Conclusion

Undervolting is, as our tests prove, an excellent way of lowering the temperatures in a laptop. And because we’ve lowered the temperature of the CPU, other components will be a lot cooler because they aren’t affected as much by the heat from the CPU. You get a cooler system with longer battery time and if it is performed correctly, you won’t suffer any stability problems.
You can, as we’ve shown, also set different clock frequencies that the computer can “throttle” between. I not only use the factory defaults of 800 MHz and 1600 MHz, but have also added a middle-clock frequency of 1200 MHz. I can use this when I don’t think 800 MHz does the trick. Of course you can perform the same settings on a regular desktop computer where you can lower the power consumption and thus lower the heat development. But the effect is not as striking in spacious chassis, and you’re not dependent of a battery in a regular PC.

For those of you who are still unsure of the pros when undervolting, we’ve compiled a list below. We have yet to find any cons, because as long as you evaluate the correct settings there shouldn’t be any.

Pros:
+ Lower processor temperature
+ Lower system temperature
+ Longer battery time
+ More settings (Throttling)

Cons:
– ?

After writing this article, my hands don’t feel as warm as they would have if I hadn’t performed the undervolting of my laptop. That’s all from me, good luck with the undervolting!

My hp laptop is getting shut down again and again, after changing its battery I am getting that issue again. what is the problem? what I should do to work it.
if you are using Bitdefender antivirus and having an issue then you can visit Bitdefender customer service for Bitdefender antivirus issues

I think it’s worth it. The stock voltage is generally overly cautious to ensure all CPU’s work reliably. However depending on the silicon lottery, lots of CPUs will run at a lower voltage, whilst still maintaining performance. Mine is a desktop, but I still shaved of 0.14v from the stock voltage (1.0v) of my Xeon and it dropped a few degrees when pushed hard. 0xc00000e9 So in a laptop it will definitely be worth it, with the caveat that it depends on the silicon, so some CPUs will accept lower voltage and some won’t, so make sure you thoroughly check… Läs hela »
