ASUS ROG Crosshair X670E Extreme DDR5 AMD Motherboard

The ASUS ROG Crosshair X670E Extreme is a flagship E-ATX motherboard built on the AMD X670 chipset, designed to deliver premium performance for AMD Ryzen 7000 Series processors on the AM5 platform. Its robust power delivery architecture, featuring dual 8-pin +12V CPU power connectors alongside a 24-pin main connector and a supplementary 6-pin PCIe power connector, ensures stable current delivery under demanding overclocking scenarios. Memory support is a standout strength. Four DDR5 DIMM slots accommodate up to 128 GB of dual-channel DDR5 memory, with validated speeds ranging from native 4800 MT/s up to 6400+ MT/s via XMP/EXPO overclocking profiles. Both ECC and non-ECC unbuffered configurations are supported, offering versatility for workstation and enthusiast builds alike. Expansion capability is equally comprehensive. Two PCIe 5.0 x16 slots operate in x16 or x8/x8 bifurcation modes for multi-GPU or NVMe add-in card configurations, while an additional PCIe 4.0 x4 slot rounds out expansion options. Storage connectivity is handled by six SATA 6 Gb/s ports. Connectivity at the rear panel is extensive: two USB4 Type-C ports driven by Intel JHL8540 controllers, one USB 3.2 Gen 2x2 Type-C port at 20 Gb/s, nine USB 3.2 Gen 2 ports (eight Type-A plus one Type-C), dual wired networking via Intel 2.5 Gb Ethernet and Marvell AQtion 10 Gb Ethernet, and an optical S/PDIF output. Audio is handled by the ROG SupremeFX subsystem with SupremeFX shielding, the ALC4080 codec delivering 7.1 surround-sound HD audio, and five LED-illuminated rear audio jacks. The source description references an ALC4082 codec with an ESS ES9218 quad DAC for front-panel output in marketing copy — this conflict with the spec table value of ALC4080 has been flagged for manual review. The board retains AM4 cooler mounting-hole compatibility, easing migration from previous-generation platforms. The E-ATX form factor measures 12 × 10.9 inches (305 × 277 mm).
