Asus, my motherboard vendor flat out lies.

[Bug 1748543] Re: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock
@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*.

I am an overclocker with i7-6850k, specifically I have it on an Asus board with all six cores running at 4.3 Ghz and reliably at that. How do I obtain this particular micorocode to test? The last one caused the CPU to run at 3.6 Ghz with microcode installed so it is running without microcode form Linux and just what Asus supplies.

So, *as expected*, it was also going to trigger on Microsoft Windows.

Not sure why that would be as expected, Intel specifically sold the 'K' part to have unlocked multiplier.

[Bug 1748543] Re: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock
For the record: Now that Microsoft started distributing the recent batch of Intel microcode updates, there are reports everywhere from Windows 10 users, that the Microcode updates do break i7-6850K over-clocking. As expected, really. The recommended action is to demand a firmware update from the motherboard vendor, for motherboards that were sold with over-clocking as one of their key features. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748543 Title: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1748543/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I did get a recent BIOS upgrade from Asus, it now shows non-vulnerable for both variants of Spectre and for Meltdown with 3.13.0-33 kernel, so I'm good, don't know how this might impact folks with other motherboards. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

[Bug 1748543] Re: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock
(for the record: this bug should be set to "won't fix", as in "**can't** fix", but I don't have the required permission to set the "won't fix" state on the bug report). It might be fixed by Intel in a future microcode update, but unless someone tests this and tell us about it, we won't even know about it being fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748543 Title: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1748543/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1748543] Re: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock
Robert, you have a -K part, which officially "doesn't forbid" overclocking as far as I know, and this is the only reason I have not immediately closed this bug as invalid. It looks like now you get to find out if that means Intel *supports* overclocking or not on -K processors, instead of just passively not blocking it outright: start with ASUS support, it is possible that a properly updated BIOS/UEFI would still allow overclocking on the new microcode. For the record, updating the MSRs for overclocking *after* the microcode is loaded on the processor, as opposed to updating the microcode *after* the overclocking was done by the UEFI/BIOS *can* make all the difference. That means your BIOS/UEFI needs to have the latest microcode update (and you won't need the intel-microcode package). If ASUS can't help you, good luck contacting Intel about this... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1748543 Title: intel-microcode when installed on an i7-6850k based system running Artful breaks overclock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1748543/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
