Settings to LIMIT CPU to avoid overheating=> throttling

[arielito]

Hi, i'm a very unfortunate owner of an HP-15f series; with a I7-1255U 12thgen CPU.

I use it for work so a lot of multitasking and videocalls

I've been going through a lot of problems with performance, that after changing thermalpaste, removing battery, changing chargers, and praying to the old gods; I arrived at the following conclusion (which might be wrong but it really looks like it)

Power boost is enabled => Temp runs high (over 60,65) => Throttling is enabled

and when throttling comes around, pc almost dies. calls are inaudible, the pc lags.

I've been tinkering with XTU and managed to avoid this at great length, but it kinda "loses" settings. I've found this app but I'm not an expert by any means; so I need advice on:

Which settings can i set, that avoids powerboosting, or thermal throttling at all costs?

I beleive i can work with the cpu "standard" specs, or I would rather have it running all time at 80% its capacity than going through 5 seconds at 120% and then 2 minutes at 30%

sorry if too long or repeated.

Post screenshots of ThrottleStop including the FIVR and TPL windows so I can see what options are available to you.

after changing thermal paste

What thermal paste did you use? Some popular thermal pastes like MX-4 should not be used in a laptop. They can quickly pump out within a week or two and CPU temperatures will be terrible after that. Try using Honeywell PTM-7950 next time you replace the thermal paste. It tends to last much longer.

XTU has always been flaky. Not sure why a big company like Intel cannot hire better programmers. I have not tested XTU in years. I used to see situations where the settings that XTU was claiming to be applying to the CPU were not being applied at all. ThrottleStop tends to be more consistent when applying its settings.

If the TPL power limit settings are not locked, you should be able to adjust the power limits so the CPU does not run like a top fuel funny car one second and a slug the next.

Thank you, here are the screenshots:

I use thermalright TF9

I would check the MMIO Lock box near the top right corner of the TPL window. Clear the Disable Controls check box. Try setting PL1 and PL2 to lower values. If 40W or 50W is overwhelming your cooling system then try setting PL1=15 and PL2=20. This will reduce maximum performance but it might allow your CPU to run at a reasonable speed and temperature without constantly bouncing back and forth between full speed and full throttling.

I do not know what values will be right for your computer. Try the values I recommended above. If this sacrifices too much performance then bump each value up 5W. Maybe that will be a better compromise.

On the main screen of ThrottleStop turn on the Log File option. Run a log file while you are using your computer so you have a record of your CPU performance. The log will show temperatures and any reasons for throttling. Attach a log file if you would like me to have a look at it for any problems. The log file will be in the ThrottleStop / Logs folder with today's date in its name.

Thank you very much for your help!

I will do just that and see what happens

one thing I've noticed yesterday, i was on a call and when they started listening me badly (i'm sure that's not good english, sorry) ; CPU Temp was on 50 which is cool

I'm starting to think there is something else wrong; but I'm certain temp is a factor. I'll keep going down this route anyw.

Thanks again!
