ADATA | Premier DDR4 RAM | 8 GB | SO-DIMM | 2666 MHz | Notebook | Registered No | ECC No

The ADATA 8 GB DDR4 2666 MHz SO-DIMM (model AD4S26668G19-SGN) is a laptop memory module designed to upgrade compatible notebooks. With an 8 GB capacity, 2666 MHz clock speed and CAS latency 19, this DDR4 module provides faster data transfer and lower power draw than previous DDR3 modules, operating at 1.2 V and following JEDEC standards for reliability and compatibility.

Advantages

ADATA DDR4 2666 SO-DIMM modules offer higher transfer rates and improved energy efficiency compared with DDR3, enabling smoother multitasking and reduced heat generation. The 1.2 V operating voltage lowers power consumption by approximately 20% versus DDR3, which can help extend battery life in notebooks. Modules comply with JEDEC and RoHS standards and are optimized for modern Intel platforms including Skylake and Coffee Lake, with forward compatibility for Kaby Lake and Cannon Lake.

Suitable for

• Upgrading notebook memory to 8 GB DDR4 for everyday productivity
• Improving multitasking performance and responsiveness
• Replacing or adding a 260-pin SO-DIMM module in compatible laptops

How to use

Power off the notebook and remove the battery if applicable. Open the memory compartment or access panel according to the laptop manufacturer’s instructions. Ground yourself to avoid electrostatic discharge, then align the 260-pin SO-DIMM module with the slot notch and insert at a slight angle. Press the module down until the side clips lock into place. Reassemble the laptop, reconnect power, and verify the new memory is recognized in the system BIOS or operating system.

Recommendations

Install this ADATA 8 GB DDR4 2666 MHz SO-DIMM in notebooks that support DDR4 2666 or compatible JEDEC frequencies and 260-pin SO-DIMM modules. For dual-channel operation and optimal performance, pair with a matching module (same capacity, speed and voltage) where the laptop supports dual-channel memory.
