Overview

The G.Skill Ripjaws 4 DDR4-2800 (F4-2800C16D-16GRR) is a 16GB dual-channel memory kit consisting of two matched 8GB DIMMs, engineered for enthusiast-grade performance on Intel X99 platforms. Running at 2800MHz with CL16-16-16-36 timings and a standard 1.2V operating voltage, it strikes a practical balance between speed and compatibility. The kit is XMP-ready, meaning achieving its rated speed is as simple as enabling a single BIOS setting rather than manually configuring frequency and timing parameters.

Wrapped in G.Skill's signature red aluminum heat spreaders, the Ripjaws 4 modules provide effective thermal dissipation during sustained operation while adding a clean aesthetic to open or windowed builds. As a dual-channel kit, both modules have been tested together at the factory to ensure stable, matched performance. For users running X99-based workstations or gaming systems who need fast, reliable memory without pushing into extreme overclocking territory, this kit offers a well-rounded combination of speed, capacity, and hassle-free operation.
