Intel turbo boost operates for 20 seconds before reducing its frequency.
Hello everyone, I own a Xiaomi gaming laptop with an i7 8750h and GTX 1060. Recently, I applied some liquid metal thermal paste to the CPU. It feels much cooler now, but performance hasn’t improved—I’m still throttled every time. My Cinebench R20 score is 2317, while the average is 2497. The power draw stays around 70W at full TDP, and it drops to about 2.9GHz with 45W at around 20 seconds. I’ve tried everything in XTU and adjusted settings like throttling stop, undervolting, increasing TDP, boosting time, and adjusting ICCmax, but nothing changes. I suspect the issue might be locked by the ECU, and I’m not sure what else I can do. Despite that, I’m determined to keep testing and see if I can find a fix. Right now, I’m gaming at 2.9GHz with throttling, even though temperatures reach a maximum of 70°C.
The chip is hitting its power boundaries. Intel restricts these limits on certain chips, and you're observing a brief boost that switches between states. The motherboard may also block the MSR settings to safeguard the VRM. VRMs in laptops tend to struggle with excessive power.
You're hitting the power limit, cant do much about that since this is locked by the BIOS. Maybe you could get a hacked BIOS that raises it but that raises concern with other components as they may not be built to sustain over 45w of CPU power draw
Have you explored the ThrottleStop FIVR - Disable and Lock Turbo Power Limits option? I assisted a user with an 8750H yesterday, which removed power limit throttling on his Asus ROG GU501GM. https://www.techpowerup.com/forums/threa...-1.265754/ Some machines are fully restricted by the manufacturer while others remain unaffected.
The turbo settings were modified in ThrottleStop, the Disable feature was added, and it was verified. That means your laptop is now secured by Xiaomi. Previously, it wasn’t locked, but now it’s protected.
