i7-7700k - Weird Speeds - HELP

Salkio · Sep 15, 2017

so my CPU is stock so boost clock is 4.5 Ghz and normal clock is 4.2 Ghz.
When my system is idle and i have Task Managed/Performance tab open my speeds are ranging from 1.2 Ghz to 4.8 Ghz and it randomly spikes. For example it goes from 4.2 to 4.5 to 4.07 to 3.70 to 3.02 to 1.2 etc etc etc. I have the Corsair H100i V2 and just replaced the thermal paste yesterday, temperatures also range and spike from 30C to 41 to 50 to 75 at times and it just keeps going. I have all my fans on 100% and my pump is set on performance. Im no expert but this does not seem good to me. Any recommendations you may have?

Hi and welcome to Tom's forum.

That behavior is totally normal since Intel (and AMD) have the option to optimize the energy and power consumption of the CPU when you are not use it at 100%.

In other words, the system manage the CPU clock and voltage that CPU runs and use depending of the task that you are running. If you are just checking you facebook your CPU will not run at 4.2GHz but if you are playing it is 99% that CPU runs at that speed.

Normal intel cpu has technology that when is not in use it will lower clock speeds.
The spikes are related to program such as antivirus, windows, looking for update, scan or else.
All normal.
For then temperatures, you are using a stock cooler on a know hot cpu.
If you want them down, you need a good aftermarket cooler such as cooler master hyper evo 212

It is normal to spike up when the cpu gets some activity.
That might be email send/receive, maintenance update search,
Indexing on a new build, ... etc.
