2-power 2P-A7398800 - 4 GB - 1 x 4 GB - DDR3 - 1600 MHz

When a laptop starts to feel sluggish, the culprit is often insufficient memory. The 2-POWER 2P-A7398800 module steps in with a straightforward upgrade: 4 GB of DDR3 running at 1600 MHz in a compact 204-pin SO-DIMM form factor. This isn't a generic stick—it's built to match the electrical and physical requirements of specific notebook platforms, so you get a drop-in fit without guesswork. Single-rank construction and CL11 latency keep power draw low and signal integrity high, which matters in tight chassis with limited airflow.

Highlights

• 4 GB capacity, ideal for breathing new life into older laptops
• DDR3-1600 (PC3-12800) with CL11 timings for reliable everyday performance
• 204-pin SO-DIMM, non-ECC, unbuffered—matches standard notebook slots
• 1.5 V operating voltage, compliant with JEDEC DDR3 specifications
• Single-rank (1Rx8) configuration for broad compatibility

In daily use

Pop this module into a compatible ultrabook or business notebook and the difference is immediate: applications launch faster, browser tabs stay responsive, and multitasking between office tools, video calls, and media playback feels smoother. Because it's a single 4 GB stick, you can pair it with an existing identical module for dual-channel operation or use it alone to replace a failed part. The low 1.5 V draw helps preserve battery life, while the standard SO-DIMM outline ensures it fits under most access panels without clearance issues.
