Throttlestop undervolting doesn't seem to be working

Hello all.
I recently asked about some laptops I was looking at and landed on this one....

Dell G5 15 5590 - Intel Core Gen 9 i7-9750H Processor 2.6GHz (4.5ghz boost) 12mb cache, NVIDIA GeForce RTX 2060 6GB GDDR6, 16GB DDR4-2666 RAM, 512GB M.2 Solid State Drive, 15" 144hz refresh

Just want to say thanks for those who gave input it helped me make a choice, and I am more than happy with the performance of this thing, it has done above and beyond anything I had ever imagined.

I love the laptop but it has one issues, it gets dreadfully hot. This is a known issue with this model, so I decided to undervolt with throttlestop, but for some reason it doesn't seem to be working.

I am undervolted cpu core, cpu cache, and intel gpu all -125 mv offset voltage.

I run the TS Bench and it runs about 65-75 celc in temps max.

I decided to up the benchmark test and run prime95 as a benchmark to see what it does to the temps.
When I run prime95 my temps max out at 100 celc eventually and stay there. When I end prime95 my temps drop immediately to 55 then down to 35-40 celc avg.

I have recently formatted from a bad install of windows, but before this format I had throttlestop setup the same way and ran prime95 and my temps never went above 85 celc ever, even after a hour of running prime 95 the temps still maxed at 85 celc, yet now since the format and install I run prime95 and max out at 100 celc.

So it seems as if throttlestop isn't working at all for some reason. Is there some sort of setting I may have missed or need to set perhaps that anyone knows of?

At this point running at 100 celc there isn't really any reason to have throttlestop installed or use it at all if it's not going to work.

All I want to do is lower my temps....no overclock or anything.

 

I would start by running the benchmark with NO undervolt anywhere. Note your results.

Then run the benchmark again with -0.125mV undervolt. Note those results and compare to previous.

The 3rd factor of how the laptop used to run before the reformat is going to be hard to compare to given you can't put the system back in that state. You could have had a custom fan profile enabled, there may have been other 3rd party apps or control software from Dell.

All that said; ThrottleStop is just one step of the equation to lower temperatures. An even better course of action would be to repaste the CPU/GPU with better thermal paste than what Dell provides.

 

You may try to install Windows from Dell factory image. Did you install their software in your current Windows installation? Check in hwinfo if the voltage offset is applied properly.

 

Make sure you undervolt the CPU Core and Cache the same amount.

Prime95 can be considered by the CPU as a power virus and go wanky. Best is to use cinebench R20 in a loop to test thermal performance.

Thanks, I'll give that a shot.

Here is a pic of my settings I have, so it's all set good.....at least I think. It just doesn't seem like it's working at all.


As you see the temps have reached 100 celc, this was while playing cod:mw game for about 1/2 hour but it's as if there is no undervolting at all going on what so ever.......and the dell fan is on performance and I hear it kicking in, but it's as if nothing is doing a single bit of good, that or the reading within throttlestop are telling me the wrong thing.


Update:
I ran cinebench R20 and the same thing happens, I hit 100celc. It's almost as if TS isn't even activated at this point. Perhaps I have some setting I am missing.

 

You need to turn Throttlestop on, otherwise the program will monitor only.

On as in like green or red?

I was reading that right clicking it, hitting "turn on" is only for like cpu overclocking, not voltages......maybe I read it wrong perhaps.

If that's the case, how to I make it turn on automatically everytime the pc starts?


Just clicked ts and hit turn on via right click at the top and turn on (red icon not green).......ran cinebench again, and I still kick up to 99 - 100 celc

 

Check the guide I made and skip to the CPU Undervolting and overclocking part. The numbers shown are not for your computer and you will need to find what your computer can handle.

To have Throttlestop launch with windows, check this tutorial.

 

Ok I'm back.
I've tried everything aside from hardware modifications, ie: thermal paste, and still I hit 100c according to throttlestop.

I am not exactly the best when it comes to smaller things such as soldering, and such, so me attempting to redo the thermal paste may not result in such a good outcome.

My question and confusion is, why is throttlestop not working at all?
I am using it as many many numerous threads and posts and videos on youtube have suggested but I still hit 100c temps, so it's literally doing zero good and at this point.
Last time I noticed it was today when I started up cod:mw for a bit then checked my temps and the max shows quite a few 100c temps .

I'm open for ideas, as I am out of any and all ideas I have at this point.

@ Biker Gremling yours was the last one I tried, but it's not working.

I will add I have the folder under c:\ not anything like c:\program files or anything in case that may be an issue.


Update:
I moved the folder to c:\program files\throttlestop which didn't seem to have any improvement or effect on things. I still hit 100c sadly.

 

Get HWinfo64 to monitor. Check and see if the Core Offsets show any sort of change after undervolting. Don't forget to undervolt System Agent, as well. Match all 3, and you don't really need to undervolt the iGP.

 

It's like a microcode update that disables voltage tuning - Intel's solution to the "plundervolt" vulnerability:

And, success reverting back to the previous BIOS:

It's possible your's is a Windows Update patch of Intel microcode running at boot time, rather than the BIOS version. I don't have the Microsoft patch number, but perhaps you can see what got installed as an update after your fresh install and identify / remove it, reboot and verify it's fixed - also check your current BIOS version and see if Microsoft did you a "favor" and updated it for you to the plundervolt mitigated version.

Here's some more confirming info:
