wow I can't finds the words to thank you man , I literarily was suffering from this problem and finally I found the solution here. By the way if your Turbo ratio limits is disabled like me, just downgrade your BIOS version and then restore BIOS setting to default.
My XPS 9560 was throttling that bad until cleaned the lint that was clogging the fans, and it ran 2.8 to 3.4ghz with the CPU and GPU running 100% with intermittent throttling. I then re-pasted the CPU and GPU and added thermal pads to the Voltage regulators, Ram and SSD, and the throttling disappeared, and it runs at turbo mode a lot more.
At the start of your video, Speed Shift was not enabled. If your BIOS does not enable Speed Shift, this needs to be enabled first in the TPL window. Later in the video it shows SST in green on the main screen. That is how you can tell if Speed Shift Technology is enabled or not. Once enabled, then you can adjust the Speed Shift EPP value. An EPP setting of 0 tells the CPU to run at full speed regardless of load. A good compromise for laptops is an EPP setting of 80. This allows the CPU to slow down when lightly loaded. Just click on the EPP number to the right of this setting on the main screen and you can edit it to whatever you like. Some users running on battery power like to sue an EPP setting of 192. To reduce the EDP OTHER throttling across all 3 domains, try increasing the PPO Current Limit in the TPL window. Thanks for letting everyone know how terrible the Dell XPS series runs as delivered from Dell. ThrottleStop is the only solution for many of Dell's miserable performing laptops.
Thanks for the advice! It's gotten worse though, the latest BIOS update has stopped reducing the turbo boost maximums, meaning you have to downgrade the BIOS first lol
@@plutotech3141 The BIOS update that disables Turbo Ratio adjustment also disables CPU voltage control. A one two punch to the gut. When you install a previous BIOS, you might have to go into the BIOS and select the Reset to Factory option.
The core and cache necessarily doesnt need to be the same though, Im running a -250 core and -140 cache on my XPS 15 7590 with the i5-9300h and its very stable, you could try the same but keep the cache lower.
Its interesting to see that on your 9550 the CPU with that undervolt of yours pulls 32 watts to maintain 3.1 ghz and with 82 degrees whereas if I clock my 9300h to 3.1 ghz with my undervolt it does 22 watts and with 50-55 degrees.
bro while playing games my cpu runs at 800Mhz so cant play games.....same config as yours should I use this setting? and how is your laptop doing with this setting?
It seemed to very much improve my performance across the board (not sure about gaming performance as I tended to use it for video editing and image editing work). I used it with that setting for a good while after this video, until I sold it fairly recently.
@@plutotech3141 Encroach? Having a piece of hardware run properly is now seen as encroaching on other products? Fkn capitalism 😂 what a joke. Sacrifice absolutely everything just to make a few more pennies. Totally stupid.

@@plutotech3141 can I know which BIOS version is best for doing this undervolting?
@@unkertech did you figure out it ?

That's what was recommended in a lot of the other tutorials, to keep those the same, so hence the recommendation in this video.

Hey man - I have a 9520 but have no idea how to set this up for my machine - where can I learn the knowledge of what to set at which value?
A lot of Googling, seeing other peoples setups, along with slowly decreasing the numbers via small intervals until it stops being stable.

Unfortunately the option 'Unlock Adjustable Voltage' is grayed out on my XPS 15 9550.
You need to change the settings in the bios. Can be done but it can be a long and tedious process.
@@dhareshmullappalli929 My bios is too new. They removed it with an upgrade.
Where is I can read about that?
Why doesn’t dell just ship these thermal turds undervolted from the factory. Just stupid.
Because they don't want it to encroach on their better specced more expensive machines? That'll probably be the reason.
