Hi i was wanting to know if someone could tell me how to properly overclock my core i5 2500k processor should i use Turbo Boost or OC Genie or just go about it another way?

Use turbo boost multiplier
and set + offset vcore
normaly any 2500k does 4.2GHz @ default voltage/unchanged/auto
but this very depending on chip quality and cooling.
Normaly you shouldnt go over 85c on stress testing and day to day you should be around 60c and idle around 35c

Heres few example guide to help you further:

There are a couple of things you need to make sure.

First- Is your cooler adequate enough to overclock?

Second- How good is your cooler and have you checked the reviews of the cooler?(To have a good idea of the ideal temperature and OC range you can get.)

Third- After checking everything, you can come back and read these guides. It is fairly informative. If after all this and you still don't get it or you are unsure and not confident, come back here.

When overclocking my cpu do i need to enable or disable enhanced intel speedstep in the bios?

Disable that for sure. Some people rather it be enabled for some odd reason. I disagree. Disable that feature and you'll be better off for it. All it does is lower you clock speed when you CPU is not loaded. I prefer my clockspeed to be fixed at whatever my multiplier is. If I set my multi to 45 then I'll be at 4.5Ghz. I much rather that then my CPU throttling up and down and up and down.

Disable turbo boost. Even if you disable turbo boost, your motherboard with still say that your multiplier is 34 and turbo boost will be whatever your overclock is(at least my mobo does this). Although turbo boost will really be disabled. The reason you want this disabled is because if you have this on, and set at say, 4.5Ghz, the only time your CPU will actually get to 4.5Ghz is if your maxed out on one of your cores. If your maxed out on 2 cores it'll only go to 4.4, if you maxed out on 3 I think you'll only go to 4.2, and if you maxed out on all cores it'll go to something like 4.0Ghz. But if you disabled turbo boost and set your multiplier to 45, the if one cores maxed out it'll go to 4.5Ghz and if all 4 cores are maxed out it'll go to 4.5Ghz also, or whatever your multiplier is set to.

I don't like to just give the answer. It's better to explain everything so you actually know what your doing and you know the reason for it.

Edit: You also need to disable all C states and any kind of power saving technology. You also need to turn off core parking. You can't do this in the BIOS. You either do a registry hack(which I won't explain you can look it up) or you can download core parking control. It allows you to turn this feature off, then exit the program, and it'll stay off. What this feature does, is it disables any core that isn't being taxed. And when the cores are needed, they get turned on. The problem with the power saving features is that it takes time to turn all these things on and off. Although it takes very little time, this may cause stuttering during games and some lag in programs and benchmarks if they hit your CPU hard then let up then hit it hard again. I highly recommend turning this feature off, if only for peace of mind knowing that the 4 cores on your CPU are actually always being used and distributed across evenly.
