alright, so i'm looking at overclocking my I5 2500 (NON- K) with system voltages, not BCLK and whatnot, if i can help it i'll use it if i have to . i understand that it's not quite as easy as bumping up the core multiplier as it would be with a 2500k. i'm using a P8Z68-V i am running:
Motherboard: ASUS P8Z68-V
Power supply: Strider Essentials 600w
Graphics: EVGA GTX570SC
Processor: i5-2500 HD2000 Graphics
RAM: G. Skill DDR3-2133 mhz PC3-1700 Dual channel 4096 (4GB X 2) 9-11-10-28 1.65V
Blck and multiplier are the only ways to overclock sb. If you are not raising blck then you have to raise the multi. In your case you are limited to only ocing 400mhz without touching the blck. Raising voltages is only for stability which should not be necessary at that speed.

Not quite as easy? Try impossible.
You can't overclock that processor, that's the whole point of a k series chip. All you can do with that one is raise the BCLK, which SB chips are extremely intolerant to. At best you could get another 100 MHz out of it, and even that's pushing it.
If you want to overclock, you need a new processor. Sorry.
