Kit composition

This G.SKILL kit provides 4GB of DDR3 laptop memory arranged as two 2GB modules. It suits users upgrading older notebooks that accept 204-pin SO-DIMMs and want a matched pair for dual-channel operation. Buyers needing more than 4GB total capacity or a newer DDR generation should look elsewhere.

Compatibility checks

Verify that your laptop uses DDR3 SO-DIMM slots and supports 1600MHz modules at 1.50V. The kit runs at CL9 9-9-9-28 timings and is unbuffered non-ECC; systems requiring registered or ECC memory will not work with these sticks. Confirm the board has two free slots to gain the dual-channel benefit.

Build and daily use

Modules ship without heat spreaders, keeping the profile low for tight chassis clearances. Standard 204-pin gold-edge connectors seat firmly in SO-DIMM sockets and withstand repeated swaps during service. The dual-channel kit simplifies installation because both sticks are validated to run together at the rated speed and voltage.

Questions about this item

Does the kit include two 204-pin SO-DIMM modules or do I need to buy them separately?

The kit contains two 2 GB DDR3 SO-DIMM modules, giving 4 GB total in a dual-channel configuration; nothing else is required for installation.

Should I choose the CL9 1600 MHz kit or a different speed grade for my laptop?

This model runs at DDR3 1600 with CL9 9-9-9-28 timing at 1.50 V; select it when your laptop supports that exact speed and voltage.

What does the PC3 12800 rating mean for actual bandwidth in my machine?

PC3 12800 indicates up to 12.8 GB/s peak bandwidth per channel, which the dual-channel kit can utilise when the memory controller operates at 1600 MHz.
