Gigabyte mainboards have one distinguishing feature: the basic BIOS functionality of flagship and low-end mainboards is hardly different. When you check out the BIOS of Gigabyte GA-P55M-UD4, you won’t have any reason to believe that it is a small microATX mainboard: everything is pretty “serious” here. We have already discussed in great detail the BIOS functionality of LGA1156 mainboards from Gigabyte in our Gigabyte GA-P55-UD6 review. You can find all BIOS screenshots without any exceptions in our Gigabyte GA-P55-UD3R review, but without the detailed comments of ours. So, this time we will quickly look through the major BIOS sections to refresh your memory a bit. I would like to remind you one more time that you must press Ctrl-F1 from the main menu of Gigabyte BIOS Setup in order to get full access to all available parameters and settings.
It is very convenient that the first on the list is “MB Intelligent Tweaker (M.I.T.)” section with the most important parameters for system overclocking and maximum performance optimization. However, the first screen only opens the list of available sub-sections for you and reports the basic system information.
You can set more details about the current system parameters in “M.I.T. Current Status” sub-section:
“Advanced Frequency Settings” sub-section will allow you to adjust frequencies, multipliers and dividers.
It is very convenient that the CPU related settings are all singled out on a separate page.
Almost all parameters are set to Auto that is why you should be careful when you change the operational settings significantly, like during overclocking, for instance. In this case the board may decide to enable or disable certain functions and technologies, which may cause some problems. It would be better to set the parameters to “Enabled” or “Disabled”.
“Advanced Memory Settings” sub-section allows fine tuning memory sub-system parameters.
Memory timings can be changed on a separate page. You can set memory timings for each channel individually or for both at the same time.
“Advanced Voltage Settings” sub-section offers options for voltage adjustment.
“PC Health Status” section doesn’t impress us with too many options or information. However, it is very nice to see that it retained Gigabyte’s ability to automatically adjust the rotation speed of four- as well as three-pin processor fans.
The only thing we should remind you of, is that you can launch Q-Flash utility for BIOS updating by pressing F8, and with F11 and F12 keys you can save and quickly load eight complete BIOS settings profiles. You can assign a memorable name of your own to each of these profiles, you can save each of them on an external storage medium. Moreover, the mainboard would automatically save a couple of last known good configurations, when the mainboard booted successfully.
Overall, the BIOS functionality of Gigabyte GA-P55M-UD4 is extremely good. The board has everything you might ever need, and even if there are certain drawbacks, they are uncritical and insignificant.
