Had a perfectly working system using SMBIOS 14,2 with an i7 6700, Asus Z-170 A and 980Ti. Just swapped out the processor for an i7 7700k. I didn't change anything in Multibeast or Clover and the system appears to be working fine, but my CPU fan will speed up and slow down at odd times. Is this related to power management and, perhaps, the Sandy Bridge SSDT I have in the ACPI > Patched folder? I assumed I should change my SMBIOS to 18,3 and follow the Native CPU Power Management guide, but I'm getting a black screen after the Apple logo and the AGDPFix doesn't seem to reference 18,3. Any ideas?
