4GB G.Skill SO-DIMM 1600 (2x 2 GB) kit dual (F3-12800CL9D-4GBSQ, SQ, Lite Retail)

The G.Skill DDR3 4GB 1600MHz 2x2GB kit (F3-12800CL9D-4GBSQ) is a dual-channel laptop memory solution consisting of two 2GB SO‑DIMM modules for a total of 4GB. Operating at 1600 MHz (PC3-12800) with CAS latency 9 and 1.5 V, this 204-pin DDR3 kit is intended to improve multitasking and general system responsiveness in compatible notebooks and small form-factor systems.

Advantages

This G.Skill memory kit provides a balanced combination of frequency and latency for DDR3 systems, delivering stable performance at 1600 MHz and CL9. The dual-module configuration enables dual-channel operation when installed in supported notebooks or motherboards. The 1.5 V operating voltage matches standard DDR3 specifications, ensuring wide compatibility with devices that accept 204-pin SO‑DIMM modules.

Suitable for

• Upgrading laptop memory to 4GB total capacity
• Replacing faulty or missing SO‑DIMM modules in notebooks
• Small form-factor PCs and embedded systems that accept 204-pin DDR3 SO‑DIMM

How to use

Power off the laptop and remove the battery if possible. Open the memory compartment following the manufacturer’s instructions, then ground yourself to avoid electrostatic discharge. Insert the two 204-pin SO‑DIMM modules into the memory slots at a slight angle until the retention clips click into place. Reassemble the device, reinstall the battery if removed, and power on. Verify in the system BIOS or operating system that the total 4GB of RAM is recognized and that dual‑channel mode is enabled if supported.

Recommendations

Install this DDR3-1600 2x2GB kit in systems explicitly supporting 204-pin SO‑DIMM DDR3 modules and 1.5 V operation. For optimal compatibility, pair with identical or manufacturer‑recommended modules and ensure the notebook BIOS is up to date.
