I previously returned my G7 due to some hardware problems, though I didn’t really increase the clock speeds. Check the CPU settings for power management options. I increased the turboboost time limit fully and then set the turbopower maximum, which isn’t strictly needed because with the G7’s cooling system I found it better to just lower the voltage. You can tweak the turbo power up to around 5 to 10 watts higher based on how much you can safely undervolt the chip. The main focus is undervolting, which affects performance and heat. Starting small—perhaps -0.05v and adjusting gradually—is wise. I managed to bring it down to -0.175v before instability. Normally we raise voltage for faster clocks, but here we aim to reduce temperature and power use. This lets the CPU run at higher boosts longer, potentially reaching its full capacity under stress or even indefinitely. Let me know if you need more details. Cheers! Ooooo nice! Did you adjust anything? Edited July 2, 2018 by kevinisbeast707 Picture of xtu.
This approach worked well with the i5 8250u on an Acer Spin 5, delivering a comparable boost of around 28.6%. The standout achievement was pushing the multicore rating to 688 points. Not bad considering it's a budget mobile processor.
I reviewed the discussion and made some adjustments myself. I lowered the core voltage by 0.125 volts, which significantly reduced temperatures from 80-90°C to about 60-70°C. I also adjusted the turbo boost power limits—maximum boost power set to 90 watts and short boost power to 115 watts, ensuring stability before thermal throttling occurred. Lastly, I expanded the turbo boost time window up to a maximum of 96 seconds, which allowed me to maintain performance without any overheating issues. I managed to surpass your score by around 50 points, though it wasn’t a huge margin.
Great choice! It's smart to avoid pushing short-term settings too far, especially with those sudden temperature spikes. This approach lets you boost performance without risking overheating. The -0.125v adjustment is impressive—imagine what could happen with higher long-term power limits and a liquid cooler on the CPU.
Hey there, sorry for the delayed response—I've been juggling school and work. To clarify your question: the Turbo Short Power Max lets you control how much CPU power is used during turbo boost time, while the standard Turbo Boost Power Max adjusts the maximum power the CPU can draw over time. On devices like the 8250u, even without thermal throttling, the CPU might still slow down due to power throttling because it's trying to use more than what the Turbo Boost setting permits. This can occur with any laptop CPU. If you're not experiencing thermal throttling, consider lowering your CPU voltage a bit and slightly increasing the Turbo Short Power Max. You might see improvements around 200–300 MHz.
I recently discovered undervolting and followed the advice to reduce the laptop’s temperature. I adjusted the voltage settings on my G7 Core and cache, but initially thought I went too far. Games like Witcher III, Monster Hunter World, and even PUGB started crashing. After several attempts, we settled on -151.4 mV for the CPU core and cache. My typical 95°C temperature dropped significantly while playing high-end games, which was impressive!
You can try increasing the CPU's clock speed, but it depends on whether the chip is truly limited by voltage or if there are other restrictions in place.
It runs at speeds as high as 4.1 GHz. The exact mechanism isn’t clear, but lowering the voltage causes the CPU to run slower yet cooler.
