The Z370 HD3-OP is the first Intel Core i7+/i5+ enthusiast platform that supports built-in 32GB Intel Optane Memory. Optane fuels storage performance by acting as a cache drive giving users a significant boost compared to traditional mechanical drives.

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.

Fan Stop
Achieve fan silence. With Fan Stop map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking.

Hybrid Fan headers
Hybrid Fan Pin Headers. Assume complete control over your liquid cooling setup! Smart Fan 5 receives up-to-the-second information on flow-rate through the Hybrid Fan Pin Headers—giving you absolute mastery over your PC.
All Hybrid Fan Headers can automatically detect the type of cooling device whether it be fan or pump with different PWM or Voltage mode.

2-Way CrossFire™ Multi-Graphics
Multi-graphics configuration offers better graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.

Support for DDR4 XMP Up to 4000MHz and Beyond
GIGABYTE is offering a tested and proven platform that ensures proper compatibility with profiles up to 4000MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on GIGABYTE motherboard.

Supports RGB Light Strips in 7 Colors
Personalize your next PC rig to your liking by selecting the color of your choice to illuminate the external RGB light strip. A total of 7 colors are available to make your system appearance unique! LED Strips not included.

GIGABYTE Patented
DualBIOS™ Design. GIGABYTE Ultra Durable™ motherboards feature GIGABYTE DualBIOS™, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS™ means that your motherboard has both a ‘Main BIOS’ and a ‘Backup BIOS’, protecting users from BIOS failure due to virus, hardware malfunction, improper OC settings or power failure during the update process.

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 Z370 motherboards feature an audio noise guard that essentially separates the board’s sensitive analog audio components from potential noise pollution at the PCB level. LED trace path lighting Illuminates to show the separation of the PCB layers.
