Overclocking
For Overclocking, I have kept the same procedures that I used for Intel's 10th generation. I have left the "Gear" setting on auto for memory overclocking. Every board tested so far has used "Gear 2" when pushing past the 3600 MHz XMP speed for my Trident Z Neo kit.
The ASRock Z590 Phantom Gaming Velocita was able to achieve 5.2 GHz at 1.38 V core voltage with my i9-10900K, and 5.3 GHz at the same voltage on my i9-11900K sample.
For memory overclocking, the ASRock Z590 Phantom Gaming Velocita proved about average, reaching 3900 MHz stable at XMP timings and voltages with my i9-10900K and 3800 MHz on my i9-11900K sample.
