Check VCore or VID when overclocking

[mafulynch]

HI, I have a 6700k cpu and trying to overclock for first time. I wanted to know what should I check when stress testing, if the VCore or the VID, since VID goes way higher than what I set in my bios (about 0.1v above). for example if I set core voltage in my bios to 1.32 on hwmonitor i se VID go to 1.36v and even 1.402v. Also, what would be a safe voltage for a 24/7 use? Should I use LLC? because I am having a lot of trouble going from 4.4 to 4.5 and have to really go high on voltage unless I use llc on high.
Thanks

I would suggest 1.4V max, with LLC set to "medium" or "high" but not "ultra high" or "extreme." Too much LLC will cause the voltage to jump higher than what you set, but not enough and you'll have the opposite problem, Vdroop. Vdroop is when the voltage drops under load, which is very bad for overclocking.

As for the voltage jumping around, are you using manual, offset, or adaptive mode? If you're using manual, and it sounds like you are, then the voltage is going up because of your LLC setting.

HWMonitor is not the best tool for monitoring core voltage, since it often mislabels and misplaces these voltages. I'd suggest AIDA64 for more reliable monitoring. Make sure that your combination of voltage selection and LLC setting does not cause the CPU to go above 1.4 for 24/7 use.

Vcore is what your cpu is getting and what you pay attention to. VID is what is being sent to the mobo which will be higher.

When you say to make sure it doesn't go above 1.4 with LLC and voltage combination you mean vcore doesnt go above 1.4 or VID?

Vcore - but don't go by HWMonitorPro - on my system, HWMonitorPro mislabels the Vccin as Vcore, and thus reports it as 1.88.
