Kingston Fury Renegade 48GB DDR5-8400

The Kingston Fury Renegade KF584CU40RSAK2-48 hits 8400 MT/s, the fastest desktop DDR5 speed in our database. Gaming performance scores 95.7 out of 100, and latency is top-tier at CL40. But at around $980 USD, you're paying a huge premium for that speed, and the server score of 40.8 means this kit is strictly for gaming and workstation builds.

8400 MT/s. Let that sink in. That's PC5 67200 territory, and it's the top speed we've ever recorded for desktop DDR5. The timings are 40-52-52-131, which sounds loose until you remember the clock speed. At 8400 MT/s, CL40 translates to roughly 9.5 nanoseconds of first-word latency. That's why the latency percentile lands at 95, which is outstanding for a kit this fast. The 1Rx8 configuration with 24GB modules keeps the signal path clean, and the CUDIMM design with its onboard clock driver is doing real work to keep 8400 stable.

The gaming score of 95.7 out of 100 is the headline here. Workstation performance comes in at 93.2, which makes sense because high-bandwidth memory helps with large file transfers, video editing, and 3D rendering. The feature score of 87th percentile reflects the RGB implementation with 12 LEDs per module and Kingston's Infrared Sync Technology. It's not just fast, it looks the part too. The heat spreader design is functional, not just decorative, because 1.45V generates real heat.

Against the G.Skill Trident Z5 Royal F5-6000J2636H32GX2-TR5NG, the Kingston kit absolutely destroys it on raw speed. 8400 MT/s versus 6000 MT/s is a 40% bandwidth advantage. But the G.Skill runs at lower voltage and costs significantly less. The Corsair VENGEANCE RGB CMH64GX5M2Y6400C32 offers double the capacity at 64GB and still hits 6400 MT/s, which makes it a smarter buy for workstation users who need more RAM more than they need the absolute fastest RAM. The KLEVV CRAS V RGB KD5BGUA80-60A300J is another 8000 MT/s class kit, so it's the closest competitor on speed, but the Kingston still edges it out at 8400. The Patriot Viper Xtreme 5 is in a similar position, fast but not quite this fast. If you want the crown, Kingston has it. If you want value, look elsewhere.

This is where things get painful. The US listing sits at $980, and the UK price is £1,370. That's a lot of money for 48GB of RAM, even RAM this fast. You're paying a serious premium for that 100th percentile speed. The price per gigabyte is roughly $20.42 in the US, which is steep compared to slower kits that still perform well in real-world gaming. If you're chasing benchmark records or building a no-compromise system, the value equation changes. But for most people, a 6000 MT/s or 6400 MT/s kit at half the price will deliver 90% of the experience.

The Kingston Fury Renegade KF584CU40RSAK2-48 is a 48GB (2x24GB) DDR5 kit running at 8400 MT/s with CL40 timings. That speed puts it in the 100th percentile in our database, which means it's literally the fastest desktop memory we've tracked. The latency story is nearly as strong at the 95th percentile, so you're not sacrificing responsiveness for raw bandwidth. This is a CUDIMM kit, which is the newer standard that helps stabilize those extreme speeds on Intel platforms with XMP 3.0.

But here's the thing. This kit is not for everyone. The 1.45V operating voltage is high, the price is eye-watering in every currency we track, and the server score of 40.8 out of 100 tells you exactly what this memory is not built for. If you're building a gaming rig or a workstation where every frame and every render second counts, this is a serious contender. If you're running a home server, keep scrolling.

If you're building a server or a NAS, skip this. The 40.8 out of 100 server score is one of the weakest we've seen for this category, and you'd be paying a fortune for speed you can't use. Budget builders should also look elsewhere. At $980 USD, this kit costs more than many entire mid-range PCs. And if your motherboard doesn't officially support 8400 MT/s, you're gambling with stability. This is a kit for enthusiasts with deep pockets and compatible hardware, not for practical builds.

The Kingston Fury Renegade KF584CU40RSAK2-48 is the fastest desktop DDR5 kit we've ever tested, and the numbers back that up. 8400 MT/s at CL40 with a 95.7 gaming score is exceptional. But the price is a serious hurdle. At $980 USD or £1,370 GBP, you're paying a massive premium for that last bit of speed. The 40.8 server score also means this is a one-trick pony, it's for gaming and workstation builds only. If you have the budget and a motherboard that can handle it, this is the kit to beat. If you're building something more practical, a 6400 MT/s kit will leave a lot more money in your pocket.
