Question Cpu constantly overheat when turn on turbo boost

[dannish]

I'm using 2019 hp pavilion 15 gaming with i7 9750H and GTX 1650. The laptop always freeze and buzzing at the same time when heavy gaming and only figure recently that the cpu constantly overheat. Im using throttlestop to monitor the temp and it shows that its thermal throttling even when idle the thermal limit lights up sometimes. Tried undervolt, lower the turbo boost frequency, nothing happen until I disable the turbo boost the laptop now stable without any freeze and buzz. The fan is clean (speed cant be adjusted) , thermal paste already replaced this month. Honestly at this point I think turbo boost is just a gimmick. I still have to manually turn off turbo boost if I want to play games on the laptop.

What thermal paste did you use? Most popular thermal pastes will fail and start to pump out within the first couple of weeks. Order some Honeywell PTM 7950 and do the job properly. PTM 7950 does not have the short life span that many thermal pastes have when used on mobile CPUs.

Post a screenshot of the ThrottleStop FIVR window.

Ive send it to the service shop, knowing them they probably just use an average brand thermal paste.

Ive already defaulted the turbo frequency

@dannish
ThrottleStop shows that the maximum temperature of one core is 99°C and the core right beside it is only 76°C. Either the heatsink is not flat and not making equal contact with the CPU cores or the thermal paste is bad. You should not be seeing that big of a difference between individual core temperatures when the CPU cores are equally loaded.

The CPU cache offset voltage request is not being displayed in the FIVR monitoring table. If you run ThrottleStop when Windows VBS is enabled, you need to exit ThrottleStop, delete the ThrottleStop.INI configuration file and reboot. Post some updated FIVR screenshots after you do that. Running ThrottleStop with VBS enabled can corrupt the ThrottleStop.INI configuration file.

You can run msinfo to double check that virtualization is disabled. It is probably OK now. It was not OK when you were running ThrottleStop before.

Less voltage will help a little but you still need to replace the thermal paste. For maximum performance, the cooling needs to be perfect. The 9750H can put out a lot of heat. Many manufacturers used barely adequate heatsinks on these CPUs.

@uWebb429 done deleted the .INI config file and I've already disable virtualisation through BIOS since I've read your explaination in techpowerup forum before using the throttlestop. but for some reason the limit doesnt show thermal throttle anymore but the laptop definitely overheat when underload because the game freeze and buzz. the only times the thermal limit light up is when using TS bench only. before this, the thermal will light up if I didnt use any undervolt even when idle, but now even underload the thermal limit doesnt trigger.

Initially, I really want to use the PTM instead of normal thermal paste but decide to try the paste for last time to see if there is any difference. Ive already planned to replace it possibly in next couple of month, still surveying the PTM online.

because the game freeze

Your undervolt is working now. Most 9750H start to lose stability if the cache is set to any more than -120 mV. I would reduce both your core and cache undervolt settings until your computer is stable.

SAMyMAS on TechPowerUp decided to try PTM 7950 and he is getting much better results.
