i5 2500k overclocking questions, from a beginner.

[reboot]

here is my system

cpu: i2500k & Thermalright Ultra-120 Extreme CPU Heatsink
mobo: asrock z75 pro3
ram: ddr2133



for starters I looked at this guide:
http://www.overclockers.com/forums/...Beginners-How-to-set-your-25-6-700K-to-4-5Ghz
and this one:
http://www.overclock.net/t/1198504/...-guide-sandy-bridge-ivy-bridge-asrock-edition

then I started working on my overclock, but ive got some questions, here are the settings I changed:
multi to 45
Turbo Boost voltage increase +0.070V
offset volt +0.005V

attached is a screen shot of my hwmonitor, and cpu-z

looking at the monitor values i see cpu vcore at 1.320 max... I had expected to see 1.35... and when I raised the turbo boost voltage a little more this did not go up. Then looking at voltages under the i5 2500k portion i see voltages, VID 1.436V

I'm confused by these numbers, I understood from the guides that 1.35 even a little higher was safe for 24/7 use, my vcore is reading 1.32... but the VID is 1.436, is that too high?
whats the difference between VID and vcore?

So far my temps have not gone above 70 C in prime.

found this post, which seems to be a similar question

http://www.tomshardware.com/forum/268278-29-confused

im just trying not to blow up my cpu, while also trying to overclock it to 4.5 and im a total noob! any help would be appreciated!

have another image with 1 notch more voltage in the bios.

i found this too... http://www.overclock.net/t/1403679/i5-2500k-is-this-normal-vid/10

seems im doing ok... VID is nothign to worry about and my temps and vcore are in the area that people say are safe, so im testing prime for an hour.

 

[reboot]

so this seemed stable in prime, but i started noticing errors in windows any help would be appreciated.

For your overclock settings check out this thread...

And for VID vs Vcore, this is a good explanation:

And if you still have questions about safe ranges of VID and Vcore, you can check this out.
