CL22 vs CL18 DDR4 RAM Comparison
Memory Speed
The G.SKILL Ripjaws kit offers a higher memory speed of 3200MT/s. This is a significant increase over the Corsair Vengeance kit, which runs at 2666MHz. For laptop users, this difference can translate to faster data transfer rates between the RAM and the processor. If your workflow involves heavy multitasking or large file transfers, the 3200MT/s speed provides a tangible performance edge. The Corsair kit is still capable for general use, but the G.SKILL option delivers superior bandwidth potential for compatible systems.
CAS Latency
Latency measures the delay before data is available to the CPU. The Corsair Vengeance kit features a lower CAS Latency of CL18. In contrast, the G.SKILL Ripjaws kit has a higher latency of CL22. Lower latency generally means quicker response times for specific tasks. While the G.SKILL kit is faster in raw speed, the Corsair kit responds more quickly to individual requests. For gaming or applications sensitive to latency, the CL18 rating on the Corsair module provides a slight advantage in responsiveness.
Compatible Device
Both kits are designed for laptops using SO-DIMM slots. The Corsair Vengeance kit is explicitly listed as compatible with 6th and 7th generation Intel Core i5 and i7 notebooks. The G.SKILL Ripjaws kit is described as suitable for laptops and notebooks but does not specify a generation. If you have a specific older Intel laptop, the Corsair kit guarantees compatibility with its stated generations. For newer systems, both should work, but the Corsair listing provides clearer guidance for older hardware owners.
Overclocking Profile
The Corsair Vengeance kit highlights an auto-overclocking feature with compatible notebooks, requiring no BIOS configuration. This simplifies the process of achieving higher speeds on supported hardware. The G.SKILL Ripjaws kit does not mention auto-overclocking capabilities in its provided specifications. It relies on standard JEDEC default SPD speeds or manual configuration via the manufacturer's QVL. If you want a plug-and-play experience that might boost performance automatically, the Corsair kit offers a distinct advantage for users who prefer not to tweak BIOS settings.
ECC Support
Both memory kits are Non-ECC. This means they do not include Error Correcting Code, which is typically found in server or workstation memory. For standard laptop usage, Non-ECC is the norm and provides no disadvantage. Neither product offers ECC support, so this aspect does not differentiate them. You can expect standard consumer-grade performance from both. The lack of ECC is consistent with their target market of consumer laptops rather than enterprise systems.
Which DDR4 RAM Kit Fits Your Needs
Users needing maximum bandwidth for multitasking
The G.SKILL Ripjaws kit delivers 3200MT/s memory speed. This higher frequency allows faster data transfer between your processor and memory. You benefit from improved performance in memory-intensive laptop tasks. The CL22 latency is standard for this speed tier. This kit prioritizes raw throughput for smoother system operation.
Owners of 6th or 7th gen Intel laptops
The Corsair Vengeance kit is explicitly designed for 6th and 7th generation Intel Core i5 and i7 notebooks. It features auto-overclocking capabilities that require no BIOS configuration. This ensures compatibility and ease of installation for these specific older laptop models. It provides a reliable upgrade path for legacy systems.
Buyers seeking lower latency for responsiveness
The Corsair Vengeance kit offers a CL18 CAS latency. This is lower than the G.SKILL Ripjaws CL22 latency. Lower latency means the memory responds faster to requests from the CPU. This can improve system responsiveness in everyday computing tasks. The trade-off is a lower overall memory speed of 2666MHz compared to the 3200MT/s option.
