Frequently Asked Questions

Will the G.SKILL Ripjaws 16GB DDR4 SO-DIMM fit my laptop?

It is a 260-pin DDR4 SO-DIMM for laptops and notebooks. It will not fit DDR3, DDR5 or desktop DIMM slots. To confirm that your model is validated, check G.SKILL's memory QVL or RAM Configurator tool on the G.SKILL website.

What speed and timings does the F4-2400C16S-16GRS run at?

It is rated for DDR4-2400 at CL16-16-16-39 and 1.20V. With default BIOS settings on compatible hardware, it boots at the JEDEC default SPD speed.

Can I mix this module with the RAM already in my laptop?

G.SKILL advises against mixing memory kits because they are sold as matched sets and mixing can cause instability or system failure. For two modules, use a matched pair.

Is this a single stick or a two-module kit?

It is one 16GB module (1x16GB). In a two-slot laptop, the second slot stays free. A single module runs in single-channel mode unless you add a matching second module.
