Gigabyte Z790 AORUS MASTER (Rev. 1.0)
The Definitive E-ATX Powerhouse with 10GbE Networking, Gen 5 Storage, and Overkill VRM Power Delivery
Overview
How It Works
Power Conditioning via 105A SPS VRMs
Raw power from the power supply's dual 8-pin EPS connectors enters the digital PWM controller, stepping down smoothly across 20 phases for the VCORE to deliver stable current directly to the LGA 1700 socket.
PCIe Gen 5 Lane Distribution
The motherboard splits the processor's primary 16 PCIe 5.0 lanes; when the PCIe 5.0 M.2 slot is active, it dynamically shifts to an x8/x4 split to feed both the GPU and ultra-fast NVMe storage.
Thermal Dissipation with Fins-Array III
Heat generated by high-draw components is actively transferred through high-conductivity 8 W/mK pads into nano-carbon coated heatsinks, exploiting a multi-layered fin structure to increase surface area by over 1600%.
Signal Integrity for High-Speed DDR5
Shielded daisy-chain routing beneath the PCB surface minimizes electromagnetic interference, allowing XMP profiles to easily scale DDR5 memory clock speeds above 8000 MT/s.

Setup Tips
Flash the Latest BIOS via Q-Flash Plus
Prior to assembly, load the newest BIOS file onto a FAT32 flash drive, rename it to GIGABYTE.bin, insert it into the designated USB port, and press the Q-Flash Plus button to ensure absolute compatibility with 14th Gen CPUs.
Prioritize Core RAM Slots for High XMP Speeds
To achieve maximum stability at extreme frequencies like DDR5-7200+, ensure you populate the physical A2 and B2 memory slots (slots 2 and 4 from the socket) first.
Manage Gen 5 M.2 Lane Sharing Settings
If you are running a high-end GPU and do not explicitly need 14 GB/s NVMe storage, populate the PCIe 4.0 M.2 slots first to prevent your graphics card from running in PCIe 5.0 x8 mode.
Secure E-ATX Stand-offs
Check that your chassis has all 9 E-ATX stand-offs properly installed. Since the board is slightly wider than a standard ATX layout, ensure no loose chassis screws touch the rear aluminum backplate.
Install Marvell 10GbE LAN Drivers Early
Windows 11 may not have native out-of-the-box drivers for the Marvell AQC113C network controller. Download the driver onto a USB drive before installation to avoid setup hurdles.
