Laptop specs:

Processor: Intel(R) Core(TM) i9-14900HX
Video Card: NVIDIA GeForce RTX 4070 Laptop GPU
Video Card #2: Intel(R) UHD Graphics
Operating System: Windows 11
RAM: 32 GB


Laptop is so hot i cant keep my finger next to the power button, i have to always keep using a cooling pad, btw im not gaming or anything its just chrome opened and its so hot without using cooling pad and sometimes even when using cooling pad gets hot.


can anyone please help and tell me the best settings i can use in throttlestop ?


can anyone help me please, i would really appreciate it.
 
i tried this seetings


but each rune when i use like 10 min test always crash, here is bug report, only quick run that run fine.

here is the settings im using from the guide, what did i do wrong ?

10 min test always crash
When you undervolt a CPU and your computer crashes during Cinebench, that is a good sign that you have undervolted too much. A crash indicates your CPU needs more voltage to be stable. All CPUs are not identical. After finding a voltage value in a guide, you have to be prepared to adjust that voltage until your computer is 100% stable.

Start by switching to ThrottleStop 9.7.3

I do not bother undervolting the E cache setting in ThrottleStop. When adjusting the P core and P cache, consider leaving the E cache setting at +0.0000 until you find some voltage settings that are 100% stable in Cinebench and are stable in any game you play. Instead of -155 mV for the P core and the P cache, try using -145 mV and see if that is stable. Maybe -140 mV will work reliably and will allow Cinebench to complete without any errors.

The biggest problem I see is that your Lenovo Legion has inadequate cooling. Most laptops have this problem. A laptop needs to be able to dissipate at least 230 Watts of heat so it can try and cool a 14900HX running at its full rated speed during Cinebench. Your CPU is reaching 100°C when only running at 120 Watts. I am not familiar with your laptop model. That amount of cooling seems to be inadequate to achieve maximum performance. Having both PL1 and PL2 power limits set to 175 Watts does not make sense if your computer cannot cool 120 Watts.

For comparison, a well cooled and undervolted 14900HX can score over 38K during a Cinebench R23 test. Replacing the thermal paste is not going to solve your problem if the heatsink that Lenovo decided to use is inadequate.

still crashing, did i do something wrong?
if replacing thermal paste wont solve my problem, what do you recommend me to do ?
----------------------------------

results of 10 min test without crashing.

while running the test the  °C was changing lowest reached 69 max 78-79 but only like once you can say it was fixed between 72-73, is this good ?

------------------------------------

i tried another 10 min test with 145mv , crashed in the last seconds , this time °C was at +80.


when i start the test in ranking bar the orange bar will start at it highest then keeps going down and down, so i think the settings is not stable , right ?

Keep adding voltage until you find a voltage that allows Cinebench to complete without any errors. Try -125 mV for the P core and P cache.

what do you recommend me to do ?
If you bought a laptop that has a poorly designed cooling system, you will have to keep reducing performance.

Turn on the ThrottleStop Log File option so you have a record of your CPU performance when testing. Exit ThrottleStop when finished testing and attach a log file to your next post. It will be in your ThrottleStop / Logs folder with today's date in its name.

Do not set Power Limit 4 to 125. Set that to at least 246 or whatever it was originally set to. I prefer setting Power Limit 4 to the max, 1023. I also like to set IccMax to the max, 511.75 for the CPU Core, P Cache, Intel GPU and iGPU Unslice. Setting any of these current limits too low can cause instability.

well first i tried again with 140mv but crashed even though before i did run with same settings without crashing.

the results in screenshot using 125 mv.

btw im using balance mode , should i keep using balance mode or switch to Performance?

When you run a test and sometimes it works and sometimes it crashes, that means you are getting very close to how much voltage your CPU needs to be stable. I would use -125 mV for a few days to see if you have 100% stability. If that proves to be OK, try -130 mV for a few days.

switch to Performance
I prefer to use the Windows High Performance power plan. This keeps my CPU pegged at a steady 5200 MHz whether lightly loaded or fully loaded. I have set all of the turbo groups to 52. One reason I do this is to avoid the high voltages that get fed to the CPU when it is allowed to run at its default maximum speed when lightly loaded. Limiting the maximum CPU speed results in less light load performance. It is a compromise. Less max speed equals less voltage which should keep the CPU healthy for longer.

The start of your log file shows VMAX warnings. That indicates the CPU is being throttled because the VID voltage has reached the maximum safe amount. That is why I am still using an old microcode version, 0x116. The latest microcode versions that you are using might be increasing the default voltage. This trick can improve stability but whether the CPU will continue to run reliably long term is debatable.

Your screenshot shows that you are trying to use both ThrottleStop and your Lenovo software to manage the CPU power limits. If you are going to use the Lenovo power management software than I would suggest not using ThrottleStop to manage the turbo power limits. Check the Disable Controls box in the TPL window to tell ThrottleStop to leave the power limits alone.

Your testing shows that the Lenovo software is reducing the MMIO PL1 turbo power limit down to 85 Watts and then it drops it further down to 70 Watts. That reduces maximum performance. If you want ThrottleStop to try and manage this then either try checking the MMIO Lock box or try checking the Sync MMIO box. I do not have a Lenovo laptop so I do not know what will work best. If you use the Lock option and later change your mind, you will need to clear the MMIO Lock box, save that setting and reboot to unlock the MMIO power limits.

i think i dont have Lenovo power management software.

i tried another 10 min run with Sync MMIO checked and this is the results but temperature was high. the laptop was so hot

i dont have Lenovo power management software
Some software on your computer is changing the MMIO power limits. When Sync MMIO is not checked, the MMIO PL1 power limit is dropping down to 70 Watts. ThrottleStop is not doing that. There must be some software from Lenovo running on your computer that is doing that.

temperature was high. the laptop was so hot
You bought a laptop that has Intel's most powerful mobile CPU. A 14900HX with a small and inadequate heatsink is going to run very hot during a full load Cinebench test. Temperatures over 90°C are normal and within the Intel spec. If you do not like seeing such high temperatures then use ThrottleStop to lower the turbo power limits. This will reduce how much heat your computer is putting out. It will also reduce maximum performance.

Ive been trying some settings and doing tests with timer off on cinebench, this time i dont get cinebench crashes the laptop shutdown automatically, this is not normal, right ?
 
Ive been trying some settings
I do not know what settings you were trying or why your laptop shutdown. A properly engineered and functioning laptop should be able to run Cinebench without ever shutting down.

If you are using ThrottleStop to increase the MMIO PL1 turbo power limit then maybe your laptop is not happy with that setting. The default 70W limit that your laptop is trying to use is not great for performance.
 
I'd:
1. disable HT if it's possible in BIOS, or, in radical and possible variant - disable turbo. Considering IPC and core count the "bottleneck" won't be "so bad", heck, I've done it on my i7-11800H which is way older and slower and no problems - INSTANT TEMP DROP!
2. Lower GPU PL with MSI Afterburner.

i was just following some of the settings in the "Valour549 Ultimate Throttlestop Guide", thats was causing my laptop to shutdown.
i thought i found stable settings until i tried 30 min test but cinebench error appeared when test was about to be done. in the screenshots you can see the settings i was trying.

last night i tried god of war with ultra settings, laptop was so hot.

is this going to work for same processor ?
2. thank you for suggesting this , i will try it.
