CPU Voltage Overclock help.
I'm trying to push my i5-3570K overclock, so I set it to 4.0GHZ and adjusted the BIOS voltage to 1.15. After testing with Prime95 and HWINFO64, the voltage came out at 1.295 at that speed. Why does it exceed the 1.15 setting I configured in BIOS? My system details are i53570K, MSI GD65 Z77, 8GB GSKILL Ares 1600, 750W 80+ GOLD, and MSI GTX560.
the fixed voltage issue isn't an issue.
at low frequencies, power use and heat production are significantly reduced.
some individuals opt for fixed voltage and fixed frequency in their 24/7 overclocking.
just a small amount of money spent on electricity each year.
Hey team, I'll check what you all talked about.
If someone adds more ideas, feel free to share.
So I was checking VID and after doing some research, it seems VID is the factory preset number that stays set, acting more like a rule for the CPU. Once you go overclock and manually adjust the CPU voltage, it can change that setting. To check the actual CPU voltage, I ran CPU-Z and it matched what my BIOS had set. Now, my motherboard doesn’t let me change the offset settings, so I have only two options: either keep the voltage constant at a fixed level or use Turbo Boost to overclock. The problem is that I can’t run the CPU at a lower fixed voltage while it still adjusts during use. Since my motherboard doesn’t support that, I’m stuck—either I have to find a custom 24/7 voltage for any chosen frequency, or let the CPU decide the voltage with Turbo Boost. It’s a hassle, and I won’t be able to reach higher clocks unless I stick to fixed voltage rates.

some users stick to fixed voltage and fixed frequency for continuous overclocking.
this only costs a few dollars a year on electricity.
so the CPU draws much less current when idle at a constant high voltage?
why is it beneficial to be able to lower the voltage, even if higher current is needed at low voltage to maintain the same power?
With a constant voltage, power consumption remains slightly greater during idle. Apologies, I’m too unmotivated to go over voltage versus current for too long. In summary, more current needs "denser" conductors, while higher voltage demands "more robust" insulation.
