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 MSI MEG Z590 ACE showed a good amount of headroom when overclocking. I was able to achieve 5.3 GHz at 1.38 V core voltage on my i9-10900K sample. For 11th Gen, I was able to get up to 5.2 GHz stable. Overclocking is largely limited by temperature because the Intel Core i9 processors will overpower any ambient cooling solution. Depending on settings, the system will either crash or severely drop frequency.
The MSI MEG Z590 ACE was great for memory overclocking as well, reaching 4000 MHz stable at XMP timings and voltages on my Trident Z Neo kit with both CPU samples. MSI has utilized their tabbed memory traces from the last generation to great effect.
