G.Skill Ripjaws 64GB (2x32GB) DDR5-5600 CL40 SODIMM

The G.Skill Ripjaws F5-5600S4040A32GX2-RS is a 64GB DDR5 SODIMM memory kit for laptops that delivers strong capacity and decent speed at 5600 MT/s. But the CL40 latency is mediocre and the price is painfully high at around $1,400 USD. Unless you specifically need 64GB in a notebook and find a deal, the Kingston FURY Beast kit is a better buy.

In our database, this kit's speed lands at the 77th percentile for DDR5 SODIMM memory. That's well above average, but not the top of the charts. The 5600 MT/s transfer rate is respectable for a laptop kit, especially at 1.10V. You won't see the 6400 MT/s speeds that some desktop kits hit, but for a notebook, this is a strong daily driver. The CL40-40-40-89 timings are where things get less impressive. Latency sits at the 32nd percentile, which means it's mediocre compared to other DDR5 kits. In practice, that translates to slightly slower response times in latency-sensitive tasks, though most people won't notice outside of benchmarks.

For real-world use, the 64GB capacity matters more than the timings. If you're running memory-hungry applications like Premiere Pro, After Effects, or multiple Docker containers, the extra headroom is a bigger deal than shaving a few nanoseconds off latency. The XMP 3.0 profile is easy to enable in BIOS, and the kit will boot at JEDEC defaults if your laptop doesn't support XMP. Just don't expect to manually tighten those timings much. This is a capacity play first, speed play second.

The Kingston FURY Beast KF564C32BWEAK2-64 is the most direct competitor. It's also a 64GB DDR5 SODIMM kit, but it runs at 6400 MT/s with CL32 timings. That's faster and tighter than the Ripjaws, and in our database it typically costs less. If your laptop supports 6400 MT/s, the Kingston kit is the smarter buy on paper. The Corsair VENGEANCE RGB CMH64GX5M2Y6400C32 is another option if you want RGB lighting, though that's a desktop kit and won't fit SODIMM slots. The Crucial Pro Overclocking CP2K16G64C32U5B is a 32GB kit, so half the capacity, but it's much cheaper and easier to find. If you don't need 64GB, save your money.

The KLEVV CRAS V RGB and Team Group T-CREATE EXPERT kits are also worth a look. The KLEVV kit is flashy and fast, but again, it's a desktop form factor. The Team Group kit is aimed at creators and often undercuts G.Skill on price. For laptop users specifically, the real fight is between this Ripjaws kit and the Kingston FURY Beast. And right now, Kingston wins on speed, latency, and price.

Let's be blunt. At roughly $1,400 USD, this kit is expensive. The affordability percentile is 6th, which means almost every other DDR5 SODIMM kit in our database costs less. You can find 64GB kits from Crucial or Kingston for less money, though you might give up some speed or brand cachet. The question is whether the Ripjaws name and the 5600 MT/s rating justify the premium. For most people, probably not. But if you need a matched 2x32GB kit with XMP 3.0 and you trust G.Skill's binning, the price is what it is. Laptop memory at this density has always carried a tax.

The G.Skill Ripjaws F5-5600S4040A32GX2-RS is a 64GB DDR5 SODIMM kit aimed squarely at laptop owners who need a serious memory bump. You get two 32GB sticks rated for 5600 MT/s at CL40, running at a low 1.10V. It's an unbuffered, non-ECC kit with Intel XMP 3.0 support, so it's built for notebooks and small form factor machines that take 262-pin SODIMMs. The price is the elephant in the room here. At around $1,400 USD in our database, this is not a casual upgrade. It's a workstation-class purchase for people who genuinely need 64GB in a laptop.

If you're searching for the best 64GB DDR5 SODIMM kit for a laptop, this one lands in a weird spot. The capacity is excellent, sitting in the 90th percentile for this category. The speed is solid too, at the 77th percentile. But the latency story is less exciting. CL40 at 5600 MT/s is fine, not fast. And the affordability score is rough, just the 6th percentile. You're paying a premium for density and the Ripjaws name.

So who is this for? Video editors, data analysts, developers running multiple VMs, and anyone whose laptop supports DDR5 SODIMMs and needs 64GB without buying a whole new machine. If you just want snappier Chrome tabs, this is overkill. But if your workflow is choking on 16GB or 32GB, this kit solves a real problem.

Skip this kit if you don't actually need 64GB in a laptop. Gamers, students, and general users will get zero benefit from the extra capacity and will pay a huge premium for it. Also skip it if your laptop doesn't support XMP 3.0 or DDR5 SODIMMs, since you'll be stuck at JEDEC defaults. If you need 64GB but want better speed and lower latency, the Kingston FURY Beast kit is the smarter buy. And if you're building a desktop, this SODIMM kit won't fit your motherboard at all. Look for a standard DIMM kit instead.

Should you buy the G.Skill Ripjaws F5-5600S4040A32GX2-RS? Only if you specifically need 64GB of DDR5 SODIMM memory, your laptop supports XMP 3.0, and you can't find the Kingston FURY Beast kit for less. The Ripjaws kit is well-built and has a great reputation, but the CL40 latency and the brutal price tag make it hard to recommend over faster, cheaper alternatives. If you're already running a G.Skill kit and want to max out your laptop, it's a safe choice. Just know you're paying a premium for the name and the density.

For most people, 32GB is plenty. And if you do need 64GB, shop around first. The Kingston FURY Beast kit is faster, has better timings, and usually costs less. This Ripjaws kit is a solid product in a vacuum, but the value proposition falls apart when you look at the competition.
