BIOS Functionality

Starting with the mainboard families based on the 7th series Intel chipsets, Gigabyte finally transitions to UEFI BIOS. Now, they use AMI code for their new “3D BIOS”, just like other mainboard makers, but their interface doesn’t look anything like the standard one we know so well already.

Here we see a layout of our mainboard, which can be flipped around for your convenience:

The key knots are highlighted in cycles. If you move the mouse pointer to the selected knot, contextual help info will pop up, explaining what this knot is responsible for and what parameters can be changed.

By clicking on the CPU socket or memory DIMM slot, you can access the “System Tuning” section that allows you to adjust the base clock speed, processor clock frequency multiplier, memory timings and frequency as well as some voltages. Note that in this case there will be an info pane on the right, which will display the current values of different parameters.

If you roll the mouse pointer over the heatsink of voltage regulator components, you can access “3D Power” section by simply clicking on either of them. The informational pane on the right will be different now, displaying a different set of parameters. If you don’t know what is displayed, use the mouse pointer to receive contextual help.

You can access the “UEFI DualBIOS” section by clicking the heatsink on the chipset:

By clicking the ports and connectors on the back panel you can get into the “Integrated Device Control” section:

If you click on the PCI Express slots, you will get access to a modest set of parameters in the “Expansion Slots” section.

And if you point at the SATA ports, you will access the “Drive Control Features” section, where you can select the desired drives mode, which is set at AHCI by default.

When I first saw the new “3D BIOS”, I thought that studying its functionality will be more of a game, something like pixel hunting, trying to find active zones. However, all the zones are pretty large, and are highlighted, so in reality you won’t need to hunt anything. The only not-so-obvious feature that I uncovered was the way to display the current CPU, base and memory frequencies by clicking the “3D BIOS” icon in the upper right corner of the screen.
