CPU frequency = base frequency (usually 100mhz for Intel) x multiplier. If your CPU is running higher than 3.8ghz, either your base frequeny or multiplier (or both) have been changed.When you're seeing your CPU drop down to 3.4ghz, that's Intel's normal turbo behavior. In tasks that use fewer cores, the frequency can go higher, allowing more performance within the same maximum power envelope.i havent change base frequency and multiplier, it is 100mhz and multiplier is max ( x38 )when game uses 4 cores, then its max is 3,4ghz?when less then 4 cores, then it can go max 3,8ghz?

The modern PC sitting on your desk provides plenty of CPU power for web browsing, word processing and other common business tasks. However, there may be times when its processor power is maxed out, and needs help managing CPU usage. You can improve CPU performance and get more value from your computer.

CPU Power ExplainedYour computer’s CPU is its “number cruncher,” performing tasks such as mathematical calculations and comparing data. In most business applications, a modern CPU has it easy, loafing along at a few percent of its maximum. Two problems can bog down the CPU however: extreme amounts of math, or various non-CPU “logjams” that keep it from doing its job effectively. CPU Hogs: Media and MathScientific and statistical applications can tax a computer’s CPU resources, as can very large spreadsheets and databases. Other heavy uses include video and audio editing programs, including animation and rendering. If you’re considering “mining” cryptocurrencies such as Bitcoin, beware: the software will push your computer to its absolute limits. If you’re having CPU slowdowns but are not running the apps mentioned above, your computer needs fine-tuning.

Heat: Enemy of the CPUThe faster a CPU runs, the hotter it gets. To save energy, many modern computer CPUs automatically slow down to a fraction of their maximum speed when the temperature exceeds a preset limit. Have an experienced PC tech check your computer’s cooling system for dusty fans and clogged vents. If all is well, an add-on CPU cooling kit might help. System Cooling PolicyMicrosoft Windows 10 and earlier versions have energy-saving software that automatically slows your computer’s CPU down if its temperature rises past a set value.

You can alter your computer's Cooling Policy and Minimum Processor State settings to run the CPU cooling fans faster, which helps the processor run fast when needed. To change this setting in Windows 10, perform the following steps:. Click the Start button and click Control Panel. Click Power Options. Click Change Plan Settings. Click Advanced Power Settings. Expand the Processor Power Management list.

Expand Minimum Processor State List. Change the settings to 100 percent for 'Plugged in.'

. Expand System Cooling Policy List. Change the settings from Passive to Active for 'Plugged in.'

Slowdowns Due to Memory BottleneckSometimes, what appears to be a CPU slowdown is actually a memory bottleneck. A system running low on free RAM memory will spend most of its trying to “juggle” programs that barely fit. Meanwhile, the CPU waits idle.

If your computer is having performance problems due to “memory starvation,” you can free up memory by closing browser tabs, quitting idle apps; you can also add more memory. Overclocking: For Gearheads OnlyA practice called overclocking boosts the CPU by speeding up the computer’s master timing clock. Although this might work in some instances, you need to know what you’re doing. An overclocked CPU runs hotter, so it might need special cooling hardware. And with overclocking comes the risk of timing glitches in your computer, possibly crashing the system and losing data. Using Task ManagerNot sure what’s causing your CPU slowdowns? For tech-savvy users, the Task Manager is a program included with Windows 10 and earlier versions that reveals the state of your computer’s memory, CPU, drives and network in real time.

If one of your programs is consuming excess memory or CPU, Task Manager points out the culprit. To see Task Manager, press Ctrl+Shift+Esc.
