2-power 2P-VH638AAR - 4 GB - 1 x 4 GB - DDR3 - 1333 MHz

Upgrading an older laptop can breathe new life into daily tasks, and the 2-POWER 2P-VH638AAR memory module delivers exactly that. A technician slots this single 4GB DDR3 SODIMM into a notebook's empty memory bay, and the system immediately gains smoother multitasking for office documents, web browsing, and light photo editing. Built for portable computers, the module runs at 1333 MHz with a PC3-10600S rating, matching the needs of many Intel and AMD platforms from the DDR3 era.

Key specifications

• Capacity: 4 GB (1 x 4 GB)
• Memory type: DDR3 SODIMM
• Speed: 1333 MHz (PC3-10600S)
• Form factor: 204-pin SODIMM
• CAS latency: CL9
• Voltage: 1.5 V
• Error correction: Non-ECC, unbuffered
• Application: Laptop / Notebook

Why choose it

This module comes from 2-POWER, a brand known for reliable replacement parts and upgrades. It uses standard 1.5V DDR3 technology, ensuring compatibility with a wide range of notebooks that require low-profile SODIMM modules. The 4GB capacity is a practical step up for systems still running 2GB or 3GB, reducing slowdowns when multiple browser tabs or office applications are open. Installation is straightforward: the 204-pin connector clicks into place, and the module is automatically detected by the system BIOS.

Ideal use cases

• Refreshing aging laptops for everyday productivity
• Upgrading a single SODIMM slot from 2GB to 4GB
• Replacing a failed memory module in a notebook
• Building or repairing small-form-factor systems that use SODIMM

Good to know

Before ordering, verify that your laptop supports DDR3 SODIMM modules at 1333 MHz and has an available memory slot. The module is unbuffered and non-ECC, which is standard for consumer notebooks. It operates at 1.5V, so it is not compatible with DDR3L-only systems that require 1.35V. For best results, pair with an identical module if running dual-channel, though it will function perfectly as a single stick. The module is backed by 2-POWER's quality assurance for dependable performance.
