I just wanted to know if there was a way to tell if a CPU was overclocked. I'm trying to purchase an i5-2500K from this mom & pop store near me and they have a decent price for it. They told it was just a 1-day return etc. Thanks and I appreciate the input.
You can't. OC settings are on the system BIOS, not internal to the chip. Once removed there is no record of the settings on the CPU.
Have them put the CPU in a machine and show you that it works, that would be my route.
