ASUS ROG Maximux XII Extreme Wifi DDR4 Intel Motherboard

The ASUS ROG Maximus XII Extreme Wi-Fi is a flagship Extended ATX motherboard built on Intel's Z490 chipset, designed specifically for 10th Generation Intel Core, Pentium Gold, and Celeron processors using the LGA 1200 socket. It supports Intel Turbo Boost Technology 2.0 and Turbo Boost Max Technology 3.0, making it a compelling platform for enthusiasts who demand every ounce of CPU performance. At the heart of its performance story is ASUS OptiMem III, a proprietary memory trace layout that improves signal integrity and reduces noise, enabling compatibility with DDR4 kits running at 3600 MHz and beyond. With four DIMM slots supporting up to 128 GB of non-ECC unbuffered DDR4 memory — reaching up to 4800 MHz (O.C.) — the board is purpose-built for bandwidth-intensive workloads. Dual-channel memory architecture and XMP profile support complete the memory subsystem. Storage is equally well-served: four M.2 slots in total (two via the included ROG DIMM.2 module for drives up to 22110 length, plus two more from the Z490 chipset), eight SATA 6Gb/s ports, and RAID 0/1/5/10 support give builders tremendous flexibility. Intel Optane Memory readiness and Intel VROC support for M.2 drives further extend the platform's potential. Connectivity stands out with dual wired Ethernet — an Intel I225-V 2.5GbE port and a Marvell AQtion AQC107 10GbE port — eliminating network bottlenecks for LAN and online play alike. Wireless is handled by an Intel Wi-Fi 6 AX201 module (802.11a/b/g/n/ac/ax, 2x2, up to 2.4 Gbps max data rate, dual-band 2.4/5 GHz, OFDMA, MU-MIMO) paired with Bluetooth 5.1. For overclockers, the ROG Extreme OC kit includes an LN2 Mode jumper, Slow Mode switch, ProbeIt voltage measurement points, ReTry button, Safe Boot button, and a dedicated Start button — all accessible without powering down. The Extreme Engine Digi+ power delivery uses Infineon TDA21490 power stages, 10K Black Metallic capacitors, and MicroFine Alloy chokes for stable, efficient VRM operation under heavy loads. Audio is handled by ROG SupremeFX with the S1220A HD codec delivering 7.1 surround sound, 120 dB SNR stereo playback, 113 dB SNR recording, an ESS ES9023 DAC, RC4580 op-amp, LED-illuminated audio jacks, and an optical S/PDIF output. USB connectivity totals 22 ports across rear and front headers, including one USB 3.2 Gen 2x2 Type-C (20 Gbps), three USB 3.2 Gen 2, and six USB 3.2 Gen 1 ports at the rear I/O. The 2-inch LiveDash OLED display provides real-time system information at a glance.
