Overview
The Kingston FURY Impact KF556S40IBK2-32 is a 32GB DDR5 laptop memory kit comprising two 16GB modules. Designed for compatible notebooks and compact systems, it uses the 262-pin SO-DIMM form factor and supports a rated data transfer rate of 5600MT/s.
Part of the Kingston FURY Impact series, this memory kit combines DDR5 technology with Plug and Play configuration support and Intel XMP 3.0 memory profiles. Its compact module design makes it suitable for compatible laptops and small-form-factor computers that support DDR5 SO-DIMM memory.
Memory Performance and Technical Information
The kit is rated for DDR5-5600 operation with CL40-40-40 timings at 1.1V. Its Plug and Play configuration allows supported systems to select appropriate memory settings automatically, subject to the capabilities of the system firmware and memory controller.
Each 16GB module uses a single-rank x8 organization. The modules also incorporate on-die ECC, a feature of DDR5 memory technology that provides error correction within the memory chips. This is distinct from system-level ECC memory functionality.
Compatibility
This kit is intended for laptops and compact computers with 262-pin DDR5 SO-DIMM slots. The system must support DDR5 memory, the individual module capacity, and the combined 32GB configuration.
DDR5 SO-DIMM modules are not interchangeable with desktop DDR5 DIMMs or older DDR4 SO-DIMMs. Verify the exact memory generation, form factor, maximum supported capacity, and supported memory speed in the device manufacturer's documentation before purchasing.
Although the modules support DDR5-5600, the actual operating speed depends on the processor, memory controller, motherboard design, and firmware configuration. Intel XMP 3.0 profile support also depends on the host platform.
Key Features
- 32GB total capacity: Two 16GB modules supplied as a matched memory kit.
- DDR5-5600 performance: Rated transfer rate of 5600MT/s with CL40-40-40 timings at 1.1V.
- Compact SO-DIMM design: 262-pin modules designed for compatible laptops and compact computers.
- Intel XMP 3.0 support: Provides memory profile support on compatible platforms.
- On-die ECC: Includes DDR5 chip-level error correction without providing system-level ECC functionality.
Applications
- Memory upgrades for compatible DDR5 laptops.
- Compact computers and mini PCs with supported DDR5 SO-DIMM slots.
- Compatible systems requiring a combined memory capacity of 32GB.
DC Supplies Product Note
Check the device manufacturer's memory compatibility documentation before ordering. In addition to supporting DDR5 SO-DIMMs, the system must accommodate two 16GB modules and the desired operating speed. Some laptops have soldered memory or a limited number of upgradeable slots, which can affect installation options.

Frequently Asked Questions
Is this memory kit compatible with every laptop?
No. The laptop must support DDR5 SO-DIMM memory and the required module capacity. Check the manufacturer's specifications for memory generation, supported capacity, and slot configuration.
Does the kit contain one 32GB module or two 16GB modules?
The kit contains two 16GB DDR5 SO-DIMM modules, providing a combined capacity of 32GB.
Will this kit operate at 5600MT/s in every compatible laptop?
Not necessarily. The achievable speed depends on the laptop's processor, memory controller, motherboard, and firmware. A system may operate the modules at a lower supported speed.
Can I install these modules in a desktop motherboard?
Only if the computer specifically supports 262-pin DDR5 SO-DIMM memory. Standard desktop DDR5 DIMM slots use a different physical form factor.
Does on-die ECC mean this is server-grade ECC memory?
No. On-die ECC corrects certain errors within the DDR5 memory chips. It does not provide the same system-level error-correction functionality as dedicated ECC memory supported by compatible server and workstation platforms.
