Smart Fan 5

With Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

All Hybrid Fan Pin Headers

• All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.
• Supports up to 2 amps with built-in overcurrent protectiona must for high-end high current fans.

New Smart Fan 5 Software

Choose from different modes, Quiet to Full Speed, to match your system usage scenario. For each fan or pump, you can use the intuitive fan curve to define trigger thresholds and corresponding fan speeds.

Enhanced BIOS Interface

The enhanced BIOS interface also has the advanced features seen in the Smart Fan 5 UI, such as: the ability to set triggers based on different temperature sensors on the board, fan curve definition and the temperature interval setting, which can prevent fan rotation noise caused by sudden temperature changeall without having to load Windows.

Ambient LED

Ambient lights are now programmable, You can have them beat to the rhythm of the music you are listening to, or pulse at a soothing pace to create an atmosphere that enhances the environment of your game, movie or music.

 

 

ALC 1220 120dB SNR HD Audio with Smart Headphone Amp

Exceptional audio listening experience with 120dB SNR andsupport for DSD128 hardware decode.

Smart Headphone Amp automatically adjusts volumes based on detected headphone impedance.

 

Smart Headphone Amp

Automatically detects impedance of your head-worn audio device, whether earbuds or high-end headphones to provide optimal audio dynamicspreventing issues such as low volume and distortion.

 

 

USB DAC-UP 2

 

GIGABYTE improves upon USB DAC-UP technologies with USB DAC-UP 2.
USB DAC-UP 2 continues to provide clean, isolated and low-noise power while adding the ability to compensate for voltage drop.

Virtual reality pioneers and gamers alike can rest assured that their expensive accessories and peripherals will not encounter connectivity or power deficiency issues with the GIGABYTE USB DAC-UP 2. With Gaming Gear drawing large amounts of power and having firm specification requirements USB DAC-UP 2 is up for the challenge.

 

 

Immersive VR Gaming Experience

• VR requires more performance than Full HD graphics for a steady 90FPS or greater.
• Only Gaming PCs can provide the best VR experience.

 

Killer E2500 Gaming Network

 

Killer E2500 is a high-performance, adaptive gigabit Ethernet controller that offers better online gaming and media performance compared to standard solutions.

 

Give yourself the competitive edge: Optimize your network performance with the all-new killer Control Center

 

 

PCIe Gen3 x4 110mm M.2 (Up to 32 Gb/s)

 

GIGABYTE's M.2 solution offers considerably faster storage performance and support for both PCIe and SATA interfaces for M.2 SSD devices.

 

 

Fast USB 3.1 Gen 2 Solution

 

The latest USB 3.1 Gen 2 offers staggering 10Gb/s transfer speeds. 2x faster than USB 3.1 Gen 1 along with backwards compatibility with existing USB devices.

 

 

 

Turbo B-Clock

Built-in Advanced Performance Tuning IC

 

Turbo B-Clock Tuning IC in the AORUS X370 series 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 100MHz to 300MHz are now possible.

 

* Turbo B-Clock overclocking range may vary according to CPU capabilities.

 

Diagnostic LEDs

Hardware Troubleshooting at a Glance

Onboard LEDs controlled by the system BIOS indicate if a malfunction is occurring, allowing users to quickly diagnose which major component (CPU/DDR/VGA/HDD) is malfunctioning so they may take action promptly.

 

 

GIGABYTE Patented Double Locking Bracket

 

 

Dual Armor DIMM and PCIe Metal Shielding

 

Never worry about your heavy graphics card damaging your motherboard again. AORUS proprietary Ultra Durable PCIe Metal Shielding reinforces the PCIe connector to prevent slot damage due to heavy graphics card. The DIMM and PCIe metal shield also provides extra strength for when you forget to release the lock while replacing your component, adding a foolproof option which can save your PCs life.

 

Ultra Durable PCIe Armor

 

Enhanced Strength PCIe Design, Support for Heavy Graphics Cards For Extreme / VR Gaming Station

 

Ultra Durable Memory Armor

AORUS exclusive one piece stainless steel shielding design prevents against PCB distortion and twist, plate bending, in addition to preventing any possible ESD interference.

Anti-Sulfur Resistor Design

Sulfur compounds in the air can penetrate tiny onboard resistors creating chemical change and causing these resistors to open or short. If either of these occurs the motherboard will fail to function. By equipping resistors with an Anti-Sulfur Design GIGABYTE gives Ultra Durable Motherboards a whole new meaning.

Refreshed BIOS Easy, Smart, and Friendly

The BIOS is essential for users during initial setup to allow for the most optimal settings. With a new GUI and easier to use functionalities, GIGABYTE has been able to reinvent the BIOS to give users a better experience while setting up their new system.
