My i5 8300h laptop CPU doesnt hit turbo boost speed

Recommended Posts

Posted · Original PosterOP

The problem occurred like a week or two ago, before that my CPU would sit on 3.88 ghz while gaming (turbo boost max speed is 3.99ghz). that time ago i reinstalled windows (version 2004) but i always try to use all the settings or tuning programs ive had before reinstalling windows on newly installed one, which i did but in clock speeds theres a big difference. while gaming turbo boost doesnt even hit 3.88 any time, first minutes of gaming it sits on 3.5-3.6 ghz and after like 5-8 minutes it gets stuck on 3.2 ghz and continues like this, so my fps is very inconsistent. so what might be causing this? ive tried lotta things and still no change. did new version windows bring any changes regarding turbo boost? idk, any help?

Turbo boost turning off is usually a sign of thermal throttling. What are your temps like?


Always remember the 80/80 rule of project management. That is, the first 80% of the project takes 80% of the time, and the last 20% of the project takes the other 80% of the time.

temps have always been bad but cpu has been maintaining  3.88ghz most of times anyways but something happened and turbo boost doesnt turn off, its base frequency is 2.3 ghz but clocks never go that down, it sits around 3.2ghz as i said so turbo boost works but not as good as its been working

What are your turbo boost power limits set to? These two limits control whether your CPU can use Intel Turbo Boost or not and how much boost to use. If the long term turbo power limit is set too low, your CPU will not be able to maintain its maximum speed. This is common with Intel's 6 core mobile CPUs but this is usually not a problem for their 4 core CPUs.

 

Run HWiNFO. It can tell you whether your CPU is getting too hot and thermal throttling or if it is power limit throttling. HWiNFO will also tell you if your CPU is using Speed Shift Technology. Look to see if the SST symbol is green.

The Speed Shift EPP variable controls your CPU speed. This might have changed after you installed Windows 10 2004. On some mobile devices, Windows can set the EPP variable to a value that can limit your CPU speed. Check for power limit throttling first.

HWiNFO shows SST in green so your laptop uses Speed Shift Technology. Windows 10 2004 might have made a change to the Speed Shift EPP variable which controls your CPU speed.

 

Open the HWiNFO Sensors window and check for any power limit or thermal throttling after or while gaming.
