ASRock Z77 Extreme4-M Motherboard

Overclocking Options

Below, we list the most important overclocking options available at the motherboard’s setup (1.30 BIOS):

• Base clock: From 95 MHz to 150 MHz in 0.1 MHz increments
• CPU voltage: From -0.300 V to +0.600 V in 0.005 V increments
• Integrated graphics processor (“IGPU,” VAXG) voltage: From -100 mV to +100 mV in 50 mV increments
• Memory controller (“System Agent,” VCCSA) voltage: From 0.925 V to 1.200 V in 0.092 V increments
• CPU VTT (“I/O”) voltage: From 0.768 V to 1.634 V in 0.009 V increments
• CPU PLL voltage: From 1.586 V to 2.349 V in 0.008 V increments
• Chipset (PCH) voltage: From 0.780 V to 1.646 V in 0.009 V increments
