Gigabyte Z77X-UD4H Motherboard

Overclocking Options

The Gigabyte Z77X-UD4H has voltage monitoring points, allowing you to monitor the chipset voltage (PCHIO), the memory termination voltage (DDRVTT), the memory voltage (VDIMM), the CPU PLL voltage (CPUPLL), the CPU VSA voltage, the CPU VTT voltage, and the CPU main voltage through a voltmeter. See Figure 10.

The portrayed motherboard has a few overclocking options. Below, we list the most important ones (F2f BIOS):

• Base clock: From 80.00 MHz to 133.33 MHz in 0.01 MHz increments
• CPU graphics clock: From 400 MHz to 3,200 MHz in 1 MHz increments
• CPU core voltage: From 0.800 V to 1.900 V in 0.005 V increments
• CPU graphics voltage: From +0.000 V to +0.350 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 controller (“IMC,” “System Agent,” VCCSA) voltage: From 0.715 V to 1.400 V in 0.005 V increments
• Memory voltage: From 1.100 V to 2.100 V in 0.005 V increments
• Memory reference voltage: From 0.695 V to 0.810 V in 0.005 V increments
• Memory termination voltage: From 0.593 V to 1.934
  V in 0.007 V increments
