ASUS Crosshair V Formula Motherboard

Overclocking Options (Cont’d)

Below we list the main overclocking options available in the motherboard setup program (0404 BIOS). Pay attention to how you can configure the CPU voltages starting from zero volt. This is the first time we’ve seen such an option.

• CPU base clock: From 100 MHz to 600 MHz in
  1 MHz increments
• PCI Express clock: From 100 MHz to 150 MHz in 1 MHz increments
• CPU core (VDD) voltage: From 0.0000 V to 1.7500 V in 0.00625 V increments
• Memory controller (VDDNB) voltage: From 0.0000 V to 1.55000 V in 0.00625 V increments
• CPU PLL (VDDA) voltage: From 2.20000 V to 3.18750 V in 0.00625 V increments
• North bridge (NB) voltage: From 0.80000 V to 2.00000 V in 0.00625 V increments
• North bridge (NB) 1.8 V voltage: From 1.80200 V to 3.00775 V in 0.01325 V increments
• South bridge (SB) voltage: From 1.11300 V to 1.80200 V in 0.01325 V increments
• HyperTransport voltage: From 0.80000 V to 2.00000 V in 0.00625 V increments
• PCI Express voltage: From 1.11300 V to 2.00075 V in 0.01325 V increments
• Memory voltage: From 1.20000 V to 2.90000 V in 0.00625 V increments
• Memory bus (VDDR) voltage: From 1.20575 V to 1.80200 V in 0.01325 V increments
• Memory reference voltage: From 0.5900 V to 0.9750 V in 0.0625 V increments
