UNDERVOLTING
So first discuss about what is undervolting, Itis a process through which voltage to computer processors and components is decreased dynamically on run-time. And within dynamic voltage scaling that enables conserving electric voltage to reduce energy consumption and heat produced by computing components (i.e cpu and gpu). So basically in simple words It means providing your cpu less voltage than the recommended voltage to reduce the heating (or thermal throttling).
IS UNDERVOLTING SAFE?
Undervolting your CPU is completely safe. There is no physical/electrical mechanism associated with undervolting that can cause damage to your CPU. But. there are some things you should know and be aware of when you are undervolting your CPU. When CPUs are manufactured, there are variations in the manufacturing process that produces CPUs that can achieve different maximum clock frequencies ( i.e some are faster and some are slower than others). The manufacturer tests these CPUs and finds which ones are faster and which ones are slower, labels them and sells them at different prices even though they may have all been produced exactly the same. However, when they say that a CPU will work at a certain frequency, lets say 2 Ghz, this really means that they have tested that the chip will work at this frequency plus some margin of error (say 10% or 2.2 Ghz (I cannot say what margin of error Intel uses in its manufacturing test)) at the worst case operating voltage and the maximum operating temperature. The lower the voltage ,the lower the operating frequency. Additionally, note that the highest operating temperature as the hotter the CPU is, the slower it runs. CPUs when first turned on typically operate at room temperature (or about 25 degrees C) but are typically speeded at a maximum operating temperature of 85 degrees C (or sometimes hotter). If you could somehow keep the processor closer to 25 degrees C, it would certainly run at a higher clock frequency than if it heats up to 85 degrees C.
PROS
So my ending thoughts about this post are, UNDERVOLTING is completely safe, it can't harm your system components. If you give your cpu too less voltage then BSOD will appear which is also completely safe, it will just shut down your system. So if your cpu goes above 90 degree C and thermal throttling is there, then i will recommend undervolting for lower temps and better performance. Hope you guys have loved it, stay tuned till next post. See you later... EXTRA TIP If you want to get lot better temps try repasting your cpu and gpu with undervolt. stock paste are useless, manufacturers mainly don't focus on pasting. So repaste your cpu and gpu with good thermal pastes that you can easily find in amazon or flipkart. |
