Unlock DDR5
DDR5 Overclocking Up to 7600 and Beyond*
GIGABYTE is offering a tested and proven platform with 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 shielded by a large ground layer to protect from external interference.
Impedance Optimized Topology
By optimizing memory trace width, length and style from HPC simulation to actual implementation, overall impedance is lowered between CPU memory controller and memory modules to achieve higher DDR5 speed.
Low Signal Loss PCB
Server grade mid-loss or low-loss PCB material is chosen to lower signal loss inside PCB and maintain DDR5 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
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 wide range.
• Supports all PMIC vendors for maximum compatibility
Memory overclocking capability will vary based on users' hardware configuration

Achieve Higher DDR5 Memory Frequencies with Ease
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.
