Intel i7-9750h experiencing thermal throttling and undervolting problems.
Laptop: MSI GP65 Leopard 9SD
CPU: I7-9750h
BIOS version: E16U1IMS.101 (lowest version)
Hello community, I’m facing the same thermal throttling problem while gaming again. About a year ago I managed to fix it using throttlestop and undervolting the CPU. After taking a break from games and restarting, the issue persisted.
I attempted undervolting both in BIOS and through the throttlestop program. HWmonitor displays the values during both processes, but the system doesn’t show any performance improvement.
My actions so far:
- Reset BIOS
- Downgrade BIOS version
- Upgrade BIOS
- Enabled CPU overclocking in BIOS
- Performed undervolting in BIOS and throttlestop
I suspect a Windows reinstall might be the solution, but I don’t want to risk losing important files. Just a reminder that I successfully undervolted using throttlestop a year ago.
Hey there,
I believe anything above -250mv will be disregarded by the CPU regardless. I have the same CPU in my laptop at home, and once I return I’ll check my settings. It seems like your settings might be incorrect. I’ll get back to you with my configuration after 6pm. Do you know if there are any MSI-related applications that alter performance profiles, such as Max CPU performance? If yes, please uninstall them since they can affect TS settings. The same applies to Intel XTU.
Hey, thanks for your answer, but this isn't my undervolt settings. I just showed that i can go as far as the program lets. After a year ago my settings was about -150 on core and -60 on chase, and i got about 75-85 average temp. But now it seems that system doesn't react to any changes i make, doesn't matters if its -50 -200 or -1000. No difference i temps no difference in performance and no pc crash of too high undervolt. It doesn't matter if i undervolt in BIOS or in throttlestop.
Don't have other cpu performance programs only throttlestop
Thank you for the update.
It seems some makers restrict undervolting. I don't believe MSI falls into that category.
Have you attempted resetting the TS settings? Open the TS folder, remove the .ini file, move it outside the TS folder, then power off and restart. After that, restore the saved .ini back inside the TS folder. This might resolve the issue.
You could also completely delete the .ini file and start over from the beginning.
It's likely you're performing routine maintenance on heatsinks or fans. Also, think about replacing the thermal paste.
Take apart the CPU and give it a good rest, I recently bought an MSI GT60 laptop. Unfortunately, despite MSI's reputation, they made a big mistake with the thermal paste, which is now heavily commented on their forum. Even when using the turbo fan setting, the laptop would throttle down, but after removing the back cover and reapplying the CPU and GPU, it has worked fine since then.
On my HP Omen, the default PL1/PL2 were 90/90w. This is too high. Setting it high ensures no throttling. Usually I use 60/70. My CPU never exceeds 65w under any load, including Cinebench or heavy gaming. The only exception is with Prime95, which requires more than 70w. Did you reset TS as planned?
The note mentions that OP recently confirmed this action in his previous post.
You might want to consider a high-quality paste such as TG Kryo or Noctua NT H1. Both perform exceptionally well. I currently have the Noctua on my CPU/GPU temperatures at 4ghz, with all cores around 80-83c during a couple of hours of gaming on BF V. A good paste can really help.
I own a Dell G5 with the same CPU. Recent BIOS updates that the Dell software was configured to install automatically blocked undervolting. This was a reaction to a security vulnerability. I restored undervolting by reverting to an older BIOS and resetting all settings back to defaults. Even without performing the reset, it remained disabled. Additionally, I have turned off Dell updates.
