G.Skill Ripjaws 4GB DDR4-2400 CL16 SODIMM

The G.Skill Ripjaws F4-2400C16S-4GRS is a 4GB DDR4 SODIMM that wins on compatibility and stability, not speed or capacity. Owners love it, with a 4.8/5 rating and user sentiment in the 97th percentile. Prices swing from EUR 68 to EUR 160 in Europe, so shop around. It's a great budget fix for older laptops, but anyone needing real performance should look at 16GB DDR4-3200 kits instead.

Let's be honest about the numbers here. 2400 MT/s puts this module in the 29th percentile for speed, which means roughly seven out of ten memory kits in our database are faster. CL16 latency lands at the 69th percentile, so the timings are actually decent for the speed class. The 16-16-16-39 subtimings are tight enough that real-world responsiveness feels snappier than the raw bandwidth number suggests.

For a 4GB stick running at 1.20V, the performance story is about stability more than speed. This is not the module you buy to chase benchmark scores. It's the module you buy because your laptop has a single open SODIMM slot and you want it to stop swapping to disk every time you open a browser tab. In dual-channel configs with a matching stick, it handles everyday multitasking, office work, and light gaming without complaint. Just don't expect it to keep up with DDR4-3200 kits in memory-heavy workloads.

Stacked against the Corsair Vengeance RGB Pro SL, this Ripjaws stick looks positively ancient. The Corsair kit runs at 3200 MT/s with RGB lighting and comes in 16GB dual-channel configs. But here's the thing: that Corsair kit won't fit in every laptop, and it draws more power. The G.Skill's compatibility story is its real weapon. Multiple owners report choosing it over Corsair Vengeance specifically because it was more stable in their machines.

The Kingston FURY Beast KF432C16BBK2/16 is another competitor that outclasses this module on paper, with 3200 MT/s speeds and a 16GB capacity. The Team Group T-FORCE VULCAN Z and Patriot Viper Steel kits similarly offer more speed and capacity for not much more money. But all of those are desktop-oriented or higher-power modules. For laptops that need a low-voltage, low-profile SODIMM that just works, the Ripjaws holds its own despite the spec sheet gap.

Pricing on this stick is all over the map, and that's worth paying attention to. In Europe, we're seeing listings from EUR 68 up to EUR 160 across DE, ES, FR, and IT. That's a EUR 92 spread for the exact same module. If you're shopping in euros, the lower end of that range is where this makes sense. At EUR 68, it's a reasonable way to revive an older laptop. At EUR 160, you're paying premium money for a 4GB stick that's slower than most budget kits.

Canadian buyers face a similar situation, with prices ranging from CAD 107 to CAD 151 across two listings. Again, shop around. The GBP 62 listing in the UK is more in line with what this module should cost. The affordability score in our database sits at the 82nd percentile, which reflects the low-end pricing more than the high-end outliers. Bottom line: this is a value buy only if you find it at the cheaper end of the spectrum.

The G.Skill Ripjaws F4-2400C16S-4GRS is a 4GB stick of DDR4 laptop memory that's been quietly doing its job for years. It's not flashy, it's not fast by today's standards, and it's certainly not big. But it's one of those parts that just works, and that's exactly why people keep buying it. Our database puts its social proof in the 98th percentile, which means real buyers are overwhelmingly happy with this thing.

This is a budget-oriented SODIMM aimed at older laptops, thin-and-lights, or anyone who just needs to bump a machine from 4GB to 8GB without spending real money. The 2400 MT/s speed and CL16 timings are modest, but the 1.20V operating voltage means it sips power and runs cool. That matters in laptops where thermals and battery life are always fighting for headroom.

What makes this stick interesting is the mismatch between its specs and its reputation. On paper, it's a middle-of-the-road module with a capacity that lands in the bottom 10 percent of our database. But owners absolutely love it. The user sentiment score sits at 95 out of 100, and the recurring theme across reviews is compatibility. People drop this into ASUS ROG Strix, Lenovo Legion, and MSI GS63VR laptops and it just boots. No BIOS fiddling, no XMP headaches, no drama.

If you're building a new laptop or upgrading a machine that supports DDR4-3200 or faster, skip this. The 2400 MT/s speed and 4GB capacity will bottleneck anything beyond basic productivity. You'd be paying for a module that's already behind the curve. Look at 16GB DDR4-3200 kits from Kingston or Corsair instead. Similarly, if you're a gamer or content creator, this stick won't give you the headroom you need. A single 4GB module is a band-aid, not a solution. Anyone running memory-intensive applications should be looking at 16GB minimum, ideally in a dual-channel config. And if you find this module priced at the high end of the range, like EUR 160, just walk away. That's too much money for what you're getting.

If you've got an older laptop with a 4GB or 8GB config and you're not ready to replace the whole machine, this is a solid, low-risk upgrade. The compatibility track record is the headline here. Owners across multiple gaming laptop brands report drop-in success, and the 1.20V power draw means you won't be cooking your battery or your lap. Buy it at the low end of the price range and you'll feel good about it.

But if you're building a new system or upgrading a laptop that supports faster memory, look elsewhere. A 4GB stick at 2400 MT/s is a stopgap, not a foundation. For anyone doing video editing, heavy multitasking, or modern gaming, you'll want at least 16GB of DDR4-3200. This Ripjaws module is for keeping old machines alive, not for pushing new ones forward.
