I have recently build my first ever PC at 19 (I'm still excited). I got a 4670k, Noctua NH-D14 and a MSI z87-G45 Gaming mobo. I was quite interested to OC this as it's the first time I've had a PC with a decent CPU Cooler (my last PC had an E8400 on it to put it into perspective). I watched a decent video that got me to 4.2GHZ. http://www.youtube.com/watch?v=7mLP3pGvnDU
However I'm looking at going a little bit further as my full load temps on aida64 are less than 60 degrees. It's the voltages I'm worried about though, There are 2 settings - core voltage and ring voltage. Which one of these is the voltage when people refer to their overclock as 4.3 @ 1.2v? And why once I get to boot up does CPU-z show my voltage to be more than the 2 voltages I set (1.2 when I'm on firstname.lastname@example.org and email@example.com).
I guess I'm just a massive overclocking n00b. Any help would be greatly appreciated.
