Asus Maximus Formula Special Edition X38 S775 Motherboard

As with all of Asus' most recent motherboards, the Maximus Formula is based around a BIOS from Phoenix Technologies. Some enthusiasts tend to favour the Award BIOS layout over Phoenix, but it's extremely hard to find fault with the overall wealth of features available on the Maximus
The "Extreme Tweaker" section of the BIOS is where you'll find most of the overclocking related options. Settings such as CPU multiplier, FSB/NB Strap, FSB Frequency, Memory Frequency, Memory Timings and Transaction Booster can all be adjusted in the upper section of this page.
Asus have also included a new feature called "CPU Level Up" on the Maximus. This essentially allows you to pick a new model of processor from the list and the BIOS will automatically adjust the frequency/multiplier settings to bring your existing processor up to the speed of the chosen one. This is certainly a good idea for people without previous overclocking experience, or those who are just after a quick bump in speed without getting their hands dirty.
The table below details the selections available from some of the more notable options on this section of the BIOS:
|CPU Multiplier||x6 upwards|
|FSB Frequency||200-800mhz (1mhz steps)|
|PCI-E Frequency||100-150mhz (1mhz steps)|
|CPU Voltage||1.1v-2.40v (0.00625v steps)|
|FSB Termination Voltage||1.20v-2.00v (0.02v steps)|
|Northbridge Voltage||1.25v-1.81v (0.02v steps)|
|DRAM Voltage||1.50-3.40v (0.02v steps)|
|Southbridge Voltage||1.050v-1.225v (0.025v steps)|
|PLL Voltage||1.05-3.00v (0.02v steps)|
With so many of these voltage options cleary being dangerous to the health of hardware, Asus have gone to the trouble of placing LED's at various points on the motherboard (CPU, Northbridge, Southbridge, DRAM Slots) that change from green to orange to red depending on how much voltage you are putting through the components.
Having such an extensive range of options available in the BIOS the last thing you wan't to do is lose your configuration once you've found the sweet spot for your overclock. This is where the Asus O.C Profile comes in to play. Allowing you to save all of your BIOS settings to one of two available profiles in the CMOS or to an external storage device, your settings can then be restored easily at a later date.
