Tried multiple settings, when I go around -155V, the system crashes. Can anyone help me with the undervolting settings please, I want to play RDR2

Throttlestop hasn't been updated anymore?

The last beta update was on April 2nd, 2025 and I was wondering if the project has been abandoned

A little help

Started using throttle stop because my laptop heats a lot , I'm using a 2024 predator i7 13700hx with 4060 , during gaming it's gets to like 92-93c , I did not mess with too much , only set pl1/2 70/110 , and speed shift to 80 , what more can I do so that I can temps around 80-85 but not losing to much frames ,(I even cap fps around like 58 )

Any tips?

if we undervolt too much, what happens? Does the laptop crash and restart or what are the symptoms. I had some crashes, I don't know why but I have lowered undervolt a little. Any tips to prevent it

Any help is appreciated

I am having an MSI KATANA i use it a lot for coding so a lot of parallel cores running at the same time (specially when i do data science and i run programs using 5-10 parallel cores. Also i play occasional hearthstone.

Thank you so much. If any details please let me know. This image is while i do a lot of parallel work (a lot of parallel cores running)

Regarding i9 14900Hx Undervolt

I dont know much about Undervolting, Since i am a beginner. It my first time doing an undervolt.

At first i Undervolt In Bios And set it at Max applicable Undervolt that is -80mv. And tested system stability with test like Y cruncher and OCCT (CPU+RAM) And it was passed with 8 hour run. (cache Undervolt is 0 for both cache that is P and E)

But as i kept increasing And reached the point where my current undervolt is -150mv and P cache -100mv and Still is passing the test

(using ThrottleStop)

I confirmed that undervolting was working by watching readings in HWinfo application

Here are my core configuration

2p cores are at 55x

6p cores are at 52x

16e cores at stock 41x

Undervolt

E cache = 0

P cache = -100mv

Cpu core = -150mv

Passing OCCT And y-cruncher at this is frightening me

Ofc I havent played any games yet

If you have any games recommendations that could really test my Undervolt stability or Any rendering task will also do

OCCT setting were Extreme, Large data set with Variable load.

Is there any thing i should be concerned please let me know!!!

EDIT forgot to add PL values PL1 is 65W and PL for 2 mins is 90W Max PL values is 175W for CPU

14900hx Undervolting on Lenovo Legion Pro 7i

Short recording of Cinebench R23 Benching with my Current settings

Hello everyone, recently I've gone down the extensive rabbit hole of GPU and CPU optimizations. After much trial and error I was able to find good results. I am doing all of this on a pretty clean slate laptop that has been setup with a debloated image of Win11 from MicroWin. My general question is what I can do to push my results even further.

I am also running MSI Afterburner, 2480 @ 900mv, with 900 MHz memory clock on my RTX 4080.

I am running the following Throttle stop settings, I have not changed any TPL settings in TS:

I am running 38/16 efficiency core ratio and a 120 mv offset at 800mv for extra UV.

To find those values and settings I used a spreadsheet and tracked each point to find the sweet spot. My core issue is thermal throttling with p-core 0 when I push the thermal limits, it seems to be a preferred core. Here are the tables I made:

V/F point value

Question if i lets say undervolt to -145, does my v/f point need to be at least 10 points above it like 155 for stability or 160?

I can't automate the startup of ThrottleStop

Hi, here's my situation:

I have user A (the one I always use, which isn't an admin account) and user B (which is an admin account).

I don't know how to get ThrottleStop to start automatically when I'm logged in as user A. The only thing I've managed to do is get it to start as I'd like, but in user B. Or, I can get it to start in both A and B, but of course, it runs in the background, so I can't access it from the system tray (and I'd like it to).

And yes, I've tried several configurations in Task Schedule.

I'd appreciate any help. Thanks.

Can some1 tell me what those numbers mean?

Like in title. Undervolted cpu used benchmark and those numbers popped off after it finished. Is it good or bad?

Alienware x14 R1 (12700H) randomly stuck at ~1.7–1.9 GHz after reboot

I’m trying to figure out a really weird issue with my brother’s laptop that I cannot replicate on mine, even though our systems are basically identical.

Both laptops:

Alienware x14 R1

Intel Core i7-12700H

RTX 3060 (6GB)

16GB RAM

Same BIOS version

Same Windows version

Same cooling pad (same fan speed)

Same exact ThrottleStop (9.6) + power plan settings

Alienware Command Center has been cleanly uninstalled

The problem

After restarting, it’s basically a gamble:

Sometimes everything works normally (CPU boosts to ~3–4 GHz while gaming)

Other times, the CPU gets stuck at ~1.7–1.9 GHz and never boosts

This happens immediately after boot, before even launching games.

My laptop never has this problem. The clock speed may idle around 1.9GHz, but when I launch the game, it boosts up immediately. His on the other hand, if it were to launch or reboot on limp mode, it would just stay at 1.7–1.9 GHz forever, not moving even the slightest. Temps are basically ice cold so there's no way it's a thermal issue.

Our settings

Windows Power Plan (both laptops)

High Performance

Min processor state: 75%

Max processor state: 100%

Maximum processor freq: 2000 MHz

Maximum processor freq for processor Power Efficiency Class 1: 4200 MHz

System cooling: Active

Boost mode: Efficient Enabled

ThrottleStop (both laptops)

PL1: 50W

PL2: 55W

SpeedShift: ON (EPP = 0)

Everything else is unchecked.

At this point I’m pretty sure something outside ThrottleStop is clamping power, I just don’t know what. Any ideas would help a ton.

Can't find ThrottleStop 64 bit download

I Downloaded the latest version of ThrottleStop (9.7.3) (released April 2025) and the beta version

I have dell xps 16 9640 Intel Ultra 9 185H

There is only one ThrottleStop.exe file in the downloads

Both only run the 32 bit version

I need 64 bit

Please, how can I get the 64 bit version?

Any suggestions for settings?

I hope somebody will save me from this endless torture

First of all I am incredibly annoyed by this damn PL2 and PL1 handicap on this Acer Notebook. I have a custom cooling pad underneath that it can freezes the whole component up to the point where overheating isn't an issue anymore but this damn limit is just sucks.

I'm using an Acer Aspire 5 notebook with a pretty decent spec, i3 1115G4 and an MX350. TDP is 28watts max and 12watts low, base clock at 3ghz. Whenever the dGPU is on load, it will trigger this PL2 and then PL1 after a while which makes me stuck to 12watts reducing my FPS significantly. I tried everything like disabling DPTF, increasing PL1 and PL2 by also checking the lock box AND sync mmio, going to the BIOS and see if there's a setting to change PL limit result: none. For a record this doesn't happen before, it usually let it boost to at least 17watts (idk why it triggers PL2 locked on 17watt but it maintain the temp tho) for a consistent 3.6ghz while also maintaining GPU workload. It (CPU) can boost above 20watts when the GPU isnt on load. Here's the random part, sometimes the 12watts limitations is there sometimes it isnt last week. I'm fine with rebooting my laptop once to get that 17watts boost but then after another week, that 12watts suddenly never go away.

I know what I'm doing and I stumbled upon this article saying that I cannot do anything because it's the EC (embedded controller) that small cube thing sitting next to this damn processor is the one who overrides my CPU to not let it boost to what I wanted it to be. But idk, again temp is relatively too cool for this laptop which is a constant 60 degrees during heavy gaming load so temp isnt the problem here, thermal headroom is a LOT. I believe there are ways that I dont know off or might missed but please I hope someone in here can help me out, there's this one article where he managed to make the limitations off on his notebooks by doing a DDU on both igpu and nvidia, then reupdated it, I am not sure but i might give that a try later.
