BIOS and overclocking …
Let us continue with the BIOS / UEFI Setup options and the UEFI overclocking. By pressing F2 or Del during PC boot, you get access to the UEFI Setup.
The ASRock H170 Combo UEFI BIOS has a graphical interface that allows intuitive operation with the mouse or can still be conventionally operated with a keyboard.
In addition to basic information such as time, date, CPU temperature, motherboard temperature and fan speeds, you can see important details about the hardware. You also find an adjustment of the fans with one click.
In Advanced Mode at the first screen you can see the UEFI version, a language selection, the Easy Mode button and the My Favorite menu item, the CPU used, the installed DDR4 memory with dual channel support.
This My Favorite feature is very useful, because you can put here often-needed menu items by simply selecting the desired button, then press F5 and the feature is added to the my favorite overview page.
Of course, this H170 motherboard again has the selection to view the UEFI in Full HD and also offers the Active Page on Entry selection, where you can decide which UEFI page you want to see when you enter the UEFI Setup. You could just add all necessary points to the My Favorite overview and start directly to this My Favorite overview page. At the ASRock Fatality H170 Combo you find the Active Page on Entry option and the Full HD UEFI selection now in Advanced.
UEFI BIOS Update …
Before we begin with the UEFI settings, we first update the UEFI BIOS to the latest version.
To flash UEFI update ASRock offers some possibilities, eg the very simple Instant Flash ASRock Internet Flash or even with a direct connection to the Internet. The board is supplied with the BIOS P1.30. The time of testing the UEFI BIOS version P1.50 was available as latest download, which we updated of course immediately.
By the so-called ASRock Instant Flash option in the tool screen or via F6 during PC start you get into the ASRock Instant Flash utility. Or you can, as shown in the next image, go over the previously mentioned EZ Mode input side to Instant Flash.
Now you can simply flash a previously downloaded ASRock BIOS without a boot CD or similar by simply starting the ASRock Instant Flash utility. Just select the BIOS Flash ROM from the desired drive, such as a USB stick and even without a boot medium it is flashed and available after a restart.
In addition, there is also the OMG – Online Management Guard, with which you can define the times and days for the Internet access. This is for example useful for parents who like to specify a fixed Internet time for their children and want to block access with a password secure in UEFI BIOS, or for companies that allow Internet access for their employees only during lunch or after regular working hours.
ASRock H170 Combo overclocking …
In the H170 Combo UEFI setup, there are unfortunately only a few Intel LGA1151 overclocking settings.
So you can overclock the H170 combo motherboard not over the base clock – short BCLK, nor by the multi. So we could even not increase the CPU frequency of our Intel Skylake “K” CPU with unlocked multiplier by the CPU multiplier !
ASRock H170 Combo memory settings …
Higher clock rates are with the default BCLK frequency of 100 MHz not possible and a manual BCLK boost (see Intel OC guide) is unfortunately on the H170 chipset not yet (?) supported.
ASRock H170 Combo voltage settings …
Now we come to the voltage settings that can be adjusted in the UEFI.
To offer motherboard manufacturers a little more room for different motherboard types, the voltage regulator (FIVR) are now implemented externally on the motherboard and not anymore inside of the Intel Skylake CPU. Due to that the FIVR Configuration Menu is no longer available and we can proceed directly to the voltage configuration.
The motherboard has numerous voltage settings, such as the VCore with the Intel Core i5-6600K CPU Test from 0.900 to 1.520 volts (or offset), PCH +1.0 Voltage (chipset) from 0.900 to 1.300 volts, VCCIO Voltage Auto/High, VCCSA Voltage (System Agent voltage) Auto/High, DRAM Activating Power Supply from 2.400 to 2.800 Volt, Short Duration Power Limit, Long Duration Power Limit, Long Duration Maintained, the DDR4 voltage can be set in the BIOS from 1.200 volts to 1.800 volts, and if you use the internal graphics unit, you can select the GT Voltage from 0.900 to 1.520 Volt.
Overclock even easier …
Usually, there would be the Load Optimized CPU OC Settings at this point, but because the Intel H170 currently unfortunately unlocked no BCLK nor multi, we can left this part.
BIOS Undervolting …
The underclocking was also tested again in this review. Unfortunately you could not set a lower multi by the BIOS, even not with the Intel Core i5-6600 K CPU.
A tip if the USB keyboard and/or USB mouse does not work in Windows 7, because no driver has been installed: ASRock provides in the USB Configuration a PS/2 Simulator selection, which can easily be activated, and afterwards you can use the keyboard and mouse in Windows. Or with the Windows 7 USB Patcher to directly integrate the corresponding Intel USB 3.0 eXtensible host controller – short xHCI drivers in the Windows 7 ISO file.
Fan control …
The UEFI setup of passively cooled H170 Combo motherboard has an extensive, temperature-controlled fan controller for the 4-pin CPU Fan, CPU Fan 1 and 2, as well as the 4-pin Chassis Fans – Chassis Fan 1 to 3.
In the fan control you have the choice between Customize, Silent, Standard, Performance and Full Speed and in Customize mode several temperature steps are available, where you can assign a particular fan speed.
Because the fans are controlled with this fan control based on the CPU or the motherboard temperature, you can usually get along without an expensive fan control.
But that’s not enough, so ASRock has even implemented, as shown in the X99 reviews, a graphical interface for controlling the fan is integrated in the UEFI setup. You can find the FAN-Tastic Tuning menu also in the H/W monitor and thus can make all the settings very clearly. Simply select the respective fan connector on the left and you can select the mode – e.g. Performance on the right side.
Regarding the Chassis Fan connectors you can select which source you want to use for temperature measurement: Monitor CPU sensor or monitor motherboard sensor. Then just click Apply or exit the menu and save the values.
The fan control can also be conveniently set via the supplied ASRock Tuning tool. First, you start the fan test to determine all possible rotation speeds, and then you can adjust the temperature curve as desired. The ASRock A-Tuning software offers many other tools, such as temperature monitoring and some OC settings OC Tweaker menu.
Energy consumption …
