Ok so I've never overclocked a CPU or any other hardware before and I'm a little scared. The only reason I am overclocking is I've gotten the impression that I would be stupid not to overclock with "how easy" it is these days and I can get stable clocks that won't decrease the life of my CPU or so I've been told. I tried reading the core i5-2500k thread that is stickied in this forum and have a noobish question. From what I read I can up my multiplier to get higher mhz on my processor. It also sounded like I can tweak my voltage to get additional clocking out of my CPU.
The question is could I just change my mutliplier on my 2500k to something like 42 so I get 4200mhz and just call it good or do I have to tweak voltage and what not for that extra mhz to be stable? Basically I just want to get a little more out of my processor with as little chance possible of me screwing things up or decreasing my processor life. I'm far from someone that wants to get every little last drop out of his processor possible. I'm tempted to not OC, but I've heard that would be a mistake.
Raising the multiplier or BCLK (look up what's best for your CPU) for a mild overclock is perfectly reasonable. Just make sure you have adequate cooling. Adjusting voltages is to achieve the best and highest overclocks. For small overclocks it's not required.
and you can try trial and error as it should be overclocked by a beginner, remember overclock step by step, up slightly and then test the stability, if the result is a new stable overclock again and so on, and keep an eye on the temperature within reasonable limits
