Verdict

The Asus Crosshair IV Formula is a high-performance Republic of Gamers (ROG) motherboard built on the AMD 890FX chipset and SB850 southbridge, featuring an AM3 socket that supports Phenom II, Athlon II, and Sempron processors with a TDP of up to 140W. This ATX board is designed for enthusiasts, offering four dual-channel DDR3 memory slots supporting up to 16GB at overclocked speeds of 2000MHz, three PCIe 2.0 x16 slots for multi-GPU CrossFireX configurations (running at x16/x16 or x16/x8/x8), and six native SATA 6Gb/s ports with RAID 0, 1, 5, and 10 support. Key pros include its robust 8+2 phase VRM design for extreme overclocking, integrated SupremeFX X-Fi 8-channel audio, and dedicated enthusiast tools like ROG Connect for remote tweaking and a physical Core Unlocker button. However, notable cons reported by users include a seventh legacy SATA 3Gb/s port that is perpendicular and awkward to use, a limited number of rear USB 2.0 ports (six) for heavy peripheral setups, and potential compatibility or thermal issues when attempting to run newer high-voltage FX-series processors on this older chipset.
