2-power 2P-PA5104U-1M4G - 4 GB - 1 x 4 GB - DDR3L - 1600 MHz

For laptops and small form factor systems that demand reliable low-voltage memory, the 2-POWER 2P-PA5104U-1M4G delivers a single 4GB DDR3L SODIMM running at 1600MHz. Unlike standard DDR3 modules that operate at 1.5V, this module runs at just 1.35V, reducing power consumption and heat generation—an essential advantage for battery-powered devices and compact enclosures where thermal headroom is limited. The 204-pin unbuffered design ensures broad compatibility with a wide range of notebooks and mini PCs, while the non-ECC configuration keeps latency low and cost effective for everyday computing tasks.

Highlights

• 4GB capacity in a single module for easy upgrade or replacement
• DDR3L technology with 1.35V operation for improved energy efficiency
• 1600MHz speed (PC3L-12800) for responsive multitasking
• 204-pin SODIMM form factor fits standard laptop memory slots
• Unbuffered, non-ECC design for compatibility with consumer and business laptops

In daily use

Installing this module brings an immediate improvement to systems that are running with insufficient memory. Applications launch faster, browser tabs remain active without excessive swapping, and the lower voltage helps extend battery runtime during mobile use. The module is also an excellent choice for upgrading older laptops that originally shipped with 2GB or 4GB of DDR3L memory, allowing them to handle modern operating systems and office suites more comfortably. Because it is a single 4GB stick, users can often pair it with an existing identical module to reach 8GB in dual-channel mode, depending on the system's configuration.
