NVMe PCIe 4.0/3.0 M.2 ConnectorWith NVMe PCIe 4.0/3.0 x4 M.2 connector onboard, GIGABYTE Motherboards bring users to experience NVMe mode or SATA mode connectivity with delivering up to 64 Gb/s data transfer speed. Exclusive Realtek 8118 Gaming LANHigh Speed Gigabit LAN with Automatic Bandwidth Allocation Realtek 8118 LAN is a high performance and friendly network chip for gaming players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users the most comprehensive features and the fastest and smoothest Internet experience. The Industry''s Leading LAN Static-Electricity & Surge ProtectionGIGABYTE motherboards use ICs with up to 3 times the ESD resistance levels compared to traditional ICs. This helps to better protect the motherboard and its components against potential damage caused by static electricity. GIGABYTE motherboards also feature special anti-surge ICs that protect your motherboard, and your PC from any surge in power delivery that may occur, helping to ensure that your PC is equipped to deal with any potentially irregular and inconsistent power delivery. HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth - twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers. High-End Audio Capacitors GIGABYTE motherboards use high-end audio capacitors. These high quality capacitors help deliver high resolution and high fidelity audio to provide the most realistic sound effects for gamers. Audio Noise Guard GIGABYTE motherboards feature an audio noise guard that essentially separates the board''s sensitive analog audio components from potential noise pollution at the PCB level.
