The voltages may be not only increased, but also reduced below the nominal, which may come in very handy sometimes. For example, you may need it if your CPU is functioning at the lower than nominal frequencies or if you are using low-voltage memory modules.
The “PC Health Status” subsection reports current voltages, temperatures and fan speeds. The rotation speed of four fans out of five can be adjusted. You can adjust the rotation speed of the CPU fan and three system fans separately. You can select one of the two preset modes – Normal or Silent – or adjust fan settings manually to your liking. Only the rotation speed of the fourth system fan can be monitored but cannot be adjusted.
All adjustable fan connectors allow slowing down the fans even if they have a three-pin connector, because they finally brought back the “CPU Fan Control Mode” parameter. Now Gigabyte mainboards are again capable of adjusting the rotation speed of three-pin CPU fans. This feature was lost when they switched to AMI BIOS code, but is now back.
“Miscellaneous Settings” sub-section appeared and remained empty or disappeared completely from Gigabyte mainboard BIOS on several occasions. It turns out this is where you select the operational mode for your PCI Express 3.0/2.0 x16 slots.
The “System” section is similar to the “Standard CMOS Features” section of the older BIOS. It will tell you basic system information and show the list of connected drives on the “ATA Port Information” page. You can also change the date, time and interface language here.
The “BIOS Features” section is where you define your boot devices order, enable the startup picture, control other parameters and technologies, e.g. virtualization, and specify access passwords.
The “Peripherals” section is about external devices and additional onboard controllers. Chipset-specific technologies like Intel Rapid Start and Intel Smart Connect are also set up here.
”Power Management” section contains a conventional set of parameters pertaining to the mainboard power supply and start-up.
To apply or dismiss your changes you go to the “Save & Exit” section. Here you can also restore default settings. This section also offers you two parameters for BIOS settings profiles management.
You can save or load up to eight BIOS profiles, assign each of them a descriptive name. You can also save profiles to external media.
Some of the functional keys still work the same way. Just as before, F9 will bring up system information.
The built-in Q-Flash utility for BIOS updating can be launched by pressing the namesake button or the F8 hot key. It has become more convenient to work with and now shows you both the current BIOS version and the new one you are trying to update to. But it is still unable to work with NTFS disks and the current BIOS version is saved only in the root folder of a disk rather than where you choose to.
We weren’t too upset about some of the shortcomings uncovered in the very first version of the Gigabyte 3D BIOS, because we were certain that they would continue to enhance and expand its functionality. And we were absolutely right. They added the option to increase the processor Vcore by adding a specific value to the nominal setting in 3D Mode, even though this function doesn’t work on all the board just yet. The originally limited options for BIOS settings profiles management have been restored almost completely. It is again possible to adjust the rotation speed of three-pin processor fan. They came up with a very simple way of selecting the active mode. If you made all changes and saved them in 3D Mode, then you will be automatically sent to this mode when accessing the BIOS next time, if the last save was hit in Advanced Mode, then this is where you will get after system reboot. So, after improving and updating everything, the new Gigabyte 3D BIOS offers a full set of features for successful system configuring, fine-tuning and overclocking, so that there is hardly anything else you could possibly wish for at this time. And most likely we will soon see even more improvements, which we are very excited about already.
