ASUS Maximus Formula Motherboard Review :: ASUS Maximus Formula BIOS and Overclocking

ASUS boards tend to use the American Megatrends AMIBIOS, and the Maximus Formula is no exception. The BIOS is broken up into Main, Extreme Tweaker, Advanced, Power, Boot, Tools and Exit. The Main Menu is where you get the System Time, Date, Legacy Diskette A, Language, SATA detection, SATA Configuration and System Information menus.

Extreme Tweaker is where the overclocking on the board is done. AI Overclock Tuner needs to be set to Level Up and you need to pick a CPU from the CPU Level Up list to overclock the CPU. The range of clock speeds and voltages are listed below in this handy dandy chart to show the BIOS limitations of the Maximus Formula board:


  • FSB Strap to North Bridge: Auto, 200MHz, 233MHz, 266MHz, 333MHz, 400MHz
  • DRAM Frequency, Auto, DDR2-667MHz, DDR2-800MHz, DDR2-835MHz, DDR2-887MHz, DDR2-1002MHz, DDR2-1066MHz, DDR2-1111MHz, DDR2-1335MHz
  • PCIE Frequency: 100-180MHz in 1MHz increments
  • FSB Frequency 200-800MHz in 1MHz increments
  • NB GTL Reference: Auto&0.49x, 0.51x, 0.53x, 0.56x, 0.57x, 0.60x, 0.63x, 0.67x
  • DDR2 Channel A Reference Voltage Auto &DDR2_REF+/-0 -30MV in +/- 10mv increments
  • CPU Voltage 1.10000V-2.40000V in 0.00625V increments
  • CPU PLL Voltage 1.50V-3.00Vin 0.02V increments
  • NB Voltage 1.25V-1.85V in 0.02V increments
  • DRAM Voltage 1.80V-3.40V in 0.02V increments
  • FSB Termination Voltage 1.20V-2.00V in 0.02V increments
  • SB Voltage 1.050V-1.225V in 0.025V increments

The E8500 Core 2 Duo CPU that I used for testing for an upcoming review was able to overclock the FSB to 467MHz up nearly 40% from the default 266MHz FSB of the CPU. This was done on air cooling, meaning that with a better cooling solution the CPU would have been able to be clocked higher. Other people have gotten the E8500 to 4.5GHz, but 4.4GHz is still an impressive overclock.
