HP Probook 450 G8 power throttling

[Zawseh]

Hello all,

I have an issue with my HP Probook 450 G8, it is severely underperforming (about half the speed it should be getting in most tasks). I've already looked around and did some troubleshooting and figured out the CPU won't use more than 10 watts. It hovers around 1.0-1.4ghz and it never goes above 63c id also like to mention that it doesnt go above 40% usage. Thing is according to throttlestop it isnt throttling in anyway, I checked the BIOS and there wasnt any options to increase the max power limit of the CPU. Any advice? (The CPU is an i7 1165G7)

Thank you

@Zawseh -- do you have a "power" icon on the bottom-right of the computer's screen, to show when the computer is running on battery-power, and when it is running on electrical power?

If you click on that icon, do you see a "slider" that ranges from "maximize use of the battery" to "top performance"?  Is the slider currently set to 100% ?

Hello

if you click on the battery icon on system try, you can move the power slider left and right, to get maximum performance it should be at right.

which is the BIOS version of your HP Probook 450 G8 ?

did you try to run HP Image Assistant , in order to verfy all driver and BIOS are latest version ?

bye

Tried that didnt work sadly.

Thanks for the reply

Its maximized however the problem still exists still has a maximum cpu usage of 40% for some reason power plan is high performance when plugged in

@Zawseh -- is this your processor: Intel Core i71165G7 Processor 12M Cache up to 4.70 GHz with IPU Product Specifications

It has 4 cores and 8 threads, meaning that it is capable of simultaneously running 8 programs.

So, unless you have many apps that are open (Word, Excel, Adobe Reader, virus-scan, multiple Edge windows, and more) you probably are not "pushing" all 8 threads.  So, to get a "40% busy" rating means that the computer can do a lot more, if you throw more apps at it.

[Zawseh]

That is the correct processor, however (I dont want to seem rude) but thats not exactly how it works if the app has multithreading support then it can easily use all the threads (prime95 does and the torture test which was set to run on all 8 threads was only using 40% across all threads when viewed in task manager all threads were being used equally)

@Zawseh --  if the app has multithreading support then it can easily use all the threads

Yes, that is obviously true. So, do apps like Word / Excel / Adobe Reader exploit multi-threading? I doubt it.

How fast is your computer's RAM -- it might be the "bottle-neck" that is limiting the speed of the software.

In Task Manager, focus on the RAM -- actual transfer speed versus the manufacturer's listed specifications for the RAM.

This isnt a ram bottleneck its 3200mhz cl 16 which should be plenty fast

Thanks

@Zawseh -- This isn't a ram bottleneck its 3200 mhz cl 16 which should be plenty fast.

Hmm. I would think that the RAM is plenty fast for a dual-core system, or even a system with two cores and two threads per core.  But, when you upgrade to 4 cores, with a total of 8 threads, you could be hitting the limit of your RAM's speed.

Add more load onto your CPU, by simultaneously running www.SpeedTest.net in multiple browser-windows. It uses a good amount of CPU resources. It may "push" your CPU above that 40% level.

Add a few windows each showing a YouTube video, for more load.
