Question about voltages when overclocking

[XdbodzX]

Hi so I'm overclocking my i5-3570k and seem to have it stable at 4.5 GHz with a +0.035 V offset.

The only issue is that I'm trying to research what other people have been able to achieve with the same CPU and lots of them have the raw voltage instead of the offset.

I've tried to use CPU-Z to find what CPU voltage mine is running at however it keeps on changing around depending on what my PC is doing. I cannot remember what it's called exactly (speedstep i think) but enabled on my PC is an intel option that changes the CPU frequency depending on the load. When idle, the cpu is at 1.6 GHz but under load it uses my overclock at 4.5 GHz. Should I have this option enabled for overclocking or is this a bad idea?
I've looked at the intel website and cannot find the stock voltage anywhere.

Should I be forcing a constant voltage at all times?
How can I find out my stock voltage so I can just add 0.035V to it to find my stable OC voltage?


Thanks a lot,
Dan.

The changing of frequencies happens at stock settings. Keeping voltages at a constant is best for a high, but stable overclock. LLC (load-line calibration) set to its highest setting will make it so that the voltages don't change at all, and prevents voltage droop. Keep in mind setting LLC to a high setting will greatly exaggerate your idle and load temps since it's feeding the CPU a CONSTANT voltage. It's not inherently bad just something to keep the system more stable.

Stock voltage depends on the motherboard, but most of the time it's best to find out what voltage your CPU will be stable at, and then use off-sets to fine tune your voltage for optimal performance.
