Kingston FURY Impact 32GB DDR5-4800 CL38 SODIMM Black

A single 32GB DDR5 SODIMM that runs at 4800 MT/s with Plug N Play ease and a laptop-friendly 1.1V. The CL38 latency is mediocre, but the capacity density and compatibility are the real selling points. Pricing varies wildly from EUR 550 to EUR 796, so shop carefully. Best for laptop users who need lots of RAM without BIOS tinkering.

The 4800 MT/s speed is respectable for a SODIMM, especially one running at just 1.1V. That low voltage is worth paying attention to. Lower voltage means less heat, and less heat in a cramped laptop chassis means the memory is less likely to thermal throttle during long renders or gaming sessions. The 68th percentile speed ranking puts it in the solidly above average camp, but it's not going to blow the doors off anything. It's a workhorse, not a racehorse.

The CL38 latency is where this stick shows its budget roots. At 27th percentile, it's one of the slower kits we've tracked in terms of raw latency. In practice, that means slightly longer delays when the CPU is waiting on memory, which can show up as a few percent lower frame rates in games or marginally slower export times in Premiere. But here's the thing: for a laptop, especially one running at JEDEC speeds, CL38 at 4800 MT/s is completely normal. The real-world impact is small, and the Plug N Play behavior means you're actually getting the rated speed, which isn't always a given with laptop memory.

Stacked against the competition, the Kingston FURY Impact occupies an interesting niche. The Corsair VENGEANCE RGB and G.Skill Ripjaws S5 kits are desktop memory running at much higher speeds, 6400 MT/s territory, with tighter latencies. But those won't fit in a laptop. The Crucial Pro Overclocking and Team Group T-CREATE EXPERT kits are also desktop-focused. So in the SODIMM space, this Kingston stick is competing more on capacity and compatibility than on raw performance.

The KLEVV CRAS V RGB is the closest philosophical competitor, though it's also a desktop kit. What the Kingston really has going for it is the single-stick 32GB density. Most competing laptop kits top out at 16GB per stick, so if you need 64GB total in a two-slot laptop, this is one of the few ways to get there without selling a kidney. The trade-off is that you're stuck at CL38, while faster desktop kits are hitting CL32 or lower. For a laptop, though, that's a moot point. You can't put a desktop DIMM in a SODIMM slot no matter how much you want to.

Pricing on this stick is genuinely weird. In Europe, you'll find it anywhere from EUR 550 to EUR 796 depending on which store you hit. That's a EUR 246 spread for the exact same part number, which is either a great opportunity or a trap depending on how much you like comparison shopping. The best deal in our data comes from the DE listings at the lower end of that range. If you're paying the high end, you're getting taken for a ride.

At the lower end of that EUR range, you're paying a premium for the convenience of a single 32GB stick and the Plug N Play behavior. That's not unreasonable, but it's worth remembering that the affordability percentile is just 27th. This is not a budget kit. You're paying for capacity density and laptop compatibility, not raw speed. If you can live with two 16GB sticks instead, you'll likely find better latency and lower prices elsewhere.

Kingston's FURY Impact line is their answer for laptops and small form factor machines that need a serious memory bump without the desktop-sized heat spreaders. This particular stick, the KF548S38IB-32, is a single 32GB DDR5 SODIMM running at 4800 MT/s. That's a lot of capacity in one slot, which matters if your laptop only has two slots and you want to leave room to grow later. It's aimed squarely at people who edit video on the go, run virtual machines, or just keep 200 browser tabs open and wonder why their machine is crying.

The headline feature here is the Plug N Play overclocking. Kingston says it'll automatically hit 4800 MT/s at 1.1V without you having to dig into the BIOS and enable an XMP profile. For laptop owners, that's a big deal. Most laptops lock down memory overclocking entirely, so a stick that just works at its rated speed out of the box is genuinely useful. It's also Intel XMP 3.0 certified, so if your machine does expose those settings, you have a fallback.

But let's be honest about the specs. CL38 latency at 4800 MT/s is not going to win any benchmark trophies. In our database, the latency lands in the 27th percentile, which is mediocre territory. The speed is solid at the 68th percentile, and the capacity is well above average at the 71st. So you're getting a big, reasonably fast stick that trades raw responsiveness for compatibility and ease of use. For most laptop workloads, that's a fine trade. For chasing frame rates in a gaming laptop, maybe not.

If you're building a desktop, skip this entirely. It's a SODIMM, so it physically won't fit in a standard desktop motherboard. You'd be better off with a desktop kit like the Corsair VENGEANCE RGB or G.Skill Ripjaws S5, which offer much higher speeds and tighter latencies for similar or less money. The Kingston's advantages are all about laptop compatibility, and none of that matters in a tower.

Also skip it if you're on a tight budget. The affordability percentile is just 27th, and the price spread means you could easily overpay by EUR 200 if you're not careful. If you don't need 32GB on a single stick, a pair of 16GB SODIMMs will likely cost less and might even give you better latency. And if your laptop already has 16GB and you're just browsing the web, save your money. This is a lot of RAM for most people.

If you have a laptop with two SODIMM slots and you need 32GB now with room to hit 64GB later, this Kingston stick is a solid choice. The Plug N Play behavior means it'll actually run at 4800 MT/s without a fight, and the 1.1V voltage is kind to your laptop's cooling system. It's not the fastest memory we've ever tested, but it's reliable, dense, and easy to live with.

For gamers chasing every last frame, look elsewhere. The CL38 latency will leave a few percent on the table compared to tighter kits, and if your laptop supports XMP, you might find faster SODIMMs with better timings for similar money. But for content creators, developers running VMs, or anyone who just needs a lot of RAM in a small machine, this is a practical, no-drama upgrade. Just shop around. The price spread on this thing is wild.
