Kingston (KF588CU42RW-24)

The Kingston FURY Renegade KF588CU42RW-24 is the fastest DDR5 stick in our database at 8800 MT/s with excellent CL42 latency. It's a single 24GB module aimed at overclockers and enthusiasts. At $198 USD it's not cheap, but nothing else comes close to this speed.

The headline number here is 8800 MT/s, and in our database that puts it at the 100th percentile for speed. It's the absolute best right now. Latency sits at CL42, which sounds high on paper but is actually a standout for this speed class, landing in the 95th percentile. The 24GB capacity is solid but not huge, about average for a single stick. One thing to note: this is a single-rank 1Rx8 module, so you'll want to pair it carefully if you plan to add more later. The 1.4V requirement is also on the higher side, so make sure your board can actually feed it.

Against the G.Skill Trident Z5 RGB at 7600 MT/s, the Kingston wins on raw speed but gives up some capacity flexibility since the G.Skill comes as a 2x16GB kit. The Corsair Vengeance RGB at 6000 MT/s CL28 is a much better value for most builders, but it's not even in the same speed conversation. The Crucial Pro Overclocking kit and Team Group T-CREATE EXPERT are both more budget-friendly but top out well below 8800 MT/s. If you want the fastest single stick on the market, Kingston is the only one here playing at this level.

At $198 USD for a single 24GB stick, this is not a budget buy. The affordability percentile sits at 48, so it's right around average for what you get. But you're paying for the absolute top speed tier, and that's never cheap. If you need 8800 MT/s, this is the price of admission. If you don't, there are cheaper ways to get 24GB of DDR5.

Kingston's FURY Renegade KF588CU42RW-24 is a single 24GB DDR5 stick running at a frankly ridiculous 8800 MT/s. That's the kind of speed that makes our database sit up and pay attention. It's aimed squarely at overclockers and enthusiasts who want to push their Intel platform to the edge without running a full four-stick setup.

Skip this if you're building a workstation or server. The server score is a brutal 28.2 out of 100, one of the worst we've seen for that use case. Single-rank, single-stick, high-voltage memory is not what you want for stability-critical workloads. Also skip it if you're on a budget, since $198 for 24GB is a tough sell when 32GB kits at lower speeds cost less.

This is for the overclocker who wants to see how far their Intel board can go. The 8800 MT/s speed is genuinely best-in-class, and the CL42 latency is impressive for that speed. But it's a single stick, so you're either buying two for 48GB or accepting single-channel performance. If you're building a high-end gaming rig and want the absolute fastest memory available, this is it. Just know you're paying a premium for the privilege.
