Windows 10: CPU not running at full speed even at high performance power mode Solved

    CPU not running at full speed even at high performance power mode


    I've notice that on windows 10 and 8.1, task manager would show the my max cpu core speed is 2.3-2.4 ghz. However, my Core 2 Quad q8400 is rated at 2.66 ghz. I tried changing the power settings in windows and try lowering my cpu temperature, but my speed would never reach 2.66 ghz.

    Should i be concerned about this or is it just a error on windows part? Also, i get different readings in Task Manager and CPU-z. Does anybody know a cpu benchmark that would allow me to compare my stock Q8400 to other Q8400s to see if it is on par?

    I wouldn't worry about this one bit. The PC will use the required amount of processor power when it's required. And you don't need to run the processor at full speed all of the time.

    thank but shouldn't my cpu be running at full speed especially for very demanding games? As you can see form the screenshots, my cpu doesn't go full speed when playing Witcher 3.

    Not really,, the PC is going to use the amount of speed that it needs at that moment.

    I get 2.66 ghz from both version of RealTemp. Does this mean that my task manager is not accurate in terms of the cpu ghz? Maybe it has to do with my outdated bios and how it wasn't intended for Windows 8+?

    If realtemp is saying your cpu is running at 2.66 then its fine , most likely your gpu isnt "man" enough to max out your cpu or your games are more gpu intensive
