Cpu downclocking issues

[Ovila3k]

Hi guys, so I have a problem where when my processor (7100U) is put under a heavy lead e.g. csgo, it downclocks to 380mhz from 2.4ghz. I know it's not thermal throttling as this has happened at only 50°C and this is confirmed by XTU. I have done a complete reinstall of Windows, messed around with power options and had the laptop plugged in and on battery.

Thanks in advance.

 

Full specs (not great):

Intel i3 7100U dual core quad thread 2.4GHz

GeForce 940mx

Standard other specs for a Lenovo ideapad laptop, all drivers installed as per Lenovo's website.

I have a similar laptop and played a lot of MHW on it this summer at 40+C ambient temperature and I didn't have any issues.  I use a laptop cooler however - a really cheap one  -  but it works.

 

If you get a laptop cooler *do not under any circumstances plug it into your laptop*  use an external power source (you have been warned) 

 

 

Also that is definitely not normal, I have an i5u and it never downclocks like that,  it pretty much always stays at base clock speed when throttling - which of course isn't enough to game on, hence the laptop cooler...  

 

 

Spoiler

*btw if anyone says you can't play MHW on a cheap ass Lenovo laptop - you definitely can 

*at 800x600 lowest settings possible

*always above 30fps,  usually around 50 during missions and such

Windows power management settings, set it to performance.

You should remove Intel XTU and try using ThrottleStop instead.  It includes features to help deal with some of the more common laptop throttling problems.

If you just did a clean install of Windows, you might need to install the Visual C++ 2013 run time libraries which are available from Microsoft.

You need to install both the x86 and x64 versions.

 

When you run ThrottleStop, click on the Limits button and see if anything is red when your CPU is throttling.  BD PROCHOT is the most common reason.  If you see this in red, try clearing the BD PROCHOT check box on the main ThrottleStop screen.

Lenovo also uses a few more throttling tricks.  Enabling Speed Shift in the TPL window and setting Speed Shift - EPP to 0 for maximum performance on the main screen might fix your problem too.  Post lots of ThrottleStop screenshots and I might be able to help solve this problem for you.
