Gigabyte Z170X-UD5 Review


Gigabyte Z170X-UD5 Closer Look:

Gigabyte is using a UEFI BIOS implementation from AMI that features a pair of 128 Mbit chips that make up its DualBIOS technology. Not only do you get protection from a hosed up BIOS flash, but protection from malicious code that can be written into the BIOS. Flipping over to the backup BIOS will get you out of a jam. While not as flashy as some BIOS implementations, the Gigabyte UEFI BIOS is as straight forward as it gets.

M.I.T.: This section of the BIOS is where the overclocker will spend the majority of their time. All the clock speed, voltage, and DRAM tuning is accessed in this menu. Here there are six sub menus to choose from. Each has its uses. M.I.T Current Status lets you know the current state of affairs on the DRAM and CPU as far as clock speeds, temperatures, and the memory timings. Use this area for a quick checkup before digging further. Advanced Frequency settings is just what it says. In this section you can adjust the core frequency of the processor manually or by using some of the preset overclocking options. Functions that actually work. Advanced Memory Settings is where you can apply the XMP profile of your modules or tune them manually. There are sub menus for manually tuning the timings of the installed DRAM modules. Advanced Voltage Settings allows the user to tune the main voltage controls for the installed components. Loadline calibration is an either on or off proposition with Standard and High options for the CPU and on-die GPU.




Under the Advanced Voltage Settings are the options to manage the applied voltages to the motherboard and installed components. For the most part this is where you can spend a good deal of tuning time to pull the maximum performance for the lowest possible voltage. Options are for the processor, DRAM, chipset, and load line calibration. The options are straight forward and easy to find. One thing I noticed was that under the Advanced Power settings button, there were two options for load line calibration: one for the processor and one for the on-die graphics voltage. The options are standard and high.



System Information is a very basic page in the UEFI BIOS. You get information on the board model, current BIOS revision ( F4 in this case), date and time, preferred language, and the level of control you have. Like I said, basic, but necessary.


BIOS Features: In this tab you can adjust parameters specific to booting to the PC, such as the boot order, mode the BIOS boots into, Fast Boot options, Boot option ROMS, and more.



Peripherals & Chipset: This section allows the end user to manage much of the onboard hardware: SATA controllers, primary display output, USB, and LAN controller options. Under the Chipset tab, you can enable or disable the integrated graphics core, enable the audio controller, and control the InteL Z170 controlled Gigabit LAN.



Power Management is the section that lets the user manage how the Z170X-UD5 recovers from power off situations. The last section in the BIOS is Save and Exit. Of course this section is always last in line. In this section you usually get some of the more useful tools. For instance, saving overclocking profiles allows you to keep known good settings while you are overclocking. The one callout is that when you update the BIOS, the profiles are no longer valid. At the bottom left of the screen are a series of shortcuts. What should be one of the most useful is F8 for Gigabyte's Q-Flash utility. You will have to make sure your flash drive is formatted correctly to use this option to flash the BIOS.



Overall, this BIOS is easy to navigate through and is responsive to inputs from either a mouse or keyboard. The only real concern I had was trying to flash the BIOS using the same flash drive I have used for the rest of the Z170-based boards I have tested. After taking several shots at getting the Q-Flash utility to recognize the drive, I had to format it to either FAT16 or FAT32 for it to be recognized. Different, but eventually I was able to flash to a newer BIOS where this issue was corrected.
