Kingston FURY Renegade RGB 48GB Kit (2x24GB) DDR5-8400 CL40 Desktop Memory CUDIMM, 1.45V, Intel XMP

The Kingston FURY Renegade RGB KF584CU40RWAK2-48 is a 48GB Kit (2x24GB) 288-pin clocked unbuffered DDR5 desktop DIMM (CUDIMM) rated at 8400 MT/s with CL40 latency at 1.45V, for enthusiasts on the newest Intel desktop platform who want the highest memory speeds.

It comes as 2 matched modules of 24GB, giving 48GB in total and up to 67.2 GB/s of peak bandwidth per module (PC5-67200). A CUDIMM carries its own Client Clock Driver (CKD) that regenerates the clock signal on the module, which is what makes speeds above 8000 MT/s stable on platforms built for it.

Typical uses: a high-end Intel Core Ultra 200S gaming or creator build where memory bandwidth is part of the goal, and enthusiasts who tune memory and want headroom beyond standard DDR5 UDIMM speeds.

• 2 × 24GB DDR5 CUDIMM modules (48GB matched kit, tested together)
• Manufacturer packaging — memory installs tool-free into the slot, no cables or drivers needed (RGB control software is a free download from the manufacturer)

• Out of the box it boots at 6400 MT/s CL52 at 1.1V. Enabling XMP in BIOS is a one-click setting that loads the rated 8400 MT/s CL40 profile — the final speed depends on your CPU’s memory controller and motherboard.
• Two modules fill both channels of a dual-channel platform — install them in the slots your motherboard manual marks for two-DIMM operation (usually A2/B2).
• 48GB suits heavy content creation, large projects, virtual machines and professional applications that cache aggressively.
• Height matters with large tower air coolers: at 45 mm check the clearance under your cooler’s front fan.
• Installation takes a few minutes: power off and unplug the PC, open the side panel, release the slot latches and press each module straight down until the latches click shut on both ends.
• After installation, Windows Task Manager (Performance → Memory) shows the total capacity, the speed in MT/s and how many slots are used — a quick way to confirm everything is detected.

• Intel 600/700-series and AMD AM5 boards are not CUDIMM-validated by Kingston for this kit — they may not boot it in CKD mode or reach the rated speed
• DDR4 or DDR3 motherboards, laptops (SO-DIMM) and servers (RDIMM)
• Mixing with standard UDIMM modules in the same system
• Combining two kits for more modules — memory makers test kits as a set and do not guarantee the rated speed with mixed kits
