Finished Looks

Getting a closer look at the ASRock Z790 PG Sonic Edition, the blue undertone is strong here. The only actual RGB illumination is below the bottom M.2 sockets and heatsink. It is a missed opportunity from ASRock not to include RGB LEDs on the top half, considering the Sonic theme. For once, a motherboard that actually does not have enough built-in lighting, which goes against trend of rainbows dominating computers over the last 5+ years.

Test System

Supporting Hardware

Testing is performed with the newest available version of the BIOS at the time of review. All BIOS settings related to the CPU are left untouched. XMP is enabled for the memory. However, if the primary, secondary or tertiary memory timings are incorrectly set by the BIOS, it is tested as-is, to mimic a standard user. The same goes for the CPU. Unless it is a bug in the current BIOS—i.e., not present in other versions—any and all CPU boost parameters are left alone.
