Quad-channel DDR5 kit for high-capacity desktop

Kingston FURY Beast KF552C40BWK4-128 provides 128 GB of DDR5 memory across four 32 GB modules. The kit runs at 5200 MT/s with CL40 timings and 1.25 V. Intel XMP 3.0 profiles are supported for automatic configuration on compatible platforms. It targets users who need large memory capacity for workstations or high-end gaming rigs.

Suited to builders with DDR5 motherboards

The 288-pin DDR5 form factor fits current Intel 500, 600 and 700 series boards as well as AMD 500, B550, B650, X570 and X670 platforms. Systems limited to two DIMM slots cannot use all four modules. Users who need lower latency or higher clock speeds should look at alternative kits.

The 5200 MT/s speed rating determines platform

Motherboards must support DDR5-5200 or higher to run the kit at its rated frequency. If the board tops out at a lower data rate the modules will downclock automatically. Verify the memory QVL for four-module population before purchase.

FeaturesKingston FURY KF552C40BWK4-128 is a kit of four 4G x 64-bit (32GB) DDR5-5200 CL40 SDRAM (Synchronous DRAM) 2Rx8, memory module, based on sixteen 2G x 8-bit FBGA components per module. Each module kit supports Intel® Extreme Memory Profiles (Intel® XMP) 3.0. Total kit capacity is 128GB. Each module has been tested to run at DDR5-5200 at a low latency timing of 40-40-40 at 1.25V. The SPDs are programmed to JEDEC standard latency DDR5-4800 timing of 40-39-39 at 1.1V. Each 288-pin DIMM uses gold contact fingers.

Questions about this item

Will this 288-pin DDR5 kit fit my motherboard?

The modules use the standard 288-pin DDR5 form factor, so they install in any desktop board with DDR5 slots.

What do I need in the BIOS to reach 5200 MT/s?

Enable the Intel XMP 3.0 profile; the kit is programmed with a single 5200 MT/s CL40 profile at 1.25 V.

Can I run all four 32 GB modules together on a dual-channel board?

Yes — the quad-channel kit will operate in dual-channel mode when populated across the four slots of a dual-channel platform.
