2-power 2P-KN.4GB07.044 - 4 GB - 1 x 4 GB - DDR4 - 2666 MHz

For laptops and small-form-factor systems that demand reliable performance without the premium price tag, the 2-POWER 2P-KN.4GB07.044 delivers a single 4GB DDR4 SODIMM running at 2666 MHz. Unlike generic modules that often arrive with mismatched timings or questionable compatibility, this stick follows the JEDEC CL19 standard, ensuring it drops into a wide range of notebooks and mini PCs with no fuss. It is the practical upgrade for breathing new life into an ageing machine or adding a second module for dual-channel benefits.

Highlights

• 4GB capacity in a single module, ideal for basic multitasking and everyday computing.
• DDR4 technology with a 2666 MHz clock speed for snappy responsiveness.
• 260-pin SODIMM form factor fits most laptops, all-in-ones, and compact desktops.
• Non-ECC, unbuffered design matches consumer and business notebooks.
• Low 1.2V operating voltage reduces power draw and heat output.
• Single-rank (1Rx8) configuration ensures broad compatibility.
• No heat spreader, so it fits even in ultra-thin chassis with tight clearance.

In daily use

Pop this module into an empty SODIMM slot and the system immediately sees a full 4GB of DDR4-2666 memory. The CL19 latency keeps latency predictable, while the 1.2V supply sips power compared to older DDR3L modules. Whether you are restoring an older ultrabook, upgrading a mini PC used as a home server, or simply replacing a failed stick, the 2P-KN.4GB07.044 works silently in the background. Because it is unbuffered and non-ECC, it is perfectly matched to the memory controllers found in Intel and AMD mobile platforms from the last several generations.
