Just want to chime in here. I have this problem as well. I have had it on several motherboards, several CPUs, and every version of Ubuntu and Debian I have had. I am currently on Lubuntu 16.04 with kernel 4.4.0-78 and this issue persists.
My CPU has a stock speed of 3166MHz on a 1333MHz bus. If I set my bus to 1600MHz, which runs the CPU at 3800MHz, everything reports CPU speed correctly. However, if I run my bus speed anywhere in between 1333MHz and 1600MHz, the CPU speed is *not* correctly reported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/379873 Title: CPU Frequency Scaling Monitor reports incorrect CPU speeds when overclocked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/379873/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
