BIOS and overclocking …
Let us continue with the BIOS / UEFI Setup options and the UEFI overclocking. After switching on the PC, press the Del or F2 key to access the UEFI setup.
The ASRock H470 Steel Legend UEFI BIOS has a graphical interface that allows intuitive operation with a mouse or can still be operated conventionally with a keyboard.
There is, as usual with the latest ASRock Intel motherboards, the ASRock EZ Mode – thus Easy Mode – which offers a clear entry page with many important information and still doesn’t look overloaded. To the basic information like time, date, CPU temperature, motherboard temperature, CPU voltage, first details about the hardware, fan speeds, hard disk population, RAID mode and fan settings with one click. New in the ASRock H470 Steel Legend is also the CPU temperature display as diagram.
Many other functions can be operated optionally by means of function keys, which can be called up with F1. For example, if you want to publish a screenshot in our PC Forum, you can save it on a USB stick with F12.
The System Browser view is no longer available on the ASRock H470 Steel Legend motherboard, but you will find again the Full HD UEFI selection and the Active Page on Entry selection, with which you can decide on which UEFI page you want to start in the UEFI setup. With the ASRock H470 Steel Legend you find the Active Page on Entry option and the Full HD UEFI selection under Advanced.
UEFI BIOS Update …
Before we start with UEFI overclocking, we update the UEFI BIOS to the latest version. Since ASRock regularly integrates new functions, better memory support and new processors, the BIOS update is recommended in most cases. For flashing the UEFI update ASRock offers several possibilities, e.g. the very simple Instant Flash or even the ASRock Internet Flash with a direct connection to the Internet. Via the so-called ASRock Instant Flash Option in the Tool Screen or via the F6 key when starting the PC you can access the ASRock Instant Flash Utility. You can simply install a previously downloaded ASRock BIOS without boot CD or similar by starting the ASRock Instant Flash Utility. Then select the BIOS Flash ROM from the desired drive, e.g. from a USB stick, which you have to unpack after downloading.
The My Favorite function is very helpful, because you can store frequently used menu items here, so that you can easily see them on a page and access them more quickly. You start with an empty page – by the way, it is unfortunately also emptied after a BIOS update.
The My Favorite page is now filled with your own menu items by simply going to the respective menu item, then pressing F5 and the desired functions are already included in the My Favorite overview page. Here you can see a selection of possible favourites.
On the tools page of this ASRock H470 Steel Legend motherboard is the ASRock Polychrome RGB LED entry, which is almost identical to the ASRock Polychrome RGB software, which we already mentioned on the previous page.
And you can set in the Polychrome RGB LED menu whether the LEDs should shine continuously, “breathe”, be controlled randomly or even to music. So the user has numerous possibilities how and how fast the LED stripes should light up. And if you don’t need the lighting, you can of course disable it completely.
Although ASRock does not offer an Easy Driver Installer option like on the B460 motherboard, ASRock makes the RAID driver installation very easy for the user by offering the Easy RAID Installer as an easy way to download the latest RAID drivers.
The handy SSD Secure Erase BIOS tool, which we first saw since the ASRock Z390 Phantom Gaming 9 motherboard, is also integrated.
Simply select the desired SSD and it will be deleted quickly and safely – for example, for secure deletion prior to SSD sale or in case of serious partitioning problems. Great thing, but use with care!
ASRock H470 Steel Legend Overclocking …
Now we come to the Intel LGA 1200 overclocking with the H470 chipset on the ASRock H470 Steel Legend motherboard. ASRock separates the OC-Tweaker menu of the ASRock H470 Steel Legend into CPU Configuration, DRAM Configuration and Voltage Configuration.
The view into the OC-Tweaker menu is at least much more pleasant than with the previously tested ASRock B460 Steel Legend motherboard. Nevertheless, even with an Intel “K” CPU with unlocked multiplier you wouldn’t have any setting options for the multiplier or the BCLK and this is unfortunately exactly what Intel wanted for the B460 and H470 in contrast to the Z490. So you can’t increase a multi on an Intel H470 motherboard and currently you can’t even raise the BCLK a bit to overclock the CPU. But there is the Boot Performance Mode setting for the speed during the boot process …
An Intel H470 motherboard is thus as badly overclockable as an Intel B460 motherboard, because even an Intel Core i9-10900K CPU can only be operated with the standard or turbo clock. If we discover possibilities for H470 overclocking, we will publish them as usual in the Intel OC Forum or directly with an OC tutorial in the PC Workshop.
ASRock BFB – Base Frequency Boost …
But wait, there was still something with BFB? That’s right! On the OC Tweaker entry page there is the so-called Base Frequency Boost option, with which you can overclock even a CPU with locked multiplier. You won’t get overclocking by multiplier, but you can adjust the powerlimit. Normally, the Core i5-10500 CPU is specified by Intel with a power limit of 65 watts. That means, if the turbo clock frequency requires more than 65W power limit over a certain period of time, this is prevented by Intel with the power limit throttling. We have already explained Intel Turbo Boost Short Power Max, Turbo Boost Power Max, Turbo Boost Power Time Window, Primary Plane Current Limit, Short Duration Power Limit, Long Duration Power Limit and similar power limits several times in our OC guides, because higher power limits play an important role in overclocking. Especially when it comes to maintaining higher clock rates over a longer period of time. ASRock now offers the Base Frequency Boost option in the OC Tweaker UEFI to raise this limit to keep the turbo clock frequency beyond the 65W power limit, more precisely up to 125W. Of course it is very helpful that ASRock has improved the VRMs on this H470 Steel Legend in contrast to the B460 Steel Legend.
We have done extensive tests with the ASRock Base Frequency Boost Option with Intel B460, Intel H470 and Intel Z490 in comparison and will shortly go into more detail about the overclocking possibilities and results, how much this type of BFB overclocking can achieve with a locked Intel Core i5-10600 CPU, or similar.

ASRock H470 Steel Legend voltage settings …
Now we come to the different voltage values that can be set in the BIOS. The ASRock H470 Steel Legend motherboard already provides clearly more voltage settings under Voltage Configuration than its B460 counterpart. It has e.g. the PCH Voltage, VCCSA Voltage, VCCIO Voltage, GT Voltage, and the DDR4 voltage can also be set in the Voltage menu, as we already showed on the second review page in the technical details.
With the CPU Core/Cache Voltage you can fortunately set offset and fixed mode again. On the Intel Core i5-10500 Test CPU the Fixed Mode could be set from 0.800 Volt to 1.520 Volt and the Vcore Offset from -0.100V to +0.300V.
ASRock H470 Steel Legend even easier overclocking …
For example, one could store undervolting values, balanced BIOS settings, office or gaming settings as undervolting, balance and gaming user profile to be able to quickly reload these values at any time.
BIOS Undervolting …
The downclocking or undervolting is also tested in this review. It was not possible to lower the Intel Core i7-8700K CPU frequency over the BIOS. You can lower the voltage to reduce the power consumption. Of course, underclocking is like overclocking outside of the manufacturers specification, so it is necessary to have some luck. ASRock gives several options for easy PC undervolting. There are many other UEFI settings to choose from, such as CPU Configuration, Chipset, Storage, Intel Thunderbolt, Super IO Configuration, ACPI Configuration, USB Configuration and Trusted Computing.
If you want to save power when using a PC with an Intel LGA1200 PC or if you use Intel Virtualization Technology to support multiple, simultaneous operating systems, you should also check the CPU Configuration menu under Advanced.
Fan control …
The UEFI Setup of the passive cooled H470 Steel Legend motherboard also features an extensive temperature controlled fan control. The settings for the fan controller can be found in H/W Monitor directly below the temperature and voltage display.
ASRock has also integrated the graphical user interface for controlling the fans in the UEFI setup. The FAN-Tastic Tuning menu item can also be found in the H/W monitor and can be used for all settings. Simply select the respective fan connector on the left side and then select the mode on the right side: Silent, Standard, Performance or Full Speed.
You can usually get along without an expensive Fan Controller, because the fans are controlled with this fan control based on CPU or motherboard temperature.
If everything is set, simply store the settings as usual with the F10 key and confirm with Z or on an English keyboard with Y. A new feature of ASRock is that all changes made are shown to the user before saving them – very practical!
