- Support for Intel Core Ultra Series 2 processors with advanced power stages and enlarged VRM heatsinks ensuring stable performance
- AEMP III technology optimises DDR5 memory performance up to 8400MHz through two-stage clock driver and frequency tuning with an emphasis on stability
- Two M.2 slots with PCIe 5.0 support achieving transfer speeds of up to 128Gb/s and PCIe 4.0 with speeds of 64Gb/s for lightning-fast system and application loading
- WiFi 6E using the 6GHz band and Q-Antenna system ensures fast wireless connectivity, while a 20Gb/s USB Type-C port and 2.5Gb Ethernet provide high connectivity
- AI Advisor with a natural language interface, DIMM Fit Pro with up to twenty memory parameter settings, and Fan Xpert 2+ with automatic fan tuning simplify system management
- EZ PC DIY features, including a pre-mounted I/O shield, SafeSlot with metal reinforcement for PCIe slots, and the Q-Antenna quick-release, make PC building easier
Powerful delivery for maximum stability
The motherboard uses a 7+1+1+1 power stage configuration, where each stage integrates high-side and low-side MOSFETs into packages with a capacity of up to 80 amps. This robust design ensures optimal power delivery, efficiency, and stability for high-core-count Intel processors. The six-layer PCB design contributes to better stability and overclocking potential, while the proprietary eight-pin ProCool connector improves the connection to the power supply. The Digi+ VRM feature provides real-time voltage control, and the Power Saving mode lets you optimise consumption by adjusting the processor, lighting, and fans.
Advanced memory technology
ASUS Enhanced Memory Profile III technology is an advanced firmware feature that delivers peak performance with modern CUDIMM memory modules. Through two-phase comprehensive AEMP III tuning, it first optimises timing and then memory frequency, achieving the ideal balance between performance and stability even at frequencies of 7600 or higher. The DIMM Fit feature performs a precise analysis of individual memory modules to optimise performance and identify potential issues, while DIMM Fit Pro offers advanced users the ability to control up to twenty overclocking parameters, with options to define testing ranges and prioritise either stability or performance.

Choosing a motherboard
When choosing a motherboard, it's important to pay close attention to the socket type, form factor, and chipset. These are the most critical parameters that ensure compatibility between the board, processor, expansion cards, and other components. The specific socket determines your choice of processor, while the other connectors will dictate which components you'll need for your future computer.Specifications
