noob need help for overclocking

[computerbuildin]

so I have an i5 2500k, I know the basics of OC'in, you have the base clock(which you shouldnt mess with unless you are doing something a little different with a multiplier, basically its just multiplied by this) your multiplier and your voltage. I noticed something a little different in this case, I have gone into my bios, its all 1 multiplier but when you use the extreme tuning utility it has a different multiplier for each core. I say I go into the bios to do this considering when I stress test it goes to 3.3 GHz which im pretty sure is the multiplier now. But anyway heres a screenshot of what it looks like with 4 different things. I dont think the screenshot will come up. But I think you get the idea. So my last question is, im taking small steps on this(which you should do for OC'ing) and im looking to just hit atleast 3.8 or so today, will go higher later. at what point do I need to up the voltage?

For 3.8, stock volts should be fine. I think you would need to start upping voltages starting at around 4.1-4.2, depending on your chip.

You are right to a degree, you shouldn't go straight for 5.5ghz but working your way up .1mhz at a time is a bit of a waste of time. Set the multi to x42 (4.2ghz) set the voltage to either 1.3v if you are using manual voltage or +0.050 if you are using offset and stress test it.

If you are happy with 4.2ghz you can start trying to drop the voltage until you find the point when it becomes unstable then bump it back up a tick or 2 or up the multi to x44 with a small voltage bump and start working on stability from there.

To answer your question about when to up the voltage the plain and simple answer is when your system crashes during stress testing, you only add voltage to an overclock to make it stable no other reason. Use prime 95 for a couple of hours or intel burn test set to very high and 100 consecutive runs to check if you are stable each time you tweak anything.
