G.Skill Ripjaws V 32GB (2x16GB) 4000MHz
Who this is for: builders after 32GB of DDR4 at 4000MHz for modern gaming, content creation and comfortable multitasking — it chases raw transfer rate and needs a capable memory controller and board to hit its rated profile.
The G.Skill Ripjaws V 32GB (2x16GB) 4000MHz is a 32GB DDR4 dual-channel kit rated at 4000MHz with CL18 timings.
At 4000MHz and CL18, the real-world payoff shows up in latency-sensitive gaming and everyday responsiveness, where DDR4 still holds up well. G.Skill has a long record of binning its top kits aggressively before they ship. Before buying, confirm your motherboard supports 32GB in the configuration you plan to run.

Frequently Asked Questions
Will the G.Skill Ripjaws V 32GB (2x16GB) 4000MHz run at 4000MHz out of the box?
Not automatically. Every module boots at a JEDEC baseline first, so you need to enable the XMP or EXPO profile in BIOS to reach 4000MHz at CL18. If the system fails to post, clear CMOS and try one speed step lower.
Is 32GB enough for my build?
32GB is the recommended amount for modern gaming and everyday content work — comfortable headroom for most builders without paying for capacity you won't use.
What does CL18 actually mean here?
CL18 is the CAS latency: the number of clock cycles between a read request and the first data returned. Because 4000MHz clocks faster than older kits, the same CL number represents less real time. True latency in nanoseconds, not the CL figure alone, is what to compare.
Can I mix this with memory I already own?
You can, but it is not recommended. Mixing kits means the memory controller has to find settings that satisfy every module, so you usually end up below the 4000MHz rating. Buying 32GB as a single matched kit avoids that entirely.
