Kingston FURY Beast 64GB (2x32GB) DDR5-5600 CL40 Desktop Memory Kit, AMD EXPO & Intel XMP, Black

The Kingston FURY Beast KF556C40BB2K2-64 is a 64GB (2x32GB) DDR5-5600 CL40 desktop memory kit for AMD Ryzen AM5 and Intel DDR5 desktop builds that need 64GB for gaming, content creation and heavy multitasking. It ships as a matched set of 2 x 32GB modules, tested together by Kingston, so every module runs the same timings in the same system.

Out of the box the kit starts at the safe default speed stored in its SPD (DDR5-4800 CL40-39-39, 1.1V) and reaches 5600 MT/s CL40 once you enable the EXPO or XMP profile in the BIOS. The kit carries both AMD EXPO and Intel XMP profiles, so the same modules work at rated speed on either platform.

• 2 x 32GB DDR5 UDIMM modules (64GB (2x32GB) total)
• Retail packaging from Kingston
• No screws, cables or adapters are needed — the modules clip straight into the slots
• No software is required for operation

• Capacity: 64GB is comfortable for large games with browsers and voice chat in the background, 4K video timelines, big photo libraries, virtual machines and local development containers.
• Speed: the rated 5600 MT/s CL40 only applies after you enable EXPO (AMD) or XMP (Intel) in the BIOS. Without it the kit runs at the JEDEC default (DDR5-4800), which is stable but slower.
• First boot after installing DDR5 is often slow — the board trains the memory and may restart once or twice. Let it finish before assuming a fault.
• Two modules fill one slot per channel, the configuration DDR5 boards handle best. Use the slots your motherboard manual marks for two DIMMs (usually A2 and B2).
• Do not mix this kit with other modules. Different kits, even with the same label, can use different DRAM and will not be guaranteed to run at the rated speed together.
• This version uses 32Gbit DRAM in a single-rank (1Rx8) layout — fewer chips per module, which tends to be easier on the memory controller than the older dual-rank 32GB modules.

• DDR4 motherboards — DDR5 modules have a different key notch and physically do not fit DDR4 slots.
• Laptops, mini PCs and all-in-ones that use SO-DIMM slots — this is a full-size 288-pin desktop DIMM.
• Servers and workstations that require registered (RDIMM) or ECC UDIMM memory — this is non-ECC unbuffered memory.
• Prebuilt desktops with locked BIOS (many office PCs) — the modules will usually run, but only at the default DDR5-4800, because the BIOS does not offer EXPO/XMP.
