@nanook:
What we need explicit testing for is this: does the latest version of
the intel-microcode package which is present in the latest Ubuntu
(Cosmic Cuttlefish *or* up-to-date Bionic Beaver/18.04.01 LTS *or* up-
to-date Xenial LTS 16.04.01) disables overclocking on the i7-6850K ?
To test this, you need to install the intel-microcode package, and
reboot. Then, you check if overclocking is still active *while Ubuntu
is running* (overclocking will be working in UEFI/BIOS, regardless).
Removing the intel-microcode package and rebooting will undo all
changes, so this is a safe test.
Please report the contents of /proc/cpuinfo before you installed intel-
microcode, and after you installed intel-microcode *and rebooted to
activate it*.
Thank you!

Title:
intel-microcode when installed on an i7-6850k based system running
Artful breaks overclock
Status in intel-microcode package in Ubuntu:
New
Bug description:
I have an I7-6850k machine Asus X99-A motherboard, 128GB memory with
Artful 17.10 installed. The official clock speed of this processor is
3.6 Ghz, I have it clocked at 4.3 Ghz, however, if I install the
intel-microcode package, the machine ignores the BIOS settings and
reverts to 3.6 Ghz. Since this package is necessary from a security
perspective I'm stuck with either being insecure or losing an enormous
amount of performance.
