When using the acpi-cpufreq driver, "/proc/cpuinfo" shows the frequency that is being asked for, not the frequency one actually gets. One has to use turbostat to know for sure.
For whatever reason, and as mentioned in my previous post, the posted turbostat output is saying that excessive power has caused the slow down. Both the CORE_PERF_LIMIT_REASONS and the IA32_PACKAGE_THERM_STATUS and all of the IA32_THERM_STATUS MSRs are saying this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1480349 Title: Intel Microcode Breaks frequency scaling in Xeon® E5-2687W v3 & E5-1650 v3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1480349/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
