G.Skill Ripjaws S5 32GB (2x16GB) DDR5-6400 CL32 Black

The G.Skill Ripjaws S5 is a 32GB DDR5 memory kit running at 6400 MT/s with CL32 timings, making it one of the fastest desktop RAM options available. XMP 3.0 setup is easy and reliable, especially on Intel platforms. Just shop around, because prices vary wildly between vendors.

The headline numbers are 6400 MT/s and CL32 (32-39-39-102) at 1.40V. That's fast. In our database, this kit lands in the 95th percentile for speed, which means it's among the absolute best DDR5 kits you can buy right now. Latency is also a standout at the 88th percentile, so you're getting both high bandwidth and reasonably tight timings for the speed.

In practice, that translates to snappy load times and solid frame pacing in games, especially on Intel platforms where XMP 3.0 profiles tend to just work. Buyers consistently report hitting the advertised 6400 MHz speed on Z790 boards without fiddling. On AMD AM5 systems, you might see longer initial boot times due to memory training, but once it's settled, stability is generally good. One thing to keep in mind: if you plan to populate all four DIMM slots, expect to drop the speed. That's a DDR5 platform limitation more than a G.Skill issue, but it's worth knowing before you buy a second kit.

The Ripjaws S5 goes head to head with a few notable kits. The Kingston FURY Beast KF564C32BWEAK2-64 offers similar speed but doubles the capacity to 64GB, which might matter if you're doing heavy workstation tasks. The Corsair VENGEANCE RGB CMH64GX5M2Y6400C32 is the flashy alternative, same 6400 MT/s and CL32 but with RGB lighting if you want your build to glow. The Crucial Pro Overclocking CP2K16G64C32U5B is another 32GB option at the same speed, often priced more aggressively.

Where the Ripjaws S5 stands out is its no-nonsense approach. It's low-profile, which matters if you're running a big air cooler like a Peerless Assassin. Buyers have confirmed it fits under that cooler without clearance issues. The Team Group T-CREATE EXPERT and KLEVV CRAS V RGB are also in the mix, but the G.Skill kit's combination of speed, latency, and proven XMP reliability keeps it competitive. If you want RGB, go Corsair. If you want more capacity, go Kingston. If you want a clean, fast, reliable kit that just works, the Ripjaws S5 is hard to beat.

Value is the trickiest part of this review. The Ripjaws S5 is not a cheap kit. Our database puts its affordability at the 16th percentile, which means it's more expensive than most DDR5 options out there. And the price spread is genuinely wild. In the US, you'll see it listed anywhere from USD 600 to USD 721, with Newegg typically offering the best deal in our data. Canadian buyers have it even rougher, with CAD prices ranging from CAD 600 to CAD 1,356 across four stores. That's more than double the low end. If you're paying CAD 1,356 for this kit, you're getting taken for a ride. Shop around, and don't be afraid to wait for a price drop. DDR5 prices have been falling, and several owners mention feeling burned after buying at peak pricing.

The G.Skill Ripjaws S5 is a 32GB (2 x 16GB) DDR5 desktop memory kit aimed squarely at gamers and PC builders who want fast RAM without paying for flashy RGB. It runs at 6400 MT/s with CL32 timings, which puts it near the top of the charts for DDR5 speed right now. The kit uses Intel XMP 3.0, so getting it to the advertised speed is usually a one-click affair in the BIOS.

This kit sits in a weird price spot. Our database shows USD listings ranging from USD 600 to USD 721 across three US vendors, and CAD listings swinging wildly from CAD 600 to CAD 1,356 across four Canadian stores. That's a huge spread, and it means shopping around matters more than usual here. Newegg tends to have the best US pricing in our data.

If you're asking whether the Ripjaws S5 is good for gaming, the short answer is yes. Our scoring puts it at 91.8 out of 100 for gaming, which is excellent. Workstation performance is also strong at 85.8. The weakest area is server use at 37.5, but that's not what this kit is for.

Skip this kit if you're on a budget, because the affordability score is rough and there are cheaper DDR5 options that get you 90% of the performance. Also skip it if you need 64GB or more, since running four sticks of this will force lower speeds anyway. If you're building a server or a system where stability under heavy sustained load matters more than raw speed, look at ECC memory instead. And if you want RGB lighting in your build, the Corsair VENGEANCE RGB kit gives you the same speed with more flash.

Should you buy the G.Skill Ripjaws S5? If you're building a high-end gaming rig or a workstation that benefits from fast memory, and you can find it at a reasonable price, yes. The performance is genuinely excellent. 6400 MT/s with CL32 timings puts it in the top tier of DDR5 kits, and the XMP 3.0 profile makes setup painless on Intel boards. AMD users will deal with some initial boot time quirks, but that's par for the course with AM5.

The catch is price. This kit is not affordable by any stretch, and the vendor-to-vendor spread is absurd. If you see it at the low end of the range, grab it. If you're looking at the high end, wait or look elsewhere. The Crucial Pro Overclocking kit offers similar specs and often undercuts G.Skill on price. But for pure speed and reliability, the Ripjaws S5 delivers exactly what it promises.
