## Summary description

The OWC OWC1600DDR3S4GB is a 4GB DDR3 memory module designed for laptops. With a clock speed of 1600 MHz and a CAS latency of 11, this 204-pin SO-DIMM module ensures efficient performance and reliability. Upgrade your laptop's internal memory for improved multitasking and faster application loading times.

## Long description

The OWC DDR3 4GB 1600MHz memory module is a 204-pin SO-DIMM designed for laptop installations and compatible notebook upgrades. This 4 GB DDR3 module operates at 1600 MHz with CL11 timing and a low operating voltage of 1.35 V, providing a balance of capacity and efficiency for systems that accept DDR3L SO-DIMM memory. It is commonly used as an internal memory upgrade to improve multitasking and reduce application load times in older laptop models, including 2012 MacBook Pro (non-Retina) systems that require PC3-12800 DDR3L modules.
Advantages
This module delivers a straightforward capacity increase to 4 GB, enabling smoother switching between applications and better memory handling for typical office, web browsing and media tasks. The 1600 MHz clock speed and CL11 latency provide reliable responsiveness for legacy DDR3 platforms, while the 1.35 V operating voltage supports lower power draw compared with older 1.5 V modules. The SO-DIMM 204-pin form factor ensures physical compatibility with laptops and small form-factor systems that use DDR3L memory.
Suitable for (tasks / use cases)
 Upgrading laptop memory to improve multitasking and general responsiveness
 Replacing a faulty or failed SO-DIMM module in compatible notebooks
 Increasing usable memory for light photo editing, office applications and web browsing
 Restoring performance in older laptop models such as 2012 non-Retina MacBook Pro
Key specifications
 Capacity: 4 GB of internal memory
 Memory type: DDR3 (low-voltage DDR3L compatible)
 Clock speed: 1600 MHz
 CAS latency: CL11
 Form factor: 204-pin SO-DIMM
 Operating voltage: 1.35 V
How to use
Power off the laptop and disconnect any power sources. Access the memory bay according to the laptop manufacturer’s instructions, typically by removing the bottom cover or a dedicated access panel. Ground yourself to avoid electrostatic discharge, then remove the existing SO-DIMM if present by spreading the retention clips and gently sliding the module out. Align the notch on the new 204-pin module with the slot and insert at an angle until the contacts seat, then press down until the retention clips lock it in place. Reassemble the laptop, reconnect power, and verify the system recognizes the new 4 GB module in the firmware or operating system memory information.
Usage recommendations
If the laptop supports dual-channel memory, install identical modules in matched slots for optimal bandwidth. Check the system documentation for maximum supported memory and whether low-voltage (1.35 V) DDR3L modules are required. When combining with existing modules, ensure compatible clock speed and latency to avoid instability.
