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. Unfortunately, if you are using three-pin fans, only the rotation speed of the processor fan and of the first system case fan can be lowered manually, other fan connectors do not support speed adjustment for three-pin fans any more.
“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 and can therefore improve the performance in certain tests.
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 configured 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 again save profiles to external media and load profiles from them. Also, the profiles are saved automatically after each successful system startup.
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.
The software team, who have been working on Gigabyte 3D BIOS, have truly earned our absolute respect and praise. Within a relatively short period of time they managed to execute the transition from the old Award BIOS to the new AMI UEFI BIOS. Moreover, they managed to implement almost all the previously existing feature in the new BIOS. The profile management functionality that has been seriously limited in the beginning is now back in its most complete form including work with external media and automatic saving of the latest settings profiles after a successful system startup. It is now again possible to adjust the rotation speed of the three-pin processor fan. They came up with a simple and convenient way to select the active BIOS mode. If you were configuring your system in 3D Mode, this will be the mode you see next time you enter the BIOS Setup, and if your last settings save was in Advanced Mode, then you will get right back to it next time. As a result, after a number of improvements and enhancements the new Gigabyte 3D BIOS offers a full set of parameters for performance optimization, overclocking and simply comfortable overall user experience.
We only have one comment and one question left. We are definitely very glad that the ability to adjust the rotation speed of the three-pin processor back has been fully restored. However, back in the days all system fan connectors were capable of lowering the rotation speed of the three-pin fans connected to them. Now, this only works for the processor and the first system fan, while all other connectors can no longer do it. This was the comment. Now to the question: I wanted to ask about the new “Legacy BenchMark Enhancement”. If this parameter is so good at improving benchmark results, why hasn’t it been enabled by default? If it increases the speed in some situations, and decreases it in others, if it has some negative effects on performance, then we would love to know more about it. What exactly does it do and how does it work?
