11th gen I7-11800H undervolting

[eris31]

I usually get around 90-97 C when i start to play games, ive got a 3050 as well. Ive also unlocked the FIVR controls. Helping would mean alot to me since my laptop is overheating very often and i could honestly cook a sunny side up.

Have you ever cleaned out your laptop or replaced the thermal paste with Honeywell PTM 7950? Undervolting might not solve your overheating problem. The 11800H tends to run hot in most laptops due to inadequate heatsinks and fans.

Post a screenshot of the FIVR and TPL windows. Try undervolting the core and the cache to -50 mV for each. If that is stable, try -75 mV. All CPUs are unique so undervolting is all trial and error. No one has any magic settings that will be perfect for your 11800H.

Its been almost 2 years since i bought this laptop, i still havent replaced the thermal paste.

its an Acer Nitro AN515-57

My laptop blue screened after running the TS Bench for -50mV and for -75mV the laptop bluescreened immediately after applying the voltages.

thanks for the feedback, wouldn't even mess up with "bios unlock" for that <50 mV, pointless.

I have a Dell G15 5511 with an i7 11800H and RTX 3060. I was only able to undervolt by -50 mV on both Core and Cache, going any lower is stable on benchmarks but causes crashes and BSODs on some games. It looks like your CPU is not stable with -50 mV, maybe try -40 mV or -30 mV, although I don't think those values will lower temperature too much.

Other things you could try, use a laptop base with fans, this can reduce temperatures by a few degrees (around 5 degrees on average), or disable Hyperthreading, this can lower temperatures a bit or it can allow the CPU to clock higher at the same temperatures, this will reduce performance on heavily multithreaded applications that use more than 8 threads, but most applications and games will perform the same or slightly better due to higher clocks. Some game exceptions are Starfield, Cyberpunk 2077 and Uncharted Legacy of Thieves, those games like 16 threads.

Edit: Another thing you can try is undervolting the GPU using MSI Afterburner, this can lower the temperatures on the GPU, which in turn can lower the temperatures on the CPU, if they share the cooling solution of the laptop.

-40mV works fine for me altho it reduced about 5-10C it was really helpful, apart from that i also raised my the back of my laptop so that the fans could blow air out even more that also helped me reduce about 5C. My laptop now runs at around 70-80C no matter what i do, its only been few minutes since ive applied the voltages, ill let you know how it goes in the next couple of hours, thankyou! Also my GPU temps seems alright, it doesnt pass anything above 70C.

UV GPU in MSI AB isn't possible, at least with two ASUS TUF F15 (my 1st i5-10300H+1650 Mobile and current i7-11800H+3050 Mobile)

at first I thought disabling HT as it's (only) laptop in the end, but now I'm too envious - wtf I has had i5-10300H slouch with 8 threads total and now this i7 could be same "potato" with 8 threads lol? NEVER respected "pure" 6 or 8 cores Intels (we all remember the 4 core cpus without HT fiasco, doesn't we?).BTW, this monster even with disabled turbo allows me to play stable in most games (from "AAA" I play Hitman Assasination/or Hitman 3 it's the same) and no problems with GPU feeding.

I use passive DIY laptop stand which just raises it and it helps many. BTW am I only having stupid issues with Nvidia GPUs temp monitoring with MSI AB in ASUS TUF F15 laptops?! Both 1650 and 3050 don't fkin show their temps in MSI AB, need to see GPUZ lol

ok if even 30-40 mV helps then I'm in

Hello

I'll join the topic as I have the same processor, but with a 3070 graphics card. I've just applied the PTM7950 patch, and temperatures have dropped, so everything went smoothly.

Please suggest - in general, the system works stably with these settings, and I don't have any errors during TS Bench. However, I'm not sure how to set PL1/PL2 and whether to change anything in "Global Settings" (e.g. Power Limit 4). I'm looking for maximum performance and minimizing throttling.

PL1 - below 85, I get yellow warnings in PL1 in the "Limits" column for CORE and the FID clocks drop by about 0.7 (from 42.00 to around 41.30)
PL2 - nothing happens here, but I'm not sure if I should leave the value as is or increase/decrease it (I left it as it was when I set PL1 to 70)?

Cheers

below 85, I get yellow warnings in PL1

If you want to avoid yellow power limit warnings you can set both PL1 and PL2 to 90 or 100. Your temperatures are OK so a little extra power is not going to hurt anything. The power limits do not need to be set to some sort of perfect value. If the power limits are set high and the CPU gets too hot, it will thermal throttle to protect against any damage. Whether a CPU power limit throttles or occasionally needs to thermal throttle makes no real difference.

Intel says any temperature under 100°C is a safe operating temperature. Your computer is set to start thermal throttling at 95°C instead of the full 100°C so temperature wise, the CPU is extra safe.

Overall your settings look great.

I recently started setting Power Limit 4 to the max, 1023. I used to recommend setting this power limit to 0 but my laptop prefers a big number instead. For many Intel CPUs, whether you set Power Limit 4 to a value of 0 or set this to 1023 might not make any difference.

Check the Log File box on the main screen before playing a game. That makes it easier to check for any throttling issues after you are done testing or playing.

Hello again
I've changed RAM in my Laptop from 2x8 GB to 2x16GB (G.SKILL 3200mhz) and changed XMP profile to lower CL (currently 18 CL compared to 22 on old RAMs). In TS Bench I've got yellow THERMALS on CORE column on 960M test. I didn't change any TS settings from my previous post (except PL1/PL2 as suggested, but it was ok on old RAMs). Does upgrading RAM have impact on those thermals?

Any advices how to set correct settings with new RAMs?

 

[unclewebb]

If you increased the power limits then your CPU will run hotter and it might need to thermal throttle. Whether your computer power limit throttles or thermal throttles makes no difference. You can play around with the ThrottleStop settings but at the end of the day, you have a laptop with a powerful Intel CPU. It is going to run hot when run at full power.

Very few laptops have large enough heatsinks to run an 11800H at full speed and full power indefinitely. Most will reach max temperature and will need to thermal throttle at some point. The default turbo power limits will cause power limit throttling. Increasing those limits will cause thermal throttling. You can adjust the ThrottleStop settings however you like to try and balance the inevitable. Flip a coin. Power limit throttling and thermal throttling are both designed to lower the maximum CPU speed.

Go play some games and use your laptop with its new RAM. A little bit of throttling is OK.
