With the launch of the Intel’s new Skylake platform, many high end motherboards started appearing in the market with promising features and great performance. And today we have the opportunity to review one such board from GIGABYTE and my first Z170 board the GIGABYTE Z170X-Gaming G1 Motherboard.

GIGABYTE Z170X-Gaming G1 Motherboard is the top of the line motherboard from GIGABYTE based on the new LGA1151 socket supporting the Intel 6th Generation Skylake processors with great feature like dual channel DDR4 support, Intel USB 3.1 with USB Type-C, Dual PCIe Gen3 x4 M.2 Connectors with up to 32Gb/s Data Transfer, Creative certified Sound Blaster ZxRi 120+dB sound, Killer DoubleShot Pro™ X3 networking and many more.

Now let’s see what GIGABYTE Z170X-GAMING G1 board have for us.


  • Extreme Intel® USB 3.1 Controller - The Intel® USB 3.1 controller utilizes 4 PCIe Gen3 lanes, offering 32 Gb/s of total bandwidth, for uncompromised transfer speeds of up to 10 Gb/s per USB 3.1. With twice the bandwidth compared to its previous generation, and backwards compatibility with USB 2.0 and 3.0, the much improved USB 3.1 protocol is available over the new reversible USB Type-C™ and the traditional USB Standard-A connector for better compatibility over a wider range of devices.
  • Connecting the Future - USB Type-C™ - The World's Next Universal Connector. Reversible USB Type-C™ with USB 3.1. The USB Type-C™ is a new reversible connector that is loaded with useful features such as USB 3.1 support for 10 Gb/s transfer speed and DisplayPort 1.2 support to connect 4K monitors. Powered by the Intel® controller, this little port is the better USB Type-C™.
  • GIGABYTE AMP-UP Audio™ Technology - GIGABYTE Z170X-Gaming G1 motherboard is equipped with Creative Sound Blaster Certified ZxRi 120dB+ Audio and the GIGABYTE exclusive AMP-UP Audio Technology, which provides the industry's highest level of onboard audio features and technologies. With GIGABYTE AMP-UP Audio, gamers and audiophiles are able to experience crisp, ultra-realistic sound effects while gaming, and the richest possible sound experience when listening to their favorite music and movies.
  • USB DAC-UP -Clean, low-noise power for your Digital-to-Analog Audio converter -GIGABYTE USB DAC-UP provides clean, noise-free power delivery to your Digital-to-Analog Converter. DACs can be sensitive to fluctuations in power from the other USB ports, which is why GIGABYTE USB DAC-UP takes advantage of an isolated power source that minimizes potential fluctuations and ensures the best audio experience possible.
  • Killer DoubleShot-X3™ Pro – Automatically prioritize your game network needs over the fastest available connection for high quality, lag-less and uninterrupted gaming connectivity. 2 Killer GbE + 1 Killer WiFi - The Killer DoubleShot Pro™ X3 allows three killer interfaces to work together for the best networking by freeing the highest bandwidth to the most important traffic, allowing you to multitask without affecting your performance.
  • Dual PCIe Gen3 x4 M.2 – With two PCIe Gen3 x4 M.2 connectors onboard, GIGABYTE brings to the user PCI-Express connectivity for SSD devices. Delivering up to 32 Gb/s data transfer speed per connector, the dual M.2 provides an ideal storage solution as it also supports RAID modes.
  • Fast Intel® 750 Series 2.5" SSD Support via M.2 to U.2 Add-in-Card – GIGABYTE motherboards support the latest consumer NVMe SSD for truly amazing performance. Experience the future of storage performance for desktop client and workstation users with the Intel® SSD 750 Series. The Intel® SSD 750 Series delivers uncompromised performance by utilizing NVM Express over four lanes of PCIe 3.0.
  • Turbo B-Clock –Built-in Advanced Performance Tuning IC. Thanks to the onboard TURBO B-Clock Tuning IC, GIGABYTE Motherboards enable Overclockers to have the ability to change their BCLK Frequency to a desired value of their choice. With the new linear range adjustment option of the Tuning IC, ranges from 90MHz to 200MHz are now possible, so that overclockers are not limited to the 5% ranges of traditional straps.
  • Water Block Thermal Design with G1/4 Threaded Fittings - Tube connectors at each end of the heatsink provide easy integration with any water cooled system. These technologies help combat high temperatures by effectively removing heat from critical areas of the motherboard such as the CPU VRM zone, allowing it to remain cool, even when the battle heats up.
  • GC-USB3.1 BAY GIGABYTE USB3.1 5.25" Front Bay Expansion Port
  • 15 Gold Plated CPU Socket Design -GIGABYTE motherboards come equipped with a 15 micron thick gold plated CPU socket*, which means that enthusiasts can enjoy absolute reliability and longevity for the CPU socket overtime, without having any concerns about corroded pins or bad contacts.
