G.Skill Ripjaws V 32GB (4x8GB) DDR4-4000 CL18 Black

The G.Skill Ripjaws V F4-4000C18Q-32GVK is a 32GB quad-channel DDR4 kit running at 4000 MT/s with CL18 timings. It ranks in the 98th percentile for latency, making it one of the best DDR4 options for gaming and workstation use. Pricing is premium, with USD 323 in the US and a wild CAD 535 to CAD 961 spread in Canada. Buy it if you're upgrading an older Intel quad-channel system, but skip it for new builds.

The headline number is 4000 MT/s, which puts this kit in the 65th percentile for speed. That's above average, but the real story is the latency. CL18 at 4000 MT/s works out to 9 nanoseconds of first-word latency, and that's why it ranks in the 98th percentile. For gaming, that means snappier frame times and fewer hitches in CPU-bound scenarios. For workstation tasks like video editing or large batch photo work, the bandwidth helps keep large files moving.

But here's the thing: quad-channel support matters more than raw speed on X99 and some older HEDT platforms. Four 8GB sticks let you populate all four channels, which doubles memory bandwidth compared to dual-channel. That's a bigger real-world win than the jump from 3600 to 4000 MT/s. On a Z170 board, you're limited to dual-channel, so the benefit is mostly from the higher frequency and tight timings. Either way, this kit is a meaningful upgrade over typical 3200 CL16 DDR4.

Compared to the Kingston Fury Renegade KF564C32RWAK2-32, the G.Skill kit is playing a different game. The Kingston is DDR5-6400, which is faster on paper, but it's a dual-channel kit. If you're on an older quad-channel platform like X99, the G.Skill is the better fit. The Corsair Vengeance RGB CMH32GX5M2B6000C28 is also DDR5, with tighter CL28 timings, but again, it won't work in a DDR4 board.

Against the Crucial Pro Overclocking CP2K16G64C32U5B and the Team Group T-CREATE EXPERT CTCWD532G6400HC32ADC01, both DDR5 kits, the G.Skill's advantage is compatibility and latency. CL18 at 4000 MT/s is excellent for DDR4, and the 98th percentile latency ranking beats what most DDR4 kits achieve. The KLEVV CRAS V KD5AGUA80-60A300G is another DDR5 option. If you're building new, DDR5 makes more sense. If you're upgrading an existing DDR4 system, especially a quad-channel one, the G.Skill is a strong choice.

Value is where this kit gets complicated. The affordability score is 34th percentile, which means it's priced above most DDR4 kits in our database. In the US, you're looking at USD 323 for 32GB. In Europe, EUR 360. In the UK, GBP 467. Those are all premium prices for DDR4 in a world that's moved on to DDR5.

The Canadian pricing is a mess. Two listings range from CAD 535 to CAD 961, a spread of CAD 426 for the exact same kit. If you're in Canada, shop carefully. The CAD 535 listing is the obvious choice, and the CAD 961 one is frankly absurd. Newegg is the retailer mentioned in the data, and their listing is the one to watch. At the lower end of that range, the value proposition is reasonable for a high-speed quad-channel kit. At the high end, you're paying DDR5 money for DDR4.

The G.Skill Ripjaws V F4-4000C18Q-32GVK is a 32GB DDR4 kit aimed squarely at enthusiasts who are still squeezing life out of older Intel platforms. It's a quad-channel setup, four matched 8GB sticks, running at 4000 MT/s with CL18 timings. That's a serious speed for DDR4, and it lands in the 98th percentile for latency in our database. If you're on Z170, X99, or a later Intel board that supports XMP 2.0, this kit is built to wake things up.

Who's this for? Gamers and workstation users who want high bandwidth without jumping to DDR5. The gaming score sits at 71.3 out of 100 and workstation at 70.2, both solid. But the budget score of 68.4 hints at the trade-off: this isn't cheap RAM. You're paying for the speed and the quad-channel compatibility, not just capacity.

What makes it interesting is the timing. CL18 at 4000 MT/s is tight for DDR4. The full timings are 18-22-22-42 at 1.35V, which is the standard XMP voltage. That means you can likely just enable XMP and go, no manual tuning required. The black Ripjaws V heat spreaders are low-profile enough to fit under most air coolers, which is a practical plus for a kit this fast.

If you're building a new PC in 2024 or later, skip this kit. DDR5 is the current standard, and spending USD 323 or more on DDR4 doesn't make sense when DDR5 kits are available at similar prices. The Kingston Fury Renegade and Corsair Vengeance DDR5 options in our comparison data are better choices for new builds.

Also skip this if you're on a budget. The affordability score of 34th percentile means there are plenty of cheaper 32GB DDR4 kits that will do the job for everyday use. And if you're building a server or NAS, this is the wrong tool entirely. The 32.1 server score tells you everything you need to know. Look for ECC memory instead.

If you're still running an Intel X99 or Z170 system and want to max out your memory performance, this kit is a great fit. The quad-channel support and 4000 MT/s speed will breathe new life into an older workstation or gaming rig. The tight CL18 timings mean you're getting top-tier DDR4 latency without manual overclocking.

But if you're building a new system, skip it. DDR5 is the future, and at these prices, you're not saving money by sticking with DDR4. The server score of 32.1 also makes this a poor choice for any kind of server or homelab use. For gamers and workstation users on compatible Intel platforms, though, this is one of the best DDR4 kits you can buy.
