The section with most of the overclocking-related settings is called “M.I.B.X.” (MB Intelligent BIOS X). There are two sub-sections that will allow configuring processor and memory parameters, while the majority of settings in the main window will deal raising the operational voltages. It is pretty convenient that we see the current voltages at the bottom of the window, but it is a real pity that we no longer can lower the voltage settings. For example, you can notice that the default memory voltage is 1.62 V. this is a safe, but nevertheless excessively high voltage for our specific memory modules, but we have no way of lowering it.
“CPU Overclocking Configuration” page will let you change the base clock, processor clock frequency multiplier and some other important parameters, which are highlighted green. The settings in white are unavailable to us, although this isn’t the case in the BIOS of other manufacturers’ mainboards.
All parameters in the “Chipset Overclocking Configuration” page dealing with the system memory are set automatically and cannot be changed. The board supports “XMP” profiles, but even in this case we cannot modify any parameters manually.
Even if we need to change only one setting, all of them must be set manually, which is not very convenient. Moreover, the bard doesn’t tell you the resulting memory frequency once all your changes have been applied, so you will have to calculate it on your own. However, this is not a big deal, since the “Memory Clock Multiplier” parameter doesn’t work. There is only one setting for it – 1.33, while in reality it equals 1.0. As a result, while the majority of other mainboards in the systems with Ivy Bridge processors offer us a wide variety of frequencies to choose from ranging between 800 and 3200 MHz, ECS Z77H2-A2X (v1.0) supports only seven memory frequency settings in the interval from 1067 to 2667 MHz.
The “Boot” section offers to configure the system behavior during startup.
You set user and administrator passwords in the “Security” section.
“Exit” section will help switch back to EZ Mode, save the configuration changes or abort them, or load the default settings.
You can save up to eight BIOS settings profiles in the “Profile Configuration” page. Each will be given a unique descriptive name. However, external storage media are not supported here.
In conclusion I would like to repeat once again that BIOS of Elitegroup mainboards has improved dramatically. However, there is still room for further positive changes bringing it closer to the best BIOS implementations out there from other developers.
