2-power 2P-KN.4GB07.007 - 4 GB - 1 x 4 GB - DDR3L - 1600 MHz

4 GB DDR3L at 1600 MHz — that's the sweet spot for giving an older laptop a second wind. The 2-power 2P-KN.4GB07.007 is a single 4 GB SO-DIMM stick, built for notebooks that need more memory without draining the battery.

Why this memory works

It runs at just 1.35 V, which means less heat and longer battery life compared to standard DDR3. For everyday tasks — office documents, a dozen browser tabs, light photo editing — this module keeps things snappy. It's non-ECC and unbuffered, so it slots straight into most DDR3L laptops.

Who it's for

• Anyone upgrading an old laptop that's struggling with 2 GB or 4 GB of RAM
• Replacing a dead or faulty memory module in a notebook
• Building a low-power, energy-efficient portable system

Key specs at a glance

• Capacity: 4 GB (1 x 4 GB)
• Type: DDR3L SO-DIMM (204-pin)
• Speed: 1600 MHz (PC3-12800)
• Voltage: 1.35 V
• CAS latency: CL11
• Rank: Single rank (1Rx8)
• No heat spreader — slim design fits tight slots

How to use

Check your laptop's manual or CPU-Z to confirm it supports DDR3L and has a free SO-DIMM slot. Power off, remove the battery (if possible), and ground yourself. Insert the module at a 30-degree angle, press down until it clicks, and you're set.

Tip: If your laptop has two slots, adding this 4 GB stick to an existing 2 GB or 4 GB module can give you dual-channel performance — just make sure they're the same speed and voltage.
