Gigabyte 890FXA-UD7 Motherboard

Overclocking Options

This motherboard brings a feature called "Auto Unlock" that enables hidden cores of the CPU, if you are lucky to have a CPU with hidden cores (this function, therefore, won’t work with all CPUs).

The Gigabyte 890FXA-UD7 is clearly targeted to overclockers, providing a myriad of overclocking options. Below we list only the main ones available in the F1 BIOS.

• CPU base clock: From 200 MHz to 500 Hz in 1 MHz steps
• PCI Express clock: From 100 MHz to 150 MHz in 1 MHz steps
• CPU voltage (VDD): Offset from -0.600 V to +0.600 V in 0.025 V steps
• Memory controller voltage (VDDNB): Offset from -0.600 V to +0.600 V in 0.025 V steps
• CPU clock multiplier voltage (VDDA, a.k.a. PLL): From 2.220 V to 3.10 V in 0.020 V steps
• Memory voltage: From 1.210 V to 2.410 V in 0.020 V steps
• Memory termination voltage (VTT): From 0.720 V to 1.050 V in 0.025 V steps
• North bridge voltage: From 0.950 V to 1.450 V in 0.020 V steps
• HyperTransport voltage: From 1.100 V to 1.460 V in 0.020 V steps
• PCI Express voltage: From 1.500 V to 2.100 V in 0.020 V steps

Memory timings can also be tweaked.
