The CPU isn't reaching its full clock speed.
It seems my G17 keeps boosting steadily up to near its maximum limit. I believe Asus extended this range, possibly reaching around 20 seconds. I’m not sure if that affects longevity, but I’d probably file a warranty claim. Still, I think pushing it to full boost isn’t always the best approach—I’ve even reduced the CPU voltage, yet boosting continues, just with slightly lower temperatures.
During idle operation, the CPU remains active mostly in C7 mode with only a small fraction in C0. The voltage core stays consistent, resulting in minimal current draw and low power consumption. Under load or stress testing, the CPU stays in C0 continuously, leading to increased power draw and heat generation. This behavior justifies the implementation of power limits to manage thermal output. In stress scenarios, the CPU should maintain PL2 and lower its frequency accordingly, while turbo timing reduces voltage. Adjusting the Vcore affects only the clock speed, not frequency, and should be carefully controlled to avoid instability. Reducing the Vcore offset via undervolting doesn’t change the clock speed and can prevent issues if set too low. Boosting to maximum should only occur during idle, not under load, to preserve performance. Unless cooling is insufficient and temperatures rise easily, sticking to the recommended settings is ideal.
Verify the temperatures below full load. No new apps installed recently. Clean your laptop using canned air and consider a minor CPU undervolt adjustment.
