i7-7700 don't run with Turbo Frequency

SuperMario · 22 Feb 2020 at 09:19

Hello together,

sorry for my bad english and if I maybe in the wrong forum. But I hope somebody of you can help me.

I have an Asus B250-Pro Motherboard running with an Intel i7-7700 processor and Windows 10 as OS. The processor should running in Turbo Mode with 4,2 GHz.
But everything I did, the highest freqency is only 4,05~4,07GHz. I have tried to change the energy plan to maximum, disabled the energy options in BIOS and disabled the intelppm driver. Everytime the same result.

Have anybody an idea how can I investigate the issue?

Thanks for your help
Mario

Thank you for your fast answer. But should I don't see this in the resource monitor? There is no once core who is running with the highest frequency.

Okay, I hope I understand you right. That means if I switch off HT one single core can run with 4,2GHz? My main issue is the game Assetto Corsa what is not programmed as multi-thread game (only read in Assetto forum). Does it make sense to change my processor setup in the BIOS to run as single CPU ?

Try running a load which uses only one thread (for example a single Prime95 worker). If you use logging like HWinfo, it will show that individual cores can go to 4.2.

You mean these both programs ?

This topic sounds exactly how my question. In that case the motherboard was the reason for the degradation.
