Model: OWC1S6T31R804GB-B936-SF
Introduction
This manual provides essential information for the installation, operation, and maintenance of your OWC 4GB DDR3L 1600MHz SODIMM Memory Module. This module is designed to enhance the performance of compatible systems by increasing available RAM. Please read these instructions carefully before proceeding with installation.
Setup and Installation
Installing a memory module requires careful handling. Always ensure your system is powered off and disconnected from its power source before opening it. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge (ESD), which can damage electronic components.
- Preparation: Power down your computer completely and unplug all cables. If it's a laptop, remove the battery.
- Access Memory Slots: Open your computer case or laptop's memory compartment. Refer to your computer's specific service manual for instructions on how to access the memory slots.
- Locate Slots: Identify the available SODIMM slots. If you are replacing existing modules, gently push the retention clips outward to release the old module, then carefully remove it.
- Insert New Module: Hold the OWC memory module by its edges, aligning the notch on the module with the key in the memory slot. Insert the module firmly at a 45-degree angle.
- Secure Module: Push the module down until the retention clips on both sides snap into place, securing the module horizontally.
- Close System: Close the memory compartment or computer case. Reconnect all cables and the battery (if applicable).
- Power On: Power on your computer. The system should automatically detect the new memory. You can verify the installed RAM in your operating system's system information.

Operating the Memory Module
The OWC 4GB DDR3L 1600MHz SODIMM memory module operates automatically once installed and recognized by your system. Its primary function is to provide fast, temporary storage for data that the CPU actively uses, thereby improving overall system responsiveness and multitasking capabilities. No direct user interaction is required for its operation.
Maintenance
Memory modules generally require minimal maintenance. To ensure optimal performance and longevity:
- Keep Clean: Ensure the computer's interior is free from dust and debris, which can impede airflow and lead to overheating.
- Handle Carefully: When handling the module, always hold it by the edges to avoid touching the gold contacts or integrated circuits.
- Environmental Conditions: Operate your computer within recommended temperature and humidity ranges to prevent component stress.
Troubleshooting
If you encounter issues after installing your OWC memory module, consider the following troubleshooting steps:
- No Display/System Not Booting: This often indicates that the memory module is not seated correctly. Power off the system, unplug it, and re-seat the module firmly in its slot. Ensure the retention clips are fully engaged.
- Incorrect RAM Amount Detected: Verify that the module is fully seated. If the issue persists, check your system's BIOS/UEFI settings to confirm the detected memory. Ensure your system's motherboard supports the installed memory type and speed.
- System Instability/Crashes: This could be due to incompatible memory or a faulty module. If you have multiple modules, try testing them one by one. Ensure the module is compatible with your system's specifications.
- Compatibility Check: Double-check that your computer model and motherboard support DDR3L SODIMM memory at 1600MHz and the specified voltage (1.35V).
If these steps do not resolve the issue, please contact OWC Technical Support for further assistance.
