X58 + Xeon X5675 needs SpeedStep off going from 12.2 to 12.3+

Hey thanks for reporting this. I'm running Sonoma now, but with AppleIntelCPUPowerManagement.kext and AppleIntelCPUPowerManagementClient.kext I'm locked to 1,9Ghz. Without them, just having ASPP-Override.kext loaded everything works

Thanks, interesting to know Sonoma doesn't need these anymore.

Well, I also didn't use them in Ventura having the same bahviour as in Sonoma. But again i have i7-960. Maybe it's different with your Xeons though
