>From reports elsewhere in the Internet, made by Microsoft Windows users with KB4100347 installed. Behavior in Linux might be slightly different.
* Several motherboard vendors affected (at least ASUS, EVGA); * Motherboards based on X99 with overclocking features available through vendor UEFI/BIOS; * RAM and uncore overclocking not affected by this issue (overclocked values are preserved); * CPU voltage not affected (changed voltage set points are preserved). Processors reported as affected: Intel 6800k, 5930k, 6900k, 6950x, Xeon (no data about xeon models, assume socket-compatible with X99 chipset). Reports imply the microcode update itself is the problem, not the updated microcode: Motherboards whose UEFI/BIOS already has the latest microcode revision are *not* affected by this issue, and overclock as expected. -- 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
