How do I overclock I5-4670K with Asus Z87-K

Greetings,

I've only really had experience in the past with overclocking using a gigabyte board on a AM3 chip. It was easy, all I had to do was change the multiplier setting.

However, with my new setup, I have no idea what is what, there are a ton of different settings and it's not very clear (to me at least with my minimal amount of computer knowledge) how I'm supposed to overclock this thing?

Any help? :)

Thanks.

Ivy and Haswell chips simplest way to overclock is through the turbo option.

You should have a selection that shows your turbo mode set to Auto, change it to manual and enter a number. 100Mhz x a value that gets near your target frequency. You can also go through and disable C power states and Intel Speed Step for simplicity while you test.

Voltage wise I like to set it manually. For a quick test set the voltage to 1.2(watch your temperatures) and ramp the multiplier up until the computer becomes unstable. That is roughly the frequency you can reach. You can then begin fine tuning the voltage to reach better stability or make attempts at higher voltages/frequencies as long as temperature is good.

To have your computer run at turbo mode continuously, set Windows to high performance mode in the power options menu.

Thank you!

I can't believe I missed the 'ratio' part that would allow me to select the multiplier... It wasn't labelled like the last MOBO I had. :)

I set my voltage to 1.2 but the PC would constantly freeze.... Set the multiplier to 43, so its running at 4.3Ghz with the stock cooler but running Prime95 on torture mode is giving me CPU temperatures of 80C after a few minutes.

Whats the max temp I should go with this setup...??

(I'm aware I need a aftermarket cooler, but long story short I was lucky to talk my wife into getting what I have now, it will have to wait til August.)

edit; With CPUID, it shows it running at 4GHZ with the temp at 80C, but its not getting any hotter or faster. Is this, somewhat acceptable...??

80C is about the top end, you probably shouldn't go further.

1.2 volts is stock voltage, a bit odd that it wouldn't operate correctly. Without an aftermarket cpu cooler you could try undervolting to reduce temperatures. Perhaps 1.125 @ 4.0Ghz or something.
