Kingston FURY Impact DDR5 64 GB (2 × 32 GB) 5600 MHz CL40 – Model KF556S40IBK2‑64

The Kingston FURY Impact DDR5 64 GB kit (2 × 32 GB) at 5600 MHz with CL40 latency (Model: KF556S40IBK2‑64) is engineered for high‑performance laptops and small form‑factor systems compatible with DDR5 SO‑DIMM memory. With a total capacity of 64 GB, blistering 5600 MT/s (PC5‑44800) speed, and low‑voltage operation at 1.1 V, this kit offers excellent future‑proofing and performance head‑room for gaming, content creation, and multitasking. :contentReference[oaicite:1]{index=1}

Key Features

• Capacity: 64 GB (2 modules × 32 GB) :contentReference[oaicite:2]{index=2}
• Speed / Bandwidth: 5600 MT/s (PC5‑44800) :contentReference[oaicite:3]{index=3}
• CAS Latency (CL): CL40 (40‑40‑40 timings typically) :contentReference[oaicite:4]{index=4}
• Voltage: 1.1 V — lower power draw for laptops/portable systems. :contentReference[oaicite:5]{index=5}
• Form Factor: 262‑pin SO‑DIMM (for laptops/compact desktops) :contentReference[oaicite:6]{index=6}
• Other features: On‑die ECC, Intel XMP 3.0 support, Plug & Play automatic over‑clocking to rated speed. :contentReference[oaicite:7]{index=7}

Benefits

• With 64 GB of memory, you can run large workflows, multiple virtual machines, heavy multitasking, gaming and content creation without slowing down due to memory bottlenecks.
• The 5600 MT/s speed gives significantly higher bandwidth compared to older DDR4 modules or lower‑speed DDR5 modules—beneficial for modern CPUs and integrated graphics setups.
• Operating at just 1.1 V helps reduce power consumption and heat output—important in laptops, ultra‑compact PCs or systems with thermal constraints.
• The dual‑module kit (2×32 GB) enables dual‑channel operation when supported, boosting memory performance further.

Compatibility & Notes

• Ensure your laptop or mini‑PC supports DDR5 SO‑DIMM modules and can run at or above 5600 MT/s. If your system only supports lower speeds, this kit will down‑clock accordingly (e.g., to 4800 MT/s or 5200 MT/s). :contentReference[oaicite:8]{index=8}
• Because this is a high‑speed 64 GB (2×32GB) dual‑rank kit, some systems may default to lower speeds (5200 MT/s or below) for stability. For best results check BIOS version and memory support list. :contentReference[oaicite:9]{index=9}
• To activate full rated speed (5600 MT/s CL40), you may need to enable XMP/DOCP profile in BIOS. The kit is XMP 3.0 certified. :contentReference[oaicite:10]{index=10}
• Mixing memory modules of different speeds, brands, or specifications can lead to system instability or automatic downclocking—using a matched kit like this is recommended for optimal performance.

Package Contents
