Features

Low latency for exceptional DDR4 performance - HyperX Savage DDR4 is a superior combination of fast speeds and aggressive timings. It complements Intel's 2, 4, 6 or 8 core processors for faster video editing, 3D rendering, gaming and AI processing.

Built-in Intel XMP profiles are optimized for Intel 100 series chipsets and X99 motherboards. Users can easily overclock their platforms simply by selecting a profile, with no need for manual timing adjustments in BIOS.

Lower power consumption compared to DDR3 - with 1.2V or 1.35V only for all parts. Its lower power requirement results in less heat, higher reliability and a cooler and quieter PC.

Made from high quality die-cast aluminum, provides enhanced thermal dissipation for greater reliability. Its low profile helps avoid clearance issues with CPU coolers, and its asymmetrical design and diamond-cut finish stand out in the crowd.
