The dual-channel DDR5 architecture supports two DIMM slots with speeds up to 7200 MT/s through AMD EXPO and Intel XMP profiles, accommodating up to 128GB total system memory.

Storage and Expansion

Storage connectivity includes one PCIe 4.0 x4 M.2 socket supporting 2280/2580 form factors, plus four SATA 6Gb/s ports with RAID 0, 1, and 10 support. The single PCIe x16 slot features Gigabyte's EZ-Latch quick-release mechanism for simplified graphics card installation and removal. An additional PCIe 3.0 x1 slot provides expansion flexibility.

Display and Connectivity

Triple display output support includes D-Sub (1920x1200@60Hz), DisplayPort (3840x2160@144Hz), and HDMI (4096x2160@60Hz) for integrated graphics. Network connectivity is handled by Realtek GbE LAN with bandwidth management software. USB connectivity includes two USB 3.2 Gen 1 ports on the rear panel, with additional ports available through internal headers.

Cooling and BIOS Features

Smart Fan 6 technology provides comprehensive thermal management with multiple temperature sensors, hybrid fan headers supporting PWM/DC fans up to 24W, and customizable fan curves through an intuitive BIOS interface. The fan stop feature allows complete fan shutdown below specified temperatures. Q-Flash Plus enables BIOS updates without installing CPU, memory, or graphics card—simply load the BIOS file onto a USB drive and press the dedicated button.

Audio and Build Quality

Realtek Audio CODEC with high-end audio capacitors delivers 7.1-channel HD audio. Audio Noise Guard design separates analog audio components from potential PCB-level interference. The 256 Mbit AMI UEFI BIOS supports Windows 11 and Windows 10 64-bit operating systems.

EZ-Latch
Unlock the latch of the PCIe slot easily when remove the graphics card in the PCIe slot.

Q-Flash Plus
Update the BIOS easily without installing the CPU, memory and graphics card. With GIGABYTE Q-Flash Plus, you don't need to install the CPU, memory and graphics card nor enter the BIOS menu to flash the BIOS. Just download and save a new BIOS file (rename to gigabyte.bin) on the USB flash drive, then press the dedicated Q-Flash Plus button and you're good to go!
STEP 1: Plug 24pin & 8pin power supply cable on motherboard
STEP 2: Download motherboard BIOS file and rename to "gigabyte.bin", save to USB flashdrive, and plug USB flashdrive into Q-Flash USB port
STEP 3: Press Q-Flash Plus button, and motherboard will start updating BIOS automatically.

Smart Fan 6
Smart Fan 6 contains several unique cooling features that ensure gaming PC maintain its performance while staying cool and quiet. Multiple fan headers can easily define each fan curve based on different temperature sensors across the board via intuitive user interface.

Cooling Features
High Current Support: Each fan headers support PWM and DC fan and Water Cooling Pump , and up to 24W (12V x 2A) with Over-Current Protection
Precision Control: Multiple temperature/fan speed control points for precise fan curve
Dual Curve Mode: Slope/Stair dual mode for different user scenario
Fan Stop: Fan can stop completely below users' specified temperature point

Smart Fan 6 BIOS UI
Improve fan curve UI: We increase control points from 5 to 7 and larger fan speed graph for precise and easier fan curve control.
Slope/Stair dual graph mode: Fan curve can be quickly switch with Slope and Stair modes for different user scenario. Slope is traditional and intuitive linear fan speed curve. With newly added Stair non-linear mode, fan keeps at same speed between specified temperature interval.
Manual Input: For advanced users, we provide fan speed manual input for more precise control.
EZ Tuning: Use can place 4 EZ Tuning points at rough temperature/fan speed, and Smart Fan 6 can quickly generate a fan curve.
