Gigabyte Z77X-UD3H Motherboard

Overclocking Options

The Gigabyte Z77X-UD3H has a few overclocking options. Below, we list the most important ones:

• Base clock: From 80 MHz to 133.33 MHz in 0.01 MHz increments
• CPU graphics clock: From 400 MHz to 3,200 MHz in 50 MHz increments
• CPU core voltage: From 0.800 V to 1.900 V in 0.005 V increments
• Integrated graphics processor (VAXG) voltage: From 0.800 V to 1.500 V in 0.005 V increments
• Memory controller (“IMC,” “System Agent,” VCCSA) voltage: From 0.715 V to 1.400 V in 0.005 V increments
• CPU VTT (“I/O”) voltage: From 0.800 V to 1.700 V in 0.005 V increments
• CPU PLL voltage: From 1.200 V to 2.200 V in 0.005 V increments
• Memory voltage: From 1.100 V to 2.100 V in 0.005 V increments
• Memory termination voltage: From 0.593 V to 1.934 V in 0.007 V increments
• Memory reference voltage: From 0.425 V to 1.385 V and from 0.593 V to 1.934 V, in 0.005 V increments
