Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

Firmware

Like the other ASRock boards, the ITX Lightning starts in Easy Mode, which is primarily informative, but it lets you change a few options (XMP, profiles, boot order, Fan-Tastic Tuning, etc.). The black background and red accent colors match the Phantom Gaming theme and are easy to read. Advanced mode displays headings across the top, with details below.

Here, you can tweak everything that can be tweaked, as ASRock includes every option you can think of. Overclocking is easy, with most options on the same page, although some power options are in a different section. It’s a logical layout. The movement is smooth and easy to read. We have no significant complaints about the ASRock firmware.

Software

ASRock provides several different software options. It has the App Shop to install drivers and software, the Nahimic 3 audio control panel, the A-Tuning/PG-Tuning application that overclocks your system, control fans, the Polychrome RGB software, and more. There’s even a pop-up to install drivers when you first boot the system. ASRock’s software provides everything users need to manage and tweak their system.

Test System / Comparison Products

We’ve updated our test system to Windows 11 64-bit OS with all updates applied as of mid-October 2023. We kept the same Asus TUF RTX 3070 video card from our previous testing platforms but have updated the driver to the latest, keeping our games, F1 22 and Far Cry 6, the same. Unless otherwise noted, we use the latest non-beta motherboard BIOS available to the public using ‘optimized default’ settings except for the memory (XMP). The hardware and drivers we used are as follows:
