ASUS Crosshair III Formula Motherboard Review

The ASUS Crosshair III Formula

The ASUS Crosshair III Formula isn’t a new kid on the block but that hardly means it’s old news. This third version of ASUS’ top AMD motherboard is a vast departure from the previous versions in that it no longer uses an Nvidia chipset to provide SLI. ASUS has jumped on the Dragon platform train by using AMD’s 790FX chipset and providing two PCIe 2.0 x16 slots with CrossFire functionality. I have mixed feeling about this as I’d love to see SLI on a top-end AMD socket AM3 motherboard, but 790FX with SB750 brings so much goodness to the table that it is with only fleeting sadness that I unboxed this board. I’ve always enjoyed the Republic of Gamer products from ASUS and the Crosshair III Formula delivers on nearly all accounts.

The Crosshair III Formula essentially takes the 790FX M4A79T-Deluxe pcb and tweaks it a bit while adding additional features and bumping the quality in the components. Like all Republic of Gamer boards the Crosshair III Formula comes with an add-in audio module providing cleaner sound. There is also the LCD Poster which provides diagnostic information and a menu for browsing through the options provided in TweakIt. TweakIt is a hardware supported overclocking feature that lets you adjust all the BIOS settings on the fly. This can help all overclockers push their systems to the edge of stability. Before we dig into the board images and tests here’s a list of the features on the board.
