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

Our B850I Lightning started in the informative Easy Mode, but it allows you to adjust several options (XMP, profiles, boot order, access to Fan-Tastic Tuning, etc.). The black background with purple and blue highlights representing the Phantom Gaming theme is easy to read. The standard BIOS displays headings across the top, with subheadings and details below.

Software

ASRock offers several different software options. These include the App Shop, which allows users to install drivers and software, the Nahimic 3 audio control panel, the A-Tuning application, which enables users to overclock their systems and control fans, the Polychrome RGB software, and more. There’s also a Blazing OC Tuner and a pop-up to install drivers when the system first boots. ASRock’s software provides everything users need to manage and tweak their systems.

Test System / Comparison Products

We’ve updated our test system to Windows 11 (23H2) 64-bit OS with all updates applied as of late September 2024 (this includes the Branch Prediction Optimizations for AMD). Hardware-wise, we’ve updated the RAM kits (matching our Intel test system), cooling, storage, and video card. Unless otherwise noted, we use the latest non-beta motherboard BIOS available to the public. Thanks to Asus for providing the RTX 4080 TUF graphics card and Crucial for the 2TB T705 SSDs. The hardware we used is as follows:
