G.Skill Ripjaws V F4-4000C18D-32GVK Review

The G.Skill Ripjaws V F4-4000C18D-32GVK is one of the highest-frequency Ripjaws V kits G.Skill sells, rated at DDR4-4000 CL18 for platforms with memory controllers strong enough to hit that speed reliably.

DDR4 builds chasing maximum frequency before moving to DDR5. Not for boards whose QVL tops out below 4000MT/s. Skip if you want RGB.

Performance and Timings

At DDR4-4000 CL18 (18-22-22-42), this kit lands at roughly 9.0ns of true first-word latency, a figure worth checking against any kit you're cross-shopping rather than judging by CAS number alone.

Compatibility

Rated timings load via Intel XMP 2.0 with a single BIOS toggle; outside that profile the kit boots at JEDEC defaults on any DDR4 platform. Confirm your motherboard's QVL and populate matched slots for dual/quad-channel operation.

Module Count and Rank

Ships as 2 x 16GB modules for a 32GB total; buy the full kit as one matched set rather than pairing separately purchased sticks, since G.Skill does not guarantee cross-kit compatibility.

Design and Build

Matte Black aluminum heat spreader, finished without RGB for a lower profile and simpler build.

Overclocking and BIOS Setup

Check your motherboard's QVL for 4000MT/s support before buying; enable Intel XMP 2.0 to load the CL18 profile once confirmed.

Comparison to Alternatives

Against the G.Skill Ripjaws V F4-3600C16D-32GVK already in this catalog and the G.Skill Trident Z Neo F4-3600C16D-32GTZN already in this catalog, this Ripjaws V kit is worth weighing on price-per-GB, rated timings, and whether the extra RGB or premium finish actually matters for your build before paying a premium for either.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating7 / 10

Best for

  • DDR4 builds chasing the highest frequency Ripjaws V offers, ahead of a move to DDR5.
  • Platforms with strong memory controllers that can reliably hit 4000MT/s on DDR4.

Not for

  • New 2026 builds; DDR5 is the better long-term platform at this point.
  • Boards whose QVL tops out below 4000MT/s; check compatibility before buying.
  • RGB-focused builds; Ripjaws V ships without lighting.
