Fix: CPUs are not running at its full capacity in Windows 10 / 11

CPUs are designed to power your computer in such a way that it runs at its full capacity when there is a heavy load (like when you are playing a game) and it runs at a very low speed when there is no load or little load on your computer. If in your computer CPUs are not running at its full capacity subjected to a heavy processing task, then that is not a matter to neglect. This happens mainly as sometimes your CPUs on your computer are set at less than 100% in the Maximum Processor state option. Go for the fixes to solve the problem, but before moving ahead, don’t forget to run these initial workarounds.

Initial Workarounds-

1. Restart your computer and after rebooting, run a heavy task (like open a video game) check if the CPUs are running at full speed.
2. Check if you have any Windows Update pending on your computer. After updating your Windows check if your problem has solved or not.
3. Run a full scan on your system for malware, viruses. After scanning, reboot your computer and check if the CPUs are running at full speed.

If the problem is still there then go for the fixes-

  1. with fix 2 I also have the processor stuck at 2.3ghz… cant make my processor run over 2.8ghz in a heavy proyect of Studio One, an audio program that runs many plugins… I red somewhete that when windows runs too many but little programs (plugins) speedstep activates and limits processor to that speed (around 2.8ghz). Somehow I managed to run my proyect and reach 4.1ghz or so with throttlestop but worked just for a while, it seems windows detectet I was tryin to hack the system and blocked any tweak I could do to go above 3.0 ghz in that proyect… When the proyect is loading it goes up to 4.5ghz but when it finally loads, the speed goes inmediatly down to 2.8

  2. you should keep
    1-for maximum performance at all time(recommended by me).
    2-for maximum performance while saving battery.
    3-for maximum battery while moderate performance.
    4-to disable power management driver(not recommended by me).
    hope this will help:)

  3. Hi, its work for me at fix-2. value 4 the speed stuck at 2.30ghz (not lagging) and when i change to 1 the speed unstable but still not lag. shud i follow to value 4 or 1(curious) Thank You for your guide.

  4. Thank you. I was suffering with a very lagging problematic Toshiba Laptop without success even RAM & SSD changes avail , no benefit on it. When I discover that case all in a sudden I have had a very different fast, brand new unrecognizable laptop. One more thing to add, pls try to change power options either power or balanced opt will be better. Oddly enough my laptop gives best after shifting power to balanced op.
