Digital VRM Design

The best VRM design ever built with the highest quality components.

• 12+1+1 Phases digital PWM + Low RDS(on) MOSFETs
• Support the latest CPUs, delivering enhanced system performance and ultimate hardware scalability.

Unlock DDR5

DDR5 Overclocking Up to 7600 and Beyond*

GIGABYTE is offering a tested and proven platform with an extreme memory performance boost.
* Memory overlocking and XMP profile support may vary depending on hardware configuration.
* Please see the complete validated memory support list. Product features may vary by model.

Shielded Memory Routing
All memory routing is under the PCB inner layer, which is shielded by a large ground layer to protect it from external interference.

Impedance Optimized Topology
By optimizing memory trace width, length, and style from HPC simulation to actual implementation, the overall impedance between the CPU memory controller and memory modules is lowered, achieving higher DDR5 speed.

Low Signal Loss PCB
Server-grade mid-loss or low-loss PCB material is chosen to lower signal loss inside the PCB and maintain DDR5's high-speed signal transmission.

Unlock DDR5 Voltage

GIGABYTE Exclusive DDR5 Circuit Design Increases DDR5 memory overclocking performance and capability by transforming Native DDR5 memory module to Overclocked DDR5 memory.

Secure Mode
The motherboard provides fixed 5V to Native DDR5 memory and built-in PMIC outputs locked 1.1v to memory IC.

• Unlocks Native DDR5 PMIC secure mode into programmable mode and controls Native DDR5 voltage with a wide range.
• Supports all PMIC vendors for maximum compatibility
* Memory overclocking capability will vary based on the user's hardware configuration 

Achieve Higher DDR5 Memory Frequencies with Ease

The DDR5 XMP Booster function provides optimized pre-defined profiles based on memory IC and PMIC vendor analysis for effortless performance enhancement and elimination of manual configuration for overclocked DDR5 memory kits.

* DDR5 MEMORY UPGRADE involves DDR5 memory overclocking; the overclocking capability depends on the user's hardware configuration.

Accelerate instantly
Boost memory performance instantly.

Automate input
No need to manually configure multiple memory parameters like clock, voltage, and timings.

Streamline overclocking
Easily overclock Native and XMP 3.0 DDR5 memory to higher frequencies.

Integrate database
Built-in database of pre-tuned profiles for different memory IC vendors.

Maximize DDR5 performance with your memory settings

XMP 3.0 User Profile empowers you to optimize your memory settings and achieve the best performance for your system.

SPD Re-defined or retrieved from the database
Users can define two empty SPD profiles and transfer them to another computer.

Performance Simulation
Simulate memory performance quickly by inputting clock and timing parameters.

Save/Load Profile
Save and load memory profiles for online sharing.

Boost non-overclockable DDR5 memory frequency
Increase the frequency of non-overclockable DDR5 memory.

One-click Clear Profile
Reset memory settings conveniently.

Thermal

Enlarged MOSFET Heatsink

3X Large Surface
Increased surface area up to 3X larger compared to traditional heatsinks. It improves heat dissipation from the MOSFETs.

Real One-piece Build
TMOS is a true single-piece heatsink. Compared to competitors ' multi-piece designs, its one-piece design and larger surface drastically improve cooling performance.

M.2 Thermal Guard

The M.2 Thermal Guard prevents throttling and bottlenecks from high-speed M.2 SSDs by helping to dissipate heat before it becomes an issue. 

6-Layer & 2X Copper PCB

2X copper PCBs design effectively lower the component temperature by its high thermal conductivity and low impedance.

High Current Support: Each fan header supports PWM and DC fans, a 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 curves.
Dual Curve Mode: Slope/Stair dual mode for different user scenarios.
Fan Stop: The fan can stop completely below the user's specified temperature point.

Smart Fan 6 BIOS UI

Enhance Fan Curve UI: This update enhances fan curve control with an expanded number of control points, from 5 to 7, and a larger fan speed graph, enabling users to have more precise and effortless control over fan curve settings.
Slope/Stair Dual Graph Mode: Switch between Slope and Stair modes to adapt to various user scenarios. Slope mode provides a linear fan speed curve, while Stair mode maintains a constant fan speed within specified temperature intervals.
Manual Input: For advanced users, manual input of fan speeds is available for fine-tuning and precise control over the cooling system.
EZ Tuning: You can simplify the process by setting 4 points on a rough temperature/fan speed scale. Smart Fan 6 will quickly generate a fan curve based on these points.
