Description

Expert Features

  • Next-Gen DDR5 Power Boost: The Kingston FURY Beast DDR5 8GB module is engineered for modern gaming platforms with blazing 5600MT/s speeds, CL40 timings, and twice the bank architecture of DDR4 for massive throughput gains.
  • Overclocking Made Simple: Fully supports Intel XMP 3.0 profiles, including three factory-defined speed/timing presets—5600MT/s, 5200MT/s, and 4800MT/s—letting you dial performance to your system’s sweet spot.
  • Optimized Stability With On-Die ECC: Built-in ODECC corrects internal DRAM errors to maintain stability under extreme loads, whether you’re gaming at max settings, streaming in 4K+, or rendering heavy 3D scenes.
  • Efficient Dual 32-Bit Subchannels: DDR5 architecture splits workloads across two 32-bit channels, boosting efficiency and response time for multitasking and high-fps gameplay.
  • Integrated PMIC for Power Precision: The on-module Power Management IC regulates voltage directly on the DIMM, ensuring cleaner power delivery and improved overclocking headroom.
  • JEDEC-Standard Foundation: SPD is preprogrammed for DDR5-4800 CL40-39-39 at 1.1V, guaranteeing broad compatibility and stable boot behavior across modern motherboards.
  • Thermal Armor Included: A sleek black heatsink keeps temperatures in check while giving your rig a stealth-performance aesthetic upgrade.
  • Built for Longevity: Gold-contact 288-pin DIMM construction ensures excellent signal integrity and long-term reliability.
  • Perfect for Gaming, Creation, and Beyond: Whether you’re crushing ultra-settings, editing high-resolution content, or pushing heavy rendering workloads, this module elevates your system to a new tier of capability.
