity to improve multitasking and reduce paging. The 2666 MHz clock speed offers a balance between bandwidth and compatibility across a wide range of motherboards. Low 1.2 V operating voltage helps lower power consumption compared with older memory generations. The 288-pin DIMM form factor ensures straightforward installation in standard desktop memory slots.
Suitable for
 Upgrading desktop PC memory for smoother multitasking
 Office productivity software and web browsing with many open tabs
 Content editing and light photo/video work where additional RAM is beneficial
 Small-scale server or workstation tasks requiring increased memory capacity
Key specifications
 Capacity: 16 GB
 Memory type: DDR4
 Clock speed: 2666 MHz
 Form factor: 288-pin DIMM
 CAS latency: 19
 Operating voltage: 1.2 V
How to use
Power down the computer and disconnect it from mains power before installing the memory module. Open the PC case to access the motherboard DIMM slots, consult the motherboard manual for recommended slot population and compatibility. Align the notch on the 288-pin DIMM with the slot key and press evenly until the retaining clips engage. After installation, reconnect power and boot the system; verify the new memory is recognized in BIOS/UEFI or the operating system memory information.
Usage recommendations
Install memory modules in matching pairs when the motherboard supports dual-channel operation to achieve the best memory bandwidth. Check motherboard documentation for maximum supported capacity per slot and supported memory frequencies. When mixing modules, use modules with similar specifications (type, speed, voltage, and CAS latency) to avoid compatibility issues.
