CPU automatically slows down once Throttle stop is activated
CPU automatically slows down once Throttle stop is activated
The issue started recently with frequent frame drops in the game. Usually it runs smoothly at around 80 FPS, but stability drops significantly. Checking Task Manager and ThrottleStop revealed lower temperatures and CPU clock speeds compared to normal levels. When ThrottleStop was active, the system cooled down to about 65°C instead of the usual 75-82°C. The CPU clock peaked near 1.4GHz, while the Turbo Ratio was limited to 22 versus a higher threshold of 2.2GHz.
Solutions tried included:
- Restarting Windows
- Applying System Restore
- Updating BIOS settings
- Resetting ThrottleStop to default and restarting
- Switching to a different version (ThrottleStop 9.2 instead of the current one)
The underclocking to 1.4GHz occurred specifically when ThrottleStop was running on the Asus A409JP model.
Hardware specs:
- Intel Core i5-1035G1 quad-core (8 threads) at 1GHz base with Turbo up to 3.6GHz
- Intel UHD Graphics G1 and Nvidia GeForce MX330 with 2GB GDDR5 VRAM
- RAM: 4GB DDR4-2666MHz + G.Skill Ripjaws DDR4-2666MHz (8GB total)
I adjusted the ThrottleStop and turbo settings back to their default, restarted my laptop, but it kept running at 1.2GHz to 1.4GHz (only when ThrottleStop was active). It stays hot, reaching up to 98°C even while using Discord, Steam, and Ms.Edge.
Even without games running, the temperatures remain excessively high for using apps like Discord, Steam and Ms.Edge. As mentioned earlier, it hits 98 C without any gaming activity, which is why I consistently enable ThrottleStop. The goal is to maintain lower temperatures while achieving a solid clock speed. This processor isn’t compatible with Intel XTU, so the only solution is to apply ThrottleStop.
Solved Disable the Fast Startup in BIOS makes the CPU run at usual clockspeed Don't know is this a driver problem / BIOS problem...
Ensure you have the correct setup for ThrottleStop and review the relevant logs. Share any screenshots or paste the log data here: http://www.pastebin.com. Address the cooling concerns by updating thermal paste or adjusting performance settings.
The issue seems unusual and occurs sporadically, often causing the system to slow down to a maximum of 1.4Ghz. Restarting or shutting down triggers the problem again. I usually hibernate the laptop, but recently it reappeared after a reboot following driver updates. Disabling Fast Boot helped before, though I've tried enabling and disabling it multiple times without success. After the ninth reboot, the clock speed returned to normal—lucky! For cooling concerns, I plan to replace my CPU with an Arctic Mx-4 next week. I've also slowed the CPU performance each time. I've attached screenshots of ThrottleStop settings and log files. Could you offer any advice to resolve this random underclock issue? Thank you! 2021-05-18.txt
Your log does not display any activity since you didn<|pad|> or when you ran it. Play a game for a minimum of 15 minutes to help identify the issue. Before testing, reset your turbo settings back to their standard numbers—36, 36, 33, 33 from top to bottom in the FIVR window. The log will indicate if your CPU is overheating and whether it’s throttling or experiencing other restrictions. In the Turbo Power Limits window, uncheck the box labeled Disable Power Limit Control. Ensure ThrottleStop isn’t blocking power limits. Verify the Speed Shift option so ThrottleStop can communicate with the CPU. If your CPU remains slow, open the Limit Reasons window and look for any red indicators. So far, no signs of low-speed stalls were found. Solving the problem will be challenging unless you provide data while it occurs. The main issue appears to be low turbo ratios, which some users report causing overheating in laptops. There are reports that this paste can cause rapid temperature spikes, especially in short periods. Performance may vary by laptop model. I’ve heard positive feedback about the Noctua NT-H2, noting its effectiveness in handling high temperatures typical for laptops.
