I also expect it will be re-enabled with subsequent major updates (at least) so anticipate doing this again (disabling Memory Integrity) after they drop. I'm sure it's an effective security setting for certain exploits so I guess you should only do this if you're comfortable of your internet security practices otherwise. So, thankfully it's fixable (sort of): either disable SVM in BIOS or disable Memory Integrity in Windows' Security settings. So when I started up after reverting I was happy to see boosting was back to normal. I thought it was an effect of my recently updated BIOS so I reverted to one that, as it would have it, did not enable SVM (CPU virtualization) by default. One is on an MSI B450 board but the other on an Asus so this effect, at least, isn't limited to MSI.

Although I could in HWInfo64, strangely enough, which is how I could tell core boosting was effectively disabled. And, as noted, monitoring was affected because I couldn't monitor CPU core clocks in MSI Afterburner.

Adding to also killed CPU core boosting on my 3700X and 5800X systems.
