In this video, I walk you through the initial setup process and fine tuning of ThrottleStop to help reduce your laptop's running temperatures and speed the CPU up.
ThrottleStop is a handy tool to work around the thermal design power (TDP) limits in modern laptops. By reducing the voltage the CPU runs at (this is called undervolting), the CPU is able to stuff more frequency/cycles in a given power limit.
This video covers initial download, power profile setup, Speed Shift settings, and CPU undervolting itself. I also gathered statistics for benchmark runs and temperatures and present them in graphs for you to see.

Each CPU will have different ideal undervolt settings, so you'll have to experiment and iterate to find the best settings for yours. Not being able to undervolt your CPU as much as I was able to on mine isn't a bad thing, either! If anything, you can look at it as your CPU being closer to "optimal" than mine was out of the factory. :)

good video! thanks for the sharing.. I have T480 & have problem with battery 1 & battery 2 discharging order. Naturally I will want to discharge easier to remove battery 2 (external battery) which is removable & easy to replace without shutdown. The problem is, since **70 version of thinkpad (X270,T470..), they have changed the policy (low wear batt will discharge first). In my case it is internal batt (battery 1) which has low wear compare to batt 2. I research a little bit & found that lenovo change their policy about which batt to discharge first for powerbridged system & many user complain about that. But Lenovo seems not to care about the complaint. is this software able to set which battery to discharge first? thanks

Definitely my brother got more duration of battery life in his Thinkpad T480 Btw, we got minimum idle's of 1.4W with Windows 10, but then we have done a Windows 11 upgrade and now we see minimum idle's of 0.7W Seems that Windows 11 is more efficient than Windows 10 in terms of idle times. The specs of the laptops are: i7 8550U 8GB RAM DDR4 (Single-Channel) SSD 500GB SATA Nvidia MX150 Graphics 14'' 1366x768 HD Display PD: We saw that in ThrottleStop there is a Turbo limiter. We used it to set the CPU Turbo to 3.4GHz (Same as the i5 ver.) because the i7 has a max. Turbo of 4.0GHz D:

@ChezDoesStuff Год назад

That's great info! Folks often advice others to avoid the i7 because it supposedly ends up slower than the i5 once it thermal throttles, but looks like you fixed it by capping max. turbo. 0.7W idle is awesome, too!

I need serious help with undervolting. throttlestop doesn't undervolt on my t480. I have tried uninstalling wsl and stuff. The cpu is the i5-8350u vPro

@SceneArtisan Месяц назад

I'm looking at getting a Lenovo P50 and under-volting but all I know and feel comfortable with adjusting is to lower the voltage. I want to make sure my laptop (when I get it) doesn't get hot as the P50 is known to get very toasty. I want to under-volt it, but, yeah, in Linux even though I'm a complete newbie to Linux (I'll be using Linux Mint I think). Any advice, tips to keep things super simple and effective in lowering the under-load temps in Linux on the P50 would be appreciated. Thankies. :)

Hello. I'm not here for undervolting. I'm planning to get t580 next week and what can you say it's endurance? I am not planning to play games on it. Probably used for work like mails, sheets and lil bit of RU-vid. I'm planning to buy a 72wh battery. But in your opinion, is the t580 that power hungry? Or should I go for a t590 which is known for its endurance. Both are offered to me for 350 usd.

Great content, do these settings apply to a T480 with an i7 8650U and an MX150?

@ChezDoesStuff Год назад

I think it's worth exploring what specific settings actually run stable on your machine, since each chip is different. That said, folks have commented that vPro processors seem to be locked and incapable of undervolting. Please do report back what you find!

@one_step_sideways 4 месяца назад

@@ChezDoesStuff vPro processors are fully capable of undervolting. They are not locked, as I tried it on my other T480 with an i5-8350U (with vPro). I wrote a comment about how to enable undervolting on ThinkPads that support it - you may want to put a like, or maybe even pin it now.

@one_step_sideways 4 месяца назад

Try downgrading the BIOS as I described in my comment. You need to downgrade the BIOS to 1.34 on your T480s and also turn off Virtualization Based Security if it's enabled (if you use WSL2 or something like that).

You might want to consider: A. Pushing a pin into the power reset hole at the bottom B. Checking to see if there are thunderbolt/USB-C port driver updates pending C. Scaling cache back to -95 or -90 and testing (also test with TS disabled just to rule Windows system issues out) Hope this helps!

@aanfansub 10 месяцев назад

I think all of them are LOCKED by bios cause the plundervolt or whatever it calls. And everyone here think they are undervolting but they are doing nothing (the video is actually undervolting)

@one_step_sideways 8 месяцев назад

Indeed. On the updated BIOS versions it says that it's undervolted, but it's actually not. I use HWinfo to see if the undervolt is applied. Some people need to have their BIOS downgraded, if that's really only the BIOS that prevents undervolting, and not the new version of Intel ME. If it's Intel ME, then the laptop cannot be undervolted, which is a shame because I have the hot Intel i7-8550U with the MX150, and it could certainly use an undervolt to boost the multi-core performance.

@RayBlaxe Месяц назад

@@one_step_sideways what BIOS version did you recommend?

@one_step_sideways Месяц назад

@@RayBlaxe Actually as it turns out, even the lates BIOS on the ThinkPad T480 supports undervolting. But if you are having any problems, you might have to downgrade to the version 1.26. You are likely going to have problems with VBS being enabled rather than the BIOS, so make sure that VBS is disabled. With my i7-8550U I got -120mV on Core and Cache stable, and sometimes depending on the mood of the laptop, even -130mV is stable. With -130mV I got an increase from 3130 points to 3600 points in Cinebench R23 at 15W TDP locked. Worth noting that it's very close to Intel i7-1165G7, which came out on a 10nm node 3 years after i7-8550U, so undervolting has improved multi-core performance by 13%. That means that the T480 will have another year of staying relevant in the future compared to if it had no undervolting, which is great, because the T480 is the last great ThinkPad and we have to wait at least 3 years until T14 Gen 5 starts hitting the used market in droves.
