Frequently Asked Questions

Is this RAM compatible with all laptops that use DDR4 memory?

This G.Skill RipJaws kit is DDR4 SO-DIMM memory, designed for laptops and small form factor systems; however, always check your laptop's specific memory compatibility.

What does the CL19 timing mean for performance?

CL19 refers to the CAS Latency, indicating 19 clock cycles delay before data can be accessed, which is a standard timing for DDR4-2666 modules.

Can I use just one 8GB module from this 16GB kit?

Yes, you can use one 8GB module, but using both modules in a dual-channel configuration typically offers better performance.

Will installing this memory improve my laptop's speed for gaming?

While adding more RAM can help with overall system responsiveness and multitasking, the DDR4-2666 speed with CL19 timings is a moderate upgrade, and high-end gaming might benefit more from faster RAM.

What is the advantage of the 1.2V operating voltage?

The 1.2V operating voltage contributes to lower power consumption and less heat generation compared to higher voltage memory modules.

Strengths & Trade-offs

👍 Pros

This memory kit provides a total capacity of 16GB, suitable for enhancing multitasking capabilities on laptops.
The two 8GB modules allow for dual-channel memory configuration, which can improve system performance.
With a DDR4-2666 standard, this RAM offers a respectable speed for many modern computing tasks.
The SO-DIMM form factor ensures compatibility with laptops and other small form factor systems.
Operating at a low voltage of 1.2V, this memory contributes to energy efficiency in portable devices.

👎 Cons

The CL19 19-19-43 timings are on the higher side, meaning there could be a slight delay in memory access compared to lower latency kits.
With a speed of DDR4-2666, this memory may not be the fastest option available for high-performance gaming or demanding applications.
This kit consists of two modules, so if your laptop only has one available SO-DIMM slot, you won't be able to utilize the full kit.
The 16GB total capacity might be a limiting factor for users running extremely memory-intensive professional software.
As SO-DIMM memory, it is not compatible with standard desktop motherboards that require DIMM modules.
