I'm buying a new PC and going to build it myself here's specs

Gtx 970 msi

Ssd is a San disk ultra 240 gb

1 tb hdd

As rock 1150 z97x killer mother board

Super nova 750 watt b2 evga

Corsair 760t case

I5 4690k

And was wondering how to overclock it , also would it over clock good with that mother board or would it be better getting a different z97 , also need help picking a good CPU cooler air/water idm
 
is this your board? if so it is fine, I would get a hyper 212 evo unless you really plan to OC a lot. then get a h100i
overclocking on those chips is easy, boost the multiplier until you can get no higher, then raise the voltage if you want to go further, just remember, extra voltage = extra heat, so raise it in very small increments.

Overclocking is really simple.

There's an option on your motherboard BIOS called Multiplier.

You just change that to up your Frequency.

For the base i5-4690k, you'll have a 35 Multiplier with a Bus Speed (Frequency) of 100MHz

So that's 35 x 100 = 3500MHz

If you want to go to 4000MHz, you simply change that Multiplier to 40 (40 x 100 = 4000)

Of course you can change that Bus Speed from 100 to say 102, and get more, but it's better to keep it simple.

You may be able to change the Multiplier a little without changing voltage (Core Voltage), but as you get closer to the limit of your stable OC, every 1 multiplier you add (100MHz), you need 0.040 to 0.050v extra

Personally I'd try setting your multiplier to 40 with a 1.2v and see whether it's stable (it should be), then lower the voltage if you can.

So basically my main objective is to getting it to 4.0ghz other than 3.5

20% is a great OC, especially on air. That's 4.2GHz. Probably getting close to 1.3v for stability.

4GHz is just under 15% @ 1.2v

Ultimately you want to limit your voltage and heat generation to ensure a long life of your CPU. When you go above stock voltage (1v I think for your chip), you run the risk of shortening your chips lifespan.
 
Get as high as you can, and try to not break 1.25 volts. if that fails, then go up to 1.3 there are no set lines as to what to OC to. I OCed to 5.1 and then stopped? why because I got bored. one OCs as much as they want/need. so really, it is up to you you will see a good boost around 4.2 but further will still be nice.

Sure when I get all the parts It'll probably be easier to understand instead of just talking about it sense I'll actually be in the bios and stuff also so basically I wanna put the voltage at like 1.3 and keep highering the ghz until it won't let me go any more

"And see what you can get" so how do I know my limits
