4GB DDR3L SODIMM for laptops

This 4GB OWC module uses DDR3L technology at 1600 MHz with CL11 latency and runs at 1.35 V. It fits 204-pin SO-DIMM slots in laptops, all-in-one PCs and compatible NAS units. The unbuffered, non-ECC design follows JEDEC standards for a straightforward capacity increase.

Installation experience

Insert the module at an angle into the SO-DIMM slot until the retaining clips click shut. Most systems recognise the new memory automatically on the next boot. If the machine fails to start, reseat the stick and verify the slot is free of dust; mismatched voltage or an incorrect DDR generation are the usual causes of a no-post condition.

Compatibility checklist

Confirm the host device accepts DDR3L 1.35 V SO-DIMMs and has a free 204-pin slot. Check the manufacturer’s qualified-vendor list or memory configurator for the exact part number 1S6T32R804GB. Ensure the system does not require registered or ECC modules, as this stick is unbuffered and non-ECC.

Questions about this item

How can I confirm the 4GB DDR3L 1600 SODIMM is running at 1.35V and CL11 after installation?

Enter the system BIOS or use a tool like CPU-Z to verify the detected voltage reads 1.35V and the CAS latency shows CL11 for the installed module.

Does the 204-pin DDR3L 1600 module ship alone, or are tools or extra parts included in the box?

The package contains only the single 4GB SODIMM; no screwdriver, thermal pad, or additional components are supplied.

Which OWC DDR3L 1600 capacity should I pick if my laptop has two slots and supports up to 8GB total?

Choose the 4GB module and install two of them to reach the 8GB maximum across both slots.
