    X99-E-10G-WS motherboard not boost all cores anymore with MCE

    On the latest and last BIOS. I haven't changed anything in the BIOS. Turbo = ON MCE = On Sync-All-Cores = 42. All cores used to boost to 42 when fully loaded. Verified with i7z.

    i7-6850K processor

    Now only four cores are listed working at 42 and the rest at 40. In reality under real load, only one core boosts to 40 and the rest stay at 38.

    Again, nothing was changed in the BIOS. So something changed in the OS. Ubuntu 16.04 kernel 4.15.0-20-generic. I have checked and the cpu_scaling governor is set to performance. The max freq is set to 4200 and the min freq is set to 4000. I have been reading all day long trying to determine what and when things changed in the OS that lost my all core MCE boost to 4200. Haven't found anything. Any suggestions on what has changed and how to revert back to all core boost?

    This is the output from i7z while loading all cores with Prime95.
