First Looks: ASUS ROG Maximus IV Extreme (Intel P67 Express) Motherboard

We preview ASUS’ upcoming flagship motherboard for Intel’s new Sandy Bridge platform, the Republic of Gamers (ROG) Maximus IV Extreme. What juicy stuff does the M4E have to offer? Detailed close-ups and BIOS screenshots inside.

We first previewed the ASUS P8P67 Deluxe motherboard back in mid-November, and now VR-Zone.com has gotten its hands on ASUS’ upcoming flagship motherboard, the Republic of Gamers (ROG) Maximus IV Extreme! The Maximus IV Extreme is designed primarily with extreme overclocking and enthusiasts in mind.

All ROG motherboards have a very contrasty and eye-catching black and red theme. The Maximus IV Extreme has beefy heatsinks, and these should be more than sufficient to handle the heat output by motherboard components under extended usage and overclocking.


Like the P8P67 Deluxe, a pair of diagnostic LEDs provides POST codes. The Nuvoton NCT6776F Super I/O is located beside.

Under extreme overclocking where temperatures go way below zero, overclockers may find themselves struggling with the cold boot bug – the system does not POST until the CPU has warmed up sufficiently. The LN2 Mode switch helps overclockers to avoid such situations.

The board also provides measuring points for various voltages such as the CPU Vcore, Vdimm, and more.

Above the measuring points are PCI Express x16 lane switches. These switches enable or disable each of the four PCI Express x16 lanes on the board. The idea behind this is to allow enthusiasts to change GPU configurations without removing the graphics cards physically.


The Intel P67 Express chipset provides four SATA 3Gb/s ports (in black) and two SATA 6Gb/s ports (in red, beside the black ones). The two rightmost ports are also 6Gb/s capable, but are connected to a third-party Marvell 88SE9182 SATA controller.

The Intel P67 Express chipset sits under the large but flat heatsink behind.


The Maximum IV Extreme provides an inter-switchable dual BIOS design which allows the user to keep two different BIOS versions for different purposes. All the user has to do, is press the BIOS Switch button to toggle between the two BIOSes.


Along the bottom edge of the board, there is a 4-pin molex to deliver extra power to the graphics cards if you are running a multi-GPU configuration.

Towards the right, there are four USB 2.0 headers providing a total of eight USB ports directly from the Intel P67 Express chipset.
